Glossary of Investigative Interviewing Terms

ACCESS Model

The ACCESS Model is an externally developed investigative cycle with six stages: Assess, Collect, Collate, Evaluate, Survey, and Summarize (Summarise in the original British spelling). Jones, Grieve, and Milne (2008) attribute its development to Eric Shepherd and Mortimer (1999). ASC integrates it as a tool inside the Compass’s Route direction to connect each interview to the wider investigation. ASC did not create the acronym, the stages, or the underlying cycle.

Teach To Talk supplies the interview standard inside ACCESS, so that what is collected in the room arrives with its source, certainty, and limits clear enough to collate and evaluate.

Adaptive Strategies Compass

The Adaptive Strategies Compass is the navigation tool inside Teach To Talk. When an interview starts to struggle, it tells you which way to turn. It has eight directions and four navigation decisions (stay, shift, stack, stop).

Every interviewer eventually hits the moment when the conversation stalls: answers shrink, rapport slips, a topic goes quiet, or the account collides with the evidence. Most training answers that moment with one move: push harder. The Adaptive Strategies Compass asks why first. Eight directions, no fixed order, one for each reason an interview struggles, point the interviewer to the move that fits. It is one framework for victims, witnesses, and suspects, because it reads the condition, not the role.

• Teach: Do they know how to do this?
• Listen: Is this still their account?
• Retrieve: Is there more they genuinely remember?
• Clarify: Do I understand what they mean, and how they know it?
• Adapt: Is how I’m communicating working for this person?
• Re-engage: Can they answer, but won’t?
• Test: Does the account hold up against the evidence?
• Route: Where is this conversation going?

Eight directions, no fixed order. Move to whichever one the conversation needs, as often as it needs it.

Directions are named for tasks. Established research methods are credited tools inside the directions, not ASC’s own: the Cognitive Interview (Fisher & Geiselman) in Retrieve, Strategic Use of Evidence (Granhag, Hartwig & colleagues) in Test, and the ACCESS Model (Shepherd & colleagues) in Route, with the PEACE framework (England and Wales) informing Route, Clarify, and Test. The Compass is practitioner-developed, research-informed, and proposed for evaluation. It is not a validated diagnostic or decision instrument, and as an integrated framework it has not yet been independently validated.

The Adaptive Strategies Compass is a trademark of Advanced Strategic Communications.

Affidavit

An affidavit is a written statement of fact, signed under oath or affirmation before a person authorized to administer oaths, typically a notary public, judge, or law-enforcement officer with statutory authority. The affiant attests that the contents are true to the best of their knowledge, and the document carries the same evidentiary weight as sworn courtroom testimony.

In the search-warrant context, an affidavit is the foundational document a law-enforcement officer submits to a neutral magistrate to establish probable cause. The affidavit must lay out the specific facts and reasonable inferences supporting the conclusion that evidence of a crime will be found in a particular place at a particular time. Conclusory assertions or boilerplate language are insufficient; a reviewing court evaluates whether the affidavit, read in its four corners, supplies a substantial basis for the magistrate’s probable-cause determination.

Affidavits also support arrest warrants, complaints, and various civil filings. Because affidavits are made under penalty of perjury, accuracy and precision in describing the source of each fact, firsthand observation, informant statements, physical evidence, or interview testimony, are essential. Defective affidavits can lead to suppression of evidence under the exclusionary rule, making careful, well-corroborated drafting a core investigative skill.

Aguilar-Spinelli

The Aguilar-Spinelli test, drawn from Aguilar v. Texas and Spinelli v. United States, is a two-pronged standard for evaluating whether information from a confidential informant supports probable cause. It asks the magistrate to assess both the informant’s veracity (why the informant should be believed) and their basis of knowledge (how the informant came to know the information).

At the federal level the rigid two-pronged test was replaced by the totality-of-the-circumstances approach of Illinois v. Gates (1983), under which a weakness in one prong can be offset by a strong showing on the other or by independent corroboration. Some states retain a stricter Aguilar-Spinelli standard, so affiants should know which framework governs in their jurisdiction.

Barrier Assessment

The barrier assessment is the broad check in the Compass’s Re-engage direction for difficulties involving the interviewer, the person, the task, and the conditions, run after the first five “Which way?” questions have been considered. It can lead to clarification, an adjustment, support, a pause, or stopping.

It does not itself establish unwillingness. Barrier Mapping has the narrower, willingness-related purpose and is used only after the barrier assessment supports a willingness barrier.

Barrier Mapping

Barrier Mapping is the core tool of the Compass’s Re-engage direction, used only after the barrier assessment supports a willingness barrier. Fear, Shame, Loyalty, Distrust, and Reactance are recurring hypotheses, not an exhaustive list, personality types, behavioral tells, or diagnoses. The interviewer checks the condition with the person and selects a proportionate response without supplying an excuse or minimization.

A barrier is a working hypothesis to explore with the person, never a label inferred from demeanor. Its responses draw on procedural-justice, reactance, self-determination, and Motivational Interviewing research, none of which validates it. Barrier Mapping is practitioner-developed and research-informed, and has not been independently validated.

Clean Question Test

The Clean Question Test is the question review taught in the Compass’s Listen direction: ask one understandable thing at a time; identify information supplied by the interviewer; leave room for disagreement, correction, qualification, or uncertainty; and preserve the source and limits of the information.

Deliberately introducing a topic or evidence is permitted when appropriate, but its origin and effect on the account must remain clear.

Cognitive Interview

The Cognitive Interview is a research-based protocol for questioning cooperative witnesses and victims, developed by psychologists Ronald P. Fisher and R. Edward Geiselman and first published in 1984. It was designed to address the shortcomings of standard police interviews, which tend to interrupt witnesses, rely on closed questions, and prematurely narrow recall.

The original protocol consists of four core memory-retrieval techniques: mentally reinstating the context of the event, instructing the witness to report everything regardless of perceived importance, recalling events in different temporal orders, and recounting them from different perspectives. These techniques are grounded in two principles from cognitive psychology, the encoding-specificity principle, which holds that retrieval is most effective when retrieval cues match those present at encoding, and the multiple-trace hypothesis, which holds that memories can be accessed through different routes.

The Cognitive Interview is one of the most extensively researched interviewing methods, shown to increase correct detail while keeping accuracy comparable. Decades of empirical research have found that it produces substantially more correct details than standard interviews, with comparable or only modest increases in incorrect details when conducted properly. The protocol has been adapted for child witnesses, older adults, and trauma survivors.

ASC teaches the Cognitive Interview as a credited tool in the Compass’s Retrieve direction, run on the Teach To Talk standard. ASC limits change of perspective to vantage points the person actually occupied, and never asks a person to imagine what someone else saw. Teach To Talk does not rename the Cognitive Interview or inherit its validation.

Communication Adaptation

Communication Adaptation is the core tool of the Compass’s Adapt direction: an observation-and-feedback process for adjusting the conversation to a person’s observable communication needs. It uses four moves, Observe, Consider, Adjust, and Verify, and treats communication behavior as information about the exchange, not a personality label or a judgment about the person.

The interviewer observes pace, language, detail, turn-taking, organization, social energy, and processing space against the person’s communication baseline; considers explanations involving the person, the interviewer, the task, and the conditions; makes the smallest reasonable adjustment; and keeps it only when it improves understanding, participation, rapport, or information quality.

Communication Adaptation guides process adjustments only. It is not used to diagnose personality, predict behavior, or assess credibility or deception, and it is not a validated assessment instrument. It does use DISC, a communication-style model tracing to William Moulton Marston, as a working style hypothesis to guide rapport, tested by whether the adjustment helps.

Communication Baseline

A communication baseline is how a person ordinarily communicates earlier in the same interview: their pace, the detail they offer, how they use silence, their posture and tone. A change from the baseline tells the interviewer that the conversation needs attention, never why, and never whether the person is lying. It is not a behavioral baseline for detecting deception.

The baseline is what makes the Observe move of Communication Adaptation meaningful. A change is a prompt to check and adjust: slow down, clarify, take a break, rebuild rapport, or return to the topic later. Observation manages the conversation. Evidence tests the account.

Confabulation

Confabulation is the production of fabricated, distorted, or misinterpreted memories without the conscious intent to deceive. The confabulator genuinely believes the recounted information is accurate, even when it is demonstrably wrong. The phenomenon was first studied in clinical neurology in patients with frontal-lobe damage and Korsakoff syndrome, but it is now recognized as a normal feature of human memory under certain conditions.

In the interview setting, confabulation often arises when a witness feels social pressure to provide a complete account and unconsciously fills gaps in memory with plausible inferences, prior knowledge, or material absorbed from outside sources. Suggestive questioning, repeated retelling, and leading prompts substantially increase the likelihood of confabulated detail entering the record. Because the witness is sincere, confabulated content can be persuasive and resistant to correction.

Distinguishing confabulation from intentional deception, and from the ordinary forgetting and reconstructive nature of memory, is one of the central tasks of evidence-based interviewing. Open-ended questioning, the funnel technique, careful attention to the source of each detail, and avoidance of suggestion are the primary safeguards against introducing confabulated material into a witness statement.

Custodial Interrogation

Custodial interrogation is questioning initiated by law-enforcement officers after a person has been taken into custody or otherwise deprived of freedom of action in any significant way. The phrase comes from the U.S. Supreme Court’s 1966 decision in Miranda v. Arizona, which held that the Fifth Amendment privilege against self-incrimination requires procedural safeguards once both elements, custody and interrogation, are present.

The custody determination is made objectively, based on whether a reasonable person in the suspect’s position would have felt free to terminate the encounter and leave. Courts consider factors such as the location of the questioning, its duration, the number of officers present, whether physical restraints were used, the language used by the officers, and whether the person was told they were free to go. A formal arrest is sufficient but not necessary, a functional restraint comparable to arrest will also trigger Miranda requirements.

The interrogation prong covers both express questioning and any words or actions that officers should know are reasonably likely to elicit an incriminating response, as articulated in Rhode Island v. Innis, 446 U.S. 291 (1980). Statements obtained during custodial interrogation without a valid Miranda waiver are generally inadmissible in the prosecution’s case-in-chief.

DASA (Dignity for All Students Act)

The Dignity for All Students Act (DASA) is a New York State statute, enacted in 2010 and effective July 1, 2012, that requires public elementary and secondary schools to provide students with a learning environment free from discrimination, harassment, and bullying. The law is codified in New York Education Law Article 2 and was amended in 2013 to expressly include cyberbullying.

DASA covers conduct based on a broad range of protected characteristics, including actual or perceived race, color, weight, national origin, ethnic group, religion, religious practice, disability, sexual orientation, gender (including gender identity and expression), and sex. Each school district must designate at least one Dignity Act Coordinator, train staff, adopt policies, and investigate reports promptly and thoroughly.

From an investigative-interviewing standpoint, DASA matters generally involve student complainants, student respondents, and student witnesses, often in close peer or social-media networks. Interviews must balance the procedural requirements of the law with developmental, trauma-informed, and confidentiality considerations appropriate to a school setting. Findings are documented in writing and form the basis of remedial and disciplinary action under district policy.

DISC (style read)

DISC is a communication-style vocabulary that traces to William Moulton Marston’s work in the 1920s (D, direct; I, outgoing; S, steady; C, careful). ASC uses it for a style read: a working guess about a person’s communication style, formed early in the interview from two cues, pace and focus. The interviewer adjusts and verifies; if the adjustment does not help, the read is dropped.

Pace is fast and outgoing, or measured and reserved; focus is on tasks and facts, or on people and relationships. A style read is a hypothesis, never a finding: it does not enter the record as a conclusion about the person, bear on credibility, or predict behavior. DISC is used here as a communication vocabulary, not a validated assessment instrument, and its value is measured by whether the adjustment improves the conversation.

Disclosure Ladder

The Disclosure Ladder is ASC’s name and operational packaging for three possible evidence-communication rungs: a future-tense inquiry before disclosure, soft confirmation, and direct presentation. The future-tense inquiry is asked only about evidence the interviewer actually holds or can lawfully obtain. Soft confirmation acknowledges, accurately and without revealing the source or the details, that there is a real basis for the concern; it is never a bluff.

The Ladder builds on established work. Its underlying principles (account-first, delayed, incremental, and strategically framed disclosure) come from Strategic Use of Evidence (Granhag, Hartwig & colleagues). The evidence plan controls whether the Ladder is used and where it begins; no interviewer is required to climb every rung, and direct disclosure may be required or preferable. Source-neutral questions, asked during account development, come before the future-tense question.

It is a tool of the Compass’s Test direction, used after the Difference Audit and the Fair Challenge Test. It is not SUE’s Evidence Framing Matrix, SUE research does not validate it, and it is never paired with an evidence ploy, an exaggeration, or a false claim.

Enhanced Cognitive Interview (ECI)

The Enhanced Cognitive Interview (ECI) is a refined and expanded version of the original Cognitive Interview, developed by Ronald Fisher, R. Edward Geiselman, and colleagues in the late 1980s and described in their 1992 monograph Memory-Enhancing Techniques for Investigative Interviewing. The ECI was designed to address practical limitations identified when the original protocol was deployed in field settings.

In addition to the four core memory-retrieval techniques of the original Cognitive Interview, the ECI adds explicit emphasis on rapport-building, transferring control of the conversation to the witness, witness-compatible questioning that follows the witness’s mental representation of the event, careful management of interviewer expectations, and structured open-ended prompts. Closed questions are reserved for clarification and are sequenced to avoid contaminating later free recall.

Meta-analyses (Köhnken, Milne, Memon & Bull, 1999; Memon, Meissner & Fraser, 2010) found substantially more correct details, a smaller increase in incorrect details, and accuracy rates similar to standard interviews. The ECI informs witness interviewing within the PEACE framework in England and Wales, and is used in Norway, New Zealand, and a growing number of U.S. agencies.

Enhanced TEACH

Enhanced TEACH is the complete TEACH opening adapted for interpreted, remote, complex, vulnerable, highly consequential, or communication-intensive interviews. It includes expanded access assessment, slower delivery, multiple practice checks, explicit sector boundaries, carefully selected signals, and planned reassessment after breaks or status changes.

It is one of three TEACH delivery modes, with Standard TEACH and Rapid TEACH.

Exclusionary Rule

The exclusionary rule is the doctrine that evidence obtained in violation of a defendant’s constitutional rights, most often the Fourth, Fifth, or Sixth Amendment, is generally inadmissible in the prosecution’s case-in-chief. Its purpose is to deter unlawful government conduct by removing the incentive to obtain evidence improperly.

The rule reaches not only evidence seized directly but also evidence derived from the violation, the fruit of the poisonous tree, subject to exceptions such as inevitable discovery, independent source, attenuation, and good-faith reliance on a warrant later found defective. For investigators, the practical lesson is that how evidence is obtained can matter as much as what is obtained.

Fair Challenge Test

The Fair Challenge Test is ASC’s practitioner-developed set of seven checks applied before a difference between a person’s account and the evidence is put to them:

1. Materiality: Does the difference matter to the investigation?
2. Reliability: Is the information reliable enough to raise?
3. Accuracy: Can the interviewer describe it without overstating what it shows?
4. Preservation: Has the person’s original account been recorded?
5. Purpose: Is there a legitimate reason to raise it now?
6. Fairness: Is the interviewer genuinely prepared to hear any explanation, including one that clears the person?
7. Safeguards: Are voluntariness, comprehension, representation, vulnerability, privacy, and legal requirements protected?

A challenge that cannot pass is not made in its present form; the interviewer returns to Clarify, Route, or the evidence plan.

The test follows the Difference Audit, which asks whether the two pieces of information concern the same event, time, and vantage point; what kind of source each rests on and how certain each is; whether important words carry the same meaning; and whether anything said or seen since affected the later statement. The audit is about understanding the difference, not requiring the two to match: differences in source, certainty, or perspective must be understood, but they do not by themselves prevent a comparison. A difference that turns out to concern a different event, time, or meaning, or that the interviewer introduced, goes back to Clarify.

Both are ASC tools of the Compass’s Test direction. Neither has been independently validated, and passing both does not make a difference proof of deception.

False Confession

A false confession is an admission to a criminal act that the confessor did not in fact commit. Researchers Saul M. Kassin and Lawrence S. Wrightsman proposed an influential typology in 1985 that identifies three categories: voluntary, in which the confessor comes forward without external pressure, often due to mental illness, notoriety-seeking, or to protect another person; compliant, in which the confessor knowingly admits guilt to escape an aversive interrogation or obtain a perceived benefit, while privately knowing they did not commit the act; and internalized, in which the confessor comes to believe, at least temporarily, that they actually committed the offense.

False confessions are well documented in the post-conviction record. The U.S. National Registry of Exonerations and analyses of DNA exonerations by the Innocence Project have repeatedly identified false confessions among the leading contributors to wrongful convictions, particularly in homicide cases and cases involving juveniles or people with intellectual disabilities.

Risk factors include lengthy and confrontational interrogations, the presentation of false evidence, minimization tactics, sleep deprivation, and youth or cognitive vulnerability. Recording interrogations in full, restricting deceptive tactics, and adopting non-coercive interview frameworks are among the safeguards now widely recommended in academic and policy literature.

Focus Notes (PLATO)

Focus notes are the jot notes taught in the Compass’s Listen direction: only the PLATO words the person gives (People, Locations, Actions, Time, Objects), written in the order the person mentions them, with corrections and additions kept distinguishable from the original entries.

They support listening, the summary, and follow-up; they are not a transcript. Any further documentation, such as exact wording that carries evidentiary weight, is a separate record-keeping duty. PLATO is a training mnemonic that ASC does not claim; ASC claims only its selective, source-bounded use as an interview roadmap.

Forensic Interviewing

Forensic interviewing is a structured, legally defensible method of obtaining a reliable account of suspected abuse, neglect, or exposure to violence, most commonly from child victims and other vulnerable witnesses. It differs from broader investigative interviewing in its setting, protocols, and legal context: forensic interviews are typically conducted by specially trained professionals at child-advocacy centers (CACs), in multidisciplinary team settings that include law enforcement, child-protective services, prosecutors, and medical providers.

Several recognized protocols guide forensic interviewing of children, including the National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol, the ChildFirst (formerly Finding Words) protocol, and the RATAC protocol developed by CornerHouse. Common features across these protocols include a neutral introduction, rapport-building, narrative-event practice, open-ended free recall, and careful clarification with minimal suggestion.

Forensic interviews are generally electronically recorded so the resulting account can be reviewed, validated, and entered into evidence. The objective is not to confirm a hypothesis but to document the child’s account in a manner that minimizes contamination, supports the child’s well-being, and produces evidence that can withstand scrutiny in administrative, civil, and criminal proceedings.

Franks Hearing

A Franks hearing, from Franks v. Delaware (1978), is a proceeding in which a defendant challenges the truthfulness of statements in a search-warrant affidavit. To obtain one, the defendant must make a substantial preliminary showing that the affiant knowingly, intentionally, or with reckless disregard for the truth included a false statement, or omitted a material fact, that was necessary to the probable-cause finding.

If, after the hearing, the affidavit’s remaining content does not establish probable cause once the false material is set aside or the omitted material is included, the warrant is voided and the fruits of the search are suppressed. The doctrine is why accuracy and candor in affidavit drafting, including the duty to disclose material adverse facts, are not optional.

Funnel Technique

The funnel technique is a question-sequencing approach that begins with broad, open-ended invitations to talk and progressively narrows toward specific, focused questions. The opening question (“Tell me, in your own words, everything that happened from the beginning”) is the widest part of the funnel; follow-up questions probe particular topics surfaced by the witness; targeted clarification questions sit at the narrow end.

The technique is grounded in two principles supported by memory research. First, free recall produces the most accurate information, because the witness retrieves details directly rather than confirming or denying details supplied by the interviewer. Second, premature use of specific or yes/no questions can lead the witness, contaminate memory, and shut down narrative flow. By drawing out the full account before narrowing, the interviewer preserves the witness’s own wording and structure.

The funnel technique is a foundational element of the Cognitive Interview, the Enhanced Cognitive Interview, the PEACE Model, and modern forensic interviewing protocols. It is taught both as a question-design discipline, how to phrase prompts, and as a planning discipline, in which interviewers map out the topics they need to cover and decide the order in which to fund each one to its narrow end.

Investigative Interviewing

Investigative interviewing is the discipline of questioning victims, witnesses, and suspects with the objective of gathering accurate, complete, and reliable information about an event under investigation. Unlike older confession-driven models of interrogation, investigative interviewing prioritizes information over admission, treats the interview as an ongoing search for truth rather than a tool for confirming a pre-formed hypothesis, and is grounded in cognitive psychology, memory science, communication research, and human-rights standards.

The modern field has been shaped by the development of the Cognitive Interview by Fisher and Geiselman (1984), the introduction of the PEACE Model in the United Kingdom in the early 1990s, the Strategic Use of Evidence framework associated with Granhag and Hartwig, and the 2021 publication of the United Nations Méndez Principles on Effective Interviewing for Investigations and Information Gathering, which articulate a non-coercive, rapport-based, science-grounded standard.

Investigative interviewing is practiced across law enforcement, regulatory bodies, military and intelligence agencies, attorneys, internal-affairs and corporate-investigations functions, Title IX and DASA investigators, and human-resources professionals. Its core skill set, planning, rapport, open-ended questioning, evidence handling, and structured documentation, transfers across all of these contexts.

Leading Question

A leading question is a question that suggests its own answer, embeds an assumption, or introduces a fact that the witness has not previously stated. “Was the car red?” is leading where the witness has not yet mentioned the car’s color; “What color was the car?” is non-leading. In its most problematic form, a leading question presupposes a contested fact (“When you saw the gun, where was he standing?”) and invites the witness to accept that fact as part of their answer.

The cognitive risk of leading questions was established by the misinformation-effect research of psychologist Elizabeth F. Loftus, whose work in the 1970s and after demonstrated that post-event information introduced through suggestive questioning can alter, supplement, or replace original memory traces. Once misinformation is incorporated, the witness may report the suggested detail with confidence, and the original memory may be difficult or impossible to recover.

Because of this risk, modern interview protocols restrict leading questions to narrowly defined clarification roles, sequence them late in the interview after open-ended recall is exhausted, and document them carefully in the interview record. In the courtroom, leading questions are governed by rules of evidence (for example, Federal Rule of Evidence 611(c)) that generally prohibit their use on direct examination of friendly witnesses.

Memory Contamination

Memory contamination is the introduction of post-event information into a witness’s account through external influence, such that the resulting memory no longer reflects the witness’s original experience alone. Sources of contamination include suggestive questioning by interviewers, conversations with co-witnesses, exposure to media coverage, repeated retelling, and the passage of time.

The phenomenon is well established in cognitive psychology. Memory is not a recording of events but a reconstructive process; each time a memory is retrieved, it is also subject to revision based on current context, beliefs, and information available at retrieval. The misinformation-effect studies of Elizabeth Loftus and her colleagues demonstrated that even subtle changes in question wording, for example, the difference between “hit” and “smashed” in a question about a car accident, can shift a witness’s subsequent recollection.

Contamination is largely irreversible, which is why prevention is the central concern in interview design. Prompt interviewing, separation of co-witnesses, recording of interviews, careful question sequencing through the funnel technique, and minimization of leading or suggestive language are standard safeguards. When contamination is suspected, documenting how and when the post-event information was introduced is essential to evaluating the resulting statement.

Memory Encoding

Memory encoding is the cognitive process by which sensory experience is transformed into a stored mental representation that can later be retrieved. Encoding is selective rather than complete: the perceptual system processes only a subset of available information, shaped in real time by attention, prior knowledge, expectations, emotional state, and physiological arousal.

Researchers commonly distinguish among sensory encoding, short-term encoding, and long-term encoding, and among visual, acoustic, and semantic encoding modalities. The depth-of-processing framework introduced by Craik and Lockhart (1972) holds that information processed for meaning is generally encoded more durably than information processed only for surface features. Stress and trauma can also affect encoding through the action of cortisol and adrenaline, sometimes producing vivid central detail at the expense of peripheral detail, a pattern often described in the eyewitness literature.

For the investigative interviewer, the practical implication is that two witnesses to the same event may sincerely retain very different details, that gaps and inconsistencies are not by themselves evidence of deception, and that retrieval techniques must be designed to match the way the memory was originally encoded. The encoding-specificity principle is one of the theoretical foundations of the Cognitive Interview.

Méndez Principles

The Méndez Principles, formally the Principles on Effective Interviewing for Investigations and Information Gathering, are principles for non-coercive, rapport-based interviewing, published in 2021 by an international group of experts co-chaired by former UN Special Rapporteur on Torture Juan E. Méndez. They draw on research linking coercive interrogation to unreliable information and false confessions.

The Principles emphasize a presumption of truthfulness, thorough planning, rapport, open-ended questioning, and safeguards for vulnerable persons. They align closely with the information-gathering approach ASC teaches and with frameworks such as the PEACE Model and the Cognitive Interview. That alignment does not validate Teach To Talk or the Compass.

Miranda Warning

The Miranda warning is the advisement of constitutional rights that law-enforcement officers in the United States must give to a suspect before custodial interrogation. The requirement was established by the U.S. Supreme Court in Miranda v. Arizona, 384 U.S. 436 (1966), as a procedural safeguard for the Fifth Amendment privilege against self-incrimination.

The warning informs the suspect that they have the right to remain silent, that anything they say can be used against them in court, that they have the right to an attorney, and that an attorney will be appointed if they cannot afford one. While the precise wording can vary by jurisdiction, the substance of these four advisements is constitutionally required.

Miranda is triggered only when both custody and interrogation are present. A statement obtained during custodial interrogation without a valid waiver of these rights is generally inadmissible in the prosecution’s case-in-chief, although it may be used for impeachment in some circumstances. Subsequent decisions including Edwards v. Arizona (1981), Berghuis v. Thompkins (2010), and Vega v. Tekoh (2022) have further developed the doctrine’s contours regarding waiver, invocation, and remedy.

Nexus

In search-warrant law, nexus is the connection between the items sought and the specific place to be searched. Probable cause that a crime occurred, and probable cause that a particular person committed it, do not by themselves establish that evidence of the crime will be found in this place, right now. Nexus is the link that supplies that final step.

Nexus can be shown by direct observation, controlled activity, a reasonable inference from the nature of the offense that is tied to the specific offender and crime, or, for digital evidence, an articulated reason the data would be on a particular device or account. Nexus decays with time, which is why it and staleness so often fail together.

Open-Ended Question

An open-ended question is a question that invites a narrative response and cannot be answered adequately with a single word, a number, or a yes/no. “Tell me what happened” and “Describe what you saw next” are open-ended. By contrast, a closed question (“Were you in the room?”) limits the response set, and a forced-choice question (“Was the light on or off?”) restricts the witness to options supplied by the interviewer.

Empirical research has consistently shown that open-ended questions yield substantially longer accounts and a higher proportion of accurate detail than closed or forced-choice formats. They allow the witness to retrieve information through their own associations, in their own words, and in the order most natural to their memory of the event. They also reduce the risk of contamination, because the interviewer is not introducing new information into the conversation.

Open-ended questioning is the foundation of the Cognitive Interview, the Enhanced Cognitive Interview, the PEACE Model, the NICHD Protocol for child witnesses, and most other research-based interview frameworks. Modern training emphasizes drafting open-ended prompts in advance, using them as the default question form, and reserving closed questions for narrowly targeted clarification once free recall is exhausted.

Particularity

Particularity is the Fourth Amendment requirement that a warrant describe with specificity both the place to be searched and the items to be seized, so the search cannot become the general rummaging the framers feared. A warrant authorizing seizure of broad categories such as ‘documents’ or ‘electronic devices’ untethered to the offense is overbroad.

Particularity is a frequent basis for suppression even where probable cause was strong, because boilerplate and catch-all language invite challenge. The remedy for an overbroad warrant can be suppression of what should never have been authorized, and in some cases of everything seized under it.

PEACE Model

The PEACE Model is a non-coercive, ethically grounded interview framework developed in England and Wales in the early 1990s through a collaboration among police practitioners, psychologists, and lawyers. It was introduced as a response to a series of high-profile miscarriages of justice in which confrontational interrogation practices contributed to false confessions and wrongful convictions, and is now embedded in police training across the UK and many Commonwealth jurisdictions.

PEACE is an acronym for the five phases of the interview: Planning and preparation, Engage and explain, Account, clarification and challenge, Closure, and Evaluation. The Account phase typically follows either a Cognitive Interview structure for cooperative witnesses or a Conversation Management structure for resistant or suspect interviews. Across all phases the model emphasizes rapport, open-ended questioning, careful evidence handling, and respect for legal rights.

The PEACE Model is widely cited in academic and policy literature as a leading example of investigative interviewing aligned with current research on memory, communication, and human rights. The 2021 United Nations Méndez Principles articulate similar non-coercive standards at the international level, drawing in part on the PEACE experience.

PEACE gives the interview its ethical structure. Teach To Talk builds the readiness work into Engage and Explain: the account standard is taught, rehearsed with the Pen Standard, and verified through performance before the account begins. The RETURN Sequence carries out Closure. Inside the Compass, PEACE informs the Route, Clarify, and Test directions. ASC draws on its ethical process, account, closure, and review disciplines, but does not claim PEACE or transfer its support to Teach To Talk.

Pen Contrast

The Pen Contrast is a later return to the opening pen demonstration when an otherwise detailed account abruptly compresses or ends as it approaches the incident. The interviewer preserves and summarizes the answer, addresses the change generally, recalls the pen lesson without identifying the precise gap, and offers an appropriate broad retrieval opportunity.

It is an ASC tool of the Compass’s Retrieve direction. The interviewer considers process and access explanations before using the cue, and addresses such problems whenever they arise. Genuine limits are preserved, and the information is evaluated against the wider account and evidence. The cue is never announced in advance and is not a truth test.

Pen Standard

The Pen Standard is the essential pen demonstration in every complete Teach To Talk opening. A personally familiar, disassembled twist pen makes detailed description and the limits of information visible: the person describes the pen using only what they can responsibly say, then watches the interviewer break it into its parts. The person practices source distinctions, uncertainty, correction, and the rule “never create a detail.” The same pen remains available as a later reminder when a material drop in detail warrants the Pen Contrast.

It is a tool of the Compass’s Teach direction, rehearsed on a neutral object so the account standard is practiced and verified before the real account begins. Access to the demonstration is adapted as needed. Neither the demonstration nor the later cue is a credibility measure or a demand to match the interviewer’s amount of detail.

Performance Standard

The Performance Standard is the requirement that Teach To Talk competency be demonstrated through observable behavior and reviewable decisions rather than course attendance, vocabulary, confidence, rank, years of service, admissions, findings, or case outcome.

It uses six competency domains, four levels of performance, evidence from actual or simulated behavior, targeted feedback, remediation, and reassessment. It is not a validated certification or psychometric score.

Probable Cause

Probable cause is the Fourth Amendment standard that supports searches, seizures, and arrests in U.S. criminal procedure. The U.S. Supreme Court has described it as a fair probability, based on the totality of the circumstances, that contraband or evidence of a crime will be found in a particular place, or that a particular person has committed an offense. The leading modern formulation comes from Illinois v. Gates, 462 U.S. 213 (1983), which adopted the totality-of-the-circumstances test for evaluating informant tips and other supporting information.

Probable cause is more than reasonable suspicion, the lower standard articulated in Terry v. Ohio, 392 U.S. 1 (1968), which authorizes brief investigative stops and limited frisks. It is, however, less than the proof-beyond-a-reasonable-doubt standard required for criminal conviction. In a search-warrant context, the magistrate evaluates probable cause within the four corners of the supporting affidavit, looking for specific, articulable facts and reasonable inferences rather than conclusory statements.

For investigative interviewers, the probable-cause standard is significant in two practical respects: it shapes how interview-derived information must be documented to support warrant applications, and it informs the line between a non-custodial encounter and a seizure, which in turn affects Miranda requirements during questioning.

Procedural Justice

Procedural justice is the research finding, associated with Tom Tyler, that people cooperate with authority they perceive as fair. Its four elements are fairness in process, transparency in actions, opportunity to be heard, and impartiality in decision making.

Rapid TEACH

Rapid TEACH is the urgent delivery of the TEACH opening, used when safety, medical need, scene control, or an evidentiary condition limits contact. It identifies role and immediate purpose, establishes no-guessing and source separation, applies minimal correction or pause control, verifies one use, and seeks only the account the moment requires.

If the Pen rehearsal and full performance check are omitted, it is documented as a Teach To Talk-informed rapid version, not a full Teach To Talk opening.

Rapport Continuity

Rapport Continuity is ASC’s organizing term for the continuing-rapport practices taught in the Compass’s Adapt direction: the observable discipline of preserving voice, respect, neutrality, predictability, and accuracy and accountability after the interview becomes difficult.

Rapport is not agreement, friendliness, or avoidance of legitimate challenge. The term is informed by rapport and procedural-justice research; ASC does not claim the underlying principles.

Reactance

Reactance is the psychological response in which pressure to comply produces resistance instead (Brehm). In interviews, pushing a subject hardens their position; autonomy-supportive approaches reduce it.

Readiness Loop

The Readiness Loop is the part of Teach To Talk that teaches, demonstrates, rehearses, observes, repairs, and verifies performance before the interviewer transfers the floor. It works inside the TEACH opening.

Readiness concerns whether the person can apply the communication instructions to the task presented. The interviewer observes an attempt, clarifies or repairs instruction where needed, and decides whether to proceed, adapt, or stop. Readiness does not establish honesty, complete recall, willingness, or general capacity.

Reid Technique

The Reid Technique is a confrontational, accusatory interrogation method introduced by Fred E. Inbau and John E. Reid in their 1962 textbook Criminal Interrogation and Confessions, later co-authored with Joseph P. Buckley and Brian C. Jayne. It is built on a two-stage structure: a non-accusatory Behavior Analysis Interview, intended to identify deceptive subjects through behavioral cues, followed by a nine-step interrogation in which the interviewer confronts a suspect whose guilt the investigator believes is reasonably certain with the alleged facts and uses themes, minimization, and alternative-question tactics to elicit a confession.

The Reid Technique is commonly categorized by critics and researchers as an accusatorial interrogation model. Empirical research on accusatorial interrogation methods has found that such methods can increase the risk of false confessions, particularly when combined with coercive pressure, minimization, maximization, deception, or questioning of vulnerable suspects. Reid & Associates disputes the claim that the properly applied Reid Technique causes false confessions.

ASC teaches a research-informed alternative: rapport-based, non-confrontational investigative interviewing supported by research funded by the FBI’s High-Value Detainee Interrogation Group (HIG), consistent with the UN Méndez Principles on Effective Interviewing (2021), and built on established, research-supported methods such as the Cognitive Interview (Fisher and Geiselman) and Strategic Use of Evidence (Granhag, Hartwig and colleagues).

RETURN Sequence

The RETURN Sequence is ASC’s accuracy close: six moves for returning the account and then closing the process. Reorient, Echo, Take corrections, Unresolved, Road ahead, Note.

It builds on established work: it is Joe’s way of carrying out the Closure stage of the PEACE framework. Within the Teach To Talk method, the account is made correctable before next steps are explained when the conditions permit. It closes the interview whenever the Compass decision is to stop, but a required stop is not delayed to complete a summary, and later contact is offered only where permitted.

Route Map

A Route Map is a planning format widely used by interviewers and investigators; ASC does not claim it. In Teach To Talk it is the planning tool of the Compass’s Route direction. It identifies the objective and safeguards, the topics to develop working inward, the evidence plan, the foreseeable turning points with lawful if-then branches, and the stopping points. It is a plan, not a script: a deliberate structure to return to when a conversation drifts.

Branches are triggered by what the person says, what remains unresolved, and the applicable safeguards. The Route Map never branches on demeanor, a stereotype, or a prediction that the person is lying.

Source-Neutral Questions

Source-neutral questions are open and specific questions about a topic the evidence touches, such as how a credential is ordinarily kept, whether it was working, or whether anyone else had access to it, asked during account development without naming or hinting at any evidentiary source. They let the person account for the topic before learning what the interviewer holds, and they bring alternative explanations to the surface so they can be checked.

Strategic Use of Evidence places questions of this kind before disclosure; in Teach To Talk they come before the future-tense question of the Disclosure Ladder. The practice is SUE’s; the name is a book-use term. An answer to a source-neutral question is not a deception cue.

Staleness

Staleness refers to the decay of probable cause over time. Information that once established a fair probability that evidence would be found in a place can become too old to support a search, because the evidence may no longer be there. There is no fixed expiration date; whether information is stale depends on the nature of the crime, the character of the evidence, and the passage of time.

Ongoing criminal enterprises, records that persist, and retained digital data support longer windows; a single isolated transaction supports a much shorter one. Affiants address staleness by stating dates plainly and, where time has passed, articulating why the evidence is likely to still be present.

Standard TEACH

Standard TEACH is the complete TEACH opening for a planned interview under ordinary conditions: full frame, account standard, Pen Standard, reciprocal controls, rehearsal, performance check, readiness decision, and protected first invitation.

It is one of three TEACH delivery modes, with Rapid TEACH and Enhanced TEACH.

Stay, Shift, Stack, Stop

Stay, Shift, Stack, Stop are the four navigation decisions of the Adaptive Strategies Compass, made after every turn:

• Stay when the current direction is still working. Don’t change methods just to look busy.
• Shift when a different direction now fits. Tell the person when the task changes.
• Stack when a second direction supports the first. Name which one leads.
• Stop when authority, safety, fatigue, vulnerability, fairness, or information quality requires it. Stopping is a navigation decision, not a defeat. When you stop, close with the RETURN Sequence.

Strategic Use of Evidence (SUE)

The Strategic Use of Evidence (SUE) framework is a research-based approach to evidence disclosure during interviews, developed primarily by Pär Anders Granhag, Maria Hartwig, and colleagues at the University of Gothenburg and John Jay College of Criminal Justice. The framework grew out of a program of experimental research, beginning in the early 2000s, on how the timing and framing of evidence affect a suspect’s verbal behavior.

The core insight of SUE is that suspects who have something to hide commonly attempt to align their statements with what they believe the interviewer already knows. By eliciting a free narrative and specific commitments before disclosing evidence, rather than confronting the suspect with the evidence at the outset, the interviewer creates conditions under which inconsistencies between the statement and the known facts become diagnostic. Strategic, well-sequenced disclosure also tends to elicit additional information, as the suspect adjusts their account in response to each disclosed item.

SUE has been studied in the context of suspect interviews, intelligence interviews, and security screening. Empirical work in controlled studies generally finds that trained SUE interviewers detect deception more accurately than untrained interviewers, and that late disclosure of evidence supports more accurate judgments than early disclosure, while remaining within ethical, non-coercive boundaries. In both the research and ASC’s teaching, the test is the account against the evidence, not the person’s demeanor. SUE research does not make every inconsistency a deception cue, does not validate ASC’s Disclosure Ladder, and does not automatically transfer across roles or sectors.

ASC teaches SUE as a credited tool in the Compass’s Test direction, where it governs the evidence plan. ASC introduces evidence through the Disclosure Ladder and never bluffs, exaggerates evidence, or reads behavior as a verdict.

TEACH

TEACH is the five-function opening of Teach To Talk: Tell the frame, Explain the account standard, Apply it neutrally, Create reciprocal control, Hand over after verification. These five functions organize the guided introduction, including the essential pen demonstration (the Pen Standard) and an applied check of understanding.

It is the core tool of the Compass’s Teach direction. Understanding is checked by performance through the Readiness Loop, not by asking “Do you understand?”, and only the rule that did not land is re-taught. TEACH is delivered in three modes: Standard TEACH, Rapid TEACH, and Enhanced TEACH.

The account standard includes the four sources of an account: what the person experienced, what they worked out, what they learned later, and what they cannot place. The four sources build on established work: they are Joe’s plain-language version of source-monitoring research, including the framework described by Johnson, Hashtroudi, and Lindsay (1993).

Teach To Talk

Teach To Talk is the practitioner-developed, research-informed interviewing method first developed and named by Joseph R. Auriemma, Jr., in 2016 while serving with the New York State Police. It is built on one idea: before you ask a person for an important account, teach them how the conversation works, and teach the interviewer how to protect what they say. One standard for victims, witnesses, and suspects.

It teaches and verifies how to provide a source-bounded account before substantive elicitation, through the TEACH opening and the Readiness Loop. After the interviewer transfers the floor, its communication commitments remain active through development, examination, and return of the account.

The method includes TEACH, the Pen Standard, the Pen Contrast, the protected first account, and the RETURN Sequence. The Adaptive Strategies Compass is its navigation framework. Established, research-supported methods, including the Cognitive Interview (Fisher & Geiselman) and Strategic Use of Evidence (Granhag, Hartwig & colleagues), run on the Teach To Talk standard and remain credited to their originators. Teach To Talk is not a truth test, rapport routine, memory-capacity test, or substitute for law and safeguards, and it has not been independently validated as an integrated method.

Title IX

Title IX is the federal civil-rights statute that prohibits sex-based discrimination in education programs and activities receiving federal financial assistance. Enacted as part of the Education Amendments of 1972 and codified at 20 U.S.C. § 1681 et seq., it applies to virtually all U.S. public school districts and to the substantial majority of colleges and universities.

Although Title IX is most often associated with athletics, its scope extends to admissions, employment, and the response to sex-based harassment, sexual assault, dating violence, and stalking. Implementing regulations issued by the U.S. Department of Education set out specific procedural requirements, which were substantively revised in 2020 (a 2024 revision was vacated by a federal court in January 2025), including obligations to investigate complaints, provide a fair process to both complainants and respondents, and avoid conflicts of interest among investigators and decision-makers.

From an investigative-interviewing perspective, Title IX investigations involve interviews with parties and witnesses under conditions that often include trauma exposure, ongoing relationships among the participants, and significant educational and professional consequences. Effective Title IX interviewing draws on trauma-informed practice, neutral fact-finding, careful documentation, and rigorous separation of investigation from adjudication and from advocacy roles.

Trauma Informed Interviewing

Trauma-informed interviewing is an interviewing practice informed by research on stress, trauma, and memory. Stress and trauma can impair attention, encoding, and recall, and can leave an account fragmented or out of order. Inconsistency is not by itself a sign of dishonesty, or of truthfulness; it is something to clarify, not a conclusion.

Trauma-informed practice is informed by frameworks such as the U.S. Substance Abuse and Mental Health Services Administration’s six key principles of a trauma-informed approach (safety; trustworthiness and transparency; peer support; collaboration and mutuality; empowerment, voice, and choice; and cultural, historical, and gender issues), and by the Forensic Experiential Trauma Interview (FETI) developed by Russell Strand. Common features include preparing the interviewee, offering meaningful choice in pacing and setting, using sensory-oriented prompts where they help, and avoiding repeated demands for chronological reconstruction.

In settings such as Title IX and DASA matters, sexual-assault and domestic-violence cases, child-abuse forensic interviews, and military and intelligence applications, trauma-informed interviewing supports both the well-being of the interviewee and the evidentiary quality of the resulting account. Importantly, trauma-informed practice is not a credibility determination; it is a methodology for gathering reliable information without inflicting unnecessary harm.

Two-Chance Boundary

The two-chance boundary is the interview-conduct boundary for observable disruptive conduct, not disagreement with information. Its four parts, describe the behavior, explain its effect, state the action required, and state the likely consequence, are adapted from Sharon Anthony Bower and Gordon H. Bower’s DESC assertion script.

The first correction describes, explains, and states the required change. The second adds the consequence of another occurrence. If the conduct recurs, the consequence is carried out, unless new information about understanding, access, capacity, or interviewer error requires reassessment. ASC does not claim DESC, and neither the boundary nor its progression is independently validated.

Voluntary Statement

A voluntary statement is a statement freely given by an individual without coercion, in circumstances that do not amount to custodial interrogation. Because the Miranda safeguards attach only when both custody and interrogation are present, statements made outside that context generally do not require a Miranda advisement, although their admissibility may still be tested under the Due Process voluntariness standard.

Whether a statement is voluntary in the constitutional sense is determined by the totality of the circumstances. Courts consider factors such as the length and conditions of the encounter, the use or threat of physical force, deprivation of food, sleep, or contact with the outside world, the use of deception, the suspect’s age, intelligence, mental health, and prior experience with the system, and whether explicit promises or threats were made. The classic articulation appears in Schneckloth v. Bustamonte, 412 U.S. 218 (1973), and related decisions.

For interviewers, the operative point is that even when Miranda does not formally apply, for example, in non-custodial interviews of witnesses or cooperating subjects, statements obtained through coercion, threats, or extreme psychological pressure may still be excluded as involuntary. Documenting the conditions of the interview, the freedom of the interviewee to leave, and the absence of coercive tactics is therefore important whether or not Miranda warnings were given.

“Which Way?” Check

The “Which way?” check is the signature tool of the Adaptive Strategies Compass. The moment the interview starts to struggle, the interviewer pauses and runs eight quick questions in priority order. The first one that fits usually points to the direction to turn. If several fit, the earliest leads and the others can support it.

1. Is the person unsure of the task? Teach
2. Have I taken over their account? Listen
3. Have they reached a memory limit, or could another route help? Retrieve
4. Am I unsure what they mean, how they know it, or whether two statements really conflict? Clarify
5. Is it how I’m communicating? Adapt
6. Can they answer, but won’t? Re-engage
7. Does a settled, understood account conflict with the evidence? Test
8. Have I lost my direction? Route

The first five questions check the problems the interviewer can fix. Only after those have been checked, and addressed where possible, does the interviewer consider that the person may be unwilling, and only an account that is understood is tested against the evidence. If more than one fits, the earliest question leads. The order sets priorities for checking; it is not a set of gates, and the directions themselves have no fixed order. Check yourself before you conclude they’re unwilling.
