1What is an investigative interview?
A structured, lawful conversation intended to obtain accurate and relevant information from a person who may know facts about an incident.
2What is the primary objective of interviewing a witness?
To obtain a complete, accurate, and independently reported account of relevant observations and experiences.
3What is the difference between an investigative interview and an interrogation?
An interview generally seeks information through nonaccusatory questioning; interrogation commonly focuses on questioning a suspected offender, subject to applicable legal safeguards.
4What is rapport building in investigative interviewing?
Establishing respectful communication and sufficient trust to encourage accurate and voluntary information sharing.
5What is an open-ended question?
A question inviting a person to provide information in their own words rather than selecting from a limited set of answers.
6What is a closed-ended question?
A question seeking a specific or limited response, such as a date, location, number, or yes-or-no answer.
7What is a leading question?
A question that suggests or implies the answer the interviewer expects.
8Why should investigators avoid unnecessarily leading questions during initial witness interviews?
They may influence a witness's account and introduce information that the witness did not independently remember.
9What is a probing question in investigative interviewing?
A follow-up question seeking clarification, elaboration, or additional detail about information already provided.
10What is a funnel questioning technique?
Beginning with broad questions and progressively narrowing to more specific questions as the account develops.
11What is active listening during an investigative interview?
Carefully attending to the person's statements, clarifying uncertainties, and avoiding premature assumptions or interruptions.
12What is cognitive interviewing?
An evidence-informed interviewing approach using memory-retrieval techniques to help witnesses recall information without unnecessary suggestion.
13What is context reinstatement in cognitive interviewing?
Encouraging a witness to mentally recall relevant environmental, sensory, and personal circumstances surrounding an event.
14What is free recall in witness interviewing?
Allowing a witness to describe remembered events in their own sequence and words before detailed questioning.
15What is the purpose of separating witnesses before interviews when practicable?
To reduce opportunities for accounts to be influenced by discussion, shared assumptions, or information from other witnesses.
16What is witness memory contamination?
The alteration or distortion of a person's recollection through exposure to misleading information, suggestion, or other influences.
17What is the misinformation effect?
A memory phenomenon in which misleading information encountered after an event affects later recollection of that event.
18What is source-monitoring error?
A mistake in identifying where remembered information originated, such as confusing personal observation with something heard later.
19Why does witness confidence not always establish identification accuracy?
Confidence may be influenced by feedback, suggestion, and other factors and does not independently prove that an identification is correct.
20What is the purpose of documenting a witness's exact words when material?
To preserve the person's original phrasing and reduce the risk that an investigator's interpretation replaces the actual statement.
21What is the difference between a verbatim transcript and an interview summary?
A verbatim transcript records spoken words as closely as possible; a summary condenses the interviewer's account of relevant information.
22What is the purpose of recording the time, place, and participants of an interview?
To establish the interview's circumstances and support later review, verification, and accountability.
23What is the purpose of documenting breaks during a lengthy interview?
To preserve an accurate record of interview conditions, timing, and any interruptions affecting the process.
24What is the purpose of asking a witness to distinguish personal observations from information received from others?
To identify the source of each statement and assess its evidentiary significance and reliability.
25What is the difference between a witness's observation and interpretation?
An observation describes what the witness directly perceived; an interpretation expresses what the witness believes those perceptions mean.
26What is the purpose of an interview closure?
To clarify important details, allow additional information, explain appropriate next steps, and document the interview's conclusion.
27What is a witness recantation?
A later withdrawal or material retraction of an earlier statement or allegation.
28How should an investigator respond to a witness who materially changes an earlier account?
Document the changes accurately, examine possible explanations, and seek independent corroboration without assuming either account is necessarily truthful.
29What is corroboration in criminal investigation?
Independent evidence or information that supports a material part of another account or investigative proposition.
30What is the purpose of a witness credibility assessment?
To evaluate the reliability of relevant statements using perception, opportunity to observe, consistency, possible influences, and independent evidence.
