When interviewing witnesses to a crime, police
interviewers seek to maximize the amount of
information that a cooperating eyewitness can give
them so that they can generate leads to follow, confirm
(5) or disconfirm alibis, and so forth. One method for
eliciting information over and above what a
cooperative witness might otherwise provide is the
cognitive interview.
Developed by psychologists and adopted by
(10) police forces around the world, the cognitive interview
combines cognitive techniques known to improve recall,
such as multiple retrieval attempts, with communication
strategies developed by social psychologists, such as
conversation-management skills and techniques for
(15) building rapport between interviewer and interviewee.
The general consensus is that this package has proven
successful in increasing the number of details recalled
by witnesses, with little impact on the number of
incorrect details reported (neither increasing nor
(20) decreasing overall accuracy). However, a problem
associated with the cognitive interview is that it is a
complex procedure, requiring substantial training to
learn and a long time to conduct. Because of this
complexity, not all officers receive this training, and
(25) even trained officers often deviate from the pro-
cedures specified in the cognitive interview training.
An alternative to the cognitive interview is
hypnosis. Indeed, hypnotic investigative interviewing
was a precursor to the cognitive interview. However,
(30) even though the techniques involved are much less
complex, the evidence suggests that overall accuracy,
as determined by the proportion of correct to incorrect
responses, is not generally improved with hypnosis; in
fact, sometimes it may deteriorate. Hypnosis may also
(35) give rise to a “false confidence” effect, whereby
witnesses are more confident in their reports generally,
including reports of incorrect information. There are
other practical difficulties, most notably that not all
witnesses are susceptible to hypnosis.
(40) For police interviewers, the ideal method for
eliciting additional information from an eyewitness
would be one that requires no special training for the
interviewer, that can be applied to the entire population
of potential witnesses, and that has a positive effect on
(45) correct memory reports, with no corresponding
increase in false details reported. Research suggests
that such a method may in fact be available.
Encouraging eyewitnesses to close their eyes during
recall attempts is a technique that is common to both
(50) hypnosis and the cognitive interview. Recent studies
demonstrate that instructed eye-closure can benefit
recall for both visual and auditory materials, for events
witnessed on video, and for events witnessed through
live interactions. These studies indicate an improvement
(55) over hypnotic interviewing, with no problems of
participant dropout because of lack of hypnotic
susceptibility. More significantly, instructed eye-closure
by itself appears to improve witness recall to a degree
equivalent to that demonstrated by the cognitive interview.
(60) And the benefits of eye-closure are achieved
with no increase in errors, no specialist training, and
no greater complexity of interviewing technique.
1. Which one of the following most accurately expresses "the main point of the passage?(A) For police interviewers, the ideal interview procedure would be one that is simple to apply, universally applicable, and reliably successful at eliciting accurate information.
(B) Interviewing witnesses is a crucial component of law enforcement, but all existing interview procedures require some trade-off between reliability and practicality.
(C) Instructing witnesses to close their eyes during memory-recall tasks is a technique common to both hypnosis and the cognitive interview.
(D) Though difficult to implement on a large scale, the cognitive interview is the most effective procedure police officers can use when questioning an eyewitness.
(E) Instructed eye-closure improves witness recall without sacrificing practicality or reliability, making it an ideal interview technique for police interviewers.
2. According to the passage, each of the following is true of the instructed eye-closure technique EXCEPT:(A) It requires less training than the cognitive interview.
(B) Studies have shown that it can benefit recall for events witnessed on video.
(C) It does not lead to an increase in erroneous memory reports.
(D) It may give rise to a "false confidence" effect.
(E) It is common to both hypnotic interviewing and the cognitive interview.
3. The author refers to "alibis" (first sentence of the passage) primarily in order to(A) highlight a positive contribution made by psychological research
(B) exemplify the kind of information police interviewers seek to elicit from suspects
(C) point to a use to which an effective interview procedure might be put
(D) contrast the concerns of police officers with those of psychologists
(E) illustrate the complexity of the cognitive interview
4. The author would be most likely to agree with which one of the following statements?(A) There is reason to worry that the cognitive interview is less effective if police
interviewers deviate from the procedures specified in the training.
(B) An interviewer's success at eliciting valuable information from a witness derives largely from the interviewer's ability to establish a rapport with the witness.
(C) Though it suffers from significant drawbacks, hypnotic interviewing has an advantage over other investigative interviewing procedures in that its effective use requires essentially no training.
(D) When interviewing witnesses, police interviewers may need to use different techniques depending on whether the desired information is visual or auditory in nature.
(E) An increase in the complexity of an interview procedure will usually result in a decrease in the reliability of the information obtained.
5. It can be inferred from the passage that the use of hypnotic interviewing most likely has which one of the following consequences?
(A) Interviews yield more inaccurate information than accurate information.
(B) Interviewers are overly confident that complex interview procedures have been followed correctly.
(C) Interviewers are not able to detect attempts by a witness to intentionally deceive the interviewer.
(D) Interviewers are not able to accurately assess the reliability of a witness's memory reports by asking the witness how sure he or she is concerning those reports.
(E) Interviewees become less susceptible to hypnosis over the course of the interview process, resulting in a steady decrease in the amount of information they are able to provide.
6. Which one of the following describes a relationship that is most analogous to the one that holds between the cognitive interview and instructed eye-closure, as described in the passage?(A) Studies show that individuals who frequently engage in light exercise enjoy significant health benefits, but equivalent health benefits are enjoyed by those who engage in more strenuous exercise on a less frequent basis.
(B) Reduced consumption of saturated fat combined with an increased consumption of fiber has been shown to produce significant health benefits, but equivalent health benefits have been produced by an increase in fiber consumption alone.
(C) Consumption of moderate amounts of caffeine has been linked to positive health benefits, but excessive caffeine consumption has been shown to elevate blood pressure.
(D) Research has shown that a new vitamin supplement can produce dramatic benefits in women, but data is inconclusive regarding men.
(E) Studies suggest that diet and exercise produce observable health benefits, but less significant benefits can be achieved through exercise alone.
7. The author would be most likely to agree with which one of the following statements?(A) If all witnesses were susceptible to hypnosis, hypnotic interviewing would be the best procedure for maximizing the amount of accurate information obtained from
cooperative witnesses.
(B) Even if police forces had the time and resources to train all of their officers in the cognitive interview, the complexity of the procedure would still pose problems for its use.
(C) Instructed eye-closure should be adopted as an investigative interviewing technique only if police forces lack the resources required to implement the cognitive interview.
(D) Interview procedures that are easy to learn are likely to yield a greater amount of accurate information than interview procedures that are more difficult to learn.
(E) The more information a cooperative witness provides when interviewed, the more likely it is that the witness is experiencing a "false confidence" effect.
