COGNITIVE INTERVIEWING By Margo Bennett, M.Ed. and John E. Hess, M.Ed. Special Agents and Instructors FBI Academy Quantico, Virginia When interviewing crime victims, few investigators begin with questions such as: How tall was the subject? What color was his hair? Did he have any scars? Common sense, experience, and fundamental training lead investigators to the conclusion that such specific questions give witnesses little opportunity to tell what they know. Instead, open-ended questions tend to produce the best results. A question like, "What did he look like?" eliminates the need for investigators to anticipate every detail of description victims may have noted. Investigators can always follow up the witness' statements with specific, direct questions to fill in gaps. At least, that is what many interview textbooks suggest. But what happens when even these direct questions fail to produce the details needed from witnesses? The cognitive interview method is a proven technique, effective because it provides interviewers with a structured approach to help retrieve such details from the memories of witnesses. Consider the following scenario: At a robbery scene, a uniformed officer briefs the investigating detective. Hoping to obtain additional information, the detective approaches the clerk, introduces himself, and sensing her anxiety, takes some time to assure her that she has nothing to worry about. He tells her he understands the trauma she has just undergone, gets her a cup of coffee, and delays asking any questions until she has regained her composure. He then tells her that he needs her help and asks that she start at the beginning and tell him exactly what happened. She replies: "I was behind the counter when all of a sudden, I heard a voice telling me to give him all the money, and I would not get hurt. I looked up and saw a man wearing a ski mask pointing a gun right at me. I just froze and stared at the gun. He told me to get a move on or there would be trouble. I opened the cash register and handed him all of the bills. There was just under a hundred dollars in the register. He then told me to lie on the floor and not move. I did as he told me and waited until I was sure he was gone. I yelled to Joe, the manager, who was in the office, who asked me if I was okay. He then ran to the phone and called the police. The next thing I knew, the police officer arrived, and I told him the same thing I just told you. I don't know what the guy looked like, where he came from, or how he got away. I'm sorry I can't be more help." The detective tells her that she has been very helpful and that now he would like to go over the story again, and this time, if she doesn't mind, he will interrupt her with questions as she goes along. As she retells her story, he constantly probes for additional details, such as the possibility of additional witnesses, more descriptive data regarding the subject and his weapon, words he may have used, noticeable accent, and the means of his escape. However, except for a bit more descriptive data, the victim was correct; she had told the responding officer everything she could remember. THE PROBLEM: INABILITY TO REMEMBER The above scenario illustrates a problem encountered by many investigators. That problem results not from investigators being unable to ask good questions but simply from witnesses who are unable to provide the answers. Responses such as, "I don't remember," "That's all I saw," or "I can't recall" frustrate many interviewers on a regular basis. In the past, this led investigators to try hypnosis as a means of enhancing witness recall. Improved results verified what many investigators suspected--an inability of witnesses to remember, not a lack of observations, was the main problem. (1) Although investigators achieved some success through hypnosis, those successes did not last long. Courts, on a regular basis, began ruling in favor of defense attorneys who alleged that hypnotically elicited information may contain flaws and that hypnosis as a means of refreshing recall lacks scientific acceptance. (2) Therefore, investigators now primarily reserve hypnosis for situations where the need for lead information supersedes all other considerations. They know full well that using hypnosis will probably disqualify a witness from testifying. SOLVING THE PROBLEM: THE COGNITIVE INTERVIEW To enhance witness recall without the stigma attached to hypnosis, Ronald P. Fisher and Edward Geiselman, professors at Florida International University and UCLA respectively, have developed a system they call the cognitive interview. Although their process contains few, if any, new ideas, they have systematized some techniques which have, for the most part, been used by investigators only in a sporadic, piecemeal fashion. Research indicates that the cognitive approach to interviewing witnesses increases the quantity of information obtained (3) and does not jeopardize the witness' credibility in court, as hypnosis does. This article compares the traditional interview with the cognitive interview. Specifically, this article deals with the cognitive interview technique as it assists witness memory retrieval by: 1) Reinstating the context of the event, 2) recalling the event in a different sequence, and 3) looking at the event from different perspectives. It also deals with specific retrieval techniques and time factors that affect the interview. Reinstate the Context Traditional interviews of victims and witnesses, similar to the one described above, usually begin with interviewers first taking the time to make introductions and putting witnesses at ease before asking, "What happened?" or "What can you tell me about...?" Then, specific questions follow that are geared to fill in the gaps inadvertently left by witnesses. Proponents of the cognitive interview suggest this will not usually produce optimum results. Asking people to isolate an event in their minds and then to verbalize that event requires them to operate in a vacuum. Even without the trauma that often results from involvement in a crime, common sense says that human memory functions better in context. The cognitive interview process takes this into account. What is meant by context and how do interviewers establish it? Simply put, interviewers make efforts to reestablish the environment, mood, setting, and experiences by asking witnesses to relive mentally the events prior to, during, and after the crime. Let's return to the robbery scene described above with the detective who had already introduced himself to the victim and asked for her help. Instead of asking her what happened during the crime, using the cognitive interview approach, he proceeds as follows: "It's only about 10:00, and it's already been a pretty full day for you. How about telling me how your day started. Tell me what time you got up, the chores you did, the errands you ran and anything else that happened before you came to work." As she recounts her activities, he joins the conversation, discussing events with her, including the problems of a working mother, what she fixed for breakfast, and any other details that she mentions. Only when they have developed a clear picture of those events does the detective next suggest that the victim describe her travel to work. He handles this portion of the conversation in the same way. He does not ask perfunctory questions geared to getting her quickly to the crime scene, but rather, he discusses her commute to work in depth. They discuss the route she took, weather and traffic conditions she encountered, events she may have noticed, and finally, where she parked her car and what she noticed at that time. He wants her not only to just describe her day in general but also to relive it. He uses the same interview technique regarding her arrival at work. By the time they finally get to the discussion of the robbery, they have put the event into context. In many instances, this process enhances measurably a person's retrieval of stored information. Thus, witnesses can see details of the robbery in their proper sequence and context. Concentration is more focused than during any previous interviews, which may have only consisted of isolated questions and answers. The response, "I can't remember," will occur less frequently. Change Sequence To continue the interview and further develop the witness' recall, another phase of the cognitive interview follows next in sequence. Initially, retrieving information from witnesses occurs in a normal, chronological flow of events. However, when recounting from memory, people tend to edit as memory playback occurs. This results in a summary based upon what witnesses regard as important. Therefore, interviewers should address this problem by prompting witnesses not to hold back even the most insignificant detail. Even so, most interviewers can cite experiences where valuable information went unmentioned because witnesses chose to omit it. By changing the sequence of recall, witnesses can look at each stage of the event as a separate entity much akin to looking at individual frames from a film. Reverse or out-of-order recall also encourages an overly zealous witness to stick to the facts. Witnesses find it more difficult to embellish the event when they separate themselves from the natural flow of events and independently deal with each activity. Returning to the eye-witness interview in the opening scenario, the detective might continue using the cognitive interview technique. Accordingly, he would discuss the conversation the victim had with the responding officer and ask where she was when the officer arrived. He wants to know exactly what she was doing at that time. What did she do immediately before that? Through this line of questioning, he gradually arrives back at the time of the robbery and before hand. Thus, he leads her through a second recounting of the crime, only in reverse sequence. This time, her information is a collection of pieces, each viewed independently. Just as looking at a portion of the landscape may reveal details missed while taking in the panoramic view, looking at stages of an event may enable witnesses to "see" previously unnoticed items. Change Perspective To further stimulate witness memory recovery, Fisher and Geiselman also suggest changing the perspective. (4) Witnesses experience an event one time; however, they may perceive it from various views. During initial recollection, witnesses articulate from their personal perspectives and rarely vary from their point of view. By prompting witnesses to physically change the positioning in their memories, interviewers give them the opportunity to recall more of their experiences. (5) Interviewers can change perspective by asking witnesses to consider the view of another witness, victim, or an invisible eye on the wall. Using the technique of changing the perspective of witnesses, the detective in the opening scenario might say: "You know those surveillance cameras they have in banks and some stores? Too bad there wasn't one on the wall over there. I wonder just what it would have recorded; it certainly would have had a different vantage point than you did." Through this opening statement, he can draw the victim into a discussion of what might have been recorded on the nonexistent camera. This technique not only provides her with an opportunity to "replay" the event from a different perspective but it also serves to further detraumatize the situation. Reviewing a film is much less traumatic than reliving an armed robbery. SPECIFIC RETRIEVAL Interviewers can use additional techniques to promote memory retrieval, depending on the facts of the crime and witness information. After witnesses have recounted an event in its natural sequence, reverse sequence, and from different perspectives, the interviewer can induce specific retrieval by asking direct questions. One technique of specific retrieval includes associating witness recollection of physical appearance, clothing, and sound with something or someone familiar to them. Other areas of recall, such as remembering names and numbers, may be enhanced by dealing with individual components of the item, such as the first letter or number. Once established, interviewers direct concentration to the next letter or number and build the response. Using this technique, the detective in the robbery scenario might have first reviewed the details obtained thus far. At certain points, he might have stopped to ask questions such as: "You say he had a scary voice. How so? Does it remind you of anybody you know, or perhaps somebody you've seen in a movie?" "The coveralls he was wearing--ever seen that type before? Where? Were they like a pilot's suit, or more like a carpenter's?" This context-enhancing technique stems from realizing that the victim did not experience this event as a clean slate. She had a lifetime of experiences that preceded this activity. Therefore, when getting a description of the subject, a detective's questions, "Does this person remind you of anyone you know? In what way?" likewise provide a context from which the victim can make comparisons. This removes her need to create, thus enabling her to draw on information with which she is comfortable. TIME FACTORS The cognitive interview encourages a witness' in-depth retrieval of memory. Success with this technique, although a time-consuming process, forces interviewers to avoid some traps normally associated with police interviews, specifically, rushing the recall of witnesses and interrupting their narratives. Witnesses must feel confident that they have time to think, speak, reflect, and speak again as often as they need. Interviewers can instill this confidence by allowing sufficient time for the interview and by refraining from interrupting witnesses. (6) All too often, interviewers say, "Tell me what happened," but before witnesses speak for 30 seconds, interviewers begin interrupting with specific questions. Those specific questions should be asked after witnesses have had the opportunity to recount the event fully. Allowing time to respond also applies when witnesses answer specific retrieval questions. Rushing witnesses sends a message to them that their information is trivial. This results in witness retrieval shutdown. If interviewers don't give them the time, witnesses cannot concentrate or remember. The cognitive interview technique not only enhances witness recall but also addresses another common problem among interviewers--their inability to sustain the interview. Interviewers, particularly inexperienced ones, are often reduced to saying, "I can't think of anything else to ask. Is there anything you're leaving out?" If a witness responds in the negative, the interview is over. Using the cognitive technique can help interviewers avoid prematurely reaching this point. Experience demonstrates that the cognitive interview technique allows interviewers to continue discussing events without sounding redundant. Indeed, continued conversation in a constructive, helpful direction often prompts additional information. CONCLUSION Despite significant advances in various forensic fields, most crimes are solved by information furnished by people. The interview remains the foremost investigative tool for gaining information. Although most victims and witnesses try to cooperate, their inability to recall vital details can be discouraging, and they need help in remembering. This help must come from investigators. Merely asking the right questions does not suffice; enhancing someone's memory requires active involvement. The cognitive approach to interviewing has proven more effective than the traditional one by increasing the quality and quantity of information obtained from witnesses and victims.
