Examining the cognitive interview in a double-test paradigm

Abstract

The Cognitive Interview (CI) was compared with a standard interview protocol (based on the National Transportation Safety Board) to interview witnesses of a videotaped traffic accident. Witnesses were tested twice, five minutes after viewing the accident and again two weeks later. The CI elicited approximately 70% more correct facts than did the standard interview, and at equivalent accuracy rates, at both the first interview and the second interview. The double-testing procedure generated novel data patterns that may allow us to identify incorrect recollections; other results lead us to question some legal assumptions about the diagnosticity of inconsistent recollections.     

The cognitive interview: Much more than simply “try again”

Abstract

In the legal context, the elicitation of complete and accurate statements from witnesses and victims is essential. The Cognitive Interview (CI) was devised to improve eyewitnesses' memory by using mnemonic strategies which ask witnesses to think about what happened and encourage them to make as many retrieval attempts as possible. However, no known study has experimentally examined whether (or not) the CI superiority effect is something more than merely asking a witness to retrieve information four times. The aim of this study was to compare the recall obtained by means of the CI - in which mnemonics are used - to that obtained as a result of asking subjects to make a multiple free recall task - without using mnemonics - in a single interview session. It was expected that significant differences would still exist. Results confirmed this hypothesis.     

The Cognitive Interview: novice police officers' witness/victim interviewing practices

Abstract

The objective of this study was to investigate novice police officers’ witness interview practices immediately post investigative interview training (known as PEACE) with reference to the eight Cognitive Interview (CI) components taught. Forty-eight UK police officers took part as interviewers. Forty-eight undergraduates participated as mock witness; they viewed a non-violent crime video and 2 days later were individually interviewed by a police officer. Interviews were recorded and rated for officers’ application of the CI procedure.

Despite having recently completed the only training available to them no officer applied or attempted to apply the CI procedure in its entirety. However, some of the individual CI components were applied more frequently than others. This study provides a unique insight into the interviewing practices of some of the least researched, least experienced, and least trained investigative interviewers who, nonetheless, conduct witness interviews on a daily basis. The emergent picture suggests that either the CI procedure currently taught to novice police officers is too complex at so early a stage in their police career and/or that the current training may be insufficient to equip them with the skills necessary to effectively apply the procedure.     

Comparative analysis of true or false statements with the source monitoring model and the cognitive interview: special features of the false accusation of innocent people

Abstract

We describe two experiments designed to verify whether the source monitoring (SM) model categories and the cognitive interview (CI) contribute to distinguishing true from false statements. We used a 2 Type of Interview (Structured/Cognitive) × 2 Statement Condition (True/False) design with 18 interviewers in a sample group of 240 gender-matched university students being interviewed about a film fragment. In Experiment 1, participants who lied exculpated the protagonist from rape, whereas in Experiment 2 their lies were aimed at accusing an innocent person. As dependent variables we used criteria from the SM: details, supporting memories, thoughts and feelings and cognitive operations. The results suggest that the statements of honest participants interviewed using the CI provided more overall information than those obtained under any other condition. When a lie is aimed at exculpating someone from criminal behaviour, statements involve more cognitive operations and less sensory, temporal and contextual information, but only when the structured interview (SI) is used. When the lie is aimed at falsely accusing someone, the SI and the CI produce similar results. We discuss the forensic importance of these findings.     

THE COGNITIVE INTERVIEW AND ITS EFFECT ON WITNESSES’ CONFIDENCE

Today there is ample evidence that the Cognitive Interview (CI) enhances witnesses’ memory. However, less is known about how the CI affects eyewitnesses’ confidence. To address this shortcoming we conducted a study analyzing how realism in confidence was affected by the CI. All participants (n=79) were first shown a filmed kidnapping. After 2 weeks we interviewed one-third of the participants according to the guidelines of the CI, one-third according to a Standard Interview (SI), and one-third were not interviewed at all (Control condition). Participants in all three conditions were then asked to answer 45 forced-choice questions, and to give a confidence judgment after each choice. For the 45 questions, no differences in accuracy were found between the three conditions. Confidence was higher in the CI and SI conditions, compared with the Control condition. CI and SI did not differ in metacognitive realism but both showed lower realism compared with the Control condition, although only CI significantly so. The results indicate that the inflation in confidence is more likely to be explained in terms of a reiteration effect, than as a consequence of the particular mnemonics characterizing the CI (e.g. “mental reinstatement of context”). In sum, CI does not seem to impair (or improve) the realism in witnesses’ confidence, and does not inflate confidence in erroneous recall, compared to a SI.     

From laboratory to the street: Capturing witness memory using the Self‐Administered Interview

The Self‐Administered Interview (SAI^©) is a tool designed to elicit a comprehensive initial account from witnesses at the scene of an incident or shortly thereafter to inoculate against the loss of information associated with delayed interview. Drawing on the principles of the Cognitive Interview (CI), the SAI^© provides witnesses with a series of instructions and retrieval cues to support recall. Requesting that witnesses complete an SAI^© not only serves to preserve and protect memory but also enables officers to prioritize the allocation of policing resources during the critical early stages of an investigation. The current review traces the development of the SAI^© from a series of laboratory studies through to field trials and integrates our findings with theoretical accounts of human memory. We present new data from trials of the tool in the field and consider future avenues for research and further development of the SAI^©.     

Modifying the cognitive interview: countenancing forensic application by enhancing practicability

The UK investigative interview model advocates police officers use the cognitive interview (CI). However, research has indicated that many officers perceive the CI as too cumbersome, complex, and time consuming for some types of crime. With this in mind we investigate the efficacy of two CI procedures, which have been substantially modified to enhance forensic practicability and retain the empirically demonstrated CI superiority effect. Employing the mock witness paradigm, both are compared to the procedure currently taught to UK police officers. Participant's memorial performance revealed no differences across interview conditions for the amount of correct and incorrect recall. However, those interviewed using the modified procedures confabulated less and were more accurate. Considering type of information recalled (person, action, object, and surrounding), no differences were found across conditions for correct or confabulated type recall. However, the two modified CIs elicited fewer incorrect person and object information items. Further, they were shorter in duration than the current procedure. Hence, for frontline less serious crime, or in time critical situations, the modified procedures may be viable alternatives. These findings and their implications are discussed.     

The Self-Administered Interview: a means of improving children's eyewitness performance?

Abstract

In order to obtain the most informative and correct statements, witnesses should be heard as soon as possible after the incident. However, this is not always possible. This experimental study investigated whether completing a Self-Administered Interview form (SAI) immediately after a critical event could enhance children's witness performance at a later stage. Children (N = 194, age 11–12) reported their memory of an event in a structured SAI, an open SAI, or did not report their memory (control). Two weeks later, the children were interviewed about the event. Before the interview, half of the children were subjected to social influence from a co-witness. Children's free recall of the event was enhanced by the SAI. More precisely, children in the SAI-Structured condition reported more details about the event than children in the SAI-Open condition and the control condition, without a loss of accuracy. The SAI manipulation did not, however, reduce children's vulnerability to social influence. The results suggest that the use of a SAI might prove a simple and yet effective way of increasing the quality of statements from child witnesses in some situations.     

Recall of unpleasant emotion using memory-enhancing principles

Abstract

Two experiments are presented to examine the issue of memory for past emotions. Participants rated their emotional reactions on the occasion of watching a film, and in a subsequent session, they were asked to recall and rate the emotion as experienced when viewing it. In the first experiment, participants underestimated unpleasant emotion at recall, but their recall was improved with the presentation of a visual cue pertaining to the emotion-inducing film event. In the second experiment, participants were assisted in probing perceptual aspects of the event by means of memory-enhancing instructions underlying the Cognitive Interview. These participants consistently recalled emotional intensity, as compared to participants in the unassisted recall condition who underestimated prior emotion. This research suggests that ratings of prior emotion are easily influenced by features of the retrieval context, and that consistent recall may be achieved by memory-enhancing principles of the Cognitive Interview.     

Differential effectiveness of the cognitive interview in a simulation of testimony

The cognitive interview (CI) is a set of forensic evaluation procedures that has proven its efficiency. Nevertheless, little investigation has been made into its usage on witnesses with the intention of lying. With the aim of proving whether the efficiency of the CI is maintained where the witness is lying we carried out two experiments and we included instructions to tell the truth or to lie as independent variables. We used a 2 Type of interview (SI/CI)×2 Statement Condition (True/False)×2 Interviewee Gender (Male/Female) design with 18 interviewers in a sample group of 240 gender-matched university students being interviewed and the classic measures from the CI as dependent variables: the total number of details, details of actions, details about people and details concerning objects. In a first experiment, participants who lied exculpated the protagonist of a film fragment from rape, whereas in a second, those who lied accused an innocent protagonist. The results, in accordance with previous studies, showed a globally better efficiency for CI. Nevertheless, analysing the material based on type of details, this efficiency is only found in details concerning actions and objects. We discuss the forensic importance of these findings.     

Are jurors' perceptions of eyewitness credibility affected by the cognitive interview?

Abstract

Ninety-one college subjects listened to Cognitive Interviews (CI) and Standard police interviews of 7-year old children who were attempting to describe an earlier incident of playing a game of Simon Says. The subjects evaluated the witness's credibility and also the interviewer's manipulativeness. The perceived credibility of the witness was not affected by the type of interview, i.e., the CI did not render the witness unduly credible. In addition, the CI interviewer was judged to be less manipulative than the Standard police interviewer. These results were discussed in light of some potential legal concerns about using the CI.     

The prevalence of violence and relation to depression and illicit drug use among incarcerated women in Recife, Brazil

PurposeTo assess the prevalence and different types of violence experienced by women prisoners in Brazil and the effects of violence on women's depression and illicit drug use.MethodsParticipants (N = 377) were incarcerated women from a state prison in a northeastern city of Brazil. Multivariate logistic regression models (adjusted for age, education, partner status, prison history, drug related offense, and sentencing status) were used to assess associations between each type of violence (physical abuse, sexual abuse, and life threats) and each outcome variable: recent depression and illicit drug use.ResultsThe majority of participants (87%) reported experiencing some type of violence in their lifetime, including physical violence (83%), sexual victimization (36%), and threats on their life (29%.) Sexual violence was significantly related to both recent depression (Odds Ratio (OR) = 2.8; 95% Confidence Interval (CI) = 1.4–5.3) and recent substance use (OR = 2.7; 95% CI = 1.6–4.4) in adjusted models. Experiences of life threats were also significantly associated with illicit drug use (OR = 2.2; 95% CI: 1.3–3.7), as was physical violence (OR = 2.4; 95% CI: 1.2–4.9); however, neither of these latter two violence variables were significantly associated with depression.ConclusionReports of lifetime violence victimization among this incarcerated sample of women were extremely prevalent and relevant to women's depression and illicit drug use. Prison efforts to address women's depression and illicit drug use may be most effective by incorporating aspects related to women's history of victimization, especially given the high rates of violence experienced by women in this sample.     

Application of operational psychology to assessment of inmates

Abstract

The newly developed actuarial risk instruments, Static-2002 (Hanson & Thornton, 2003a) and Risk Matrix 2000 (RM2000) (Thornton et al., 2003), were cross-validated and compared with Static-99 (Hanson & Thornton, 2000) in a retrospective follow-up study of 304 forensic psychiatrically evaluated sexual offenders (mean time-at-risk=14.8 years). All instruments predicted any sexual, non-sexual violent and any violent recidivism moderately for child molesters [area under the curve (AUC) of the receiver operating characteristic (ROC)=0.67 (95% CI=0.57–0.77) to 0.76 (95% CI=0.68–0.85)] but poorly for rapists [AUCs=0.64 (95% CI=0.51–0.70) to 0.68 (95% CI=0.59–0.77)]. The instruments also predicted severe sexual recidivism moderately for child molesters [AUCs=0.74 (95% CI=0.63–0.86) to 0.79 (95% CI=0.70–0.89)] but were of no value in informing on this outcome for rapists [AUCs=0.58 (95% CI=0.47–0.68) to 0.63 (95% CI=0.53–0.73)]. AUC estimates were generally higher for Static-2002 and RM2000 than for Static-99, but no single instrument demonstrated statistical superiority. The study provides support for implementing actuarial instruments in applied risk assessments of child molesters.     

Spaced cognitive interviewing: Facilitating therapeutic and forensic narration of traumatic memories

Abstract

The evolution of the cognitive interview (CI) is reviewed from the original package of memory-enhancing techniques through to the revised (or enhanced) CI, and the cognitive approach now taught to police officers in UK. Many officers are reluctant to apply CI, particularly to traumatised victims. The traumatising effects of crime are examined in terms of immediate response and the potential for an acute stress response and post-traumatic stress disorder, with subsequent re-experiencing of dissociated traumatic memories in the form of intrusive, unwanted imagery. Traumatic memories are described, particularly their accuracy, detail and persistence. The therapeutic potential of prolonged experience of distress while narrating the content of traumatic imagery is explained. An approach to maximising the disclosure of dissociated detail - spaced cognitive interviewing (SCI) - is described and case material presented illustrating its forensic and therapeutic application. The practice and practical implications of SCI are summarised.     

Using the cognitive interview with adults with mild learning disabilities

Abstract

Forty-seven adults with mild learning disabilities (mild intellectual disabilities) attending day-centres and thirty-eight adults from the general population viewed a videorecording of an accident. A day later the participants were interviewed using either a cognitive interview (CI) or a structured interview (SI, a control interview). Compared with their counterparts with learning disabilities, adults from the general population recalled more correct information and made fewer confabulations about persons and objects. Nevertheless, the type of interview had an impact. For both groups, the CI was more effective than the SI in enhancing recall although, for the ‘learning disabilities’ group, the CI also produced a disproportionate increase in the reporting of person confabulations. All the same, the accuracy ratios were similar across interview types (80% for the CI and 82% for the SI). It is suggested that the CI could be helpful in assisting people with learning disabilities to provide information about events they have seen.     

Race,Ethnicity and the Risk of Homicide Victimization in the United States

Abstract

Linked data from the National Health Interview Surveys and Multiple Causes of Death Use Files are used to estimate the individual level effects of race and ethnicity, and relevant controls on homicide mortality. African American and Hispanic race/ethnicity are found to be leading factors in homicide victimization. Following some previous work this research also finds that the gap between white and minority homicide victimization is attenuated but not explained by SES, contextual and marital status variables. It is hypothesized that the experience and perception of racism, and the frustration, anger and resentment that result produce an ideological climate that sustains high levels of violence among minority members beyond what concentration of disadvantage variables predict.
