The effect of post‐identification feedback on the recall of crime and perpetrator details

The present study examines the effect of identification feedback on the quantity and accuracy of crime event details recalled, willingness to attempt misleading questions and confidence in the accuracy of these details. All participants (N = 60) viewed a short video clip of a staged building society robbery and then made a false identification of the robber from a target‐absent photospread. Eyewitnesses were next given confirming feedback (i.e. told that they had identified the suspect), disconfirming feedback (i.e. told that they had failed to identify the suspect) or no feedback. All eyewitnesses then attempted a series of short‐answer questions relating to details about the robber, accomplice, victim, building society, theft and getaway. Disconfirming feedback significantly reduced eyewitness confidence in recall accuracy but there was no significant effect of feedback on the overall quantity and accuracy of details recalled or willingness to attempt misleading questions. The theoretical implications of these results are discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

Post‐identification feedback effects: Investigators and evaluators

We investigated the effects of post‐identification feedback and viewing conditions on beliefs and interviewing tactics of participant‐investigators, crime reports of participant‐witnesses and participant‐evaluators' credibility judgments of the witnesses. Study 1 participants assumed the roles of witness and investigator (N = 167 pairs). Witnesses' view of a simulated crime video was manipulated by distance from viewing monitor: 2 or 9 ft. Participants made a line‐up identification and received either positive feedback or no feedback. Significant effects for witnesses and investigators were associated with viewing condition and post‐identification feedback. Interviews between investigator‐witness pairs were videotaped. Investigators asked more positive, leading questions when they were led to believe that the witness had identified the suspect. In Study 2 evaluators (N = 302) viewed the witness‐investigator interviews. Viewing condition had no effect on judgments of witness credibility but positive post‐identification feedback led evaluators to judge witnesses as more credible than witnesses who received no feedback.

The effects of post ‐identification feedback and age on retrospective eyewitness memory

Two studies examined the effects of post‐identification feedback, age, and retention interval on participants' memories and beliefs about memories for a videotaped event, as captured by a store surveillance camera. After viewing the video, they were then asked to identify the suspect from a target‐absent photo line‐up. After making their identification, some participants were given information suggesting that their identification was correct, while others were given no information about the accuracy of their identification. In both experiments participants who received confirming feedback indicated they were more confident in their identification, paid more attention to the video, and that they were more willing to testify in court than those who received no feedback. The confidence inflation effects of post‐identification feedback did not vary with retention interval or age. These results are consistent with a position focusing on accessibility, which suggests that witnesses have little or no retrievable recollection of how sure they were at the time of their identification.

‘Good,you identified the suspect…but please ignore this feedback’: can warnings eliminate the effects of post‐identification feedback?

The present experiments focus on whether the post‐identification feedback effect can be reduced by providing participants with warnings. Participants viewed a crime on video and identified a suspect from a target‐absent lineup (Experiment 1) or target‐present lineup (Experiment 2). Participants then received positive feedback, negative feedback or no feedback. Half of the participants received a warning saying their feedback was randomly generated by the computer, and the other half received no warning. Robust post‐identification feedback effects were observed in both experiments in the no warning condition. These effects were largely eliminated when participants received a warning. In Experiments 3 and 4, we failed to find an ameliorative effect of a forensically realistic warning. These results indicate that warnings can reduce the effect of post‐identification feedback in principle, but the application of warnings in practice may be more difficult.

The Moderating Effect of Ecphoric Experience on Post‐identification Feedback: A Critical Test of the Cues‐based Inference Conceptualization

Confidence inflation from confirming post‐identification feedback is greater when the eyewitness is inaccurate than when the eyewitness is accurate, which is evidence that witnesses infer their confidence from feedback only to the extent that their internal cues are weak. But the accurate/inaccurate asymmetry has alternative interpretations. A critical test between these interpretations was conducted by including disconfirming feedback conditions. Student participants (n = 404) witnessed a mock crime, had either a strong or weak ecphoric experience when making their line‐up identifications, and subsequently received no feedback, confirming feedback, or disconfirming feedback. Consistent with a cues‐based conceptualization of the feedback effect, disconfirming feedback influenced witnesses with weak ecphoric experiences more than witnesses with strong ecphoric experiences, ironically increasing the confidence‐accuracy relation.

How elevated blood alcohol concentration level and identification format affect eyewitness memory: A field study

Research shows that alcohol has a small and inconsistent effect on eyewitness recall and no effect on witnesses' lineup decisions. Much of this literature has tested participants with low‐to‐moderate blood alcohol concentration (BAC) levels, and no study has directly examined how identification procedure impacts intoxicated witnesses' decisions. In the present study, bar patrons' (N = 132) BAC levels were recorded before participating in a task. Midway through the task, they were interrupted by an intruder. Participants then recalled the incident via a staged interview and attempted to identify the intruder from a target‐present or target‐absent showup or lineup. Although elevated BAC levels (high as 0.24%) reduced the quantity and quality of information provided, BAC had no effect on witnesses' identification decisions regardless of format. Results highlight the importance of testing witness memory across a broad BAC spectrum and provide evidence that alcohol does not affect witnesses' identification ability.     

Post‐merger identification as a function of pre‐merger identification,relative representation,and pre‐merger status

This experiment examined the impact of pre‐merger identification (low, high), pre‐merger group status (low, high) and relative representation (low, high) upon identification with a new merger group. In the first phase of the study, 156 university students were assigned to a pre‐merger team of ‘inductive’ thinkers. Pre‐merger identification was manipulated by giving the participants feedback about the extent to which they used the inductionist style. Pre‐merger status was manipulated by informing participants that their team had performed worse or better than a deductionist team on a decision‐making task. In the second phase, the two pre‐merger teams were combined into a merger team of analyst thinkers. Relative representation was manipulated by maintaining most or none of the features of the pre‐merger team in this new merger team. The results revealed that high pre‐merger identifiers identified more strongly with the merger group than did low pre‐merger identifiers, but only when the relative representation was high. Pre‐merger status did not influence post‐merger identification. Copyright © 2006 John Wiley & Sons, Ltd.     

Two field studies on the effects of alcohol on eyewitness identification,confidence, and decision times

In two field studies, bar tenants (Ns = 86 and 190, respectively) were successively approached by confederates C1 and C2 on a night out. Confederate C3 then presented participants with a six‐person target‐absent or target‐present lineup concerning C1 or C2 (immediate test). Several days later, participants viewed a lineup regarding the confederate they had not attempted to identify earlier (C1/C2; delayed test). An immediate compared with a delayed, sober identification test did not increase the risk of a false identification decision. A blood alcohol concentration of 0.06–0.07% best discriminated accurate from inaccurate decisions. Choosers with a blood alcohol concentration ≤ 0.06% showed excellent calibration and little overconfidence, and their confidence was a strong indicator of accuracy (i.e., good resolution). Choosers with a higher intoxication level displayed poor calibration and strong overconfidence. Nonchoosers were generally poorly calibrated. Combined analyses showed a negative effect of intoxication on one's ability to discriminate the target from nontargets.     

Memory distortion in eyewitnesses: a meta‐analysis of the post‐identification feedback effect

Feedback administered to eyewitnesses after they make a line‐up identification dramatically distorts a wide range of retrospective judgements (e.g. G. L. Wells & A. L. Bradfield, 1998 Journal of Applied Psychology, 83(3), 360–376.). This paper presents a meta‐analysis of extant research on post‐identification feedback, including 20 experimental tests with over 2400 participant‐witnesses. The effect of confirming feedback (i.e. ‘Good, you identified the suspect’) was robust. Large effect sizes were obtained for most dependent measures, including the key measures of retrospective certainty, view and attention. Smaller effect sizes were obtained for so‐called objective measures (e.g. length of time the culprit was in view) and comparisons between disconfirming feedback and control conditions. This meta‐analysis demonstrates the reliability and robustness of the post‐identification feedback effect. It reinforces recommendations for double‐blind testing, recording of eyewitness reports immediately after an identification is made, and reconsideration by court systems of variables currently recommended for consideration in eyewitness evaluations.

Sex Differences,Weapon Focus,and Eyewitness Reliability

Abstract

Two aspects of eyewitness identification were tested: sex differences in eyewitness reliability and an explanation of the weapon focus effect that is based on object salience. One hundred ninety-one male and female American college students watched a slide sequence that depicted a male or female target person enacting a simple behavioral progression while holding various objects. Afterward, the subjects attempted to identify the target person in a photospread and to recall physical details about him or her on a questionnaire. The results confirmed a predicted own-sex identification bias effect (p < .001) but did not support the object salience hypothesis. An interaction between subject sex and object indicated that men and women attended to and were distracted by different types of objects (p < .009).     

Social Judgment of Abortion: A Black-Sheep Effect in a Catholic Sheepfold

Abstract

French Catholic participants (N = 340) with high or low religious identification read 1 of 8 scenarios presented as an interview with a female target 2 months after she had had an abortion. The experimental device varied situational pressure (pressure vs. no pressure), the target's religious social identity (Catholic vs. neutral), and the consequences of abortion for the target (positive vs. negative). The participants then rated the acceptability of the target's decision. The participants judged abortion more negatively in the no-pressure condition. Moreover, the participants with high religious identification judged abortion more negatively than did those with low religious identification. In partial support of a black-sheep effect, the participants with high religious identification judged the Catholic target more negatively than they judged the neutral one in some conditions (pressure, negative consequences). In other conditions (no pressure, both positive and negative consequences), the participants with low religious identification judged the Catholic target more positively than they judged the neutral one.     

When the physical coldness in the viewer's environment leads to identification with a suffering protagonist

Based on theories of narrative engagement and embodied cognition, we hypothesised that a fit between the psychological state of a protagonist and the physical sensation of the viewer would enhance the subsequent identification with the protagonist, but not para-social relationship with him (seeing the protagonist as a friend). We also hypothesised that identification and a para-social relationship would lead to distinct effects on attitudes related to the narrative. Participants (N = 60) were randomly assigned to either a warmed or cooled room where they watched a movie clip alone in which a suffering protagonist wanted to undergo euthanasia while his close others wanted him to stay alive. Then, the participants answered a questionnaire measuring their identification and para-social relationship with the protagonist and their attitudes toward euthanasia. In accordance with the hypotheses, the results demonstrated that feeling cold enhanced identification with the suffering protagonist. However, the environmental temperature did not affect the development of para-social relationships. Moreover, identification with the suffering protagonist contributed to acceptance of his attitudes, reflected in more positive views of euthanasia. In contrast, having a para-social relationship with the protagonist resulted in negative attitudes toward euthanasia.     

She Looks Sad,But He Looks Mad: The Effects of Age,Gender, and Ambiguity on Emotion Perception

This study investigated how target sex, target age, and expressive ambiguity influence emotion perception. Undergraduate participants (N = 192) watched morphed video clips of eight child and eight adult facial expressions shifting from neutral to either sadness or anger. Participants were asked to stop the video clip when they first saw an emotion appear (perceptual sensitivity) and were asked to identify the emotion that they saw (accuracy). Results indicate that female participants identified sad expressions sooner in female targets than in male targets. Participants were also more accurate identifying angry facial expressions by male children than by female children. Findings are discussed in terms of the effects of ambiguity, gender, and age on the perception of emotional expressions.     

Identifying and changing the normative beliefs about aggression which lead young Muslim adults to join extremist anti‐Semitic groups in Pakistan

Two studies investigated the role of beliefs about the acceptability of aggression (“normative beliefs”) against Jews in determining who would join an extremist group. In Study 1, students in a university in Pakistan (N=144) completed self‐report attitude measures, and were subsequently approached by a confederate who asked whether they wanted to join an extremist anti‐Semitic organization. Normative beliefs about aggression against Jews were very strong predictors of whether participants agreed to join. In Study 2, participants (N=92) were experimentally assigned to either a brief educational intervention, designed to improve inter‐group relations, or to a control group. They also filled in self‐report attitude measures pre and post intervention. Participants in the intervention group were much less likely to agree to join the extremist group, and this effect of the intervention on joining was mediated by changes in normative beliefs about aggression against Jews. The results have implications for theories of inter‐group aggression and interventions to prevent people from being recruited into extremist groups. Aggr.

The effects of adult attachment style on post‐transgression response

Two studies examined the relation between adult attachment styles and post‐transgression responses. Secure participants were predicted to be forgiving, preoccupied participants to be grudge oriented, fearful participants to be avoidant, and dismissing participants to be vengeful. Study 1 was nonexperimental, using a community sample of adults (N = 565). Participants wrote about a moderately severe past transgression. Results supported the predictions. In Study 2, undergraduates' (N = 134) attachment styles were manipulated by varying working models of self and other. Model of self was manipulated with false performance feedback. Model of other was manipulated by altering a confederate's availability and responsiveness during a bonding exercise. Response trends replicated Study 1 with the exception of avoidance. Dismissing individuals were the most avoidant.     

Perceptions of athletic competence and fear of negative evaluation during physical education

Background. Physical education (PE) aims to enhance self‐esteem, develop sporting interests and to encourage a physically active life‐style. However, little is known about how a fear of negative evaluation (FNE), the socially evaluative aspect of social anxiety, affects children's attitudes to PE. Aim. The aim of the study was to investigate the relationships between perceived athletic competence and FNE within PE lessons, specifically looking at differences between boys and girls and primary and secondary schools. Sample. The participants were 192 children in three primary schools (N = 85, mean age = 9.5±1.1 years) and two secondary schools (N = 107, mean age = 14.5±0.8 years) from rural areas of North Wales and the Midlands region of England. Methods. The participants completed the Brief‐FNE Scale and the Self‐Perception Profile for Children immediately post‐lesson on one occasion. Results. Girls had higher FNE but lower perceptions of athletic competence than did boys. Older girls had higher FNE and lower perceived competence than the remaining three groups. Additionally, a significant and reverse but weak correlation was observed between girls' perceived athletic competence and FNE. Conclusions. The findings suggest that girls with a high FNE report lower perceptions of their athletic competence. Individuals who are high in FNE behave in ways to avoid the prospect of being evaluated negatively. However, they may seek feedback from significant others as a signal that unfavourable evaluations have been avoided. Therefore, positive, encouraging feedback used in child‐centred learning strategies may foster feelings of competence in boys and girls and could reduce the girls' social anxiety.     

Merging on mayday: subgroup and superordinate identification as joint moderators of threat effects in the context of European Union's expansion

Threat has been proposed as an important cause of prejudice with social identification moderating its effects. In the context of the expansion of the European Union, two studies (N = 216 students and N = 107 non‐students) examined how people with different levels of subgroup and superordinate identification respond to threats from an outgroup nested within the same superordinate category as the ingroup. Across experiments, a consistent finding was that participants who strongly identified with the subgroup (Germany) and the superordinate group (Europe) at the same time were most susceptible to a subtle manipulation of threat. Among these participants, threat increased prejudice (Studies 1 and 2) and ingroup projection (Study 2). Findings are discussed with regard to theoretical models of subgroup relations, especially the ingroup projection model, as well as the European integration process.

Commitment expectations in romantic relationships: Application of a prototype interaction‐pattern model

Three studies were conducted to investigate whether commitment expectations in romantic relationships can be described using a prototype interaction‐pattern model of interpersonal expectations. Participants included male and female students enrolled at a university in the United States. In Study 1, 204 participants listed interaction patterns they believed produce a sense of commitment in romantic relationships. Study 2 (N= 170) tested whether the patterns are organized around prototypes, such that some patterns are more likely to create a sense of commitment than others. In Study 3, 160 participants evaluated the effects of prototypical and nonprototypical pattern violations to verify the prototype structure further. The utility of the prototype interaction‐pattern model for analyzing commitment expectations was supported in all 3 studies.     

Testing a contact intervention based on intergroup friendship between Roma and non‐Roma Hungarians: reducing bias through institutional support in a non‐supportive societal context

Although intergroup friendships have been shown to reduce prejudice, little research has considered whether interventions fostering intergroup friendship would be effective in highly prejudicial contexts. We conducted a quasi‐experiment (N = 61) to test whether a contact‐based intervention based on intergroup friendship could reduce bias against Roma people among non‐Roma Hungarians. Participants in the contact condition engaged in a face‐to‐face interaction with a Roma person, and responded to questions involving mutual self‐disclosure. Through pre‐ and post‐test questionnaires, we observed significant positive change in attitudes and contact intentions among participants in the contact condition, while these effects were not observed among participants in the control condition. Positive change was moderated by perceived institutional norms, which corroborates the potential of contact‐based interventions.
