Post‐identification feedback,confidence and recollections of witnessing conditions in child witnesses

Eyewitness confidence and detailed memory reports are often considered reliable indicators of the credibility of the eyewitness testimony. This study investigated how feedback concerning the accuracy of a lineup identification influences witnesses' confidence in the accuracy of their identification decision and their judgements concerning the witnessing experience. Fifty‐seven children (11–12 years) and 55 adults (17–39 years) viewed a video of a robbery and attempted to identify the culprit from a photo lineup. The culprit was not present. Participants received confirming feedback, disconfirming feedback, or no feedback on the accuracy of their identification. The confidence judgements and recollections of witnessing conditions of both children and adults were influenced by confirming and in some instances, disconfirming feedback. These findings imply that confidence and memory reports are easily distorted by non‐specific feedback and investigators should be sensitive to this particularly when dealing with vulnerable witnesses such as children.

Post‐identification feedback: exploring the effects of sequential photospreads and eyewitnesses' awareness of the identification task

Two experiments tested whether the sequential photospread procedure would protect eyewitnesses against memory distortion from post‐identification feedback. In Experiment 1, participants (N = 245) watched a videotaped event and then viewed a sequential or simultaneous target‐absent photospread. After their identification, participants were randomly assigned to hear confirming feedback ‘Good, you identified the suspect.’ or no feedback (control). Participants then completed a questionnaire assessing testimony‐relevant retrospective judgments. Post‐hoc analyses revealed that the sequential photospread only protected against post‐identification feedback effects for participants who reported that, while they watched the video, they did not expect to make an identification. A second experiment (N = 320) was conducted to manipulate expectations about the identification task and the presence of the target. This experiment revealed that the post‐identification feedback effect persists across witnesses' expectations and lineup type. Copyright © 2006 John Wiley & Sons, Ltd.     

Emotional discussions reduce memory recall

People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses’ discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.     

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.

Emotional impact feedback affects how people remember an analogue trauma event

Do external motivational processes—in the form of social influences—shape people's memories for trauma? In this experiment, we examined the effects of social influence on memory and post-traumatic stress disorder (PTSD) symptomology for an analogue traumatic event. Seventy-two participants watched a distressing film; some received feedback about others' reactions to the film that either emphasised or downplayed the distressing nature of the film; control participants received no feedback. A week later, participants reported their symptoms, rated their memory on a number of characteristics and we tested their memory for the film's content. Participants who received feedback downplaying the film reported fewer PTSD-related analogue symptoms and weaker memory characteristics than their counterparts. The results suggest that people's memory phenomenology and analogue symptoms are influenced by others' feedback, but only when others' reactions downplayed the distressing nature of the film.     

Improving specific autobiographical memory in older adults: impacts on mood,social problem solving,and functional limitations

Older adults have difficulty recalling specific autobiographical events. This over-general memory style is a vulnerability factor for depression. Two groups receiving interventions that have previously been successful at reducing over-general memory in depressed populations were compared to a control group. Participants were healthy older adults aged ≥70 years: memory specificity training (MEST; n = 22), life review (n = 22), and control group (n = 22). There were significant improvements in autobiographical memory specificity in the MEST and life review groups at post-training, relative to the control group, suggesting that over-general memory can be reduced in older adults. Change in social problem solving ability and functional limitations were related to change in autobiographical memory specificity, supporting the suggested role of specific retrieval in generating solutions to social problems and maintaining independence. Qualitative analysis of participants’ feedback revealed that life review may be more appropriate for older adults, possibly because it involves integrating specific memories into a positive narrative.     

Memory distortions: When suggestions cannot be easily ignored

In the present study, the persistence of personal false memories (FMs) after social feedback that denies their truth was assessed. Participants imitated actions performed by the experimenter (Session 1) and watched a doctored video with performed and critical “fake” actions (Session 2), followed by a memory rating and a recognition task. A few days later (Session 3), participants were clearly told that some memories were false and received daily reminders of the correct list of objects/actions before testing their memory again in Session 4. Results of both memory ratings and recognition indicated effective FM implantation. Interestingly, response times for correct rejections were longer for fake than true objects, suggesting participants struggled to ignore false suggestions. Crucial for our aim, Session 4 showed that FM persisted also after the debriefing and repeated presentations of correct list of objects/actions, suggesting that FMs for actions are rather difficult to discard.     

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.     

Discounting input from older adults: the role of age salience on partner age effects in the social contagion of memory

Three experiments examined the impact of partner age on the magnitude of socially suggested false memories. Young participants recalled household scenes in collaboration with an implied young or older adult partner who intentionally recalled false items. In Experiment 1, participants were presented with only the age of their partner (low age-salience context); in Experiment 2, participants were presented with the age of their partner along with a photograph and biographical information about their partner (high age-salience context); in Experiment 3, age salience was varied within the same experiment. Across experiments, participants in both the low age-salience and high age-salience contexts incorporated their partners’ misleading suggestions into their own subsequent recall and recognition reports, thus demonstrating social contagion with implied partners. Importantly, the effect of partner age differed across conditions. Participants in the high age-salience context were less likely to incorporate misleading suggestions from older adult partners than from young adult partners, but participants in the low age-salience context were equally likely to incorporate suggestions from young and older adult partners. Participants discount the memory of older adult partners only when age is highly salient.     

Mad enough to see the other side: Anger and the search for disconfirming information

The current research explored the effect of anger on hypothesis confirmation—the propensity to seek information that confirms rather than disconfirms one's opinion. We argued that the moving against action tendency associated with anger leads angry individuals to seek out more disconfirming information than sad individuals, attenuating the confirmation bias. We tested this hypothesis in two studies of experimentally primed anger and sadness on the selective exposure to hypothesis confirming and disconfirming information. In Study 1, participants in the angry condition were more likely to choose disconfirming information than those in the sad or neutral condition when given the opportunity to read more about a social debate, and reading the disconfirming information affected their subsequent attitude. Study 2 measured participants' opinions and information selection about the 2008 US Presidential Election and their desire to “move against” a person or object. Participants in the angry condition reported a greater tendency to oppose a person or object, which resulted in the attenuation of the confirmation bias.     

The opportunity to choose enhances long-term episodic memory

ABSTRACT

Episodic memory is typically studied under conditions that treat participants as passive agents. Here we sought to explore how actively engaging in ongoing naturalistic occurrences affects long-term episodic memory. Participants viewed 40 short movie clips that depicted a protagonist that conversed with the participants. In each clip, they were either offered the chance to (supposedly) determine the clip’s continuation (active condition), or let the computer decide for them (passive condition). Participants returned either two days or one week after the experience to undergo a true/false memory test for the clips’ details and a two-alternative recognition test for the choices made. Memory performance for both groups was superior for information and choices conveyed in the active vs. passive condition. These findings suggest that the sense of actively influencing the unfolding of events is beneficial to long-term memory of the experience at large, baring potential interventions in the fields of education and cognitive enhancement.     

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.

Postidentification feedback effects on face recognition confidence: evidence for metacognitive influences

Information given to witnesses after an identification decision greatly alters their impressions of the original event and importantly, their identification confidence. Two experiments investigated the possibility that the effect of feedback on confidence may be altered according to the strength of the witness's cues to accuracy. Experiment 1 used a manipulation of exposure duration to alter recognition accuracy prior to the delivery of confirming, disconfirming or no feedback. While the feedback effect was not different across exposure duration conditions, decisions that were made more quickly were less likely to show large changes in confidence due to feedback. Experiment 2 manipulated the distinctiveness of faces and showed that the effects of feedback on confidence, and on the resolution of the confidence judgement, were more pronounced when disconfirming feedback was given for distinctive faces and when confirming feedback was given for typical faces. These studies showed that the impressions that participants formed of their likely accuracy might moderate the effects of feedback on decision confidence.

Discrete changes in the frequency and functions of autobiographical reminiscence in Huntington's disease

ABSTRACT

Autobiographical memory is widely posited to serve self, social and directive functions. Recent evidence suggests marked autobiographical memory impairments in Huntington's disease (HD), however, no study to date has determined how the perceived functions of autobiographical reminiscence may be altered in HD. The current study aimed to assess the self-reported frequency and function of autobiographical reminiscence in HD. We assessed autobiographical reminiscence in late premanifest (n?=?16) and early stage HD (n?=?14), relative to healthy controls (n?=?30). Participants completed the Thinking About Life Experiences Scale Revised (TALE-R), which measures three putative functions of autobiographical memory (self, social, directive). People with manifest HD reported talking less frequently about the past compared to controls. In contrast, no group differences were found in terms of thinking about the past. Manifest HD participants further reported using their autobiographical memories for social functions less frequently compared to controls. No other group differences were evident in terms of self or directive functions of autobiographical memory. These self-report findings complement recent reports of autobiographical memory disruption on performance-based tasks in HD. Future studies exploring how changes in autobiographical reminiscence impact a sense of self continuity in HD will be important in this regard.     

Compared to what? The effects of a frame of reference on older adults’ subjective memory

It is often unclear what comparisons older adults make when evaluating their own memory. If thinking about their memory relative to others, they may assess their own abilities differently than if comparing it to their past capabilities. To test the effect of reference frames on memory assessments and memory performance, we randomly assigned 120 older adults to one of three conditions in which we manipulated frames of reference (control, past-self comparison, or other adults comparison) on a memory self-efficacy questionnaire. Participants also completed general and specific memory predictions and an objective memory test. Participants in the past-self condition reported significantly lower global memory self-efficacy compared with the other adults and control conditions. No condition differences emerged for memory predictions, objective memory, or the likelihood of over- or underpredicting memory performance. These findings suggest that reference frames impact global memory self-efficacy, but do not influence the accuracy of subjective memory judgments.     

Stigma as framed on YouTube: Effects of personal experiences videos on students’ beliefs about medicalizing intersex

People with physical intersex characteristics can be subject to medical interventions that risk human rights to bodily integrity and self‐determination. Proponents and opponents of medicalization use personal narrative videos on YouTube to frame intersex as a stigma best understood through a medical or social identity frame. Ninety‐nine psychology students watched one of two YouTube videos with either a medical or social identity frame, or participated in a comparison group who watched no video. Participants extracted the videos’ medical or social identity framing in their own words. The social identity video increased participants’ sense that medicine was more harmful and less beneficial, and the medical video decreased participants’ sense that medicine was harmful. Although the videos aimed at bringing about social understanding of intersex people, neither video impacted stigmatizing beliefs about intersex people as a group. Rather, effects of the videos on beliefs about harms of medicalization were moderated by two stigma measures; social distance and gender binary beliefs. Medical intervention on intersex has been justified, in part, on grounds that stigma is inevitable. While intersex stigma has rarely been empirically examined, the present study shows that people with less propensity to stigmatize see less benefit from medicalizing intersex traits and are more open to learning few framings from personal experience videos.     

The effects of confederate influence and confidence on the accuracy of crime judgements

Building on recent work which has investigated social influences on memory and remembering, the present experiment examined the effects of social pressure and confederate confidence on the accuracy and confidence of eyewitnesses. Sixty undergraduate participants watched a video of a staged mugging and then answered questions about the video out loud in the presence of either one or three confederates who had also watched the film with them. Unbeknownst to the participant, the confederate(s) always gave incorrect responses to four out of the eight questions. Participants and confederates were also asked to give confidence scores out loud for each of their answers. Again, unbeknownst to the participant, the confederate(s) always expressed either high or low confidence scores for the incorrect information, depending on condition. Participants gave fewer correct answers, and were less confident, in the presence of three, as opposed to one, confederates. Participants were also more confident, yet no more accurate, when the confederate(s) gave high, as opposed to low, confidence scores. Thus the presumed independence of evidence given by multiple witnesses cannot be safely assumed.     

Social support from friends predicts changes in memory specificity following a stressful life event

ABSTRACT

Exposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N?=?143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity.     

Reflecting on how we remember the personal past: missing components in the study of memory appraisal and theoretical implications

The current paper offers a selective review of the study of memory appraisal, focusing on recollections of the personal past, with the goal to bring attention to a missing component in this study. To date, memory appraisal studies have concentrated on participants’ assessments of the content of their personal recollections (e.g., their perceptual detail and story-like feel), including beliefs about the accuracy of that content. Participants’ assessments of reflection processes accompanying their recollections (e.g., a sense of piecing-together recollection fragments) have yet to be extensively examined. The lack of information on process-based appraisals is related to prior studies’ procedural constraints (e.g., kinds of cue prompts and their timing, minimal opportunities for reflection). Reasons for addressing this missing component provide the central themes of the paper. The reasons emerge from the analysis of autobiographical cueing studies, including integration of narrative research studies and autobiographical works. The analysis leads to suggestions for future research involving the use of personal narratives that are intended to address critiques of reconstruction accounts and unresolved questions in the study of memory appraisal.
