Context effects in episodic studies of verbal and facial memory: A review

Memory research has in the last fifteen years been marked by a considerable interest in context effects. This review begins by examining experimental manipulations of verbal and environmental context in verbal memory. This is followed by a more extensive review of episodic studies of face recognition that have examined the effects of varying the background in which a face is portrayed, the room of testing, and the presence of guided instructions. The relevance of these findings to eyewitness memory is also considered. Discrepancies in the literature are pinpointed with theoretical discussion centering around encoding specificity theory (Tulving & Thomson, 1973) and Baddeley and Woodhead’s (1982) distinction between “independent” (extrinsic) and “interactive” (intrinsic) context effects. The review ends with an evaluation of some recent models of memory and face recognition in an attempt to provide a framework within which to interpret the context effects in the literature.     

The cognitive interview: Its origins,empirical support,evaluation and practical implications

This paper provides a background to current research on the cognitive interview (CI), which is a set of cognitive retrieval techniques designed to facilitate memory search (for example, via reinstatement of contextual cues). One of the principal aims of this research is to identify and develop techniques which police investigators can themselves use. A series of studies were conducted at the University of California, Los Angeles, using police officers as interviewers and students, non-students and children as witnesses to realistic crimes. In all studies the CI elicited significantly more correct information with no apparent increase in errors or confabulations. The CI has been tested in a field study involving police officers in Florida. This paper will critically review this research, as well as more recent unpublished work including CI studies conducted in Germany and the UK. Some important modifications of the original CI procedure are described, and there is a theoretical discussion and explanation of the various components of the CI procedure. Finally, we will consider applications of the CI in clinical and organizational settings.     

Understanding pretrial publicity: predecisional distortion of evidence by mock jurors

Prejudicial pretrial publicity (PTP) constitutes a serious source of juror bias. The current study examined differences in predecisional distortion for mock jurors exposed to negative PTP (N-PTP) versus nonexposed control participants. According to work by K. A. Carlson and J. E. Russo (2001), predecisional distortion occurs when jurors bias new evidence in favor of their current leading party (prosecution or defense) rather than evaluating this information for its actual probative properties. Jury-eligible university students (N=116) acted as jurors in a mock trial. Elevated rates of guilty verdicts were observed in the N-PTP condition. Predecisional distortion scores were significantly higher in the N-PTP condition and reflected a proprosecution bias. The effect of prejudicial PTP on verdict outcomes was mediated by predecisional distortion in the evaluation of testimony. Results are discussed in relation to motivated decision making and confirmation biases.     

Age differences in accuracy and choosing in eyewitness identification and face recognition

Studies of aging and face recognition show age-related increases in false recognitions of new faces. To explore implications of this false alarm effect, we had young and senior adults perform (1) three eye-witness identification tasks, using both target present and target absent lineups, and (2) and old/new recognition task in which a study list of faces was followed by a test including old and new faces, along with conjunctions of old faces. Compared with the young, seniors had lower accuracy and higher choosing rates on the lineups, and they also falsely recognized more new faces on the recognition test. However, after screening for perceptual processing deficits, there was no age difference in false recognition of conjunctions, or in discriminating old faces from conjunctions. We conclude that the false alarm effect generalizes to lineup identification, but does not extend to conjunction faces. The findings are consistent with age-related deficits in recollection of context and relative age invariance in perceptual integrative processes underlying the experience of familiarity.     

Live Showups and Their Influence on a Subsequent Video Line‐up

A live showup (known as a street identification in the UK) allows the perpetrator to be identified shortly after a street crime. If the suspect disputes the identification, a video line‐up often ensues. Four experiments examined the reliability of live showups and their influence on a subsequent video line‐up using realistic procedures and conditions. Similar proportions of culprits and innocent suspects were identified from live showups and video line‐ups. Both culprits and innocent suspects previously identified were likely to be identified again in a subsequent line‐up, with delays from a few minutes to a month. Only a weak effect of clothing bias was observed. There was strong evidence of commitment to a previous identification but no reliable evidence of source monitoring errors. The results suggest that a live showup is not less fair than a line‐up, but the use of repeated identification procedures introduces an unfair bias against innocent suspects.

Examining the impact of acculturative stress on body image disturbance among Hispanic college students

This study investigated the impact of acculturative stress on psychological well-being and body image disturbance in a sample of female and male Hispanic individuals. The unique protective effects of differing social support sources, including family and peer support, were examined against acculturative stress and body image disturbance. A total of 399 participants of Hispanic origin were recruited from Texas Tech University in West Texas. Students completed a battery of measures of acculturative stress and internalization of the thin ideal, as well as perceived social support. Hierarchical regression analyses indicated that acculturative stress is a significant positive predictor of body image disturbance among Hispanic college students. Thin ideal internalization was found to mediate this relationship such that acculturative stress was associated with heightened body image disturbance through its impact on thin ideal internalization. Social support significantly reduced acculturative stress as well as body image disturbance but did not moderate the relation between these 2 factors. Results highlight the importance of considering acculturative stress as a strong predictor of body image disturbance among college students of Hispanic origin. The mechanisms of influence of acculturative stress on body image disturbance are discussed in relation to thin ideal internalization. The protective role of social support on these negative psychological outcomes is also clarified. This study is the first to examine these issues in a sample of female and male Hispanic college students and provides avenues for clinical interventions and future trials with diverse populations.     

Talking about visually perceived events: Communication effects on eyewitness memory

Communicators' tuning of a message about a social target to their audience's evaluation can shape their representation of the target. This audience‐tuning effect has been demonstrated with ambiguous text passages as input material. We examined whether the effect also occurs when communicators learn about the target's behaviours from visual (nonverbal) input material. In Experiment 1, participants watched a soundless video depicting ambiguous behaviours of a target, described the video to an audience who liked (vs. disliked) the target, and subsequently recalled the video. Both message and recall were biased towards the audience's judgement. In Experiment 2, the video depicted a forensically relevant event, specifically ambiguous behaviours of two persons involved in a bar brawl. Participants tuned their event retellings to their audience's responsibility judgement and remembered the event accordingly. In both experiments, the effect of the audience's judgement on recall was statistically mediated by the extent to which the message was tuned to the audience. The more participants experienced a shared reality with their audience the stronger was the message‐recall correlation (Experiment 2). We conclude that the audience‐tuning effect for visually perceived information depends on the communicators' creation of a shared reality with their audience.

Development and use of behavior and social interaction software installed on Palm handheld for observation of a child’s social interactions with the environment

In settings in developing countries, children often socialize with multiple socializing agents (peers, siblings, neighbors) apart from their parents, and thus, a measurement of a child’s social interactions should be expanded beyond parental interactions. Since the environment plays a role in shaping a child’s development, the measurement of child-socializing agents’ interactions is important. We developed and used a computerized observational softwareBehavior and Social Interaction Software (BASIS) with a preloaded coding scheme installed on a handheld Palm device to record complex observations of interactions between children and socializing agents. Using BASIS, social interaction assessments were conducted on 573 preschool children for 1 h in their natural settings. Multiple screens with a set of choices in each screen were designed that included the child’s location, broad activity, state, and interactions with child-socializing agents. Data were downloaded onto a computer and systematically analyzed. BASIS, installed on Palm OS (M-125), enabled the recording of the complex interactions of child-socializing agents that could not be recorded with manual forms. Thus, this tool provides an innovative and relatively accurate method for the systematic recording of social interactions in an unrestricted environment.     

How love and lust change people’s perception of relationship partners

Because love is related to thoughts in the distant future and lust triggers thoughts related to the present, based on construal level theory, we propose a link between love and a global processing style as well as a link between lust and a local processing style. These processing styles should further expand to partnership evaluations, partially explaining halo phenomena. In Study 1, college students and senior participants were primed by either imagining a walk with a person they were in love with, or a one-night stand. In Study 2, love and lust were primed subliminally. In all studies, love priming enhanced global, holistic processing and halos, whereas lust priming enhanced local, detail oriented processing and reduced halos. Moreover, in Study 1, temporal distance mediated the effects. Implications for research of moods on processing styles, partner perception, and the distinction between love and lust are discussed.
