The Effect of Backloading Instructions on Eyewitness Identification from Simultaneous and Sequential Lineups

The sequential lineup is multifaceted, including serial presentation of faces, multiple decisions, and often backloading (indicating to an eyewitness that a lineup contains more photos than there actually are). We evaluated the effect of backloading instructions on response bias and sensitivity with an eyewitness identification paradigm. Importantly, we included an ‘undisclosed’ condition that provided no information to participants about the number of lineup members to expect. Experiment 1 (N = 780) tested sequential lineups; Experiment 2 (N = 532) tested simultaneous lineups. As predicted, signal detection analysis showed that backloading induced participants to be more conservative in choosing from both lineup types, but did not affect d′. We conclude that the criminal justice system should be mindful of this shift in response bias, as it has implications for both guilty and innocent suspect identifications.

Age‐related Changes in Creative Thinking

Age‐related differences in cognitive processes were used to understand age‐related declines in creativity. According to the Geneplore model (Finke, Ward, & Smith, 1992), there are two phases of creativity — generating an idea and exploring the implications of the idea — each with different underlying cognitive processes. These two phases are measured in the Creative Invention Task (CIT; Finke, 1990). Younger adults (n = 41) and older adults (n = 41) completed the CIT, the Torrance Tests of Creative Thinking (TTCT), and a measure of working memory capacity (Paper Folding test). In addition, the CIT was scored by both younger and older adults. There were age‐related declines on both phases of the CIT, but not on the TTCT. These declines were noted by both the younger and older raters. After adjusting for working memory capacity, however, age‐related differences on the CIT were nonsignificant.     

Adult Age‐Related Differences in the Misinformation Effect for Context‐Consistent and Context‐Inconsistent Objects

The present study examined age‐related differences in the misinformation effect for objects that were consistent or inconsistent with their environmental settings. Young and older adults viewed one of two slide sequences, each containing context‐consistent items (e.g., a blender in a kitchen setting or a saw in a woodshop setting) and context‐inconsistent items (a saw in a kitchen setting or a blender in a woodshop setting). After receiving misinformation through post‐event narratives, participants received tests of yes/no recognition requiring remember/know judgments (Experiments 1–3) and source monitoring (Experiments 2 and 3) for slide details. Although age‐related differences in the misinformation effect were nonreliable, older adults tended to report misinformation as remembered more often than young adults, and source monitoring tests reduced the misinformation effect for both age groups. Misinformation effects were equivalent or larger for inconsistent objects than for consistent objects. Theoretical and practical implications of these results are discussed.

Age‐Related Differences in Ethnic Prejudice: Evidence of the Mediating Effect of Right‐Wing Attitudes

The present study revealed age‐related differences in ethnic prejudice in a heterogeneous (total N = 1,308) and a representative (N = 800) sample, using measures of blatant and subtle prejudice. The relationship between age and blatant and subtle prejudice was found to be fully mediated by right‐wing social‐cultural attitudes (i.e. authoritarianism and cultural conservatism).

Using Dynamic Panel Models to Study Age‐related Differences and Time‐related Changes in Personality

Along with an increasing interest in the plasticity and role of personality across the adult lifespan comes the need for a diverse set of innovative statistical approaches to study it. With this paper, we set out to illustrate some of the possibilities and challenges in modelling age‐related differences and time‐related changes in personality psychology by means of dynamic panel models. To this end, we first distinguish between the study of age‐related differences and time‐related changes and demonstrate how the treatment of age and time as either discrete or continuous variables implies important modelling choices. Second, we present a selection of four example cases that address the topic of age moderation in diverse matters and with different objectives. Based on our cross‐tabulation of age and time as discrete and continuous variables, the first two example cases represent fairly well‐established models (cases A and B), whereas the remaining cases are used to illustrate current developments in the field (cases C and D). We close the paper with some final remarks on current limitation and future research directions. © 2019 European Association of Personality Psychology     

Repetition and Reconfiguration: Demand‐Based Confabulation in Initial Eyewitness Memory

Repeated recall, as a result of repeated questioning, is typical of situations involving eyewitness evidence. The present study addressed questions of eyewitness performance with reference to repeated questioning in an initial interview, in a format based on actual police procedures. This experiment focused on eyewitness accuracy, eyewitness confidence, and the addition of false details to eyewitness accounts. Ninety‐two adult respondents were asked to recall all the information they could from a single viewing of a scene depicting an assailant aiming a handgun at a victim. This initial question was followed by three additional questions, in which respondents were asked to report any additional details they could recall. On average, respondents provided several times as many correct as false details to the initial question. However, performance deteriorated significantly to the three subsequent questions; on average, across the three subsequent questions, witnesses recalled nearly as much false as accurate information. Witness confidence was positively related to amount of accurate information recalled. However, confidence was also positively related to the number of instances of erroneous recall. These results indicate that reconfigurative dynamics begin to operate, producing confabulated responses in response to questioning demands, as early as the initial interview. This work may also help to clarify the critical relationship between accuracy and confidence in eyewitness reportage, at least within the framework reflected by the present research.

Confidence and Eyewitness Identifications: The Cross‐Race Effect,Decision Time and Accuracy

Participants encountered same‐race and cross‐race faces at encoding, completed a series of line‐up identification tests and provided confidence ratings by using one of nine different confidence scales. Confidence was less well calibrated with identification accuracy when participants selected a cross‐race than a same‐race face because of overconfidence. By contrast, there was no cross‐race effect on confidence–accuracy calibration when participants responded ‘not present’. Whereas confidence was a very strong predictor of accuracy for fast identifications of a line‐up face, this was much less the case for slower decisions. Highly confident identifications showed a dramatic drop in accuracy from faster decisions to slower decisions, whereas there was little change in accuracy between faster and slower decisions for moderately confident or weakly confident identifications. Finally, we observed little influence of the format of the nine different confidence scales: numerical and verbal scales produced comparable calibration scores, as did scales with few or many points.

Creative at Each Age: Age‐Related Differences in Drivers of Workplace Creativity from an Experience Sampling Study

Creativity and innovation are essential agents for change processes and accelerating technical development. Having to face challenges, such as demographic change, organizations require individuals who are creative and innovative at each age. Previous research identified affect as a crucial determinant of creativity, even though empirical findings showed inconsistencies. Drawing on literature on age‐related changes in affective experiences, we investigated the moderating effect of employees’ age on the association between daily positive and negative affect and creativity using a daily diary study. A total of 116 employees responded to daily questionnaires twice a day over five consecutive working days. As expected, hierarchical linear modeling analyses revealed differential effects regarding the affect‐creativity association, dependent on employees’ age. Although older employees were most creative on days when they experienced a high level of positive affect (compared to their mean level of positive affect), younger employees were particularly creative when experiencing negative affect (compared to their mean level of negative affect). We discuss practical implications on how organizations could provide creativity‐enhancing work environments for employees at each age.     

Age‐related Differences in the Free‐recall Accounts of Child,Adolescent, and Adult Witnesses

Many researchers have examined the factors that affect children's ability to provide eyewitness evidence, leading to significant reform in policy and practice. In stark contrast, there has been virtually no eyewitness research conducted with adolescents, even though adolescents are still undergoing developmental changes that are likely to affect eyewitness performance. We compared the eyewitness performance of children, adolescents, and adults by showing them a brief film clip depicting a simulated crime and using cognitive interview instructions to elicit free‐recall accounts. Adolescents provided more information than children, but less information than adults. Accuracy did not differ with age. These data suggest that, like children, adolescents could benefit from specialised interview techniques that help them provide more complete accounts. Across all three age groups, individual differences in cognitive functioning contributed to variation in eyewitness performance, and eliciting a second free‐recall account increased the amount of information reported.

Age‐related differences in delay discounting: Immediate reward,reward magnitude,and social influence

Delay discounting refers to the tendency of individuals to subjectively devalue rewards that are to be received in the future, with high rates of delay discounting being associated with a variety of maladaptive life outcomes (e.g., unhealthy dietary and exercise behaviors). The current study explored the psychological and social processes involved in adult age‐related differences in delay discounting of monetary rewards. Younger adults exhibited higher levels of delay discounting than older adults. This increased level of patience in older adults was found whether smaller‐sooner rewards were to be received immediately or in the future. However, there was an interaction with reward magnitude, whereby younger adults exhibited higher levels of delay discounting for smaller reward magnitudes but not larger reward magnitudes. Social influence on delay discounting was investigated by having participants complete three phases of the delay‐discounting task: an individual precollaboration phase, a collaboration phase in age‐group‐matched dyads, and an individual postcollaboration phase. A convergence effect was observed in that dyad members' postcollaboration choices were significantly more similar compared to their baseline choices during the precollaboration phase. Moreover, levels of convergence were comparable between younger and older adults, suggesting age invariance in social influence on delay discounting. The current results demonstrate a degree of malleability in delay discounting that extends into older adulthood, making interventions targeting the construct a promising avenue for future research.     

Beliefs About Older Workers' Learning and Development Behavior in Relation to Beliefs About Malleability of Skills,Age‐Related Decline,and Control1

This study investigated beliefs about older workers' ability and inclination to develop career‐relevant skills, concepts that have not been empirically examined previously in any depth. Two sets of distinct but conceptually related variables were examined in relation to these beliefs. First, participants' implicit theory of abilities (whether they are fixed or changeable) was investigated, and was not found to predict beliefs about older workers' ability or inclination to develop. Second, their beliefs about the age‐related decline of learning‐relevant abilities and the controllability of such decline were examined. Beliefs about the decline of such abilities significantly predicted beliefs about older workers' ability to develop and beliefs about their inclination to develop. A significant relationship was also found between beliefs about controllability of decline and beliefs about older workers' learning goal orientation. Implicit theories significantly predicted beliefs about controllability of decline. These results empirically link research on beliefs about age‐related decline of abilities with the older worker stereotype literature. The results also link literature on beliefs about controllability of decline with literature on implicit theories of skill malleability.     

Eyewitness Memory and Metamemory in Product Identification: Evidence for Familiarity Biases

Research on the reliability of eyewitness memory for criminal events has been extensively studied, but eyewitness memory in civil cases has not. However, many of these civil cases revolve around eyewitness memory for events that transpired decades ago. We have developed a paradigm with which to study memory for specific product brand identification, a common question in civil cases involving product liability. Participants were asked to follow recipes and were then given surprise memory tests on the specific brands of products used. In addition, they were asked to report their subjective confidence for each response. Memory and performance was poor after even a brief delay, as was metamemory accuracy: Confidence regarding brand name recall was a poor indicator of accuracy. Participants also displayed a strong familiarity bias. They frequently reported using familiar, common brands, when no such products were actually used. This was especially true at longer delays, after which false identification of familiar products was twice as common as correct responses.     

Crime Type,Perceived Stereotypicality,and Memory Biases: A Contextual Model of Eyewitness Identification

The fallibility of eyewitness identifications is well documented. Nevertheless, research has yet to assess the possibility that the type of crime committed systematically influences who eyewitnesses mistakenly identify. We address this oversight by presenting a contextual model of eyewitness identification (CMEI). The CMEI asserts that discrete crimes automatically activate distinct stereotypes about a perpetrator's appearance. Depending on the congruence between these stereotypes and the perpetrator's actual appearance, eyewitnesses will remember the perpetrator as appearing more (or less) representative of his or her group (i.e., higher or lower on perceived stereotypicality). Estimator and system variables are posited to affect identifications at different stages of the identification process. The literatures on stereotype activation, perceived stereotypicality, and stereotype‐consistent memory biases are reviewed to support the CMEI. Our conceptual integration provides a model of eyewitness identification that explains when mistaken identifications are likely to occur and who they are likely to affect.

Remembrance of Eyewitness Testimony: Effects of Emotional Content,Self‐Relevance,and Emotional Tone1

This experiment concerned the effects of emotional content, self‐relevance, and emotional tone of testimony on memory. Eyewitness accounts of 4 events were constructed that systematically differed in emotionality and self‐relevance. The testimony, captured on videotape, was expressed with or without negative emotion. After viewing one of the videotaped accounts, participants were administered cued‐recall and recognition memory tests. Significant main effects indicated that participants best remembered testimony that was emotional in content, self‐relevant, and negatively expressed. Although emotional content and self‐relevance interacted to affect state anxiety, the latter did not mediate memory effects. Overall, significant gender differences in state anxiety but not memory emerged. Implications for understanding the influence of emotion on juror memory are discussed.     

A Video Recall Study of In‐session Changes in Sentiment Override

This study examines in‐session changes in sentiment override over the first three sessions of couple therapy. Couples viewed a video recording of therapy sessions immediately after each of the first three sessions and continuously rated their level of sentiment override. Ninety‐eight changes were randomly chosen for analysis. Three talk turns prior to each change was coded using the Family Relational Communication Control Coding System. Results show that changes in sentiment override occur frequently. Repeated incidents of communication control were related to negative change in sentiment override for females. Repeated incidents of being left out of the conversation were related to negative changes in sentiment override for females and positive changes for males.     

Co‐Witness Confidence,Conformity, and Eyewitness Memory: An Examination of Normative and Informational Social Influences

We explored conformity and co‐witness confidence in eyewitness memory. Confederates provided misleading information and confidence ratings during a cued recall test, and participants publicly provided answers to this test in turn. Participants performed memory tests with a confederate, then completed individual memory tests. Results indicated that confederates who answered questions prior to participants impacted their public and private memory reports for accurate information but only impacted public reports for misleading information. Participants' confidence in their performance in the presence of a confederate mirrored the confederate's confidence levels, suggesting a confidence conformity effect. Results are explained in terms of differential effects of informational and normative influence for accuracy and confidence in co‐witness memory reports.

Age‐related differences in subjective recollection: ERP studies of encoding and retrieval

The ability to mentally re‐experience past events improves significantly from childhood to young adulthood; however, the mechanisms underlying this ability remain poorly understood, partially because different tasks are used across the lifespan. This study was designed to address this gap by assessing the development of event‐related potential (ERP) correlates associated with subjective indices of recollection. Children, adolescents, and adults performed Tulving's ( 1985 ) remember/know paradigm while ERPs were recorded during memory encoding (Experiment 1) and retrieval (Experiment 2). Behaviorally, children recognized fewer items than adolescents and adults. All age groups reliably made subjective judgments of recollection, although the ability to make these judgments improved with age. At encoding, the ERP effect associated with recollection was present and comparable across age groups. In contrast, the ERP effect associated with recollection at retrieval differed as a function of age group; specifically, this effect was absent in children, topographically widespread in adolescents, and, consistent with previous literature, maximal over left centro‐parietal leads in adults. These findings suggest that encoding processes associated with the subsequent subjective experience of recollection may be similar among children, adolescents, and adults and that age‐related improvement in recollection may be primarily attributable to the development of processes that follow the initial encoding of stimuli (i.e., consolidation, storage, retrieval).
