A Case Study of Witness Consistency and Memory Recovery Across Multiple Investigative Interviews

Access to audio recordings of five interviews (Interviews 2–6), and to the interviewer's contemporaneous notes during an initial unrecorded interview, made it possible to assess consistency across repeated attempts by a 9‐year‐old to describe her older sister's abduction from their shared bedroom. Information provided in each of the interviews was systematically analysed to determine whether each unit of information was new, consistent (repeated) or contradictory in relation to earlier reported information and whether any informative detail provided in the witness' initial interview was subsequently omitted. In addition, the witness' accounts were compared with details provided by the victim upon her rescue. This case analysis is particularly informative in light of widespread professional concerns about the effects of repeated interviewing on the quality and accuracy of children's accounts of experienced events.

Social identification structures the effects of perspective taking

Researchers who study perspective taking are generally optimistic about the potential for interventions to improve intergroup perceptions. The current research provides new insight into the conditions that frame the intergroup outcomes of perspective taking. The results show that the effects of perspective taking are not always positive but depend on perspective takers' degree of identification with the in-group. In two experiments, we demonstrated that adopting the perspective of an out-group member can have damaging effects on intergroup perceptions among group members who are highly identified with the in-group. Specifically, compared with less committed members, those who identified highly with the in-group used a greater number of negative traits to describe the out-group following perspective taking. Such perspective taking also led participants with high in-group identification to judge the out-group less favorably. Understanding how social identity concerns frame the outcome of perspective taking is crucial to its effective employment in intergroup-relations programs.     

Permission to be prejudiced: Legitimacy credits in the evaluation of advertisements

We investigated discrimination in the context of evaluating advertisements, based on the suppression model (justification‐suppression model [JSM]) of prejudice expression. Previous research has demonstrated that when people are given an opportunity to give a high rating to an ad featuring a Black model, a sense of nonprejudice is created, which, in turn, provides an opportunity to discriminate subsequently without feeling prejudiced. We extended the JSM by investigating whether the acquisition of legitimacy credits (a moral authority earned by demonstrating nonprejudice) is a sufficient condition to release the expression of prejudice. We found that subjects who first evaluated a high‐quality ad featuring a Black model felt eligible to use legitimacy credits in subsequent evaluations. But in a subsequent study, participants who acquired these credits evaluated Black model ads more negatively than White model ads only when these ads were of low quality. The implications for evaluating the subtle way that prejudice affects rating of models of color in advertisements are discussed.     

Imaging Brain Effects of APOE4 in Cognitively Normal Individuals Across the Lifespan

The ε4 allele of the apolipoprotein E (APOE4) is associated with an increased risk of developing Alzheimer’s disease (AD). Hence, several studies have compared the brain characteristics of APOE4 carriers versus non-carriers in presymptomatic stages to determine early AD biomarkers. The present review provides an overview on APOE4-related brain changes in cognitively normal individuals, focusing on the main neuroimaging biomarkers for AD, i.e. cortical beta-amyloid (Aβ) deposition, hypometabolism and atrophy. The most consistent findings are observed with Aβ deposition as most studies report significantly higher cortical Aβ load in APOE4 carriers compared with non-carriers. Fluorodeoxyglucose-positron emission tomography studies are rare and tend to show hypometabolism in brain regions typically impaired in AD. Structural magnetic resonance imaging findings are the most numerous and also the most discrepant, showing atrophy in AD-sensitive regions in some studies but contradicting results as well. Altogether, this suggests a graded effect of APOE4, with a predominant effect on Aβ over brain structure and metabolism. Multimodal studies confirm this view and also suggest that APOE4 effects on brain structure and function are mediated by both Aβ-dependent and Aβ-independent pathological processes. Neuroimaging studies on asymptomatic APOE4 carriers offer relevant information to the understanding of early pathological mechanisms of the disease, although caution is needed as to whether APOE4 effects reflect AD pathological processes, and are representative of these effects in non-carriers.     

Academic achievement and behavioral health among Asian American and African American adolescents: testing the model minority and inferior minority assumptions

The present study tested the model minority and inferior minority assumptions by examining the relationship between academic performance and measures of behavioral health in a subsample of 3,008 (22 %) participants in a nationally representative, multicultural sample of 13,601 students in the 2001 Youth Risk Behavioral Survey, comparing Asian Americans (N = 408) and African Americans (N = 2,600). Specifically, the study examined associations of students’ self-reported grades with suicide risk, substance abuse, and violent behaviors. The findings revealed that high academic performance is a protective factor against behavioral health problems for both ethnic groups. The results raise questions about the focus on high achievement among Asian Americans versus academic underachievement among African Americans. Implications for theory, research, training and practice in addressing the mental health implications of achievement behavior in Asian American and African American youth are discussed.     

Distinct and shared cognitive functions mediate event- and time-based prospective memory impairment in normal ageing

Prospective memory (PM) is the ability to remember to perform an action at a specific point in the future. Regarded as multidimensional, PM involves several cognitive functions that are known to be impaired in normal ageing. In the present study we set out to investigate the cognitive correlates of PM impairment in normal ageing. Manipulating cognitive load, we assessed event- and time-based PM, as well as several cognitive functions, including executive functions, working memory, and retrospective episodic memory, in healthy participants covering the entire adulthood. We found that normal ageing was characterised by PM decline in all conditions and that event-based PM was more sensitive to the effects of ageing than time-based PM. Whatever the conditions, PM was linked to inhibition and processing speed. However, while event-based PM was mainly mediated by binding and retrospective memory processes, time-based PM was mainly related to inhibition. The only distinction between high- and low-load PM cognitive correlates lies in an additional, but marginal, correlation between updating and the high-load PM condition. The association of distinct cognitive functions, as well as shared mechanisms with event- and time-based PM, confirm that each type of PM relies on a different set of processes.     

Stuck in the Middle: The Use and Interpretation of Mid-Points in Items on Questionnaires

Likert-type scales are commonly used when assessing attitudes, personality characteristics, and other psychological variables. This study examined the effect of varying the number of response options on the same set of 28 attitudinal items. Participants answered items using either a 4-point scale (forced choice), a 5-point scale that included a “neither” mid-point, or a 4-point scale with an option of “no opinion” presented after the item. The questionnaire also included an item asking participants what they believe the midpoint in a scale indicated. As predicted, participants’ interpretations of the midpoint varied widely with the most common responses being: “no opinion,” “don't care,” “unsure,” “neutral,” “equal/both,” and “neither.” The quantitative results showed that participants’ levels of item endorsement varied based on the response options offered. For example, “neither” was chosen more often than “no opinion” on all of the items.     

The Effect of Temporal Distance on Attitudes toward Imprecise Probabilities and Imprecise Outcomes

Many personal, managerial, and societal decisions involve uncertain or ambiguous consequences that will occur in the future. Yet, previous empirical research on ambiguity preferences has focused mainly on decisions with immediate outcomes. To close this gap in the literature, this paper examines ambiguity attitudes toward future prospects, particularly how they may differ from the attitudes toward comparable prospects in the present. On the basis of a recent paradigm, we first distinguish between two types of ambiguity: imprecise probabilities and imprecise outcomes. Then, in accordance with construal level theory, which shows that temporal distance increases the relative importance of outcomes over probabilities in evaluating prospects, we conjecture that temporal distance would moderate attitudes toward imprecise probabilities but amplify attitudes toward imprecise outcomes. Through a series of experiments, we demonstrate that when the prospects are in the future, individuals are less averse toward imprecise probabilities and more seeking toward imprecise outcomes. However, the effect is most prominent for prospects where both the probability and outcome dimensions are concurrently imprecise. The paper ends with a discussion on how dimension salience may have contributed to this result. Copyright © 2012 John Wiley & Sons, Ltd.
