Understanding what students bring to the classroom: moderators of the effects of diversity courses on student attitudes

We investigated the impact of required diversity courses on students' understanding of racial inequality and their social development with regard to racial outgroups, with a specific focus on the effects of student race and empathy as moderators of diversity course effectiveness. First-semester students (N = 173), enrolled in either diversity courses or introduction to psychology, completed surveys at the beginning and end of the semester. Diversity courses increased understanding of White privilege, acknowledgment of blatant racism, and intersectional consciousness overall, but had a greater impact on intersectional consciousness for White students compared with students of color. White students taking diversity courses experienced a reduction in Protestant work ethic ideology that was absent for White students in psychology courses and for all students of color. Notably, empathy moderated the effect of diversity courses on both outgroup comfort and willingness to act to promote diversity.     

Replicating the five factor model of personality in a psychiatric sample

In this study we examined whether the factor structure and traits of the five-factor model of personality (FFM), derived from non-clinical samples, could be replicated in a sample of psychiatric patients. The revised NEO Personality Inventory (NEO PI-R) was administered to a study group of psychiatric patients (n=176). The test scores from these patients were intercorrelated, factor analyzed and the obtained factor structure was then compared to the factor structure of the normative data from the NEO PI-R. The factor structure from the psychiatric study group and that from the normative sample were virtually identical, with all five factors showing significant congruence. These results argue favorably for the clinical applicability of the FFM with psychiatric patients.     

A new processing model for predicting performance on Pascual-Leone's test of M-space

A new model is proposed for explaining children's performance on Pascual-Leone's test of M-space. The model differs from Pascual-Leone's in three regards. (1) It assumes that children do not stop sampling a compound stimulus until every simple stimulus in their field of attention has already been noticed and responded to. (2) It assumes that the probability of sampling different combinations of simple stimuli conforms to the laws of Maxwell-Boltzman statistics rather than Bose-Einstein statistics. (3) It assumes that children's ability to detect all the simple stimuli in a compound stimulus is highly dependent both on the relative saliencies of the simple stimuli and on the length of time for which the compound stimulus is exposed. Using the developmental values of M hypothesized by Pascual-Leone, and standard techniques of computer simulation, the new model is used to generate theoretical performance curves for children at four different age levels and seven different levels of stimulus complexity. It is shown that the predicted performance curves for an exposure time of 5 sec provide a reasonable fit to the data originally reported by Pascual-Leone (1970), and that the predicted performance curves for an exposure time of 10 sec provide a reasonable fit to data obtained more recently by Parkinson (1976). Finally, it is shown that the order of children's responses as well as the number of their responses can be predicted. Two conclusions are drawn. (1) The new processing model offers a viable alternative to the model originally proposed by Pascual-Leone. (2) Regardless of which processing model is employed, the M-values originally postulated by Pascual-Leone are valid.     

Interactive versus passive dynamics and the exploratory analysis of multivariate data

In two experiments, we examined subjects’ ability to infer structure from three-dimensional data presented dynamically in interactive versus passive mode and in static scatterplots. Accuracy of estimating the number of clusters in three-dimensional data sets was measured for each of these conditions, as a function of cluster discriminability.     

Nonsuicidal Self-Injury and Attachment to God or a Higher Power

The relationship between nonsuicidal self-injury (NSSI) and spirituality is an emerging area of research deserving additional investigation. The authors examined the link between NSSI and attachment to God or a higher power among college students (N = 516). They found a statistically significant relationship between anxious attachment to God or a higher power and NSSI and avoidant attachment to God or a higher power and NSSI. Researchers and counselors can draw implications from these findings.     

Super-recognisers: Face recognition performance after variable delay intervals

Outstanding long-term face recognition of suspects is a hallmark of the exceptionally skilled police ‘super-recognisers’ (SRs). Yet, research investigating SR's memory for faces mainly employed brief retention intervals. Therefore, in Experiment 1, 597 participants (121 SRs) viewed 10 target videos and attempted identification of targets from 10 target-present line-ups after 1–56 days. In Experiment 2, 1,421 participants (301 SRs) viewed 20 target videos, and after a baseline of no delay to 28 days,—10 target-present and 10 target-absent line-ups, to assess correct line-up rejections. Overall, delay positively correlated with hits but not with correct rejections. Most, but not all SRs, made more correct identifications and correct rejections than controls at all retention intervals, demonstrating that many SRs possess enhanced long-term face memory. This research adds to the knowledge of SR's skillsets, and enhances the case for the selection of SRs to identity critical roles—particularly policing.     

Power corrupts (or does it?): An examination of the boundary conditions of the antisocial effects of experienced power

One of the most common conclusions in the power literature is that when people feel powerful, they behave in selfish and antisocial ways. While this conclusion tends to permeate the literature, research also recognizes that there are factors that can mitigate the corrupting nature of power, and that the experience of power may also lead to more positive and prosocial outcomes. In this article, we review findings that illustrate how individual differences, the contexts in which people experience power, and their construal of power all help determine how powerful people will ultimately behave toward others. We then consider these findings in totality, and suggest that they may articulate a more complex conceptualization of power as it relates to social behaviors. Specifically, we suggest considering not only the amount of power one has but also focusing on the way individuals experience power may provide a way to reconcile the disparate findings in the social power literature. We argue that research should expand upon the possible dualistic nature of power, and how the existence of both positive and negative construals of power can influence behaviors.     

A contingent view of reactions to objective pay conditions: interdependence among pay structure characteristics and pay relative to internal and external referents

The authors studied the general proposition that because social comparisons are so central to how people react to pay, the effect of an important pay condition likely depends on a social pay comparison that is relevant to that condition. To investigate this, the authors used actual pay data on more than 2,000 public school teachers across more than 400 school districts and tested whether pay equity perceptions resulted from interactions among objective measures of structural (pay dispersion, entry-level pay, pay range maximum, external competitiveness) and individual (pay relative to internal referents, pay relative to external referents) pay conditions. Cross-level interactions indicated that pay relative to internal referents moderated how pay structure conditions related to pay equity perceptions. Additionally, within-level interactions indicated that the effect of employee standing in the external pay hierarchy depended on where one stood in the internal pay hierarchy; this dynamic emerged both for individual-level measures of current standing and for organization-level measures that suggested future standing.     

Managing job seekers' organizational image beliefs: the role of media richness and media credibility

In this article, the authors assessed job seekers' organizational image beliefs before and after they experienced 3 recruitment media. The authors examined whether perceptions of media richness and credibility were related to improvements in the correspondence between job seekers' image beliefs and firms' projected images. Both media richness and credibility perceptions were associated with correspondence between job seekers' image beliefs and firms' projected images. However, results revealed that richness and credibility perceptions were likely to enhance job seekers' initial beliefs about firms' images when their beliefs were positive but did not diminish job seekers' beliefs about firms' images when their initial impressions were too positive.     

Accessing semantic knowledge in dementia: evidence from a word definition task

We examine production of word definitions by people with probable Alzheimer's disease (pAD). In the first experiment, healthy young adults defined concrete, imageable nouns to provide a baseline of definitional ability. Analysis of these definitions identified the key defining features of each target item. In the second experiment, pAD participants and elderly controls produced definitions of the same items. In the third experiment, healthy young participants rated the adequacies of these definitions. Although as expected the pAD participants produced fewer good definitions than the other two groups, most of their responses still contained some relevant information. pAD definitions contained fewer pieces of information and the information they produced was more tangential to the primary concept than that provided by the young or elderly participants. We identify two possible explanations in semantic loss and metalinguistic impairment. We consider metalinguistic impairment to provide the more plausible explanation of pAD patients' definitional performance.
