The Ethnic Mentor Undergraduate Program: A Brief Description and Preliminary Findings

The Ethnic Mentor Undergraduate (EMU) Program targets students from traditionally underrepresented ethnic backgrounds and aims at fostering skills and attitudes necessary to persist to graduation. Findings indicate that EMU protégés perform better than the university-wide average and that drop-out rates are reduced. Implications for mentoring programs are discussed.     

Metamemory,distinctiveness, and event-related potentials in recognition memory for faces

A neglected topic in metamemory research is the ability of subjects to predict their own recognition performance for faces. We investigated whether subjects can make such judgments of learning (JOL) for unfamiliar faces and whether JOLs relate to facial distinctiveness, a powerful determinant of face recognition. One group of subjects made JOLs, and a second group rated the same faces for distinctiveness; subsequently, both groups tried to recognize these faces among new faces. There was significant prospective metamemory for faces that appeared to be based on facial distinctiveness. Both prospective metamemory and distinctiveness ratings related to long-lasting effects in event-related brain potentials (ERPs), closely resembling an ERP component that predicted face recognition. Therefore, the brain processes underlying JOLs, distinctiveness, and recognition memory for faces appear to be intimately related.     

The need for an evolving concept of validity in industrial and personnel psychology: Psychometric, legal, and emerging issues

The Trinitarian view of validity (namely content, criterion-related, and construct) has dominated psychology for almost a half century. In industrial and personnel psychology especially, content and criterion-related (in particular) forms of validity have served as workhorses. Such a limited focus has lead to a stagnation of the area and the inability to incorporate more theory into the research and practice of personnel psychology. Therefore, we review the evolution of the concept of validity in the psychology discipline, with a particular emphasis on industrial and personnel psychology. We then review the legal and statutory history within industrial and personnel psychology that has helped to shape the concept of validity over the years. Finally, we examine some emerging trends in industrial and personnel psychology, including the issue of graduate training, which may have important consequences on how we conceptualize validity in the future in both our research and practice of personnel psychology.     

Psychometric properties of the children's atypical development scale

The Children's Atypical Development Scale (CADS) is a 53-item rating scale designed to measure unusual behaviors in children. Principal-factor analysis on a clinic-referred and pediatric sample of 474 children resulted in a four-factor solution: Communication Deficits, Lability, Social Relatedness Deficits, and Preoccupation. The CADS is internally consistent and has adequate temporal stability. CADS factor scores were differentially associated with parent and teacher rating scales, IQ, and Continuous Performance Test errors. The scale shows promise as a clinical and research tool for assessing atypical behaviors associated with pervasive developmental disorder and other neurobehavioral disorders.This research was supported in part by a grant from the Smart Family Foundation. The authors are grateful to James P. O'Donnell, Catherine Lord, and Frank A. Zelko for their comments on an earlier draft.     

The Givenness of Other People: On Singularity and Empathy in Husserl

Human Studies - Other people figure in our experience of the world; they strike us as unique and genuinely other. This paper explores whether a Husserlian account of empathy as the way in which we...     

Delinquent peer group formation: evidence of a gene x environment correlation

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N= 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delinquent peer affiliation for male adolescents from high-risk environments (beta range = .13-.14) despite controlling for delinquent involvement, self-control, and drug and alcohol use. The authors discuss the importance of using a biosocial framework to examine issues related to adolescent development.     

A reliability generalization study of coefficient alpha for the UCLA loneliness scale

Loneliness is a psychological construct that has been reported in a variety of populations and associated with a number of other negative psychological problems. This study was an examination of coefficient alpha of a prominent measure of loneliness: the University of California, Los Angeles (UCLA) Loneliness Scale (Russell, Peplau, & Cutrona, 1980; Russell, 1996). We utilized reliability generalization to provide an aggregate estimate of the reliability of the scale over time and in a variety of populations as well as to assess and identify sampling and demographic characteristics associated with variability in coefficient alpha. Of the 213 studies examined, 80 had reported alpha estimates, and we used them in this analysis. We discuss conditions associated with variability in coefficient alpha along with pertinent implications for practice and future research.     

Probe-specific proportion task repetition effects on switching costs

In two experiments, participants were presented with successive presentations of animal names (e.g., GORILLA, WHALE)--a prime display followed by a probe display. In response to each display, participants judged either the typical habitat or the relative size of those animals, repeating the same task in response to both displays on half of the experimental trials and switching from one task to the other on the other half of trials. Our results demonstrate that switch costs can be reduced when either the probe's identity or its location is predictive of a change in task. This result establishes that the presentation of a stimulus can serve as a rapid cue for facilitating a switch in task, independent of processes occurring both at the time of the prime task and during the intervening period between the prime and probe tasks. We discuss the implications of these results for prevailing explanations of task switching costs.     

Comparing Brief and Extended Wait-Time During Small Group Instruction for Children with Challenging Behavior

This preliminary study compared brief (1 s) and extended (4 s) wait-time on response opportunities, academic responses, accuracy, and disruptive behavior of two children with challenging behavior during small group instruction. Brief wait-time increased children’s response opportunities, academic responses, and accuracy in comparison to extended wait-time. Though variable, brief wait-time also decreased children’s disruptive behavior. Findings differ from previous research, which found performance improvements with extended wait-time for children with moderate to profound cognitive disabilities. Limitations of the study and future research suggestions are discussed.     

Anxiety, depressed mood, self-esteem, and traumatic stress symptoms among distant witnesses of the 9/11 terrorist attacks: transitory responses and psychological resilience

Posttraumatic stress related to the September 11, 2001 terrorist attacks and general psychological distress were examined in six cohorts of college students (N=5412) enrolled at an American public university between Spring 2000 and Fall 2002 some 2,500 miles from New York. Consistent with data from Schuster et al.'s (2001) national survey, which used a very low threshold criterion, our findings revealed that 44% of women and 32% of men experienced at least one symptom of posttraumatic stress 6-17 days after the attacks. In contrast to these results, depression levels showed only small differences, and self-esteem and trait anxiety showed no changes. Findings indicate that 9/11-related stress responses among distant witnesses were very mild, transitory and focused in scope, suggesting resilience with respect to broader psychological and psychopathological reactions. Findings are discussed with respect to the role of physical and psychological proximity on the reactions to traumatic events in the general population.
