Creative thinking abilities and hemispheric asymmetry in schizotypal college students

Two groups of college students that scored high (N=25) and low (N=60) on a schizotypal personality index based on the Perceptual Aberration, Magical Thinking, and Schizotypal Personality Scales, were tested for hemisphericity using a dichotic listening task and completed the Torrance Test of Creative Thinking. The schizotypy scales correlated with high scores on the nonverbal portion of the creativity tests and with a left ear preference to dichotically presented verbal stimuli. The Torrance Test of Creative Thinking did not correlate, however, with hemispheric asymmetry. These results clarify the relationship between schizotypy and creating thinking abilities but fail in establishing the role of hemispheric asymmetry in the production of creative thinking ideas. This article is based on a portion of the first author’s dissertation at Wayne State University.     

The Relationship Between Typical and Maximum Performance: A Meta-Analytic Examination

This study's purpose was to meta-analytically estimate the magnitude of the relationship between typical and maximum job performance to determine if this distinction deserves greater attention. We also tested several moderators including three associated with the temporal boundaries of this relationship and examined theoretical antecedents of typical and maximum performance (ability, motivation, and personality). This meta-analysis revealed a moderate typical–maximum performance association (ρ = .42), suggesting that a meaningful distinction does exist. Although the examined temporal moderators did not meaningfully affect the typical–maximum performance relationship, task complexity, type of performance measure, and study setting were significant moderators. Antecedent analyses confirmed that both ability and Openness to Experience are more strongly related to maximum than typical performance. The implications of these findings are discussed.     

Evidence affects hypothesis judgments more if accumulated gradually than if presented instantaneously

In a hypothesis comparison task involving quantifiable evidence, we investigated whether judgments of relative probability were affected by gradual evidence accumulation and by making a series of revised ratings, rather than a single final one. Each trial of our task required participants to rate the probability that a focal hypothesis, rather than its alternative, was correct. We manipulated (1) the strength of evidence supporting the focal hypothesis, (2) the strength of evidence supporting its alternative, and (3) whether that evidence was presented in three sequential portions (gradually accumulated evidence condition) or, instead, was all presented instantaneously (control condition). In a second experiment, we also manipulated (4) the number of successive ratings made within a trial with gradually accumulated evidence. Regardless of how many ratings were made per trial, gradual evidence accumulation increased the effects of evidence strength on ratings of relative probability.     

Measuring Employee Engagement During a Financial Downturn: Business Imperative or Nuisance?

In this article, we emphasize that measuring workforce attitudes is a business imperative—including during an economic downturn or crisis. After reviewing the concept of employee engagement we draw upon recent real-world examples and data across a variety of organizations and argue for the business value of an engaged workforce. We offer practical applications for HR managers, including providing guidance on the types of questions that should be asked in an employee survey and focusing on those that result in the most actionable feedback. We conclude the paper by laying out an agenda for future research aimed at helping bridge the academic-practitioner divide.     

Prenatal maternal predictors of cognitive and emotional delays in children of adolescent mothers

The present study examined relationships among prenatal characteristics of 121 adolescent mothers-including cognitive readiness for parenting, intelligence, social support, and personal adjustment-and intellectual-linguistic development, social-emotional functioning, and adaptive behavior in their children at three years of age. Only 28% of the children scored within normal ranges on all three types of outcomes. Intellectual and linguistic delays were predicted best by prenatal measures of maternal Performance IQ and social support from extended family. Socioemotional problems were predicted best by maternal internalizing problems and social support from partner and friends. Adaptive behavior was associated with parenting style. Implications for the early identification of high-risk children--and associated intervention programs--are discussed.     

Sensitivity of the Wisconsin Card Sorting Test (64-Card Version) versus the Tower of London (Drexel Version) for detecting executive dysfunction in children with epilepsy

Executive function deficits are common in children and adolescents with epilepsy. Though the Wisconsin Card Sorting Task (WCST) is often considered the “gold standard” for executive function assessment, its sensitivity—particularly in the case of the 64-card version (WCST-64)—is insufficiently established in pediatric samples, including children and adolescents with epilepsy. The present investigation assesses the sensitivity of the WCST-64 in children and adolescents with epilepsy in comparison to another measure: the Tower of London – Drexel Version (TOL-DX). A total of 88 consecutively referred children and adolescents with epilepsy were administered both the WCST-64 and TOL-DX as part of a comprehensive neuropsychological evaluation. The sensitivity of WCST-64 and TOL-DX variables were established and relations with epilepsy severity measures and other executive function measures were assessed. Of the WCST-64 variables, Perseverative Responses is the most sensitive, but detected executive function impairment in only 19% of this clinically referred sample; in contrast, the TOL-DX Rule Violations detected executive function impairment in half of the sample. Further, TOL-DX performances are more strongly related to epilepsy severity variables and other executive function measures in comparison to the WCST-64. Despite its popularity amongst clinicians, the WCST-64 is not as sensitive to executive dysfunction in comparison to other measures of comparable administration time, such as the TOL-DX.     

An empirical investigation of dispositional antecedents and performance-related outcomes of credit scores

Many organizations use credit scores as an employment screening tool, but little is known about the legitimacy of such practices. To address this important gap, the reported research conceptualized credit scores as a biographical measure of financial responsibility and investigated dispositional antecedents and performance-related outcomes. Using personality data collected from employees, objective credit scores obtained from the Fair Isaac Corporation, and performance data provided by supervisors, we found conscientiousness to be positively related and agreeableness to be negatively related to credit scores. Results also indicate significant relationships between credit scores and task performance and organizational citizenship behaviors. Credit scores did not, however, predict workplace deviance. Implications for organizations currently using or planning to use credit scores as part of the screening process are discussed.     

Implicit Coping Styles as a Predictor of Aggression

Research exploring potential antecedents of aggression provides contradictory results, with some data relating adaptive coping styles with high aggression and other studies finding the inverse. Clarification of these relationships could improve intervention and prevention strategies. This study investigated relationships between aggression and 3 coping styles (adaptive, neurotic, and maladaptive) via cross-sectional correlational methodology (N = 355). Data supported both hypotheses: First, the use of less adaptive coping styles predicted higher levels of aggression; second, this relationship held true for both cognitive (anger and hostility) and overt (physical and verbal) expressions of aggression. Results indicate that maladaptive coping significantly predicts aggression. Implications include potential prediction and prevention strategies to reduce the probability of higher risk individuals exhibiting aggression.     

The Relationship between Two Measures of the Tendency to Give Socially Desirable Responses

Two measures of the tendency to endorse socially desirable (SD) responses were obtained for 137 Ss. The first was from Edwards' SD scale and the second from an experimental scale consisting of responses in the P-F Study for which ratings of SD were available. There was no significant correlation between these measures. A second group of 94 Ss then rated a sample of 10 items each from the 2 scales on six bipolar dimensions. It is concluded that there is agreement across Ss as to the connotations of a socially desirable response but that personality type statements differ from responses in social situations in respect to the measure each provides of a person's tendency to endorse SD responses.
