Ethnic group differences in measures of job performance: a new meta-analysis

The authors conducted a new meta-analysis of ethnic group differences in job performance. Given a substantially increased set of data as compared with earlier analyses, the authors were able to conduct analyses of Black-White differences within more homogeneous categories of job performance and to reexamine findings on objective versus subjective measurement. Contrary to one perspective sometimes adopted in the field, objective measures are associated with very similar, if not somewhat larger, standardized ethnic group differences (ds) than subjective measures across a variety of indicators. This trend was consistent across quality, quantity, and absenteeism measures. Further, work samples and job knowledge tests are associated with larger ds than performance ratings or measures of absenteeism. Analysis of Hispanic-White standardized differences shows that they are generally lower than Black-White differences in several categories.     

Blushing and physiological arousability in social phobia

Blushing is the most prominent symptom of social phobia, and fear perception of visible anxiety symptoms is an important component of cognitive behavioral models of social phobia. However, it is not clear how physiological and psychological aspects of blushing and other somatic symptoms are linked in this disorder. The authors tested whether social situations trigger different facial blood volume changes (blushing) between social phobic persons with and without primary complaint of blushing and control participants. Thirty social phobic persons. 15 of whom were especially concerned about blushing, and 14 control participants were assessed while watching an embarrassing videotape, holding a conversation, and giving a talk. Only when watching the video did the social phobic persons blush more than controls blushed. Social phobic persons who complained of blushing did not blush more intensely than did social phobic persons without blushing complaints but had higher heart rates, possibly reflecting higher arousability of this subgroup.     

Identification and meta-analytic assessment of psychological constructs measured in employment interviews

There has been a growing interest in understanding what constructs are assessed in the employment interview and the properties of those assessments. To address these issues, the authors developed a comprehensive taxonomy of 7 types of constructs that the interview could assess. Analysis of 338 ratings from 47 actual interview studies indicated that basic personality and applied social skills were the most frequently rated constructs in this taxonomy, followed by mental capability and job knowledge and skills. Further analysis suggested that high- and low-structure interviews tend to focus on different constructs. Taking both frequency and validity results into consideration, the findings suggest that at least part of the reason why structured interviews tend to have higher validity is because they focus more on constructs that have a stronger relationship with job performance. Limitations and directions for future research are discussed.     

Risk propensity differences between entrepreneurs and managers: a meta-analytic review

Research examining the relative risk-taking propensities of entrepreneurs and managers has produced conflicting findings and no consensus, posing an impediment to theory development. To overcome the limitations of narrative reviews, the authors used psychometric meta-analysis to mathematically cumulate the literature concerning risk propensity differences between entrepreneurs and managers. Results indicate that the risk propensity of entrepreneurs is greater than that of managers. Moreover, there are larger differences between entrepreneurs whose primary goal is venture growth versus those whose focus is on producing family income. Results also underscore the importance of precise construct definitions and rigorous measurement.     

Latent growth models of the longitudinal effects of dementia caregiving: a comparison of African American and White family caregivers

Self-report measures of depression, physical health symptoms, and life satisfaction were collected over a 2-year period from 197 family caregivers of dementia patients and 218 noncaregivers (controls). Latent growth models were used to compare changes across time for African American and White caregivers, with gender, age, and socioeconomic status serving as covariates. Results indicated that White caregivers sustained higher levels of elevated depression and decreasing life satisfaction over time compared with African American caregivers. Both groups of caregivers reported increases in physical symptoms over time. These results indicate worsening difficulties over time for many White caregivers. African American caregivers show more resilience on measures of depression and life satisfaction but are still vulnerable to increases in physical symptoms over time. Implications for additional research and clinical intervention are discussed.     

The Role of Unconditional Parental Regard in Autonomy‐Supportive Parenting

Two studies explored the role of parents’ unconditional positive regard (UCPR) as perceived by adolescents and young adults in promoting the effectiveness of specific parenting practices that may support offspring's academic autonomous motivation. Study 1 tested the hypothesis that UCPR predicts rationale‐giving and choice‐provision practices and, at the same time, moderates their relations with adolescents’ autonomous motivation. Study 2 replicated the association between UCPR and the parental practices, and further explored the role of parents’ authenticity as an antecedent of UCPR and parental autonomy support. Study 1 included 125 adolescents and Study 2 considered 128 college‐students and their mothers. The offspring reported on their perceptions of their mothers and on their autonomous motivation, and the mothers reported on their sense of authenticity. Both studies found consistent associations between UCPR and parenting practices that may support autonomous motivation. Moreover, Study 1 demonstrated that the rationale giving and choice provision were more strongly related to adolescents’ autonomous motivation when adolescents perceived mothers as high on UCPR. Finally, Study 2 demonstrated that mothers’ authenticity predicted UCPR, which in turn was related to autonomy‐supportive parenting. Findings support the assumption that parents’ autonomy‐supportive practices are more effective when accompanied by UCPR.     

Power and errors in adverse impact indices

Adverse impact indices are intended to detect potentially discriminatory employment practices, and although the number of such indices continues to increase, with a few exceptions, little is known about the comparative performance of those indices under various conditions. We examined the performance of eight such indices, including statistical significance tests, ad hoc “practical” tests proposed by the courts, and effect size measures. The power of these indices was examined under various levels of adverse impact, applicant pool sizes, and selection ratios. Although no index performed well in all circumstances, typically, Fisher’s exact test and the Z test for proportions (with correction for continuity) performed adequately most often. However, in some conditions, these indices were outperformed by some of the “practical” tests.     

Awareness of memory task impairment versus everyday memory difficulties in dementia

The study investigated different types of awareness of memory dysfunction in dementia, specifically judgements concerning memory task performance or appraisal of everyday memory functioning and also exploring the neuropsychological correlates of such awareness. This was investigated in 76 people with dementia, comprising 46 patients with Alzheimer's disease (AD) and 30 patients with vascular dementia (VaD). The Memory Awareness Rating Scale (Clare et al., 2002, Neuropsychol Rehabil, 12, 341–362) was used, which includes an Objective‐Judgement Discrepancy (OJD) technique involving comparison of subjective evaluation of performance on specific memory tasks with actual performance, and a Subjective Rating Discrepancy (SRD) technique, which compares self versus informant judgement of everyday memory function. The AD and VaD groups showed lower awareness than a normal control group for both types of measures, the AD group showing less awareness than the VaD group on the OJD measure. Regression analyses supported associations for both groups between memory impairment and the OJD measure and between naming impairment and the SRD measure. The findings are discussed in terms of neurocognitive theories accounting for loss of awareness in dementia.     

Jewish Courts in Medieval England

Basing their conclusions on Latin documents, historians have painted the Jewish courts of medieval England as limited and haphazard affairs, their jurisdiction limited mostly to family law. They have also assumed that rabbinic courts ceased their activity in England after 1242. Hebrew rabbinic sources from the same period—some of which have never been published—provide more detailed information. These sources describe several professional courts staffed by learned scholars and adjudicating a range of legal issues. These courts existed throughout the thirteenth century—until the Expulsion of 1290—and included some of the leading rabbis in medieval England: Benjamin of Cambridge, Moses of London, and Moses’s son Elijah Menahem. The London court of Rabbi Elijah Menahem in particular possessed significant powers and utilized Elijah’s royal connections to enforce its rulings. Besides correcting the scholarly perception of rabbinic courts in medieval England, this article demonstrates how crucially important rabbinic texts and responsa are for historians as a source alongside other types of medieval documentation.     

The Theory of Planned Behavior: Some Measurement Issues Concerning Belief-Based Variables

The theory of planned behavior presents clear operational definitions of attitudes, subjective norm, perceived behavioral control, and each of their corresponding belief-based measures. Theoretically, the direct and indirect measures of a given construct must be closely correlated. Empirical results, however, indicate that this is not always the case. In the present study, 2 of the factors that could be responsible for this situation-namely, the scaling of the variables defining each belief-based construct and the adequacy of using an expectancy-value model within the belief-based measures-were verified among a data set of 16 studies concerned with the application of the theory of planned behavior to the field of health. The results indicate that the scaling method used affected the correlation coefficients between indirect and direct measures. However, the face validity of these scaling methods must be demonstrated. The results also support the idea that, in most cases, using the expectancy-value model is no better than using only one arm of the belief-based measure.
