Performances on Rey Auditory Verbal Learning Test and Rey Complex Figure Test in a healthy, elderly Danish sample--reference data and validity issues

This study presents Danish data for Rey Auditory Verbal Learning Test (RAVLT) and Rey Complex Figure Test (RCFT) from 100 subjects aged 60-87 years. Education and estimated verbal intelligence (DART score) had a significant impact on the RAVLT trial 1-5 score but not on other RAVLT measures. The RCFT copy score was significantly related to age and the DART score. On RCFT recall a highly significant difference was found between persons who could make a faultless copy and persons with incomplete copy performance. Thus, this study presents separate data for RCFT recall scores according to the subjects' copying performance (in separate tables for age and education groups). For all measures on both RAVLT and RCFT wide distributions of scores were found and the impact of this broad score range on the tests' discriminative validity is discussed. RAVLT performances for elderly were similar to previous published meta-norms, but the included sample of elderly Danes performed better on RCFT (copy and recall) than elderly from the United States.     

Measuring and Reducing Religious Bias in Post‐Conflict Zones: Evidence from Côte d'Ivoire

This article explores how religious bias, once it has been cultivated through politicization and violence, can be reduced. Using foundations from social identity theory and superordinate goal theory, I develop post‐conflict bias reduction strategies that include competing types of superordinate messages, economic and theological, as well as different sources of those messages. To test these strategies, I use video‐based information treatments coupled with Implicit Association Tests in Bouaké, Côte d'Ivoire. The experimental findings point to three conclusions. First, implicit Muslim‐Christian bias in the study area remains high. Second, Christians in the study tend to be more biased against Muslims than Muslims are against Christians. Third, the effectiveness of treatments depends on the subjects who receive those treatments: theological messages are most effective in reducing bias among Muslims, regardless of their source, and strategies that rely on political leaders to deliver messages perform best among Christians, regardless of the content.     

The detection and influence of problematic item content in ability tests: An examination of sensitivity review practices for personnel selection test development

In organizational and educational practices, sensitivity reviews are commonly advocated techniques for reducing test bias and enhancing fairness. In the present paper, results from two studies are reported which investigate how effective individuals are at detecting problematic test content and the influence such content has on important testing outcomes. In Study 1, signal detection analyses are used to examine the role of individual differences in the identification of insensitive test items, while Study 2 investigates the extent to which insensitivity differentially influences item performance and reactions. Results revealed small but significant differences in the overall accuracy and response tendencies of student test reviewers on the basis of demographics and key individual differences variables. Contrary to predictions however, problematic items did not exhibit differential item functioning across sex nor did their presence engender negative test taker reactions. Implications and suggestions for future research and sensitivity review practices are discussed.     

Mental and Motor Switching in Parkinson's Disease

Switching difficulties in Parkinson's disease (PD) are expressed in both mental and motor tasks. The authors of the present study investigated whether those deficits coexist in the same patient and are positively correlated. They tested 8 nondemented PD patients and 6 age-matched control participants by using the modified Wisconsin Card Sorting Test and a motor switching paradigm that is based on the task of reaching toward visual targets, the location of which could unexpectedly be altered within the reaction time. In both mental and motor tasks, patients performed significantly worse than controls. There were no significant correlations between the two types of pathology in individual patients. Mental and motor switching deteriorate in PD patients, but the deficits are not necessarily of parallel severity.
