Racial Bias and the MCMI

We studied the scores obtained on the Millon Clinical Multiaxial Inventory (MCMI) by Black and White male psychiatric inpatients to determine the presence or absence of racial bias. In predicting psychopathology for the two races, comparisons of MCMI performance indicated significant differences for all diagnoses except the personality disorders. The subjects were then matched into two groups of 209 patients each, according to DSM-111 psychiatric diagnoses. The data were analyzed at the item, scale, and structural levels. At the item level, application of the Mantel-Haenszel Procedure revealed that 45 of the 175 items of the inventory were answered significantly different by the two racial groups. Because this number was higher than what could be expected by chance, the finding suggested possible deficiencies in terms of the culture-fairness of the items used in the test. At the scale level, an analysis of variance (ANOVA) demonstrated that the scores obtained by the Black and White groups were significantly different in 9 of the 20 scales (Histrionic, Narcissistic, Antisocial, Paraphrenia, Hypomania, Dysthyrnia, Alcohol Abuse, Drug Abuse, and Psychotic Delusion). With the exception of the Dysthymic scale, all of the differences were in the direction of the Blacks obtaining a higher score than the Whites. At the structural level, however, a principal components factor analysis performed on each group resulted in factor structures that looked identical.     

The impact of achievement goal states on working memory

The present study examines the influence of achievement goal states on working memory under varying executive load. Seventy-six undergraduate students were randomly assigned to either a mastery-approach condition (goal was to develop self-referential competence), a performance-approach condition (goal was to demonstrate normative competence) or a control condition (no goal assigned) prior to completing the N-Back working memory task. Analyses revealed achievement goal effects on working memory under high executive load (3-back) but not under the less demanding loads (1-back, 2-back). Under high load, pursuit of a performance-approach goal resulted in poorer working memory processing than pursuit of a mastery-approach goal or no-goal control. Findings are unlikely to be confounded by cognitive ability, working memory capacity or state-anxiety. Contributions to the motivation–cognition interface and suggestions for future research are discussed.     

Sub‐threshold autism traits: The role of trait emotional intelligence and cognitive flexibility

Theory and research suggests that features of autism are not restricted to individuals diagnosed with autism spectrum disorders (ASDs), and that autism‐like traits vary throughout the general population at lower severities. The present research first investigated the relationship of autism traits with trait emotional intelligence and empathy in a sample of 163 adults aged between 18 and 51 years (44% male). It then examined performance on a set of tasks assessing social cognition and cognitive flexibility in 69 participants with either high or low scores on ASD traits. Results confirm that there is pronounced variation within the general population relating to ASD traits, which reflect similar (though less severe) social‐cognitive and emotional features to those observed in ASDs.
