Handedness and depression in university students: a sex by handedness interaction

Previous research has indicated that there is an increased incidence of left-handedness in samples of depressed individuals. We administered the Beck Depression Inventory (BDI) to a sample of 541 undergraduate students. Left-handed males showed significant elevation of BDI scores. It is unlikely that this result is due to decreased right hemisphere activity or sex-role conflicts. However, one possibility is that known differences in male steroid hormones levels between right- and left-handers contributed to this effect. Press     

Parental marital status and adolescents' health-risk behavior

This article reports the results of a questionnaire survey of a representative random sample of all the in-school Francophone adolescents of Montreal. The sample size was 4,539 and included adolescents from legally intact homes, separated/divorced homes, and homes in which a parent was decreased. Health-risk behavioral indicators were smoking (how many cigarettes a day), fastening of car seat belts, and intemperate drinking. Adolescents who lived in intact families engaged less in health-risk behavior than the other adolescents, especially those from separated/divorced families. The results for adolescents from widowed families were mixed. Several mutually complementary explanations are presented.     

Actual Memory Ability Significantly Predicts Self-Evaluations of Memory

A number of researchers have suggested that confidence in one's memory is extremely flexible and that self-evaluations may actually reflect the difficulty of the memory task - rather than one's actual memory skill. This study examined this effect and related confidence in one's memory to actual memory skill, as measured by standardized neuropsychological tests of memory. We found that, indeed, confidence in one's memory can be altered. However, we observed that the best predictor of self-evaluation of memory was, in fact, actual memory skill as measured by standardized tests. We suggest that self-evaluation of memory and confidence in one's memory accurately reflects memory skill,although this evaluation can be slightly affected by the difficulty with which the memory is retrieved.

Patterns of Thinking in Militant Extremism

ABSTRACT— Recurrent features of the thinking pattern (or mind-set) of violent militant extremists are delineated, discussed, and related to previous research and theory. We examined extremist groups from a diverse range of continents, cultures, and political and religious orientations. We compared statements by (and, to some degree, statements about) these groups and formulated 16 themes common to the militant-extremist mind-set. Among these themes are perceptions of a crisis involving violations of posited sacred values, along with justifications for the use of violence to remediate such problems. There are indications that such themes are not infrequent in the general population. For example, research participants failed to strongly disassociate themselves from the sentiments and framings found in the fanatical items, which undercuts the notion that militant-extremist thinking represents bizarre ideation. Militant-extremist thinking appears to represent a major, aggressive form of fanaticism affected by both dispositional and situational factors. Key themes in this thinking pattern might fit together to construct a potentially compelling narrative, which may be a key part of the ideological appeal of salient militant-extremist groups.     

Before the measurement of prejudice: Early psychological and sociological papers on prejudice

Given its renown, many psychologists and sociologists likely consider the publication of Gordon Allport's ( 1954 / 1979 ) seminal book The Nature of Prejudice as the inauguration of the psychological study of prejudice. However, we have uncovered rarely‐cited, published papers (starting in 1830) that provide a wealth of speculation on prejudice even before psychologists/sociologists attempted to measure it (circa 1925). Thus, this paper intends to discuss early published work on prejudice in psychology and sociology by focusing on three key questions: a) when did psychologists/sociologists recognize prejudice as a psychological phenomenon, b) when did psychologists/sociologists recognize prejudice as a phenomenon in need of study, and c) what were the historical and personal conditions that gave rise to the interest in prejudice? In short, the seeds of prejudice research were maturing for some time before Allport's seminal book and the first attitudinal studies on prejudice, although these earlier works are seldom cited. © 2010 Wiley Periodicals, Inc.     

Openness versus intellect: Much ado about nothing?

McCrae (1990) has argued that Openness to Experience is a fundamental dimension of personality that is not well represented among English-language trait adjectives. Presumably, then, studies of personality adjectives will inevitably fail to capture at least one fundamental personality dimension. I argue that the language does contain many adjectives referring to Openness, and that recent studies of the language of personality reveal a large factor clearly related to both Openness and Intellect. These studies support both the Openness construct and the questionnaire version of the five basic factors. Lexical and questionnaire methods appear to converge on a single structural framework for basic personality traits.
