The objective of the study reported here was to explore the relationship of Graduate Record Examinations (GRE) General Test scores to selected personality traits--conscientiousness, rationality, ingenuity, quickness, creativity, and depth. A sample of 342 GRE test takers completed short personality inventory scales for each trait. Analyses…

This paper focuses on Spearman's law of diminishing returns which states that correlations between IQ tests decrease as the intellectual efficiency increases. In the present study, data from the national standardization sample of a French intelligence scale for children aged 4 to 9 years (Echelles Differentielles d'Efficiences Intellectuelles,…

This article presents a brief overview of existing research on the effects of exposure to violent video games. An updated meta-analysis reveals that exposure to violent video games is significantly linked to increases in aggressive behaviour, aggressive cognition, aggressive affect, and cardiovascular arousal, and to decreases in helping…

The effects of appetitive controllability on behavioral and cortisol reactivity to novelty in 12 infant rhesus monkeys were studied. Surrogate-peer-reared infants had homecage access to food treats contingently via lever pressing ("master") or noncontingently ("yoked") for 12 weeks from postnatal month 2. Masters lever-pressed more, but did not…

Objectified body consciousness (OBC)--the tendency to view oneself as an object to be looked at and evaluated by others--has received recent attention as a possible vulnerability factor for depression and disordered eating. Although OBC generally is discussed in developmental terms, extant research has examined primarily the experiences of…

This study extended research on prejudice against lesbian and gay (LG) persons by examining theoretically grounded links between intrapersonal and interpersonal manifestations of such prejudice. On the basis of G. A. Kelly's (1955/1991a, 1955/1991b) conceptualization of threat, the authors operationalized intrapersonal homophobia, or LG threat, as…

In their comment on K. Rothermund and D. Wentura, A. G. Greenwald, B. A. Nosek, M. R. Banaji, and K. C. Klauer agreed that salience asymmetries can be a source of Implicit Association Test (IAT) effects. The authors applaud this conclusion but point to problems with the other points that Greenwald et al. made. The authors have difficulties…

Emotional arousal can both enhance and impair memory. Considering that both emotional memory and trait anxiety (TA) have been associated with adrenergic activity, the authors investigated whether there is an association between 2 opposite emotional memory biases and the TA. The authors used a procedure recently put forward by B. A. Strange, R.…

Variables that have been coarsely categorized into a small number of ordered categories are often modeled as outcome variables in psychological research. The authors employ a Monte Carlo study to investigate the effects of this coarse categorization of dependent variables on power to detect true effects using three classes of regression models:…

The present study examined the relationships between two measures of career readiness and difficulties--the Career Thoughts Inventory (CTI) and the Career Decision-Making Difficulties Questionnaire (CDDQ)--as well as the relations between these measures and the individual's degree of decidedness regarding his or her career plans. A total of 192…

In this study, the precision of subscale score estimates was evaluated when out-of-scale information was incorporated. Procedures that incorporated out-of-scale information and only information within a subscale were compared through a series of simulations. It was revealed that more information (i.e., more precision) was always provided for…

This article studies the ordinal reliability of (total) test scores. This study is based on a classical-type linear model of observed score (X), true score (T), and random error (E). Based on the idea of Kendall's tau-a coefficient, a measure of ordinal reliability for small-examinee populations is developed. This measure is extended to large…

Though studies have been conducted to find out the effect of unemployment on credit enrollment in community colleges, none have been done to find the effect of unemployment on non-credit enrollment. The present study explores the following question: "When the economy is on a downward curve, does non-credit enrollment decrease and credit…

Protein synthesis-dependent late phase of LTP (L-LTP) is typically induced by repeated high-frequency stimulation (HFS). This form of L-LTP is reduced in the aged animal and is positively correlated with age-related memory loss. Here we report a novel form of protein synthesis-dependent late phase of LTP in the CA1 region of hippocampus induced by…

Much recent research on mechanisms of learning and memory focuses on the role of heterosynaptic neuromodulatory signaling. Such neuromodulation appears to stabilize Hebbian synaptic changes underlying associative learning, thereby extending memory. Previous comparisons of three related sea-hares (Mollusca, Opisthobranchia) uncovered interspecific…
