Measurement of agency, communion, and emotional vulnerability with the Personal Attributes Questionnaire

Factor analytic studies of the 24-item Personal Attributes Questionnaire (Spence & Helmreich, 1978) have reported inconsistent results, and a previous confirmatory factor analysis (CFA) indicated inadequate fit for factors corresponding to Masculinity, Femininity, and Masculinity-Femininity scales. In this research, we used CFA in a college sample (N = 382) to evaluate the 3-factor model, and we revised scales by eliminating 6 misspecified items. The revised model fit well in another college sample (N = 230). We renamed the revised scales Agency, Communion, and Emotional Vulnerability. In relation to Five-factor theory, Emotional Vulnerability and Communion correlated well with Neuroticism and Agreeableness, respectively, and Agency had moderate correlations with Neuroticism, Extraversion, and Conscientiousness. Psychometric results in the context of current theory suggest that Agency (Masculinity) may not be a fully adequate measure of the agency construct.     

Spirituality,Anger, and Stress in Early Adolescents

The purpose of this study was to explore the relationship of spiritual beliefs and involvement with anger and stress in early adolescents. Early adolescents (n = 53) completed the Spiritual Involvement and Beliefs Scale (Hatch et al. 1998), the State-Trait Anger Expression Inventory (Spielberger 1999), and the Perceived Stress Scale (Cohen and Williamson 1988). Contrary to expectations, spirituality was significantly and positively related to anger and stress. Implications and possible explanations for the unanticipated findings in this study are discussed.     

Making Sense of the APA: A History of the Relationship Between Psychology and the Military

The American Psychological Association (APA) has been steadfast in its position that psychologists must have the right to participate in interrogations in U.S.-run illegal detention centers. One wonders why the APA is so resolute in this view especially in light of the opposition to involvement in these sites by all other relevant professional organizations. This paper offers an answer to this question by means of an exploration of the historical bond between American psychology and the military. It is demonstrated that the dramatic growth of psychology after World War II is attributable to resources supplied by the Department of Defense and the Central Intelligence Agency. It is argued that the historical and current dependency of psychology on the military for research funds as well as clinical training and treatment has resulted in a historical and current debt on the part of psychology to both of these organizations. This debt is repaid by an unquestioned endorsement of military policy, no matter how questionable its ethical or legal basis might be.     

Timing goals in bimanual coordination

Phase coupling between movement trajectories has been proposed as the basic mechanism of hand coordination in the production of bimanual rhythmic movements with a 1:2 frequency ratio. Here a central temporal coupling view is proposed as an alternative. Extending previous models of two-handed synchronic and alternate-hand tapping, we hypothesized that 1:2 tapping is performed under the control of a single internal timekeeper set at the frequency required for the fast hand. The fast hand is assumed to use every signal and the slow hand every other signal of the timekeeper, to produce actions coordinated in time. The model's predictions for the variance-covariance pattern of tap timing within and across hands were tested in an experiment that required tapping with both hands with 1:1 or 1:2 frequency ratio. The finger contact on the response plate was to be short or long, according to instruction. Prolonged finger contact entailed profound modifications in the movement trajectories but failed to modify the variance-covariance pattern of the tap timing. This pattern proved to conform to predictions under both the short and the long contact conditions, thus supporting the central temporal coupling hypothesis.     

What causes the spacing effect? Some effects of repetition,duration, and spacing on memory for pictures

Three experiments examined effects of the spacing of repetitions on memory for pictures. In Experiment I, the duration of the first presentation (P(1)) was manipulated, as was P(1)-P(2) spacing. The effect of spacing on judged frequency was independent of P(1) duration. In Experiment II, pictures were given M massed presentations just prior to the P(M)-P(M+1) spacing interval. The form of the spacing curve was independent of M. Neither experiment confirmed the prediction of "overhabituation," derived from the habituation-recovery explanation of the spacing effect. In Experiment III, subjects made both duration and frequency judgments. The duration judgment results were not consistent with the notion that subjects remember multiple massed presentations as single occurrences of especially long duration. Some evidence from Experiments I and III suggests that an interrupted stimulus is recognized better than one that is not interrupted-a finding that, if replicable, would support the habituation-recovery account of the spacing effect.     

Voluntary attention and the spacing effect

Three experiments were done to test the hypothesis that the spacing effect results from a voluntary decision by the subject to pay little attention to the second presentation (P₂) of an item when it occurs shortly after the first (P¹)- In all three experiments, the spacing of repetitions was varied. In Experiment I, allocation of attention was manipulated by pairing P₂ of some pictures with a signal that indicated high payoff for later retention. In Experiment II, attention was controlled more directly by requiring the subject, in one condition, to recite words aloud. In both experiments, the dependent variable was judged frequency. In neither experiment did the effect of the attention manipulation interact with that of the spacing of repetitions. In Experiment III, the number of eye fixations given a picture was taken to be a measure of attention. The number of fixations dropped from P₁ to P₂ to P₃, but was unaffected by the spacing of repetitions. The experiments provide no support for a voluntary attention explanation of the spacing effect.
