This study attempted to determine the effects of alcohol, verbal provocation, and target strategy on male aggression toward female targets. Intoxicated and nonintoxicated male research participants competed with a female confederate in a reaction time task designed to measure aggression. Intoxicated participants responded more aggressively than did nonintoxicated participants. Verbal provocation had no effect on participants' aggressive response. Effects of target strategy and trial outcome lent support to a cognitive disorganization interpretation of the effect of alcohol on aggression.  相似文献

The long-term effects of a preschool intervention program for high-risk experimental children were assessed and compared to a high-risk placebo control group and low-risk normal controls. Seventy first-grade children were involved in this 2-year follow-up. The experimental treatment group was superior to that of the placebo control group at follow-up on the criteria measures of behavioral adjustment and achievement. The low-risk normal control group was significantly different from that of the placebo control groups, but generally not significantly different from that of the experimental groups, suggesting that the intervention had boosted the high-risk experimental treatment children to the point where their performance was comparable to that of children who had not experienced behavioral or learning difficulties.The study was supported by grants from the McGregor Fund and the Eloise and Richard Webber Foundation, and by the Detroit Public Schools, for which the authors express grateful appreciation. A version of this paper was presented at the Annual Meeting of the American Psychological Association, New York, September 1979.  相似文献

It is proved for the common factor model withr common factors that under certain condition s which maintain the distinctiveness of each common factor a given common factor will be determinate if there exists an unlimited number of variables in the model each having an absolute correlation with the factor greater than some arbitrarily small positive quantity.The author is indebted to R. P. McDonald for suggesting the proof of Guttman's determinantal equation for the squared multiple correlation in predicting a factor from the observed variables used in the parenthetical note.  相似文献

A characterization of stochastic independence in terms of association of random variables is given. The result is applied to yield a simple proof of the Sattath-Tversky inequality without continuity assumptions.  相似文献

The following comparisons between Freud's and Piaget's concepts are proposed: eros drive = constructive assimilation = direction toward the object in the sense of love for newness and otherness; death drive = constrictive assimilation = direction away from or destruction of the object out of fear for self to preserve the system. Eros and assimilation drive combine in the developing object and symbol formation to transform personal relations and knowledge. These psychological theories are further confirmed by evolutionary considerations about human social relations and by Macmurray's philosophy of personal relations as the primary function of reason.  相似文献

ABSTRACT The aim of this study was to test whether the concept of an altruistic personality was valid for first aiders who intervened to help the victims of a traffic accident. We derived a number of relevant personality variables that should be related to the willingness to administer first aid. These include locus of control, social responsibility, belief in a just world, empathy, and instrumentality. We obtained data from proven first aiders who had intervened after a traffic accident. Thirty-four of these first aiders were matched to respondents from a subject pool on the basis of sex, age, and socioeconomic status. In addition, the willingness of these respondents to offer help after a traffic accident was taken into account. Only people who indicated that they had witnessed an accident and had not helped were included in the control group. Multivariate analyses of variance and covariance indicated that proven first aiders deviated from the control group on several dimensions: They described themselves as more internal, believed more in a just world, and emphasized more social responsibility and empathy.  相似文献

Task dynamics corresponding to rhythmic movements emerge from interactions among dynamical resources composed of the musculature, the link segments, and the nervous and circulatory systems. This article investigated whether perturbations of interlimb coordination might be effect over circulatory and nervous elements. Stiffness of wrist-pendulums oscillated at a common tempo and at 180 degrees relative phase was perturbed through the use of tonic activity about an ankle. Left and right stiffnesses, the common period, and the phase relation all changed. Stiffnesses increased with ankle torque in proportion to the wrist's inertial load. Despite different changes in stiffness at the two wrists, isochrony was preserved. The stability was shown to be consistent with the proportionality of changes in stiffness to the inertial loads. The phase departed from antiphase in proportion to the asymmetry of inertial loads. The size of departures decreased with increasing ankle torque. An account was developed in terms of muscular, circulatory, and nervous functions.  相似文献
