Harries and Stadler (1988) observed only a positive linear trend, with no curvilinear relationship, between heat and violence in their 1980–81 Dallas field data. When Cotton (1986) observed similar trends in his data, we noted that in fact the variance in violence increases with temperature (Bell & Fusco, 1986). We report here similar statistically significant heteroscedasticity in the Harries and Stadler data. We propose that both aggressive and escape tendencies increase with high ambient temperatures, such that in some circumstances aggression will decline under very hot and uncomfortable conditions. We conclude that the negative affect escape model of the temperature-aggression relationship is neither dead cold nor hot and bothered. 相似文献

Habituation to mother's face in naturally occurring en face social interactions and to a single object in naturally occurring solitary play was studied in American and Japanese infants. Habituation was observed in both conditions in both samples, and home habituation data paralleled analogous laboratory habituation data both quantitatively and qualitatively. 相似文献

Summary We examined 5-month-old infants' sensitivity to audiovisually coherent and incoherent events. A person speaking and an automobile with engine running were filmed approaching and receding with corresponding (coherent) soundtracks. Infants were tested with a habituation paradigm in which they observed coherent or incoherent films, involving, respectively, acoustical radial motion in the direction seen or opposite to the direction seen. Infants habituated to both person and car films, but coherent events uniformly yielded more rapid habituation than did incoherent ones. In addition, infants treated silent events more like audiovisual coherence than like incoherence. Infants habituated more to cars than to people, suggesting that a speaking person may especially maintain infant attention. 相似文献

A comparison of objective classroom measures and teacher ratings of attention deficit disorder 总被引:4,自引:0,他引:4
Marc S. Atkins William E. Pelham Mark H. Licht 《Journal of abnormal child psychology》1985,13(1):155-167
Children identified as Attention Deficit Disorder (ADD) on the basis of teacher ratings using the SNAP Rating Scale were compared to non- ADD children on objective classroom measures including observations of classroom behavior, examination of the organization of children's desks, and scoring of daily academic work. Analyses provided some support for the ability of the objective measures to differentiate between teacheridentified ADD and non-ADD children, though there was considerable overlap on the distributions of most variables between groups. Six measures chosen by a discriminant analysis combined to predict teacher ratings in 83% of the cases. The inclusion of academic, observational, and desk measures in the discriminant function indicates the importance of a multivariate assessment of this construct.Portions of this paper were presented as part of a symposium, W. Pelham (Chair),Identification and diagnosis of children with attention deficit disorder/hyperactivity, at the meeting of the American Psychological Association, Washington, D.C., August 1982. We thank the director, Dr. Edward Vertuno, and the teachers and staff of the Florida State University Developmental Research School for their cooperation and efforts throughout this study. In addition, we wish to thank our observers, Susan Friedan and Stephanie Martinez, whose patience, intelligence, and dedicated effort made this study possible; Denise Gammonsly, for work on the development of the Desk Checks, and Dr. Janet Belew, whose contributions during the early phase of this research are gratefully acknowledged. 相似文献

Two experiments analyzed the effectiveness of goal statements in aiding recall of self-generated as opposed to experimenter-imposed command names. Subjects were presented with a series of before-after pairs representing the computer states before and after a command was executed. In Experiment 1, during study, one group of subjects generated a command name in response to each pair; a second group generated a goal statement describing the goal to be accomplished in addition to generating a command name. During recall, half of each group was required to recall the name, whereas the other half was required to describe the goal before attempting to recall the name. In Experiment 2, during study, command names (and goals for those subjects in the goal condition) were imposed by the experimenter rather than generated by the subject. Subjects who generated goals and names recalled more command names than did those who generated only names or who received imposed goals and/or names. Generation of an appropriate goal at study improved encoding by helping subjects to select more appropriate command names; generation of an appropriate goal at test improved retrieval for appropriate names only, presumably by activating a relevant subset of names. Even in the relatively simple task of naming and remembering command names, having an appropriate model of the domain through the use of specific goal statements substantially improved performance. 相似文献

This research tests Gilligan's hypothesis that men are more likely to consider moral dilemmas chiefly in terms of justice and individual rights, whereas women are more likely to be chiefly concerned with questions of care and relationships with others. In addition, we have investigated the effects of dilemma content upon orientation of moral judgment. Protocols from interviews with 50 college students, half women and half men, to three moral dilemmas were coded according to moral orientation. Results indicated that both moral orientations were widely used by both men and women, but that women were more likely to employ prodominantly care considerations. In a test of mean differences in proportion of justice responses, content of the specific moral dilemma showed a strong influence upon moral reasoning. Results suggest that both gender and situational factors need to be considered in our understanding of moral reasoning. 相似文献

Taking aim on empowerment research: On the distinction between individual and psychological conceptions 总被引:6,自引:0,他引:6

Empowerment theory need not remain a mystery. Efforts, such as those described in this special section, to outline more clearly the nomological network of empowerment at multiple levels of analysis will advance empowerment theory. Tough-minded rigorous research is needed to advance the concept of empowerment. Empowerment research requires us to shift our attention from a debate between the merits of research at one level of analysis versus another to building bridges between levels of analysis. We must integrate theories and methods from other disciplines and develop research strategies that incorporate qualitative procedures and the voices of the research participants. The papers in this special section take aim on these tasks and add to our understanding of empowerment. 相似文献

The purpose of this study was to assess the significance and structure of life domains of college students and to explore the patterns of gender differences on different indices of significance. Four hundred fifty-seven college students rated 21 life domains in terms of degree of importance, frequency of involvement, and level of impact. They also responded to a measure of global life satisfaction. Gender differences on significance indices were investigated by means of three types of analyses. First, gender mean ratings on 21 life domains were compared via one-way multivariate analyses of variance. Second, the underlying dimensions of the 21 domains for each gender were compared via exploratory factor analyses. Third, the correlation patterns between perceived positive impact of each life domain and life satisfaction were calculated separately for men and women. Within-group comparisons revealed that men and women shared the same nine most significant domains: education, friends, biological needs, leisure, family, health, couple, esthetics, and physical activities. However, several gender differences were consistently found in the three types of analyses. The results indicated that although traditionally feminine domains are rated as more significant to women than men, traditional masculine domains were rated as equally significant by men and women. Domains considered sex role neutral (e.g., personal planning) were rated as more significant by women than men. In general, women appear to experience greater cognitive, affective, and behavioral aspects of significance in a wider spectrum of activities and as well perceive their general life satisfaction as deriving from a broader range of sources. Results also highlight the importance of assessing the degree of significance of life domains as an initial step in the development of multidimensional self-related constructs.Preparation of this paper was made possible through grants from the Social Sciences and Humanities Research Council of Canada, the Fonds pour la Formation des Chercheurs et l'Aide à la Recherche (FCAR-Québec) and the Université du Québec à Montréal.

Peer and teacher assessments of aggression, social withdrawal, and likability using the Pupil Evaluation Inventory were recorded for 104 French Canadian girls and boys in grade 1. Self-reported delinquency and personality measures were administered to these children when they were in junior high school 7 years later. Linear regression analyses revealed significant predictive differences between the grade 1 assessment of girls and boys: For antisocial behavior, teacher and peer assessments of boys were equally good predictors, and the combination of the two assessments did not improve prediction; for girls, peer and teacher assessments taken separately were weak predictors, but, taken together, they were better predictors for girls than for boys; for personality, peers were better predictors than teachers both for girls and for boys. When categorical analyses were used to predict extreme antisocial behavior, peer and teacher assessments were equally good predictors for girls and boys. The use of peer and teacher ratings together, however, decreased the number of false positives. The implications of these findings for research and clinical work are discussed. 相似文献

Issues that arise in using game theory to model national security problems are discussed, including positing nation-states as players, assuming that their decision makers act rationally and possess complete information, and modeling certain conflicts as two-person games. A generic two-person game called the Conflict Game, which captures strategic features of such variable-sum games as Chicken and Prisoners' Dilemma, is then analyzed. Unlike these classical games, however, the Conflict Game is a two-stage game in which each player can threaten to retaliate — and carry out this threat in the second stage — if its opponent chose noncooperation in the first stage.Conditions for the existence of different pure-strategy Nash equilibria, or stable outcomes, are found, and these results are extended to situations in which the players can select mixed strategies (i.e., make probabilistic threats or choices). Although the Conflict Game sheds light on the rational foundations underlying arms races, nuclear deterrence, and other strategic situations, more detailed assumptions are required to tie this generic game to specific conflicts.Steven J.
