Previous research has demonstrated the relationship of work stress to indices of job strain, as well as underscoring the importance of moderating variables. In the present study of a mining organization it was hypothesized that personnel associated with actual mining operations would demonstrate stress-strain relationships different from those associated with administrative and staff work. Measures of stress and strain were obtained from management staff of blue-collar and white-collar groups to assess the moderating influence of collar color. Results strongly support collar color as a moderator variable. In particular, the two groups differ significantly with respect to how role conflict, job security, quantitative work load, variation in work load, and utilization of skills impact various strains. The effect of job function on stress and strain and possible practical implications of these results are discussed. 相似文献

In two experiments, posthypnotic amnesia was suggested for a word list memorized during hypnosis. After an initial test of amnesia the subjects gave word associations (Experiment 1) or category instances (Experiment 2) to stimuli intended to elicit the critical (word list) items covered by the amnesia. The extent of initial amnesia observed was strongly associated with measured hypnotic susceptibility. Even among the most hypnotizable subjects, however, the dense amnesia did not prevent the critical items from being elicited by the semantic memory tasks, nor did it modulate the priming which these associations received by virtue of the prior learning experience. Moreover, production of the critical items did not, in general, remind the amnesic subjects of those items which they had previously learned, but could not now remember. Full memory was restored after the amnesia suggestion was canceled by a prearranged cue. Posthypnotic amnesia appears to represent a temporary dissociation of episodic features from memory traces, so that the subject has difficulty in reconstructing the context in which the target events occurred. 相似文献

The critique of learned helplessness research and theory and the alternative schedule-shift discrimination hypothesis offered by McReynolds (Journal of Research and Personality, 1980,14, 139–157) are considered. Each point made by McReynolds is discussed and a variety of recent experimental evidence is reviewed. It is concluded that McReynolds' critique is without substance and that the schedule-shift discrimination explanation of the learned helplessness effect is contradicted by existing data. 相似文献

A teacher scale based on DSM-III-R diagnostic criteria for attention deficit hyperactivity disorder (ADHD) was developed for the behavioral assessment of children in Brazil. A total of 2, 082 children (782 males and 1,300 females) with a mean age of 11.2 years who were attending a public school in the greater Rio de Janeiro area were the subjects of this study. Two factors (Hyperactivity-Impulsivity and Inattention) were extracted from a principal-factor analysis conducted on the data, and the factor structure of the scale was found to be stable. Ratings of boys were higher than ratings of girls, and younger children had higher ratings than older children for both factors. Test-retest reliability for each item of the scale ranged from .56 to .70. The data are discussed in view of current controversies in the factor structure of teacher ratings of DSM-III-R ADHD symptoms.This research was supported by FINEP (42.88.0138.00) and FUNPENE.

Both theoretical arguments and laboratory evidence indicate that society awards earned dignity (worth) to persons perceived as voluntarily performing praiseworthy behaviors. Laboratory research, as well as common observation, indicates also that society accords an intrinsic dignity unconditionally to all people. On a questionnaire given in class, college students reported increased dignity earned by the Russians from their praiseworthy (i.e., embracing freedom) and voluntary rejection of the attempted coup in 1991. The questionnaire also revealed a general belief in intrinsic dignity. External evidence for earned dignity is shown by increased international support for the Russians after rejection of the coup. This convergence of laboratory and external data validates the laboratory techniques for studying social perception of human dignity. 相似文献

Abstract— Does group discussion and deliberation on one issue or task influence the members' decisions or opinions on other issues? In contrast to past research looking solely at changes in responses to the same item discussed by the group, this study examined whether group interaction results in members changing the way they make judgments on related items in the future. The results show that group discussion and consensus on one set of judgments led to a significant convergence of judgmental strategies that extended to a related (but different) set of judgments the members made later as individuals. 相似文献

Traditional and nontraditional women and men's perceptions of ideal people, in terms of both traits and physiques, were assessed using 80 male and 80 female Caucasian undergraduates as study participants. The data indicated that traditional women and men perceived the ideal male as mesomorphic and as having more instrumental than expressive traits. Nontraditional women and men also favored a mesomorphic physique for the ideal male, but they differed from traditionals in that they saw this mesomorphic male as being androgynous in regard to traits. Concerning the ideal female, traditional and nontraditional women and men preferred an androgynous physique, but they differed in their perceptions of the ideal personality for a woman. Traditional women and men perceived their ideal women as having more expressive than instrumental traits, whereas nontraditional women and men saw their ideal women as being androgynous in regard to traits. The results are discussed within the framework of Bem's gender schema and enculturated lens theories. 相似文献

Gibson (1966, 1979) suggested that an important property of perception is that the observer is active. Two experiments were conducted to examine the benefits of active observation in determining dynamic spatial orientation. Subjects were presented with displays simulating locomotion through a three-dimensional environment. Active observers continuously controlled locomotion, whereas passive observers viewed the display. During the trial, the display was blacked out for a brief period, followed by a static image that was at either the correct or the incorrect orientation following the blackout. Subjects were required to indicate whether they were positioned at the correct extrapolated orientation. The presence or absence of orientation change, the type of change (changes in rotation about the depth axis [roll], horizontal axis [pitch], or forward translation), the duration of the blackout, and the consistency of change were varied. In addition, the experiments used either a compensatory or a pursuit tracking task. Active observers had greater sensitivity than did passive observers in detecting a change for both tracking tasks. Subjects in both experiments exhibited greater sensitivity in detecting inconsistent changes (relative to consistent changes), suggesting that the dynamics specified by optical flow were incorporated in extrapolated orientation. In addition, sensitivity decreased with an increase in blackout duration. The results are discussed in terms of an extrapolation model of perception that incorporates the responses executed by active observers. 相似文献
