The Threat Index and the Death Anxiety Scale were administered to 228 subjects. Based on the high/low criterion scores, 105 subjects were assigned to the following four groups: (a) high death threat/high death anxiety, (b) high death threat/low death anxiety, (c) low death threat/high death anxiety, and (d) low death threat/low death anxiety. During the experimental phase of the study, subjects viewed a filmstrip on death rituals in various cultures. A recall test was then administered. Results indicated no significant group differences on recall performance. Initial no-show rates for the second part of the experiment were observed in the four groups reflecting a significant negative relationship between death anxiety and initial no-show rates. The possibility of defensive responding on the Death Anxiety Scale was suggested.  相似文献

The self-consciousness scale of Fenigstein, Scheier, and Buss (1975) was subjected to internal and external consistency tests based on the classical test theory model. The scale was found to have five underlying dimensions: two for private self-consciousness (viz., self-reflectiveness and internal state awareness), two for public self-consciousness, and one for social anxiety. The confirmatory factor analysis procedures employed by Burnkrant and Page (1984) are shown to be fallible as indicators of unidimensionality. Theoretical implications of newly identified dimensions in the public self-consciousness subscale are discussed.  相似文献

Invariance in the MMPI's component structure   总被引:1,自引:0,他引:1  
Bernstein and Garbin (1985b) suggested that the Minnesota Multiphasic Personality Inventory's major clinical scales (excluding Scales ? and 5) can be approximated by an oblique three-component structure: (a) Profile Elevation, (b) Test-taking Attitudes, and (c) Optimism-Pessimism, collectively termed the salient weight model. In this study, we found that both this model and the MMPI's principal component structure remain invariant across race, sex, and, as previously noted, context of testing (job applicants vs. inmates in correctional institutions). We further noted that several alternative definitions of Profile Elevation provide equally satisfactory representation of the relations among the scales. This factor invariance is necessary, but not sufficient, for the MMPI to be viewed as unbiased.  相似文献

Male liberation     
This article on Liberation approaches the subject from the perspective ofmen. Women have taken the lead in trying to throw off the bondage of patriarchy. Men have, for the most part, been reactors to the evolving changes. The author feels that there is a more creative role for men to play, but first, we must become more conscious of the ways in which our privileged position oppresses us. The author documents this dynamic as well as points to some possible directions for men to move in their personal and professional lives. The priority on developing collegiality and inclusiveness in our professional associations gives this subject an important place in our thinking and decisionmaking.This paper was read at a workshop on male liberation at the National A.A.P.C. Convention in San Antonio, April 30,1982.  相似文献

Pigeons' responses were reinforced on a variant of a mixed variable-interval extinction schedule of reinforcement in which the transition to the higher reinforcement rate was signaled by a trace stimulus projected on the response key prior to the onset of the component correlated with food delivery. In the first of two experiments, the duration of the trace stimulus preceding the component correlated with food delivery was varied from 1.5 to 50.0 s and in the second experiment, the reinforcement frequency in the same component was varied from 10 to 60 reinforcers per hour. Pigeons pecked at the trace stimulus preceding the onset of the component correlated with food delivery even though responding was not reinforced in its presence and only one of the changes in reinforcement rate (i.e., from extinction to reinforcement) was signaled. The rate of pecking during the trace stimulus was a function of its duration but not of the reinforcement frequency in the following component. Higher rates generally occurred at the shorter trace-stimulus durations. Component responding following the offset of the trace stimulus was under discriminative control of the trace stimulus whether or not responding occurred in the presence of the trace stimulus.  相似文献
