In this archival study the authors sought to determine the relationship, if any, between counseling outcomes and the topical focus in career counseling. Twenty-two counselors saw 46 adult clients at a community-based clinic for an average of eight sessions. Counseling outcome and topical focus (the extent to which the actual content of counseling sessions reflected relatively more vocationally or personally focused topics) were assessed from follow-up questionnaires to former career clients and from trained raters' evaluations of the counselors' written progress notes. Results showed that, from the counselors' perspective, outcomes were better when the focus of the sessions was relatively more vocational than personal and when relatively more interviews were held. Client satisfaction, on the other hand, was predictable only from the counselor's level of experience. Satisfaction with occupational status was not associated with any of the client, counselor, or treatment factors. Discussion focuses on the contribution of the results to career counseling practice and on the feasibility and validity of retrospective, archival research. 相似文献

We evaluated the effects of an 8-week progressive muscle-relaxation therapy regimen on the headache activity of 10 elderly tension-headache subjects. Posttreatment assessment at 3 months revealed significant decreases in overall headache activity (50% or greater) in 7 subjects. Significant clinical or statistical prepost differences, or both, were also found for the number of headache-free days, peak headache activity, and medication index. This is the first prospective study of tension headache in an elderly population, and, unlike previous retrospective studies, it suggests that relaxation therapy may be an effective intervention in the treatment of such headaches. 相似文献

The present study examined body image satisfaction, dieting tendencies, and sex role traits among a sample of black urban women. While women who felt “too fat” were more likely than other women to engage in both restrictive and nonrestrictive dieting tendencies, in general, the women's body weight and body image did not compel them to utilize extremely restrictive dieting practices. A sizable proportion of the sample reported body image dissatisfaction and weight concerns, yet this did not appear to exert an overwhelmingly negative influence over other aspects of their lives, such as participation in sports, exercise, and sexual activity. Body image satisfaction and sex role traits were related. Dieting tendencies were also related with body image satisfaction. These findings and implications for further research are discussed. 相似文献

In our rapidly changing environment, both profit and non-profit organizations confront an increasing demand for technological,
economic, and social innovation. In response to this demand, organizations are taking on the role of “change agents” by transforming
existing practices into innovative action. Libraries, as centers that accumulate and disperse knowledge, can support these
organizations in their “change agent” roles. This paper delineates the way public libraries can help organizations meet the
increasing need for external information associated with innovation. Policy issues concerned with efficient information transfer
to user organizationss are specified, and two concrete examples of information transfer systems are described. In order to
best utilize existing knowledge,personal-professional assistance in selecting potentially innovative,impersonal written materials is recommended.

This study examined the usefulness of an 8-week applied problem-solving training program. Specifically, the study examined (a) whether problem-solving training that emphasised self-management principles would be useful, (b) if the effects of training would persist over time, (c) whether an individual difference variable (problem-solving appraisal) would affect training outcomes, and (d) whether the cognitive responses of the subjects during the course of training were related to their problem-solving appraisal or the change process. Results indicated that problem solving training was effective at enhancing students’ problem-solving appraisal, and that the self-report changes were maintained at a 1 year follow-up. In particular, training seemed most useful for students who initially appraised their problem solving very negatively. Finally, the results suggested that the process-oriented cognitive responses were related to students' initial problem-solving self-appraisal as well as the impact of training. Implications of the results are discussed in terms of counselling interventions, problem solving training, the interpersonal influence process, and future research. 相似文献

This study investigated social sensitivity and self-concept in students with learning disabilities (LD) and their non-learning-disabled (non-LD) peers. Thirty students each from public junior and senior high schools and a community college participated in the study; at each grade level, half were identified as learning disabled and half experienced no learning problem. Students were individually assessed in 30-minute interviews for their accuracy in interpreting the thoughts and feelings of actors in tape-recorded stories depicting two adults in happy angry, anxious, and sad interactions. A questionnaire assessing four dimensions of self-concept in learning situations (motivation, task orientation, problem-solving ability, and class membership) was also administered. LD students at all grade levels were significantly less accurate at interpreting social situations than were their non-LD peers, and had significantly lower self-concepts. These results support the need for remediation efforts specifically aimed at social skills for overcoming social deficits in adulthood. 相似文献

Differences in school behavior and achievement between students from intact, reconstituted, and single-parent families were analyzed. Students from intact two-parent families had fewer absences and tardies, higher grade point averages, and fewer negative and more positive teacher behavioral ratings than did those from reconstituted and single-parent families. 相似文献

To investigate the moderating role of individual differences in hypnotic susceptibility and visuospatial skills on afterimage persistence, we presented a codable (cross) flash of light to 40 men and 46 women who had been dark adapted for 20 min. In an unrelated classroom setting, subjects had previously been given two standardized scales of hypnotic susceptibility (Harvard Group Scale of Hypnotic Susceptibility, Shor & Orne, 1962; Group Stanford Hypnotic Susceptibility Scale, Form C, Crawford & Allen, 1982) and the Mental Rotations Test (Vandenberg & Kuse, 1978). The first afterimage interval and the afterimage duration correlated significantly with hypnotic responsiveness, supporting Wallace (1979), but did not show the anticipated relationships with mental rotation visuospatial skills. Individuals in the high hypnotizable group had (a) significantly longer afterimage intervals between its first appearance and first disappearance than did those in medium or low groups, as well as (b) significantly longer afterimages between the first appearance and the final disappearance than did those in low groups, but those in medium groups did not differ significantly from the other groups. Discriminant analysis using the afterimage persistence measures classified correctly 65.2% of high hypnotizables, 37.5% of medium hypnotizables, and 54.8% of low hypnotizables. Hypothesized cognitive skills that assist in the maintenance of afterimages and underlie hypnotic susceptibility include abilities to maintain focused attention and resist distractions over time and to maintain vivid visual images. 相似文献

The role of lateral masking in more rapid performance improvement with peripheral than with central precuing was investigated. A peripheral precue to the inside of the target location provided less masking at zero precue-target delay than a precue to the outside (experiment 1) or a precue involving a partial target at the target location (experiment 2). There was no significant interaction between precue-target delay and precue type in a comparison of inside precues and precues involving a briefly-brightened box around the target location, although overall performance was significantly poorer with the latter (experiment 3). Performance was better at short precue-target delays with inside precues than with central precues (experiment 4), yet it did not improve significantly more rapidly. Minimizing lateral masking with peripheral precues thus eliminates the dramatic performance improvement sometimes observed across short precue-target delays, causing performance to be consistently better than with central precues across these delays. 相似文献

Our goal was to test whether current hemisphere predominance is a predictor of scores on standardized measures of personal optimism and preference for risk. In two between-subject experiments, current hemisphere predominance was measured by the direction and extent of line bisecting errors. Pearson correlations and median splits of the line bisecting errors showed significantly greater personal optimism and preference for risk with left hemisphere predominance. These results support previous research in which manipulation of hemisphere predominance produced similar effects on personal optimism in normal individuals and on risk taking in lesioned and normal samples. We conclude that the association of optimism and risk with left hemisphere predominance can be observed in resting as well as in manipulated situations. 相似文献
