Previously we (Bruno & Cutting, 1988) explored the perception of spatial relations among objects laid out in a computer-generated environment. In his commentary on our article, Massaro (1988) raised several issues. The most important is from his reanalysis, which indicated that--because of a subadditive trend in the results--additive and multiplicative strategies fit our data in Experiment 1 about equally well. In reply, we performed a different analysis. Results corroborate subadditivity--and hence multiplicative information combination--in Experiment 1 but provide no evidence for it in Experiments 2 and 3. On the whole, then, the results still support additivity more strongly than any other combination rule and thus support our notion of minimodularity. 相似文献

A questionnaire measuring respondents' beliefs about the attitudes regarding female achievement held by their parents was distributed to 326 women attending a state university. Women who report frequent bingeing are more likely than other women to report that (1) their parents believed a woman's place is in the home (2) their mothers were unhappy with their own careers, (3) their fathers thought the respondents' mothers were not intelligent, and (4) their fathers treated a male as the most intelligent sibling in the family. Reports of fathers' attitudes regarding mothers' intelligence and the proper role for women are related to respondents' self-reports of purging, but only among those women who are much more concerned with academic achievement than with household skills. 相似文献

The sensitivity of naturalistic prose material to retroactive interference (RI) was investigated in three experiments, with due consideration given to the conditions known to produce RI in non-prose material. In experiment 1, unrelated, related, and nearly identical (parapharase) prose passage conditions yielded a pattern of results very similar to those obtained with non-prose material, with only the related condition associated with significant amounts of RI. Based upon these results and a few simple assumptions, a classificatory scheme was developed within which predictions were made regarding RI in related prose material. Several such predictions were tested and confirmed in Experiments 2 and 3. It was concluded that the many previous failures to detect RI in the retention of prose may be attributed to factors other than any inherent insensitivity of the material itself, and that RI may be just as predictable in prose as it is non-prose material. 相似文献

Previous research on the effect of lecture handouts on student learning indicates that students who are given skeletal handouts usually perform better in course examinations than students who take all their own notes. The present study investigates whether the amount of detail in the handout is a critical factor in this. A randomized groups experiment was conducted in the context of a course on dental surgery. Four lecture handout conditions (headings and full text; headings and key points; headings only; no supplementary materials) were compared on tests 2 days and 2 weeks after the lecture. The significant differences between conditions were: ‘headings only’ better than ‘headings and key points’ on the first test; ‘headings only’ better than ‘no supplementary materials’ on the second test; and ‘headings and full text’ better than ‘no supplementary materials’ on the second test. These results indicate that the amount of detail is a critical factor in handout effectiveness. 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

A recent clinical study of outpatient psychotherapy groups in a community mental health center explored the linkage between group leadership variables, group climate, and outcome. The study involved nine outpatient therapy groups, over 50 group clients, and several group therapists. A repeated measures design involving assessment of clients' outcome and level of functioning, group leadership style, and group climate was used to assess changes over a 6-month period. The findings suggest: 1) a reduction in symptoms and improved functioning for clients; 2) a similarity of perceptions by members and leaders of perceived leadership behaviors and group climate; 3) the presence of direct and indirect influences of group climate and leadership behavior on clients' outcome; and 4) a linkage between leadership behavior and group climate with the theoretical orientation of the group. The findings of the research are discussed in relation to the understanding of specific effects in group psychotherapy and the implications for construction of group psychotherapy theory.The authors would like to thank Robert Dies, Ph.D., for his helpful suggestions in the early phase of this study; Roy MacKenzie, M.D., for permission to use the Group Climate Questionnaire; Diane DePalma, Ph.D., for permission to use the Global Leadership Behavior Index; Chris Boltwood, B.A., for her untiring efforts in administering the instruments and coding and entering the data; and most importantly, the psychotherapy group members and the group therapists for their cooperation in this endeavor—without their help, this clinical study would not have been possible.A version of this paper was presented at the Annual Meeting of the American Group Psychotherapy Association, 1987, New Orleans, Louisiana. Lenore Phipps, R.N., M.S., C.S., was formerly Director, Group Psychotherapy Program at Park Ridge Mental Health Center, Rochester, now in private practice at Guild Medical Center, Norwood, MA 02062. 相似文献

An emergent social science of knowledge applications, drawing on a substantial multidisciplinary literature published over the past twenty-five years, signals an inversion of typical scholarly reasoning about the knowledge-society nexus. Whereas most scholarly research thus far has concentrated on conditions believed to affect the production of scientific and professional knowledge, we pose a new problematic: What must we examine in order to comprehend and consciously shape applications of scientific and professional knowledge to the manifold problems facing contemporary societies? To date, approaches to this problematic have proceeded on the basis of four broadly accepted if abstract theses about the nature of contemporary knowledge systems: subjectivity, corrigibility, sociality, and complexity. Within the boundaries supplied by these commonly accepted theses are unresolved controversies expressed in competing visions of complexity, alternative perspectives of causation, rival images of progress, and conflicting criteria of application. 相似文献
