This study investigated whether consultees' understanding and use of problem definition skills could be enhanced by increasing their awareness of these processes during consultation interactions. Subjects assigned to a consultation with cognitive modeling group viewed videotaped consultation interactions in which consultants' verbalizations during the problem definition stage of consultation frequently included overt references to the problem-solving processes being used by these consultants. Subjects in a consultation without cognitive modeling group viewed similar interactions except that the consultants' statements did not include overt references to problem-solving processes. A control group viewed irrelevant interactions between consultants and consultees. Data analyses indicated that the subjects exposed to consultations that included cognitive modeling components wrote better problem definitions and were better able to describe the process for defining children's problems than subjects in either the consultation without cognitive modeling or control groups. The subjects in the consultation without cognitive modeling group generally did better than those in the control group.  相似文献

Subjects (N=439) were asked to write an account of an achievement of failure, and to describe it in terms of locus of standards (internal-external), conceptual focus (process-impact), and initial expectations for success (or failure). Additionally, accounts were classified on the basis of achievement domain (personal, interpersonal, mastery). Analyses of variance [2 (sex)×3 (domain)] for each cognitive measure revealed few sex differences. However, cognitive responses did vary as a function of achievement domain. Main effects for domain were observed under success instructions for locus of control (p<.0002) and under failure instructions for locus of control (p<.05), conceptual focus (p<.05), and expectations (p<.06). Interaction effects of sex and achievement domain were observed on locus of standards for success (p<.0002) and initial expectations preceding failure (p<.025), indicating that women were more responsive to domain differences than were men. Discriminant analyses indicated that cognitions were more readily patterned in terms of achievement domain than sex. Elaboration and incorporation of the concept of domain in cognitive models of achievement is suggested.  相似文献

Six studies of children's comprehension of the passive transformation and of the Minimum Distance Principle are reviewed and their results integrated. Children were in kindergarten through Grade 6, inclusive. Expectations about usual grammatical relations (e.g., agent/action combinations) significantly affected children's comprehension: sentences reflecting expectations were understood more often than sentences contradicting children's expressed expectations. Results are discussed within the framework of referential event strategies in understanding spoken language. Limits of the effect of children's expectation on comprehension are described, including general cognitive developmental status, relevant belief systems, and nature of the psycholinguistic task.  相似文献

A series of predictions concerning adult sex-role ideology was derived from three theoretical approaches commonly applied to the sex-role development of children: secondary reinforcement, operant conditioning by peers, and status envy. Relevant data were collected by means of a questionnaire administered to 635 students at two regional state universities and to nonstudent adults in the surrounding communities. Of these, 226 were classified as having a distinctive contemporary or traditional sex-role ideology by means of a short test developed and validated by the authors for this purpose. Discriminant analyses indicated that each theoretical approach differentiated between contemporary and traditional subjects at levels significantly better than chance. However, the status envy approach, as modified by social learning theory, was most effective and correctly classified 85% of the females and 93% of the males according to their sex-role ideologies. Alternative explanations of results are discussed and an eclectic model is advocated.The authors would like to express their sincere appreciation to Dr. Barbara Wallston for her comments on an earlier draft of this paper, and to Jan Curley for computer assistance.  相似文献

Performance in Cooper and Shepard’s (1973) mental rotation task was examined in the context of a model that defined the extent to which alphabet letters could be tilted from their normal orientation and still be perceptually upright. For letters with a broad range of orientations for which they remain perceptually upright, a nonlinear effect of orientation on reaction time was obtained (as in Cooper and Shepard). However, for letters with a narrow range of orientations for which they remain perceptually upright, reaction time was linearly related to orientation. The results supported the hypothesis that subjects in the Cooper and Shepard task would mentally rotate alphabet letters only when they were presented in orientations for which they were not perceptually upright.  相似文献

The present study was designed to assess whether applicants for a sex-incongruent position would be evaluated less favorably by personnel administrators than applicants for a sex-congruent position. It was predicted that negative evaluations of sex-incongruent applicants would increase as a function of participants' reliance on sex-role stereotypes. Forty-four personnel administrators were asked to review the qualifications and evaluate one of four job applicants. Sex of the applicant and sex-orientation of the position were systematically varied. Participants were presented with credentials of a male or female applicant for a traditionally male- or female-oriented position. While results did not support Cohen and Bunker's contention that sex-incongruent job applicants would be viewed less favorably, the data did suggest that evaluations of the sex-incongruent applicants (especially the female applicant) varied as a function of sex-role stereotyping.The authors wish to gratefully acknowledge the assistance provided by Thom Hurlburt, Joan Van Tassel, and Amy Post.  相似文献

In a replication of a study by Taylor and Falcone (Cognitive Bases of Stereotyping: The Relationship Between Categorization and Prejudice, Personality and Social Psychology bulletin, 1982, 8, 426–432), subjects (n=161) listened to videotapes of three males and three females in a staged discussion of ways to increase voter turnout. Subjects subsequently attempted to identify which speaker had made each of the suggestions offered during the discussion. In confirmation of Taylor and Falcone, both sexes made significantly more within-sex than cross-sex attribution errors, suggesting the importance of gender in processing information. Subjects also rated the speakers on items reflecting their likability and their competence. Contrary to Taylor and Falcone, no promale prejudice effects were found. Relationships were also determined between the dependent variables and subjects' scores on a measure of sex role attitudes and on the M (instrumentality) and F (expressiveness) scales of the Bem Sex Role Inventory (BSRI; S. L. Bem, The Measurement of Psychological Androgyny, Journal of Consulting and Clinical Psychology, 1974, 42, 155–162) and the Personal Attributes Questionnaire (PAQ; J. T. Spence, R. Helmreich, and J. Stapp, The Personal Attributes Questionnaire: A Measurement of Sex-Role Stereotypes and Masculinity-Femininity, JAS Catalog of Selected Documents in Psychology, 1974, 4, 143). No Significant BSRI or PAQ effects emerged, thus failing to replicate either the results for within-sex errors reported by Taylor and Falcone or those subsequently reported by Frable and Bem (If You Are Gender Schematic, All Members of the Opposite Sex Look Alike, Journal of Personality and Social Psychology, 1985, 49, 459–468).The authors wish to thank Glenn Cunningham, who served as experimenter along with the first author.  相似文献

Developing community capacity to improve health is a cornerstone of community-based public health. The concept of community capacity reflects numerous facets and dimensions of community life and can have different meanings in different contexts. This paper explores how members of one community identify and interpret key aspects of their community’s capacity to limit the availability and use of tobacco products. Particular attention is given to examining the interrelationship between various dimensions of community capacity in order to better understand the processes by which communities are able to mobilize for social change. The study is based on qualitative analysis of 19 in-depth interviews with key informants representing a variety of community sectors in Harlem, New York City. Findings indicate that the community is viewed as rich in human and social resources. A strong sense of community identity and connectedness underlies this reserve and serves as a catalyst for action. At the time this study was conducted, all authors were at Columbia University Mailman School of Public Health.  相似文献

Progesterone (P(4)) and its metabolite, 5alpha-pregnan-3alpha-ol-20-one (3alpha,5alpha-THP) have trophic effects and may improve cognitive function. We investigated the role of progestins in a murine model of Alzheimer's Disease (AD) in which transgenic mice co-overexpress a mutant form of amyloid precursor protein (APPswe) and a deletion in presenilin 1 Delta exon 9 (APPswe+PSEN1Deltae9). We hypothesized that: (1) mice with the APPswe+PSEN1Deltae9 mutation would have performance deficits compared to wildtype mice and (2) long-term administration of P(4) would enhance cognitive performance and increase brain progestin levels over placebo. Mice were ovariectomized at 6 months of age and administered placebo or P(4) via subcutaneously implanted pellets. Mice were tested between 9 and 12 months of age for cognitive performance in the object placement, water maze, object recognition, and T-maze tasks and for motor behavior in an activity monitor and then tissues were collected for steroid measurement. P(4) administration increased progestin levels in cortex, diencephalon, midbrain, and cerebellum of wildtype and mutant mice, but increases in 3alpha,5alpha-THP levels in the hippocampus of APPswe+PSEN1Deltae9 mutant mice were attenuated compared to that observed in wildtype mice. APPswe+PSEN1Deltae9 mice showed poorer performance in hippocampus measures (object placement and water maze tasks). In the object recognition and T-maze task, which are mediated by the cortex and hippocampus, P(4) administration improved performance in both wildtype and APPswe+PSEN1Deltae9 mutant mice compared to placebo administration. Thus, APPswe+PSEN1Delta9 mice have deficits in hippocampal performance and capacity to form 3alpha,5alpha-THP in the hippocampus and both wildtype and APPswe+PSEN1Delta9 mice show beneficial effects of P(4) in cortical function and similar capacity to form 3alpha,5alpha-THP in the cortex.  相似文献

This study was aimed at clarifying conceptualisations of hope amongst vulnerable young people in a high HIV/AIDS prevalence South African setting. Participants were four young people ranging from 15 to 19, and interview data were collected on their household conditions, lived experiences in the communities and schools, and family support systems. Analysis applied grounded theory process to characterise main themes. Four mechanisms characterised the nurturing of hope processes in the context of vulnerability, namely: predatory, protective, promotion and possibility processes. Six protective intrapersonal themes were also identified: finding purpose, building a sense of the future; building faith in a higher power; embracing educational opportunities; thinking positively; building on strengths; and adopting supportive networks. Findings suggest that conceptualisations of hope need to be grounded in social context and the imperatives of social justice to support vulnerable young people in realising their future aspirations.  相似文献
