成人日常问题解决的老化研究

日常问题解决能力是近十几年来老年心理学中研究比较活跃的一个领域。本文介绍了有关日常问题解决研究的四种理论,即心理测量的智力内隐理论、形式后思维的辨证思维理论、信息加工理论和社会认知与智慧理论,及其初步的研究成果,并进一步指出在理论上整合和在实践中开展干预的研究方向。     

male self-control and sexual aggression

This study examines judgments of male self-control regarding sexual aggression in dating situations. A survey was conducted using vignettes that described situations where a hypothetical man attempts to have intercourse with his female date, she resists, and he considers various ways of overcoming her resistance. Survey respondents judged these vignettes. The goals of the study were to estimate the prevalence of beliefs about low male self-control, and to examine how contextual information affects these assessments. Contrary to expectations derived from the literature, the large majority of respondents attributed high levels of self-control to men across a wide range of scenarios. As expected, the man's alcohol intoxication reduced perceived control. Against expectations, consensual foreplay and prior sex did not affect ratings. Implications for social learning and rational choice theories of sexual aggression are discussed, with particular emphasis on Ajzen's (1988) theory of planned behavior.     

Longitudinal changes in college math students’ implicit theories of intelligence

This study examined changes over time in implicit theories of intelligence and their relationships to help-seeking and academic performance. College algebra students completed questionnaires during the second week of classes and 2 weeks before the end of the semester (ns = 159 and 145, respectively; 61 students completed questionnaires at both waves). The questionnaires assessed entity and incremental implicit theories of general and math intelligence (beginning and end of semester) and help-seeking (end of semester). Results indicated that students had more incremental views of general than math intelligence. Further, their views became less incremental over the course of the semester; however, this decrease was greater for math than for general intelligence. Participants who exhibited a stronger incremental theory of general intelligence at the beginning of the semester subsequently reported greater help-seeking during the semester. Finally, students who had more entitative views of math intelligence earned lower course grades.     

Chronic stress, metabolism, and metabolic syndrome

The prevalence of obesity has rapidly escalated and now represents a major public health concern. Although genetic associations with obesity and related metabolic disorders such as diabetes and cardiovascular disease have been identified, together they account for a small proportion of the incidence of disease. Environmental influences such as chronic stress, behavioral and metabolic disturbances, dietary deficiency, and infection have now emerged as contributors to the development of metabolic disease. Although epidemiological data suggest strong associations between chronic stress exposure and metabolic disease, the etiological mechanisms responsible remain unclear. Mechanistic studies of the influence of chronic social stress are now being conducted in both rodent and nonhuman primate models, and phenotypic results are consistent with those in humans. The advantage of these models is that potential neural mechanisms may be examined and interventions to treat or prevent disease may be developed and tested. Further, circadian disruption and metabolic conditions such as diabetes mellitus could increase susceptibility to other stressors or serve as a stressor itself. Here, we review data from leading investigators discussing the interrelationship between chronic stress and development of metabolic disorders.
