Research on the environmental psychology of later life has produced data and theoretical advances that have been incorporated into the design of nursing homes and housing, neighborhood planning, housing policy, and housing-related services for older people. The applications of knowledge have been particularly useful in compensating for behaviors impaired by the physical illnesses that become more prevalent with aging. Some research has also documented environmental transactions made with the intent of choosing, creating, or shaping environments that increase need fulfillment. These two directions of the transactions between the older person and the environment have been characterized as environmental docility and environmental proactivity. The need for more research on promoting opportunities for proactivity in an attempt to raise environmental quality is discussed.  相似文献

The present study was designed to determine the main effects of alcohol intoxication on self-report and physiological measures of anxiety. Second, we aimed to assess the role of the Marlowe-Crowne Social Desirability (MCSD) scale in predicting the relationship between self-report and physiological indices of anxiety irrespective of drink content. A final purpose of the study was to determine whether the MCSD could account for discrepancies in the effects of alcohol on the two anxiety response systems. Subjects were male social drinkers who received an 0.70 g/kg dose of alcohol or placebo. Results indicated that irrespective of drink content, subjects with high MCSD scores reported lower levels of anxiety than did subjects with low MCSD scores. This relationship was not evident for heart rate. These results for measures of anxiety were not influenced by drink content.  相似文献

The authors view unconscious fantasy from the perspective of self psychology as a significant addition and emendation of the classical framework. A selective review of the pertinent literature is presented, followed by clinical material illustrating the contribution of self-psychological concepts to the understanding of unconscious fantasy formation.  相似文献

Increasingly, psychological assessment is conducted with clients and patients involved in child custody and personal injury litigation. Clinical neuropsychologists are being asked sophisticated questions by attorneys regarding the validity of practitioners' most highly respected tests. Research reviewed here bears on the validity of test-buttressed clinical opinions, including research related to the following psychometric properties of individual test scores: standard errors of measurement, test-retest stability and subtest-to-subtest intercorrelations. The highest and the lowest subtest scores used as indices, respectively, of an individual's premorbid level of cognitive functioning and the degree of current impairment from that presumed earlier level is not justified when used in isolation from the life history and current medical findings. Although many practitioners use information from the wider research, courtroom experience suggests that a number do not; contrariwise, the attempt of Faust and Ziskin (1988a) to undermine the courtroom testimony of every psychologist who serves as an expert witness is also criticized.  相似文献

Escape and avoidance that are disproportional to the danger of the pertinent stimulus are important clinical problems that are often related to inaccurate (catastrophic) expectations. One possible source of such expectations is a prior, underestimated aversive experience. In the present experiment the hypotheses that underestimated pain leads to escape and that it leads to avoidance were tested. In order to control for the effect of the intensity of the pain stimulus, a control group that received 20 pain stimuli of high intensity was formed. Subjects in the experimental condition received 17 pain stimuli of low intensity and 3 of (unexpectedly) high intensity (experimentally induced underprediction). Underprediction of the high intensity stimulus was significantly related to escape, but not to avoidance. The results suggest that the way in which avoidance was operationalized accounts for this. The strong support of the hypothesized relationship between underpredicted pain and escape is an important finding, however.  相似文献

A survey of the role of gender in family therapy training programs was conducted by the Women's Task Force of the American Family Therapy Association (AFTA) in order to determine the extent to which gender issues were included in the curriculum. Questionnaires were sent to 285 programs in the U.S., Canada, and overseas. Only 19% (n = 55) of the original sample participated, with the East Coast representing the largest proportion of respondents. Findings revealed that the three most frequently addressed gender issues are: 1) the impact of cultural and economic conditions on single, female-headed families; 2) gender issues associated with wife abuse; and 3) an examination of the implications of the therapist's gender in therapy interventions. Only 27 programs identify with a feminist model or have a clearly defined sense of gender awareness. A significant finding associated with the introduction of feminist content was the difficulty of integrating gender issues with major theoretical models. Trainee resistance and lack of faculty awareness were also considered obstacles to including gender in program curriculum.  相似文献

Research on earlier versions of the Family Adaptability and Cohesion Evaluation Scales (FACES) has ostensibly shown that the scales lack discriminant and convergent validity (23). However, these studies have defined convergence as agreement between family members or as agreement between family members and family therapists. Such definitions confound real differences between respondents' perceptions of the family with the notion of convergent validity. In the current study, we take a different approach to construct validity. Multiple measures of family adaptability, cohesion, and talkativeness were administered to two family members (insiders) and two significant others (outsiders). The two insiders' responses were averaged together, as were the two outsiders' responses. Using confirmatory factor analysis, we demonstrated that family adaptability, cohesion, and talkativeness are distinct traits, and that the different sources of information about these traits, including FACES-III (24), have convergent validity.  相似文献

It has been argued that young preschoolers cannot correctly attribute a false belief to a deceived actor (Wimmer & Perner, 1983). Some researchers claim that the problem lies in the child's inadequate epistemology (Chandler & Boyes, 1982; Wellman, 1988); as such, it is specific to the child's theory of mind and no such problem should appear in reasoning about nonmental representations. This prediction is tested below in the "false photograph" task: here an actor takes a photograph of an object in location X; the object is then moved to location Y. Preschool subjects are asked: "In the picture, where is the object?" Results indicate that photographs are no easier to reason about than are beliefs. Manipulations to boost performance on the photograph task proved ineffective. Further, an explanation of the failure as a processing limitation having nothing to do with the representational nature of beliefs or photographs was ruled out. It is argued that young children's failure on the false belief task is not due to an inadequate epistemology (though they may have one) and is symptomatic of a larger problem with representations.  相似文献
