Traditional residential care environments for the elderly have been criticized because of the observed low levels of residents' engagement. Behavioural models of depression suggest an inverse relationship between engagement in pleasant activities and depression. The present study examined the relationship between depression and engagement in the residents of a home for the elderly. Correlational analyses indicated no relationship between level of depression and level of engagement but an association was found between level of depression and engagement in activities subjectively most enjoyed. There was considerable variation in the residents' perception of their behaviour; some residents viewed active engagement negatively whilst clearly enjoying behaviour that is technically disengaged. It is suggested that the results of the study emphasize the importance both of individual differences in behaviour and of covert behaviour. Implications for the engagement concept are discussed. In particular it is suggested that programmes in care environments aimed at increasing engagement in order to enhance the quality of life should focus more on the individual and on his perception of his behaviour.  相似文献

The concept “impossible figure” is analyzed by formalizing the interpretations of a polyhedral figure by an observer, and defining several types of inconsistency in such interpretations. Tests for these inconsistencies are developed using simple graph theory, and a sufficient condition is established for the feasibility of an interpretation. Finally, techniques are derived for the automatic construction of usual or unusual multibar figures.  相似文献

Male and female managerial, professional, and technical employees participated in a study to test for the existence of sex differences in (1) attitudes toward the risks and sacrifices associated with career advancement and (2) salary increments required to accept a promotion opportunity. Results showed no differences in male and female attitudes toward career advancement. In addition, men and women appeared to hold highly similar ideas about the size of salary increments necessary to induce acceptance of various hypothetical promotion opportunites. Findings are discussed in relation to common stereotypes regarding the career mobility of women.  相似文献

The aim of this study was to investigate the possible relations between specific personality variables and the effect of subliminal stimulation on choice behavior. It was hypothesized that subjects with low anxiety, less neuroticism, and external locus of control and the trait of extraversion would be more susceptible to subliminal stimulation. 38 undergraduate students were exposed to subliminal messages urging them to choose symbols instead of numbers or letters. Analysis showed that subliminal stimulation did not generate a preference for symbols over numbers or letters. No support was observed for the hypothesis of an association between susceptibility and personality variables. These results may be explained in terms of symbol choice being a neutral message that did not relate to the subjects' needs and motivation.  相似文献

This is a preliminary report of a project designed to increase hope and quality of life (QOL) in older persons through a series of five training sessions. The training sessions for the experimental groups are based on research on happiness, goal imagery, and time management. Data indicates that the training is effective in increasing expected QOL. Several measures of affect and stress are examined as a function of three time frames of self-reported QOL. Daily uplifts are significantly related to present and future QOL while measures of stress and major life changes are not. Correlations of affective measures with QOL tend to increase from time frames of the past five years through the present to the next five years, indicating the relevance of hope for older persons. Training for increased hope works with older persons. Data obtained in the process is used to address theoretical models of QOL in older persons. This project was supported by a grant from the American Association of Retired Persons Andrus Foundation.  相似文献

The midlife phase in the marital relationship is a complicated transition period, challenging the flexibility and coping skills of every couple. Separation-Divorce Initiation (S/DI) at this time can serve a special function in the change process required in this stage. A comprehensive therapeutic model for S/DI couples is described. It includes (1) assessment of the relationship's stamina and the function of the S/DI; (2) treating symptoms and reactions to the traumatic event in an emergency intervention mode; (3) steps and techniques to help the couple overcome the traumatic effects of the SD/I and to rebuild their relationship on a more appropriate basis.  相似文献

This research examined the extent to which the personality characteristics of agency and communion are sex linked, and the extent to which differences in these orientations can account for sex differences in reward distribution behavior. In two studies, the agency and communion level of large samples of male and female undergraduates were assessed. As expected, males were more agentic and females were more communal. Moreover, when subjects who scored high or low on agency and high or low on communion were asked to allocate rewards between themselves and a co-worker, these personality differences were related to their allocation decisions. These results were used as the basis for discussing the role that sex-linked personality differences might play in distributive justice judgments.This article is an adaptation of a colloquium presentation at the meeting of the American Psychological Association, Los Angeles, August 1981. The research reported here was supported by NIMH grant MH29987-1, Goals, Motives, and Norms of Reward Distribution, and by NIMH Biomedical Research Support Grant from the College of Social Science, Michigan State University.
