In this study of the way 32 men and women between the ages of 60 to 90 coped with stressful situations, two instruments were used: the Life Experiences Survey and the Ways of Coping Checklist. Overall, health-related concerns were more frequently reported by older adults than any other stressful event. When coping responses were categorized according to four modes--intrapsychic, inaction, direct action, and information seeking--the Appalachian group was found to use the information-seeking mode; the Cherokee group, the intrapsychic mode. Significant differences were found between males and females in coping modes and life-stress categories. When groups were combined, significant correlations were noted between life stress, particularly health-related stress, and the coping modes of intrapsychic and information seeking. 相似文献

Age and sex differences in the cooperative and noncooperative behavior of pairs of American children
Game playing behavior of same and mixed sex pairs of 5-, 8-, and 11-year-old American children was compared, using a game in which cooperative behavior maximized reward. Pairs of 8- and 11-year-old children were relatively more cooperative and attained significantly more Joint Reward Goals than 5-year-old pairs. Older pairs were not maximally cooperative, however, in terms of all the dependent measures; in adjusting for initial differences on practice trials, 5-year-olds and 8-year-olds took less time than the 11-year-olds, and 11-year-old pairs of boys took significantly more time than all other pairs. In addition, cooperative behavior increased across trials, especially for the 11-year-old children. 相似文献

Thirty-eight chronically mentally disabled patients who were invited to join a newly established, vocationally oriented, day treatment program in Raleigh, North Carolina, served as subjects. We attempted to determine whether demographic and psychosocial characteristics significantly differed among groups of clients who dropped out of, remained in, or refused membership in this community-support program. A variety of demographic, expectancy, psychological, and psychosocial measures were administered to each subject. Most significant was the finding that the subjects' perceived level of help and support from friends was a significant determinant of the level of program participation. Those subjects who refused to participate (refusers) perceived themselves as receiving proportionately less support than did members of the other two groups (dropouts and remainers). 相似文献

Many counselors are currently undergoing a Kuhnian paradigm shift from linear models of behavioral problem conceptualization to systemic conceptual models. As a result, it has become incumbent on counselor-educators to introduce the systems concept of family therapy to their students within a framework that renders it meaningful not only intellectually but also practically. This paper presents one way of doing this successfully with master's level counselors-in-training who have no live families on which to practice. An overview of systems approaches to family therapy is presented along with a seven-stage supervision approach for teaching structural/strategic therapy in limited situations where the supervision of live families is not practical or possible. 相似文献

Practitioners are frequently faced with the need to evaluate the intellectual skills of individuals with very low levels of functioning. Owing to the statistical rarity of these persons, few tests have sufficient range of scores for a detailed analysis of intraindividual differences in performance. This paper describes a method that uses are equivalents and standard scores to recreate the full range of variability in the scores of low-functioning individuals. The method allows for a more complete interpretation of performance that can lead to better educational and therapeutic programming. 相似文献

Early theorists (Skinner, Spence) interpreted discrimination learning in terms of the strengthening of the response to one stimulus and its weakening to the other. But this analysis does not account for the increasing independence of the two performances as training continues or for increases in control by dimensions of a stimulus other than the one used in training. Correlation of stimuli with different densities of reinforcement produces an increase in the behavior necessary to observe them, and greater observing of and attending to the relevant stimuli may account for the increase in control by these stimuli. The observing analysis also encompasses errorless training, and the selective nature of observing explains the feature-positive effect and the relatively shallow gradients of generalization generated by negative discriminative stimuli. The effectiveness of the observing analysis in handling these special cases adds to the converging lines of evidence supporting its integrative power and thus its validity. 相似文献
