Despite long-established roots in experimental psychophysiology and psychosomatic medicine, behavioral medicine and health psychology have only recently emerged as recognized, highly visible disciplines within medicine and the behavioral sciences. The rapid development of these fields has resulted partly from important scientific advances in the biomedical and behavioral sciences and partly from changing societal concerns and values. The latter include a greater preoccupation with individual self-expression and self-fulfillment, a decline in respect for authority per se, and an increased skepticism about social institutions. Coupled with these changes has been an increasing desire to take responsibility for one's own life and, in matters of health, of one's own body. The ways in which scientific advances and social changes have influenced the shape of contemporary behavioral medicine and health psychology are explored with the aid of two illustrations: the growth of a developmental perspective in behavioral medicine and health psychology; and work and health, including the effects of job stress and unemployment. Finally, the author stresses the need for a greater sense of community and concern for others, if we are to succeed in creating a growth-enhancing, health-producing climate for society as a whole and for each of us as individuals. 相似文献

An 11-parameter Markov model of stages of learning, which was developed by Brainerd et al., will be presented. The focus will be on parameter interpretation in terms of long-term memory (LTM) processes. Next the model will be used to examine the contribution of these various LTM processes to Schooltype and Age differences in a word-pair memorization experiment. Subjects were 8 and 11-year-old normal-achieving (NA) children from regular elementary schools and 8 and 11-year-old children from special schools for learning disabled (LD) children. One of the main conclusions is that the Schooltype × Age interaction which was demonstrated for traditional performance measures, can be explained by LD children's little developmental progress in storage processes and deviations from normal development in aspects of the acquisition of retrieval algorithms. No deficiences were, however, detected in the LD children's rerention ability early in the task, and in the so-called heuristic retrieval operations. 相似文献

Mechanisms of the relation between perinatal problems, early childhood illness, and psychopathology in late childhood and adolescence 总被引:6,自引:0,他引:6
Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks. 相似文献

Depressed mothers' judgments about their children: an examination of the depression-distortion hypothesis 总被引:5,自引:0,他引:5
The belief that depressed mothers have distorted perceptions of their children's problems has gained considerable currency in recent years. The empirical basis for this belief at present amounts to little more than reliable demonstrations that depressed mothers tend to report more behavior problems in their children than do nondepressed mothers. An obvious alternative to the distortion interpretation is that depressed mothers are accurate about their children's behavior problems. We examined these competing models by comparing teachers' ratings of children with ratings provided by their mothers, who varied on the dimensions of depressed mood, depressed clinical state, and history of depression. Mothers' and teachers' ratings yielded substantially similar portraits of child behavior problems at the group level, with children of in-remission and in-episode mothers manifesting significantly higher levels of behavior problems than children of control mothers. Moreover, agreement between mothers and teachers was in the moderate range for all index groups and did not differ significantly from the mean level of mother-teacher agreement reported by other investigators based on unselected samples. The limitations of these findings and of earlier reports for assessing a depression----distortion influence on mothers' ratings of their children are considered. 相似文献

Genetic and environmental origins of individual differences in masculine and feminine personality attributes were investigated in a sample of 38 monozygotic and 32 dizygotic twin pairs (total N = 140) during pre- and early adolescence. Self-report measures of both masculine and feminine characteristics were obtained for each child using 2 standardized instruments: the Children's Personality Attributes Questionnaire (CPAQ) and the Adolescent Self-Perception Inventory (ASPI). Multivariate biometrical analyses revealed significant genetic influences in all measures, accounting for 20%-48% of the observed variation in each. Environmental influences, which explained the remaining 52%-80% of variance in masculinity and femininity, were apparently specific to each individual and not shared by members of the same twin pair. The results underscore the importance of considering both genetic and environmental factors in gender-role development, particularly in studies of family resemblance. 相似文献

One hundred and eighty-one teacher training students sat three attitude measuring instruments to investigate the relationships between attitudes to self, attitudes to others and attitudes to educational practices. Clinical studies within the ambit of Rogerian psychotherapy suggest that a relationship between self and other attitudes should be positive. Substantial and statistically significant positive correlations, in the order of p<0.01, emerged consistently in this study between attitudes to self and attitudes to a range of others and to progressive child centred educational practices. Self acceptance level would seem to be an index of attitudes to a wide range of others. This relationship provides a principle of utmost importance for human relationships since the application of psychological processes to enhance the self concept should facilitate as a corollary a decrease in interpersonal tensions and inter group conflict. This relationship is of particular consequence in the teaching context since teaching is a sharing of self with others. The results of the study suggest that those with low self acceptance prefer (p<0.01) to avoid close encounters with pupils and prefer a more traditional formal teaching style. 相似文献
