Rats obtained access to food twice each 24-hour period. The first session was a work session in which food was available on a progressive-ratio schedule. During the second session, which occurred between 1 and 23 hours after the work session, food was freely available up to a fixed total intake each 24 hours. The situation resembled elements of several real world circumstances, including the choice between continuing to forage in a rapidly depleting patch and waiting for a better patch, and between working now and receiving a guaranteed income later. The purpose of the experiment was to explore the time period over which future access to reward could affect current responding. Contrary to what might be expected from recent theorizing, anticipation of future food delayed by an hour or more after the start of the work session had no effect on current performance. Food intake was high and constant during work sessions except for a prefeeding effect that occurred when the free session closely preceded the next day's work session. Also, an increase in the difficulty of the work schedule increased the amount of work and the maximum price paid for food as if the work session were the only time food was available. The results indicate the importance of considering temporal limits in theories that require animals to integrate input over time to determine the allocation of resources among alternatives. 相似文献

African Americans are at significantly greater risk of hypertension and worse cardiovascular outcomes than other racialized groups, yet hypertension intervention effects remain limited. Thus, it is necessary to understand the potential mechanisms whereby interventions may be more effectively targeted to improve health. Supported by prior research evidence and guided by the Biobehavioral Family Model, this study examined associations between family relationship quality, psychological wellbeing, and self-management behaviors for African Americans with hypertension. Data were pooled from three Midlife Development in the U.S. projects, resulting in a sample of 317 African Americans (63.4% female, Mage = 53.32) with self-reported high blood pressure in the past 12 months. We tested four cross-sectional multiple mediator models, with depressed mood and environmental mastery mediating associations between family strain and exercise, smoking, problematic alcohol use, and stress-eating. Environmental mastery mediated the association between greater family strain and decreased odds of achieving recommended exercise levels; greater odds of reporting problematic alcohol use; and greater stress-eating. Though family strain was associated with depressed mood in each model, this variable did not serve as an indirect pathway to self-management behaviors. Family strain, and the potential pathway identified via environmental mastery, may be a meaningful predictor of disease self-management for African Americans with hypertension. Longitudinal studies are needed to examine directionality and to support intervention trials for improving self-management and hypertension outcomes. 相似文献

This study used an American sample collected over a period of approximately 2 decades (at 3 time points) to examine the temporal relationships between psychological well-being and personality traits (i.e., neuroticism, extraversion, agreeableness, conscientiousness, and openness to experience). The random-intercept cross-lagged panel model was used to separate between-person and within-person sources of variation. Between-person correlations were comparable to those of previous studies. New insights were gained at the within-person level. There were reciprocal relationships between psychological well-being and openness and extraversion, suggesting the joint development of plasticity-related traits and well-being over time. The relationships between psychological well-being and conscientiousness and agreeableness were unidirectional, with psychological well-being preceding these traits. Despite a strong between-person association between neuroticism and psychological well-being, the two were not related at the within-person level. 相似文献

When people face difficult life events, such as cancer or bereavement, they fare better when they receive support. These “experiencers” are likely to seek and receive support from a wide range of people, from close others to acquaintances. Indeed, the social support literature has long acknowledged the value of having a diverse support network. Research suggests that experiencers often perceive “weak ties” (i.e., acquaintances) as sources of support, and that experiencers sometimes prefer to get support from weak ties rather than strong ties. Providing support can be challenging for all kinds of supporters, however weak ties may be more likely than strong ties to allow worries about their inability to provide effective support to stop them from providing any support at all, thus depriving experiencers of opportunities for additional support. In this paper, we focus on the fact that often the provision of support occurs via a social interaction. We draw on the social psychology literature on minimal social interactions to suggest reasons why potential weak tie supporters might doubt their ability to provide effective support, and to generate advice to encourage potential supporters to reach out. Finally, we suggest future areas of research, with the ultimate goal of helping to expand the support that is available for people experiencing difficult life events. 相似文献

The future of pediatric psychology is reviewed and placed in brief historical context in relation to children's psychological health care. Contemporary trends affecting the delivery of psychological services, research, and clinical training are highlighted, with suggestions for future development. Pediatric psychology is a child-based, developmentally-focused multidisciplinary practice directed toward psychosocial and neuropsychological issues of health and illness in children and youth. Pediatric psychologists need to develop strong professional identities as health care psychologists combined with a collegial and collaborative arrangement with physicians to ensure the future growth and development of pediatric psychology in the next century as a major vehicle to promote children's health care. 相似文献

Tested a theoretical model on the effects of social role identity, illness intrusion, and competence on psychological well-being among 109 low-income Latinas with arthritis. All six roles studied were rated as highly important identities. Sex-role nontraditionalism was associated with less importance of the homemaker, mother, and grandmother roles. Negative affect increased as a function of intrusions into valued identities. Having important role identities contributed to feelings of competence (i.e., self-esteem and self-efficacy), which in turn, contributed to psychological well-being. Competence also mediated the effects of pain, identity, and illness intrusions on psychological well-being. Results suggest competence processes play an important role in well-being. 相似文献

In analytical psychology, ego is associated with consciousness and the masculine principle. Although die feminine principle generally characterizes the unconscious, it was not assigned a psychic structure equivalent to the ego. This paper proposes a model of the psyche where self and ego are the major modes of psychic experience. The self as the 'being' mode represents the feminine principle and functions according to primary process; the ego represents 'doing', the masculine principle and secondary process. Feminine and masculine principles are considered to be of equal significance in both men and women and are not limited to gender.
Jung's concept of the self is related to the Hindu metaphysical concepts of Atman and Brahman, whose source was the older Aryan nature-oriented, pagan religion. The prominence of self in analytical psychology and its predominantly 'feminine' symbolism can be understood as Jung's reaction to the psychoanalytic emphasis on ego and to Freud's 'patriarchal' orientation. In Kabbalah, a similar development took place when the feminine principle of the Shekinah emerged in a central, redemptive role, as a mythic compensation to the overtly patriarchal Judaic religion.
In the proposed model of the psyche neither ego nor self represents the psychic totality. The interplay of both psychic modes/principles constitutes the psyche and the individuation process. 相似文献

Two families, in which the children had been placed in foster care due to abuse and neglect by parents who had disabilities, were studied. In the first case, the mother was instructed in skills that our assessment suggested were important for her child's survival. The mother readily acquired and applied these skills, a fact reflected both in changes in her behavior and in changes in the child's well-being. In the second case, the parent's incremental resumption of child custody was made contingent upon completion of relevant parenting tasks. Initially, improvements in the completion of such tasks were evident, but over time and with the onset of militating factors, no further progress was made and all parental rights were terminated. The implications of these cases for behavior analysis and the effort to reunite and preserve families are discussed. 相似文献
