Four observers completed identification and categorization tasks. Learning and attention processes were examined by applying general recognition theory (F. G. Ashby & J. T. Townsend, 1986), which separates perceptual, decisional, and attentional processes. Learning led to decision regions that became more nearly optimal. Learning had little effect on perceptual processes in identification and decisional integration categorization tasks but affected perceptual processes in decisional selective attention categorization tasks, leading to perceptual selective attention. These findings suggest that (a) identification and categorization invoke decision strategies that are localized in the striatum (F. G. Ashby, E. M. Waldron, W. W. Lee, & A. Berkman, 2001) and (b) perceptual and decisional attention systems exist and are mediated by distinct brain structures (M. I. Posner & S. E. Petersen, 1990). 相似文献

The practice of genetic counseling is in need of evidence-based theoretical frameworks. Although strategies used in genetic counseling are increasingly evidence-based, the field of genetic counseling does not have a generally accepted theoretical basis for development of therapeutic interventions. We know very little about (1) what actually happens in genetic counseling and (2) the impact it has on clients and their families. A number of researchers have used a variety of approaches in an attempt to introduce some theoretical basis for genetic counseling research and practice. Other workers have used experience in their clinical practice to write theoretically about the kinds of processes that might be going on in and around genetic counseling. However, there are few studies to date, which have attempted to build theory modeling the psychosocial processes that take place in and around the genetic counseling clinic using empirical data. This paper describes a methodology (grounded theory) that is designed specifically to build theory about psychosocial processes from a strong evidence base, and explains how it can contribute to the development of practice in genetic counseling. 相似文献

According to Steele (1997), negative stereotypes about intellectual abilities can act as a threat that disrupts the performance
of students targeted by bad reputations. Previous research on stereotype threat has showed that on a stereotype-relevant test,
stigmatized group members (e.g., African Americans) performed worse than others on an intellectual verbal task. However, when
the instructions accompanying the test did not create stereotype threat, stigmatized group members' performance was equal
to that of other participants. In this paper, we present studies documenting the effect of stereotype threat and discuss ways
to counter it. Two strategies derived from Self-Categorization Theory (Turner & Oakes, 1989) and Self-Affirmation Theory (Steele,
1988) are presented, tested, and discussed.

The abuse of alcohol and other substances by mothers raising adolescent children has serious adverse effects on family functioning
and youth outcomes, and on mothers’ own health and adaptation. Mothers who are also HIV-infected face additional challenges.
In the present report, we describe a multi-session intervention conducted in individual sessions for mothers with alcohol
and other substance use problems who are raising adolescent children. We outline the primary components of the intervention
and include case studies and examples of exercises and tools. We found that engagement with the intervention and high rates
of attendance were facilitated by tapping into mothers’ desires to improve their relationships with their adolescent children,
the use of a harm reduction approach toward substance use, and intensive outreach. We also discuss lessons learned in the
course of implementing and evaluating the intervention. 相似文献

Being teased about one’s physical appearance in childhood has been found to have a strong impact on the way in which adolescent
and adult women perceive their bodies. Teasing is also strongly related to self-esteem in children. However, little is known
about the impact of teasing on the development of body image in childhood. Through a quantitative study of the experience
of being teased and body image satisfaction in a group of 431 primary aged children, we examined the prevalence, type and
impact of teasing on children’s perceived body image satisfaction. The results of our study indicated that many children,
especially those who are over or underweight experience being teased. This experience does have a negative impact on children’s
body image. This is especially significant for young girls and boys who are overweight. Underweight young boys also suffer
negatively from this experience. It is important for parents and others to understand that what may be perceived as friendly
banter with their children may not necessarily be innocuous. Further research exploring the concept and construct of teasing
in childhood is warranted. 相似文献

Unique pathways to resilience across cultures 总被引:3,自引:0,他引:3

An international mixed methods study of resilience of 14 sites in eleven countries identified seven tensions that youth resolve in culturally specific ways. Resolution of these tensions is foundational to experiences of resilience. This paper reports on the qualitative findings from interviews with 89 youth. Results support a culturally embedded understanding of positive youth development that better accounts for young people's resilience in western and non-western countries. Specifically, the seven tensions identified include: access to material resources, relationships, identity, cohesion, power and control, social justice, and cultural adherence. Findings show that no one pattern in the resolution of these tensions predicts resilience better than another. A case study of a Palestinian boy demonstrates the intersection of the seven tensions and the uniqueness of their resolution. The implications of this work for interventions is discussed. 相似文献

Relations between night waking in infants and depressive symptoms in their mothers at 6 months postpartum were examined using the data from the National Institute for Child Health and Human Development Study of Early Child Care. Although more depressive symptoms were only weakly correlated with a higher frequency of infant waking, longer wake times, and more total time awake, the rate of clinically significant depression scores was about double in mothers of chronically waking infants in comparison with mothers whose infants did not awaken during the night. The value of comparing subgroups to elucidate relations identified through correlations is discussed. 相似文献
