This review paper integrates recent structural and functional imaging, postmortem, animal lesion, and neurochemical research about the pathophysiology of autism. An understanding of the neurobiological correlates of autism is becoming increasingly important as more children are diagnosed with the condition and funding for well-targeted interventions increases. Converging evidence suggests that autism involves abnormalities in brain volume, neurotransmitter systems, and neuronal growth. In addition, evidence firmly links autism with abnormalities in the cerebellum, the medial temporal lobe, and the frontal lobe. Potential implications of these findings and suggestions for future research are reviewed.  相似文献

The provision of counselling services for refugee and asylum-seeking patients is relatively new in the UK and their complex needs may present considerable challenges within primary care, where access to specialist support resources is often limited. As far as we know, no previous research has attempted to look at the experiences of the counsellors who do this work. We undertook in-depth interviews with 13 counsellors who provide counselling to refugees in primary care in north London. The findings of this study suggest that counsellors who work in a primary care setting find themselves conflicted, troubled and out of their depth by the experiences, narratives and distress presented by refugee and asylum-seeking patients. They also report an erosion of usual counselling boundaries. Thus, the problems presented by refugees seem to demand approaches which go beyond standard counselling practice and which create ambivalence and uncertainty. These counsellors express feelings of isolation and impotence. The paper concludes with implications for counselling practice and suggestions for further research.  相似文献

Suicide deaths are often viewed as sudden and unexpected. Research examining bereavement responses to suicide are generally set within this conceptual framework. Twenty-two parents were interviewed about their bereavement experience following the suicide death of a young adult son or daughter. Data analyzed using narrative methods revealed the concept of preparedness. Three distinct preparedness narratives were identified, termed turbulent-relief, tragedy, and reflective plots. The data presented here highlights the way in which these different situations influence the resultant grief. Understanding preparedness for suicide assists in explaining the variety of grief responses in parents bereaved in this manner.  相似文献

Depressive symptoms are common and can affect prognosis following acute coronary syndromes (ACS). This study examined the psychological factors, coping, anxiety, and perceived stress associated with depression following ACS. Psychological variables were assessed in 15 females and 66 males (M = 57 years, SD = 12). Repeated measures at 2, 12, and 24 weeks post-ACS compared depression, anxiety, perceived stress, and coping resources as determined by the Cardiac Depression Scale, Beck Depression Inventory-II, State Trait Anxiety Inventory, Perceived Stress Scale, and Coping Resources Inventory. Depression, anxiety, and perceived stress remained high in the depressed group across time. Coping scores at 2 weeks post-ACS predicted depression scores at 24 weeks post-ACS. It appears that trait anxiety and coping resources are related to depressive symptoms post-ACS.  相似文献

Recent studies have reported age deficits in learning sequences that contain subtle sequential regularities (e.g., Curran (1997) Psychological Research, 60(1-2), 24; D. V. Howard et al. (2004) Psychology and Aging, 19(1), 79; Howard, J. H. Jr, & Howard, D. V. (1997). Psychology and Aging, 12(4), 634). This finding is of potential theoretical interest, but the contribution of sequence event timing to this deficit has not been investigated. This study used an alternating serial reaction time task to examine implicit sequence learning in young adults when event timing mimicked that experienced by older adults in previous research. We varied the response-to-stimulus interval directly in Experiment 1 and indirectly by degrading the stimuli to influence response time in Experiment 2. Results indicate that these "aged" young adults learned the higher-order sequence structure implicitly, but they learned less than young controls and more than old adults on some measures of implicit learning in both experiments. In addition, these two different experimental manipulations produced distinct patterns of deficits despite having nearly identical effects on event sequence timing. These findings suggest that event timing alone cannot explain the age deficits observed in high-order implicit sequence learning.  相似文献

Drawing on interviews with 90 young people who have become Witches, we explore the visual media's influence on identity formation and maintenance. Witchcraft is a late modern religion that is highly individualistic and many young people report they have become a Witch without any interaction with other Witches. The rapid growth of interest in this religion among the young since The Craft was first shown provides an important example of the mass media's role in formation of contemporary religious identity. We argue that representations of Witchcraft in the visual mass media (along with other cultural trends such as environmentalism, feminism, and individualism) and cultural resources such as books, Internet sites, and magazines provide a mediated form of social interaction that sustains the plausibility of Witchcraft as a religion. It also helps the young to develop and legitimate their beliefs and practices and develop their Witchcraft persona.  相似文献

Geschwind and Behan (1982) and Geschwind and Galaburda (1985a, 1985b, 1985c) suggested a correlation between brain laterality and immune disorders. To test whether this hypothesis holds true not only for the frequency of immune diseases and circulating autoantibodies, but extends also to cellular immunity, we examined the association between handedness and markers of cellular immunity. Twenty-seven left-handed and 37 right-handed subjects were serologically screened for cellular parameters and 22 left-handed subjects were typed for human leukocyte antigen (HLA). When compared to the right-handers, the left-handed group showed a significant decrease in the inflammatory cell types CD3(+) T cells (total T cells), CD4(+) T cells (T-helper cells), and HLA-Dr (MHC-II, antigen-presenting cells) as well as in the CD19(+) cells (B cells) and CD16/CD57(+) cells (natural killer cells). We assume a relationship exists between cerebral hemispheric specialisation and the immune system not only for humoral but also for cellular immunity, and we discuss the role of the major histocompatibility complex in neurological and immunological development.  相似文献
