The authors explore the extent to which eating disorders, specifically anorexia nervosa (AN) and bulimia nervosa (BN), represent culture-bound syndromes and discuss implications for conceptualizing the role genes play in their etiology. The examination is divided into 3 sections: a quantitative meta-analysis of changes in incidence rates since the formal recognition of AN and BN, a qualitative summary of historical evidence of eating disorders before their formal recognition, and an evaluation of the presence of these disorders in non-Western cultures. Findings suggest that BN is a culture-bound syndrome and AN is not. Thus, heritability estimates for BN may show greater variability cross-culturally than heritability estimates for AN, and the genetic bases of these disorders may be associated with differential pathoplasticity. 相似文献

One of the major difficulties in presenting an international perspective on delusional disorders and their impact on offending or violent behaviour is that no two legal systems are quite the same, and there are substantial differences between some of them; in addition, there is international variation in relevant service provision or use. We therefore invited several experts practising in forensic mental health services or the law to consider the following case and to use relevant literature, statute and case law to draw out similarities and differences in process and management of the following case. Annie Smith is not a real person; the things that happened really occurred. 相似文献

Previous studies have reported that imagination can induce false autobiographical memories. This finding has been used to
suggest that psychotherapists who have clients imagine suspected repressed memories of childhood sexual abuse may, in fact,
be inducing false memories for the imagined events. In this study, at Time 1 and then, 2 weeks later, at Time 2, 145 subjects
rated each of 20 events on the Life Events Inventory as to whether each had occurred to them in childhood. One week after
Time 1, the subjects were told that 2 target events were plausible and 2 were implausible. They were then asked to imagine
1 plausible and 1 implausible target event. Plausibility and imagining interacted to affect occurrence ratings; whereas imagining
plausible events increased the change in occurrence ratings, imagining implausible events had no effect on occurrence ratings. 相似文献

Over the past 20 years, there has been an increased emphasis on health promotion, including prevention activities related to vision and oral health, for the general population, but not for individuals with intellectual disability (ID). This review explores what is known about the prevalence of vision problems and oral health conditions among individuals with ID, presents a rationale for the increased prevalence of these conditions in the context of service utilization, and examines the limitations of the available research. Available data reveal a wide range of prevalence estimates for vision problems and oral health conditions, but all suggest that these conditions are more prevalent among individuals with ID compared with the general population, and disparities exist in the receipt of preventive and early treatment for these conditions for individuals with ID. Recommendations for health improvement in these areas include better health planning and monitoring through standardized population-based data collection and reporting and increased emphasis on health promotion activities and early treatment in the healthcare system. 相似文献

Over the past few decades a large body of work from developmental neurobiology has shown that mammalian brain development is the product of dynamic and adaptive processes operating within highly constrained, but continually changing, biological and environmental contexts. The recent study of children with prenatal focal brain injury supports this dynamic view of development for humans. Children's injuries often affect substantial portions of one cerebral hemisphere, resulting in damage that would compromise cognitive ability in adults. However, longitudinal behavioral studies of this population have revealed only mild deficits. It is suggested here that children's capacity for adaptation reflects normal developmental processes operating against a backdrop of serious neural perturbation. Data from three behavioral domains--linguistics, spatial cognition and affective development--illustrate this complex profile of change. 相似文献

Belief-desire reasoning as a process of selection 总被引:7,自引:0,他引:7
Human learning may depend upon domain specialized mechanisms. A plausible example is rapid, early learning about the thoughts and feelings of other people. A major achievement in this domain, at about age four in the typically developing child, is the ability to solve problems in which the child attributes false beliefs to other people and predicts their actions. The main focus of theorizing has been why 3-year-olds fail, and only recently have there been any models of how success is achieved in false-belief tasks. Leslie and Polizzi (Inhibitory processing in the false-belief task: Two conjectures. Developmental Science, 1, 247-254, 1998) proposed two competing models of success, which are the focus of the current paper. The models assume that belief-desire reasoning is a process which selects a content for an agent's belief and an action for the agent's desire. In false belief tasks, the theory of mind mechanism (ToMM) provides plausible candidate belief contents, among which will be a 'true-belief.' A second process reviews these candidates and by default will select the true-belief content for attribution. To succeed in a false-belief task, the default content must be inhibited so that attention shifts to another candidate belief. In traditional false-belief tasks, the protagonist's desire is to approach an object. Here we make use of tasks in which the protagonist has a desire to avoid an object, about which she has a false-belief. Children find such tasks much more difficult than traditional tasks. Our models explain the additional difficulty by assuming that predicting action from an avoidance desire also requires an inhibition. The two processing models differ in the way that belief and desire inhibitory processes combine to achieve successful action prediction. In six experiments we obtain evidence favoring one model, in which parallel inhibitory processes cancel out, over the other model, in which serial inhibitions force attention to a previously inhibited location. These results are discussed in terms of a set of simple proposals for the modus operandi of a domain specific learning mechanism. The learning mechanism is in part modular--the ToMM--and in part penetrable--the Selection Processor (SP). We show how ToMM-SP can account both for competence and for successful and unsuccessful performance on a wide range of belief-desire tasks across the preschool period. Together, ToMM and SP attend to and learn about mental states. 相似文献
