The psychological autopsy (PA) is a systematic method of assessing the psychological and contextual circumstances preceding suicide. The method requires interviews with one or more proxy respondents (i.e., informants) of suicide decedents. Procedural challenges that need to be addressed to conduct PA interviews are described in this article and recommendations for meeting these challenges in future PA investigations are made. Procedures addressed include determining the timing of PA interviews after suicide, designing the structure and flow of interviews, selection of proxy respondents, integrating interview data with information gathered from records, and selecting and training interviewers. This methodological article is the second in a two-part series-the first article focused on interview content. 相似文献

Repetitive thought (RT) - attentive, prolonged, or frequent thought about oneself and one's world - plays an important role in many models of psychological and physical ill health (e.g., rumination and worry), as well as models of recovery and well-being (e.g., processing and reminiscing). In these models, repetitive thought is typically treated as stable or trait-like. In contrast, episodic RT reflects what people have "on their minds" at a particular point in time. In four studies, young women (N=94), college students (N=166), first-year law students (N=73), and older adults (N=174) described their episodic RT, which was then rated for qualities including valence, purpose, and theme. Episodic RT valence was associated with mood and depressive symptoms both between (Studies 1-4) and within people (Studies 3-4), and it mediated the effects of dispositional coping through emotional approach (Study 1). The effect of episodic RT valence in turn was moderated by other properties of episodic RT, including purpose, "trait" valence, and theme (Studies 1-4). The study of episodic RT complements that of trait RT and allows for observations of how RT and psychological adjustment change in concert and in context, as well as examining how the RT qualities that are not reflected in trait measures affect adjustment. 相似文献

Early studies of memory-impaired patients with medial temporal lobe (MTL) damage led to the view that the hippocampus and related MTL structures are involved in the formation of long-term memory and that immediate memory and working memory are independent of these structures. This traditional idea has recently been revisited. Impaired performance in patients with MTL lesions on tasks with short retention intervals, or no retention interval, and neuroimaging findings with similar tasks have been interpreted to mean that the MTL is sometimes needed for working memory and possibly even for visual perception itself. We present a reappraisal of this interpretation. Our main conclusion is that, if the material to be learned exceeds working memory capacity, if the material is difficult to rehearse, or if attention is diverted, performance depends on long-term memory even when the retention interval is brief. This fundamental notion is better captured by the terms subspan memory and supraspan memory than by the terms short-term memory and long-term memory. We propose methods for determining when performance on short-delay tasks must depend on long-term (supraspan) memory and suggest that MTL lesions impair performance only when immediate memory and working memory are insufficient to support performance. In neuroimaging studies, MTL activity during encoding is influenced by the memory load and correlates positively with long-term retention of the material that was presented. The most parsimonious and consistent interpretation of all the data is that subspan memoranda are supported by immediate memory and working memory and are independent of the MTL. 相似文献

Pigeons were trained to discriminate between stimuli constructed using five orthogonal two-valued features. The stimuli consisted of stylized monochrome drawings of seeds. Two different training procedures (conditional and simultaneous discrimination) were used. In the first two experiments, the discrimination required was between polymorphous categories, in which a positive stimulus was defined as one in which three or more of the five features took their positive values. Discrimination in both experiments was imperfect; the pigeons' behaviour only came under the control of a subset of the available features (one to three in Experiment 1, three or four in Experiment 2). In Experiment 3, single features had to be discriminated, while the remaining features varied. It was found that all five features of the “seed” stimuli could be discriminated, but one of them was exceptionally difficult. The results show that pigeons do not reliably use all the features available to them when making category discriminations. This casts doubts on feature analysis as a basis for the excellent performance pigeons show when required to discriminate between categories of natural objects. 相似文献

The conflicting views on Tourette's syndrome (TS) and its management in children put forward in the November 1985 issue of Journal of Family Therapy (Nunn, 1985; Prata & Masson, 1985) and the Editorial in the same issue prompt us to report a case. A twelve-year-old boy with TS managed on interactional lines snowed changes more modest than those achieved by Prata and Masson, and we address some of the issues raised by Nunn in his critique of their paper. 相似文献
