A sample of 382 Israeli soldiers who developed combat stress reactions (CSR) during the 1982 Israel-Lebanon War were compared with groups of carefully matched controls who did not develop CSR. Lack of social support from officers was found to be related to greater feelings of loneliness and greater likelihood of CSR in soldiers. Lack of social support from buddies was found to be related to greater loneliness. Intensity of battle was also found to be related to greater feelings of loneliness and increased likelihood of CSR. A path model was tested and supported. The model suggests that battle intensity and officer support lead to CSR directly and indirectly by causing increased feelings of loneliness. Possible cognitive and psychodynamic explanations for the findings are offered. The limitations of making causal statements from retrospective perceptions is discussed. 相似文献

Four-, five-, and six-year-old Chinese and Canadian boys and girls were presented a series of 11 graphic models and were asked to draw them. Supporting Piaget's theory, the data indicated that drawing performance on the topological dimension was better than the performance on the Euclidean dimension, and that there were neither gender nor cultural differences in performance. The research offers strong support for a main effect of biological or maturational factors as the foundation for the developmental influences in the acquisition of spatial conceptions. 相似文献

Subjects were required to discriminate complex random polygons which had the same global shapes but differed in local contour characteristics. Discrimination was most often successful when local contour features comprised a few long line segments or when they were relatively complex. Local contour features of intermediate sized elements and intermediate complexity played a smaller role in discrimination. Presentation time and interstimulus interval effects, and their interaction were observed. A two-factor explanation was offered for the effect of the contour variable. 相似文献

The role of location indexes in spatial perception: a sketch of the FINST spatial-index model 总被引:4,自引:0,他引:4
Z Pylyshyn 《Cognition》1989,32(1):65-97
This paper hypothesizes a resource-limited mechanism, called a FINST, for individuating or indexing visual features, as distinct from encoding their type or location. FINSTs have the property that they index features in a way that is transparent to their retinal location, and hence under certain conditions succeed in "pointing to" scene locations. The basic assumption is that no operation upon sets of features can occur unless all the features to which the operation applies are first FINSTed. A number of applications of this hypothesis are explored in this paper, including applications to phenomena such as the spatial stability of visual percepts, the ability to track several independently moving targets in parallel, the ability to detect a class of spatial relations requiring the use of "visual routines", various mental imagery phenomena, and the ability to encode complex shapes for recognition. In addition, the possibility is examined that such indexes might be used to bind perceived locations to arguments in motor commands, thereby allowing some forms of perceptual-motor coordination. Several additional assumptions are introduced for this purpose, including the postulation of other indexes (called ANCHORS) for non-visually sensed locations. It is assumed that ANCHORS can be bound to FINSTs, thus allowing cross-referencing of visually detected locations to locations given within a proprioceptive or motor-command frame of reference. 相似文献

Dual-process models of the mind, as well as the relation between analytic thinking and religious belief, have aroused interest in recent years. However, few studies have examined this relation experimentally. We predicted that religious belief might be one of the causes of prejudice, while analytic thinking reduces both. The first experiment replicated, in a mostly Muslim sample, past research showing that analytic thinking promotes religious disbelief. The second experiment investigated the effect of Muslim religious priming and analytic priming on prejudice and showed that, although the former significantly increased the total prejudice score, the latter had an effect only on antigay prejudice. Thus, the findings partially support our proposed pattern of relationships in that analytic thinking might be one of the cognitive factors that prevents prejudice, whereas religious belief might be the one that increases it. 相似文献

The literatures on violence among young men and young women have highlighted the importance of situational context. However, few studies have compared disputes that do not result in violence with those that do, and even fewer have been positioned to investigate the role situational context may play across gender in accounting for these outcomes. Drawing on recent scholarship on gender and violence, this research explores the situational contexts of youth conflicts among African-American adolescent boys and girls. Using a large sample of narrative accounts of 153 violent and nonviolent conflicts, we examine how youth describe the issues of contention in their conflicts, how these relate to the situational contexts in which conflicts emerge, and similarities and differences in the antecedents, contexts, and extent of male and female violence. 相似文献

We report on a novel phenomenon, that is a high-strain-induced reverse martensitic transformation in an ultrafine-grained Ti–36Nb–2Ta–3Zr (wt.%) alloy processed by equal channel angular pressing (ECAP) at room temperature. Our results show that a martensitic transformation from body-centred cubic β matrix to orthorhombic α″ martensite occurs under low-strain ECAP conditions and that a large portion (~34%) of martensite transforms into a matrix phase (i.e. reverse martensitic transformation) with increasing ECAP strain to a high value of 4 (i.e. 6 passes) with a corresponding reduction in the α″-lath thickness and a refinement of grain size in the matrix phase. 相似文献
