In this study we assessed habituation and sensitization of the acoustic startle response (ASR) to discern whether intense,
inescapable stress affects nonassociative learning differently in male and female rats. Rats were inescapably stressed 2 hours
per day over 3 consecutive days. ASR magnitudes were measured at several times post-stress (1, 4, 8, and 15 days after cessation).
Females generally showed greater ASR magnitudes (compared to males), but both sexes exhibited short and long-term habituation
across the testing days. ASR magnitudes were only affected by stress in male subjects. The effect in males was an increase
in short-term sensitization of the ASR on post-stress day-4. The results suggest that stressed males and females react differently
to ASR testing, in that stress males appear to develop an exaggerated ASR response over repeated test sessions due to short-term
sensitization. The source of the short-term sensitization is discussed with regards to possible stress-induced enhanced contextual
learning during ASR testing on post-stress day-1. 相似文献

We examined whether the functionality of spatial relations affects the construction and memory of information in situation models. A functional relationship involves the interaction of entities that is implied by either typical use or contextual demands. Previous research has shown that spatial relations are less likely to be encoded during comprehension unless there is extensive prior knowledge, explicit instructions to attend to spatial information, or a clear emphasis on spatial information. If the construction of a situation model is guided by a need to understand the functional structure of a situation, then functional spatial relations should be more likely to be encoded. The results of our study showed that sentences with functional spatial relations were read faster and remembered better in both recall and recognition tests than sentences with nonfunctional spatial relations. 相似文献

The relationship between lesion location and neuropsychiatric sequelae in stroke patients has been extensively studied. Emotional disorders associated with right hemisphere stroke include depression, anxiety, anger, and/or mania. Pharmacotherapy, electroconvulsive therapy, and/or psychotherapy are common treatments for these disorders. This article reviews the clinical presentations of seven right hemisphere stroke patients. The treatment rationale and course of treatment are described for two of these patients. The aims of this paper are to explore the appropriateness of various assessment tools and treatment modalities for stroke patients as well as to demonstrate the techniques of psychotherapy as applied to the two cases featured in this article. Specific factors that may significantly influence treatment outcome, such as lesion location and degree of cognitive impairment, are considered. 相似文献

This paper outlines the ways in which an individual’s notions of sexuality are challenged by immigration. It describes four basic facets of sexuality and the ways in which each are rooted in culture. These include (1) the relative importance of sexuality in daily life; (2) potential or overt homosexuality; (3) marriage—whether based on arrangement or love; and (4) cross-cultural romantic and marital relationships. Immigration can stir up conflicts in each of these realms and lead to defensive retreat into familiar customs or a counterphasic plunge into new cultural avenues. Ideally, it would lead to a working-through of these conflicts and subsequent growth in the immigrant’s understanding of his or her sexual self. 相似文献
