空巢老人心理健康的现状及研究述评 总被引:1,自引:0,他引:1
空巢老人的心理健康引起了国内外研究者们的高度关注,逐渐成为一个热点课题.在综合国内外有关空巢老人心理健康的研究文献后发现,目前,学界对空巢老人的界定并不统一;从其心理健康现状来看,空巢综合症是空巢老人各种身心症状的主要体现,主要受社会支持、性别、婚姻状况、经济收入以及其他一些社会人口学因素的影响.虽然对空巢老人心理健康的研究已取得一些成就,但仍存在一些尚待解决的问题,未来研究应从统一空巢老人的涵义,完善研究方法,深入对其自身内部心理因素的探讨及加强跨文化的比较与借鉴等方面来开展. 相似文献

The purpose of this article is to review and evaluate the range of theories proposed to explain findings on the use of geometry in reorientation. We consider five key approaches and models associated with them and, in the course of reviewing each approach, five key issues. First, we take up modularity theory itself, as recently revised by Lee and Spelke (Cognitive Psychology, 61, 152–176, 2010a; Experimental Brain Research, 206, 179–188, 2010b). In this context, we discuss issues concerning the basic distinction between geometry and features. Second, we review the view-matching approach (Stürzl, Cheung, Cheng, & Zeil, Journal of Experimental Psychology: Animal Behavior Processes, 34, 1–14, 2008). In this context, we highlight the possibility of cross-species differences, as well as commonalities. Third, we review an associative theory (Miller & Shettleworth, Journal of Experimental Psychology: Animal Behavior Processes, 33, 191–212, 2007; Journal of Experimental Psychology: Animal Behavior Processes, 34, 419–422, 2008). In this context, we focus on phenomena of cue competition. Fourth, we take up adaptive combination theory (Newcombe & Huttenlocher, 2006). In this context, we focus on discussing development and the effects of experience. Fifth, we examine various neurally based approaches, including frameworks proposed by Doeller and Burgess (Proceedings of the National Academy of Sciences of the United States of America, 105, 5909–5914, 2008; Doeller, King, & Burgess, Proceedings of the National Academy of Sciences of the United States of America, 105, 5915–5920, 2008) and by Sheynikhovich, Chavarriaga, Strösslin, Arleo, and Gerstner (Psychological Review, 116, 540–566, 2009). In this context, we examine the issue of the neural substrates of spatial navigation. We conclude that none of these approaches can account for all of the known phenomena concerning the use of geometry in reorientation and clarify what the challenges are for each approach. 相似文献

Mental rotation, as a covert simulation of motor rotation, could benefit from spatial updating of object representations. We are interested in what kind of visual cue could trigger spatial updating. Three experiments were conducted to examine the effect of dynamic and static orientation cues on mental rotation, using a sequential matching task with three-dimensional novel objects presented in different views. Experiment 1 showed that a rotating orientation cue with constant speed reduced viewpoint costs in mental rotation. Experiment 2 extended this effect with a varied-speed rotating orientation cue. However, no such benefit was observed with a static orientation cue in Experiment 3. These findings indicated that a visually continuous orientation cue is sufficient to elicit spatial updating in mental rotation. Furthermore, there may be differences in the underlying mechanisms of spatial updating on the basis of constant-speed rotating cues and varied-speed rotating cues. 相似文献

Researchers propose social support as one of the factors that may explain the positive relationship often observed between religious involvement and health outcomes. African-Americans are a population that tends to have higher than average levels of religious involvement and are also disproportionately impacted by most health conditions. The present study sought to determine whether social support mediates the role of religious involvement in physical and emotional functioning and depressive symptoms, among a national probability sample of African-Americans (N = 803). Study participants completed telephone interviews. We used structural equation modelling to test hypotheses based on the theoretical model. Findings suggest evidence for a mediating role of belonging and tangible support in the association between religious behaviours and physical functioning as well as depression. There was no mediational role played by appraisal support, or for emotional functioning. Implications for faith-based health promotion interventions are discussed. 相似文献

This article introduces a new affordance framework for humans and human design. Based on previous important concepts in product design–affordance, signifier, and product semantics, the authors propose three new concepts to illustrate how people perceive affordance. According to the model, perceptual probability of affordance is the probability that the public can perceive a certain affordance; perceptual threshold of affordance is the threshold at which affordance can be perceived by a person and changed by perceptual information; and situations, in which interactions between affordances and people exist, are crucial influences on human–affordance interactions. An illustration of the model and suggestions for further research are provided. 相似文献

汉语语句重音的分类和分布 总被引:9,自引:0,他引:9
通过两个独立进行的重音标注实验对汉语语句重音的分类和分布进行了初步探讨。实验l是由60位普通被试参加的音节重音突显度的知觉实验。实验2是由本文三位作者参加的重音类别标注实验,在此实验中语句重音被划分为节奏重音和语义重音。实验2中对于语句重音的分类性标注结果得到了实验l中普通被试对音节重音突显度知觉结果的支持,这说明人们确实能够感知到两种不同类型的重音。实验结果还表明,节奏重音倾向于出现在较大韵律单元内的最末韵律词的末音节上,并且与适当的停延相伴生,语义重音的分布则与语句的韵律结构的关系不大。 相似文献
