近几年诸多研究者认为阅读障碍是由于视觉系统巨细胞功能缺陷引起的。他们从对比度敏感性研究、巨细胞抑制功能研究与视觉运动知觉功能的研究结果中得到了支持证据。就这个问题的研究进行综述,表明不论是巨细胞功能缺陷理论的支持者还是反对者,都从巨细胞的对比度敏感性、视觉运动知觉与巨细胞抑制功能上得到了一些研究结果的支持。巨细胞功能缺陷理论的支持者还从阅读障碍的神经生理学研究和阅读的脑功能研究中得到了一些支持性的证据。新的研究结果揭示了巨细胞系统缺陷理论与阅读之间的关系以及巨细胞系统缺陷理论的应用价值。在巨细胞系统缺陷理论的进一步研究中,还需要统一实验方法与实验标准以获得更多的证据,同时需要有新的方法来有效区分小细胞系统与巨细胞系统 相似文献

This study examined the influence of feminist attitudes on self-objectification, habitual body monitoring, and body dissatisfaction in middle age and older women. The participants were 138 European American heterosexual women ranging in age from 40 to 87 years old. Consistent with previous research, self-objectification and habitual body monitoring were positively correlated with body dissatisfaction and, self-objectification and habitual body monitoring remained stable across the lifespan. While age did not moderate the relationship between self-objectification and body dissatisfaction, age was found to moderate the relationship between habitual body monitoring and body dissatisfaction such that the relationship was smaller for older women than for middle-aged women. Interestingly, feminist attitudes were not significantly correlated with body dissatisfaction, self-objectification, or habitual body monitoring, and endorsement of feminist attitudes was not found to moderate the relationship between self-objectification or habitual body monitoring and body dissatisfaction. Potential implications for older women are discussed. 相似文献

From 1957 through the mid-1970s, John Bowlby, one of the founders of attachment theory, was in close personal and scientific
contact with Harry Harlow. In constructing his new theory on the nature of the bond between children and their caregivers,
Bowlby profited highly from Harlow’s experimental work with rhesus monkeys. Harlow in his turn was influenced and inspired
by Bowlby’s new thinking. On the basis of the correspondence between Harlow and Bowlby, their mutual participation in scientific
meetings, archival materials, and an analysis of their scholarly writings, both the personal relationship between John Bowlby
and Harry Harlow and the cross-fertilization of their work are described.
Frank C.P. van der Horst is a PhD student and Lecturer at the Centre for Child and Family Studies at Leiden University, The Netherlands. The work presented in this special issue is part of his doctoral thesis on the roots of Bowlby’s attachment theory. The defence of this thesis, titled John Bowlby and ethology: a study of cross-fertilization, is scheduled for early 2009. Helen A. LeRoy recently retired from the Harlow Primate Lab at the University of Wisconsin-Madison after working there for nearly half a century. During that time, she worked closely with Harry Harlow from her arrival in 1958 until his retirement in 1974. She was Harlow’s executive assistant and was his help and stay in the editing of the Journal of Comparative and Physiological Psychology. René van der Veer is Professor of History of Educational Thinking at Leiden University, The Netherlands. His research addresses the work of key educational thinkers such as Gal’perin, Janet, Piaget, Vygotsky, Werner, and Wallon. In a longer study the origin of the idea of the social mind was traced. He is on the Editorial Board of Integrative Psychological and Behavioral Sciences. 相似文献

On the basis of personal reminiscences an account is given of Harlow’s role in the development of attachment theory and key
notions of attachment theory are being discussed. Among other things, it is related how Harlow arrived at his famous research
with rhesus monkeys and how this made Harlow a highly relevant figure for attachment theorist Bowlby.
Stephen J. Suomi is Head of the Laboratory of Comparative Ethology at the National Institute of Child Health and Human Development (NICHD) in Bethesda, Maryland. He became well-known for his research on the biobehavioral development of rhesus monkeys and other nonhuman primate species. He authored over 300 published articles in refereed scientific journals and chapters in edited volumes. Among his current interest are the interactions between genetic and environmental factors that shape individual developmental trajectories.

Drawing on the mentoring, education, and social psychology literatures, this longitudinal study examines how the persistence of developmental relationships from an elite graduate school influences subjective career outcomes during early career. Participants (n = 136) were surveyed about their developmental networks—a group of individuals who take an active interest in and action to advance a focal individual’s career—and subjective career outcomes over the 10 years (1996-2006) post graduation. Results show that although receiving mentoring from one’s entire developmental network was positively related to career-related self-efficacy and perceptions of career success, this was not the case for ties retained from graduate school. Continuing to receive mentoring support from developers from graduate school and further, from peers from graduate school, was negatively related to perceptions of career success. These findings offer insight into the dynamics and potentially negative consequences of developmental networks and highlight the significance of social comparison during early career. 相似文献

Patients with schizophrenia have disproportionately high rates of emergency medical service use, likely contributing to the high cost this illness places on society. The aim of this study was to examine the impact of a theory-based, behavioral intervention on immediate and long-term use of emergency medical services. Older patients with schizophrenia (n=240) were randomized to receive either a behavioral, skills-building intervention known as Functional Adaptation and Skills Training (FAST) or a time-equivalent attention-control condition (AC). Logistic regression analyses indicated that AC participants were nearly twice as likely to use emergency medical services in general (OR=2.54; p=0.02) and emergency psychiatric services in particular (OR=3.69; p=0.05) during the active intervention phase of the study. However, there were no differences between the interventions in terms of emergency service use during the long-term follow-up phase of the study (i.e., 6-18 months post-baseline). The FAST intervention appears efficacious for reducing the short-term risk of using emergency medical services. However, the long-term efficacy of the FAST intervention appears less clear. Future studies may want to provide more powerful maintenance sessions to encourage continued use of skills in patients' real-world settings. 相似文献

When non-informative peripheral cues precede a target defined by a specific feature, cues that share the critical feature will capture attention while cues that do not will be effectively ignored. We tested whether different attentional control sets can be simultaneously maintained over distinct regions of space. Participants were instructed to respond only to specific colored targets at specific locations. Most trials included non-predictive cues whose location and/or color were either congruent or incongruent with the spatial and/or color properties of the impending target. We observed contingent capture only for cues that were consistent with the attentional control set applied to that region of space. This is the first demonstration that separate attentional control sets can be simultaneously maintained at distinct spatial locations, with implications for the flexibility of endogenous control over automatic attentional orienting. 相似文献

Similarity is central in human cognition, playing a role in a wide range of cognitive processes. In three studies, we demonstrate that subjective similarity may change as a function of temporal distance, with some events seeming more similar when considered in the near future, while others increase in similarity as temporal distance increases. Given the ubiquity of inter-temporal thought, and the fundamental role of similarity, these results have important implications for cognition in general. 相似文献
