A method is presented which uses an on-line computer to control the spatial phase and movement of an electronically generated grating display for visual experiments. This technique minimizes CPU overhead and is inexpensive. The method is compared with several other schemes for controlling grating phase and movement. 相似文献

Two independent surveys from opposite ends of the globe, the UK and New Zealand, completed by families which include a family member accused of sexually abusing a child, have produced remarkably similar results. The majority of accusations were made by well-educated white women about their biological fathers and/or their mothers, based upon memories often recovered within a therapeutic context, many years after the incidents were supposed to have taken place. Accusations included disproportionately high rates of rape, bizarre sexual behaviours and satanic ritual abuse in both surveys. © 1997 by John Wiley & Sons, Ltd. 相似文献

Rett Syndrome is unlike any other pediatric neurologic disease, and its clinical-pathologic correlation can not be defined with standard histology techniques. Based on hypotheses suggested by careful clinical observations, the nervous system of the Rett child has been explored utilizing morphometry, golgi preparations, computerized tomography, magnetic resonance imaging, chemistry, immunocytochemistry, autoradiography, and molecular biologic techniques. From these many perspectives we conclude that Rett syndrome is not a typical degenerative disorder, storage disorder, nor the result of gross malformation, infectious or neoplastic processes. There remain regions of the brain that have not been studied in detail but the available data suggest that the neuropathology of Rett syndrome can be summarized as follows: the Rett brain is small for the age and the height of the patient; it does not become progressively smaller over three to four decades; it has small dendritic trees in pyramidal neurons of layers III and V in selected lobes (frontal, motor, and temporal); it has small neurons with an increased neuronal packing density; it has an immature expression of microtubular protein-2 and cyclooxygenase; it exhibits a changing pattern of neurotransmitter receptors with an apparent reduction in many neurotransmitters, possibly contributing to some symptomatology. A mutation in Mecp2 causes this unique disorder of brain development. Neuronal mosaicism for normal and mutated Mecp2 produces a consistent phenotype in the classic female patient and a small brain with some preserved islands of function, but with an inability to support hand use and speech. This paper summarizes our current observations about neuropathology of Rett syndrome. MRDD Research Reviews 2002;8:72-76. 相似文献

Parkinson's patients (PD) made pro- and antisaccades: In the no-delay condition, the target appeared concurrent with the GO signal. In the delay condition, the target appeared before the signal for movement. Second, we probed spatial working memory in PD. Subjects looked to the remembered locations of sequential targets. In the no-delay prosaccade condition, PD had faster reaction times, made more express saccades, and exhibited hypometria. In the no-delay antisaccade condition, PD had longer reaction times and made more direction errors. In the delay tasks, PD made more direction errors and had more difficulty withholding a movement. PD made more sequencing errors in the spatial working memory task. These findings are consistent with a basal ganglia pathophysiology influencing eye movement processing in the frontal cortex. 相似文献

This study explored the generalizability of the Video Suggestibility Scale for Children (VSSC), which was developed by Scullin and colleagues (Scullin & Ceci, 2001; Scullin & Hembrooke, 1998) as a tool for discriminating among children (aged three to five years) who have different levels of suggestibility. The VSSC consists of two subscales; Yield (a measure of children's willingness to acquiesce to misleading questions) and Shift (a measure of children's tendency to change their responses after feedback from the interviewer). Children's (N = 77) performance on each of the subscales was compared with their performance using several other measures of suggestibility. These measures included children's willingness to assent to a false event as well as the number of false interviewer suggestions and false new details that the children provided when responding to cued-recall questions about an independent true-biased and an independent false (non-experienced) event. An independent samples t-test revealed that those children who assented to the false event generated higher scores on the Yield measure. Hierarchical regression analyses revealed that Yield was a significant predictor of the number of false details reported about the false activity, but not the true-biased activity. There was no significant relationship between the Shift subscale and any of the dependent variables. The potential contribution of the VSSC for forensic researchers and practitioners is discussed. 相似文献

Prayer is more than a bowed head and folded hands. It is the deep longing that is expressed by mute bodies and by our souls, the center of being that connects us to God. Chaplains engage in dialogues that heal, as they risk the encounter with another—soul to soul—discerning the heart of another's concern to find the healing required. 相似文献

Unique pathways to resilience across cultures 总被引:3,自引:0,他引:3

An international mixed methods study of resilience of 14 sites in eleven countries identified seven tensions that youth resolve in culturally specific ways. Resolution of these tensions is foundational to experiences of resilience. This paper reports on the qualitative findings from interviews with 89 youth. Results support a culturally embedded understanding of positive youth development that better accounts for young people's resilience in western and non-western countries. Specifically, the seven tensions identified include: access to material resources, relationships, identity, cohesion, power and control, social justice, and cultural adherence. Findings show that no one pattern in the resolution of these tensions predicts resilience better than another. A case study of a Palestinian boy demonstrates the intersection of the seven tensions and the uniqueness of their resolution. The implications of this work for interventions is discussed. 相似文献

Previous studies have found that in American culture high-arousal positive states (HAP) such as excitement are valued more and low-arousal positive states (LAP) such as calm are valued less than they are in Chinese culture. What specific factors account for these differences? The authors predicted that when people and cultures aimed to influence others (i.e., assert personal needs and change others' behaviors to meet those needs), they would value HAP more and LAP less than when they aimed to adjust to others (i.e., suppress personal needs and change their own behaviors to meet others' needs). They test these predictions in 1 survey and 3 experimental studies. The findings suggest that within and across American and Chinese contexts, differences in ideal affect are due to specific interpersonal goals. 相似文献
