Incorporating a cross-cultural curriculum into genetic counseling training programs demonstrates a professional conviction of genetic counselors that cultural issues are important in genetic counseling. Funded by the Special Projects Fund in 1993 from the National Society of Genetic Counselors and the Kitson Fund from the Department of Social, Organizational, and Counseling Psychology, Teachers College, Columbia University, theHandbook of Cross-Cultural Genetic Counseling was developed to provide genetic counseling programs a curriculum to teach cross-cultural genetic counseling. The theoretical rationale for the development of a cultural curriculum is presented. By expanding cultural knowledge, developing an awareness of oneself and others, and increasing the repertoire of culturally relevant counseling skills within a socio-political context, genetic counselors will be able to better serve all clients seeking genetic counseling. 相似文献

Contrast sensitivity was measured for 12 healthy young males while sober, after ingestion of an alcohol placebo, and after ingestion of alcohol (95% grain alcohol; mean estimated blood alcohol level = .088%). Observations were made for both stationary gratings and gratings that traveled through a circular path and required pursuit eye movements. The significant alcohol-related reduction in contrast sensitivity was 2.6 times greater for moving (.29-log-unit reduction) than for stationary gratings (.11-log-unit reduction). The loss in contrast sensitivity for the moving gratings of high spatial frequency (12 cpd) was particularly severe (.37 log unit). Estimated blood alcohol level was correlated with the loss in contrast sensitivity for moving gratings (r = .61), but not with the loss for stationary gratings. Estimated blood alcohol level was strongly correlated with the difference between the loss in contrast sensitivity to moving and stationary gratings (r = .75). These results are consistent with reports that alcohol consumption degrades the ability to make pursuit eye movements. Subjects’ perceived intoxication level was not a reliable predictor of any index of visual performance. 相似文献

本工作采用食物性运动,条件反射方法和慢性微电极记录技术。条件反射实验在9只兔上进行,海马自发放电的实验在22只兔上进行。在9次实验中,30μg的东莨菪碱注入一侧脑室后,条件反射均受到抑制,而吃食则不受影响。注射剂量为45μg时,注射后3—5分,条件反射完全消失,而吃食行为在了次实验中不受影响,在2次实验中稍有减弱,注射后20分钟左右条件反射开始恢复;侧脑室注射40μg的东莨菪碱后,海马神经元的自发活动无明显改变。文中并对抗胆碱药作用于海马抑制条件反射的可能方式进行了讨论。 相似文献

在主动触觉中,长度知觉通过手的各种触摸动作而实现,构成各种触觉长度知觉方式。例如,可以用食指沿物体表面从一端摸到另一端,或用拇指和食指夹住物体两侧并触摸。这两种触觉长度知觉方式在感知长度时是不一致的(Hohmuth)。我们已经报 相似文献

几种色光呈现条件下人眼红、绿光感受性的变化 总被引:1,自引:0,他引:1
采用阈值法探讨了人眼在红、橙、绿、蓝4种色光适应条件下红、绿光感受性的变化及机制。结果表明:当背景及目标均为稳光时,在不同的背景光条件下,人眼554nm(绿)及656nm(红)光感受性的变化显示了明显的感觉颉抗性效应,且不受色觉适应的影响;如果所呈现的背景光是稳态光,目标先是闪烁光,除辨别是现在554nm背景光上的656nm(红)目标,在其余条件下,均未发现颜色感觉颉抗效应;如果背景光是闪烁光,目标光为稳态光时,在不同的背景光条件下,人眼对554nm(绿)及656nm(红)波长的辨别结果有感觉颉抗效应存在,并且辨别感受性也明显提高。 相似文献

本实验的目的是探索加工层次(方式)对自由回忆和再认的影响,实验条件同时包含适合于原来加工方式的提取内容以及不适合于原来加工方式的提取内容。结果表明,深层的意义水平的加工方式产生了最好的保持。从提取内容与加工方式的一致性对结果进行了讨论,最后强调了加工方式对提取是极端重要的。 相似文献

A series of stimuli, words and faces, were presented tachistoscopically to 24 dextrals and 12 sinistrals. The stimuli were presented to one eye at a time and the subjects were instructed to respond to specific words or stimuli with a specific hand. The results indicate that (1) cerebral functional asymmetry is related to handedness; in the dextrals, the left hemisphere is more specialized in verbal recognition, while in the sinistrals, the right hemisphere is more specialized in recognizing non-verbal material. (2) An ipsilateral hand-and-eye combination is a valid method of measuring intrahemispheric information processing, provided that the tachistoscopically presented visual stimuli are capable of inciting specialized hemispheric function. The dominant relationship among the crossed and non-crossed visual pathways is discussed. 相似文献

In Experiment 1, pictures were presented to subjects two, five, or eight times, and subjects were asked to imagine each pciture two, five, or eight times. Subsequently, subjects estimated the number of times each picture had been presented. Their estimates of the frequency of these external events were influenced by imagination trials; this effect was greater for good imagers than for poor imagers. Experiment 2 involved a similar design in which subjects were asked either to imagine the same referent for a word or to imagine a different referent for a word on successive imagination trials. Consistency (same referent) did not increase the influence of imaginations on immediate judgments of external frequency. Thus, the results of Experiment 1 were attributed to the greater accuracy (as opposed to greater consistency) of good imagers' internal generations of the stimuli. Furthermore, variation (imagining different referents), like greater accuracy, increased the effects of imagination trials on immediate but not on delayed judgments of frequency. Possible mechanisms underlying these effects are discussed. In general, the two studies show that qualitative characteristics of completely covert generations influence their impact on estimates of the frequency of external events. 相似文献
