本文用主成分分析法对韦氏成人智力量表中国修订本(WAIS-RC)的城市与农村两个常模以及WAIS和WAIS-R进行因素分析,发现这三套测验都负荷较高的g因子;常识,领悟,相似性和词汇测验负荷较高的A(言语理解)因子,填图,木块图,图片排列和物体拼凑测验负荷较高的B(知觉组织)因子,而数字广度,算术和数字符号测验负荷较高的C(记忆/集中注意)因子。因子模型是极相似的,这说明WAIS-RC具有较好的结构效度,保持了原量表的功能。同时,所建立的因子模型也为使用者在使用测验和分析解释结果时提供了有用的参考资料。  相似文献

采用生理心理学的实验方法.对强噪音下四组不同处理背景大鼠的旷场反应、援食、饮水、排泄和尿生物化学等方面进行比较。结果发现:①Ⅰ组(强刺激组)的各类指标均发生情绪性(恐惧)改变。与2组(预防训练Ⅰ组)、3组(预防训练Ⅱ组)、4组(控制组)以及自身基线(MAO)比较差异显著;②适应性训练有助于防止大鼠恐惧发生及上述各类指标发生异常.③由于训练的方法不同,预防的效果也不同。3组与4组比较无显著差异,2组与4组比较某些指标有显著差异。④1组和2组部分大鼠出现皮肤、消化道病变。  相似文献

In the present paper, we describe a method for recording the coordinates of a fish in an aquarium in a three-dimensional space, using a single video camera and a mirror. We use photogrammetic equations for this, considering the image obtained in the mirror as a virtual image obtained by a second camera. A transformation of the coordinate system is required to express the obtained coordinates in anx,y,z system defined by the edges of the aquarium. The accuracy of the proposed method was estimated, and errors in extreme conditions were found to be 0.8% to 1.2 %, compared with the dimensions of the aquarium used in the test.  相似文献

Two experiments tested whether a dogmatic alcohol prevention message may, by arousing psychological reactance (the motivation to reassert a threatened freedom) result in more subsequent alcohol consumption, compared to a neutral message. In Study 1, 535 college students received either a high-threat (dogmatic) or low-threat (neutral) message recommending either abstinence or controlled drinking. Results indicated that high-threat messages were rated more negatively and resulted in more drinking intentions compared to low threat. The negative effect of high threat on message ratings was most pronounced for habitually heavy drinkers and an abstinence-espousing message. In Study 2, under the guise of a “memory study,” 74 college students received either a high- or low-threat message recommending abstinence from alcohol. Then, under the guise of a “perception study,” all subjects participated in a taste-rating task in which their beer consumption was unobtrusively measured. Results indicated that the effect of high threat was most negative for male heavy drinkers, who drank significantly more beer compared to low-threat controls. These results suggest that the persuasive ability of alcohol prevention efforts depend to a considerable extent on the reactance-arousing properties of the materials and that dogmatic alcohol prevention materials may have counterproductive effects for some college students.  相似文献

情绪活动和某些生理机能或心理过程的关系很久以来就已进行过大量的研究。外科手术前患者的情绪状态及其相应的生理机能的变化,也曾受到注意。患者在意识清醒状态下进行针麻手术,他的情绪状态对针麻过程及其效果的作用如何,这种情绪状态和某些心理、生理机能有什么联系?这是针麻临床上和理论上应予探讨的问题之一。本工作试图综合分析患者的情绪状态和与之伴随的某些生理生化指标变化,以探讨  相似文献

Theories relating to self-efficacy have developed rapidly since Bandura first proposed the concept in 1977. In the past two decades, psychologists have carried out numerous studies to research the cultural and psychological changes in social development. The research topic of this study is whether self-efficacy changes over time. This study uses a meta–meta analysis and includes 13 meta-analyses, including 536 effect sizes, with a total sample size of 421,880. We find that individual self-efficacy increases over time, which may be related to social development trends. However, the effects of interventions on self-efficacy remain similar (Qmodel = 1.807, df = 1, p > .05), and a possible explanation is that time effects of self-efficacy confuse the effects of intervention, because both in the intervention group and control group, the average of self-efficacy increases over time. And we find that a general decline in the predictive effects of self-efficacy (Qmodel = 5.117, df = 1, p = .024), especially the ability to predict relatively objective variables (e.g. job performance, teaching effectiveness, and transfer of training). A possible explanation is that as social development people tend to overestimate their self-efficacy. Another possible explanation is that the effect sizes in the original studies being overrated, may due to intentional selective reporting or unintentional statistical errors.  相似文献

隐藏情绪识别对公共安全防范与预警具有重要的意义。微表情是揭示隐藏情绪的一条重要通道。但目前隐藏情绪研究较少且微表情因其细微幅度与快速出现等特性难以识别, 其研究尚未在实际中广泛应用。因为, 隐藏情绪的认知与表达机理亟需系统的研究,采集实际场景中的微表情数据, 并以脑电信号辅助微表情的精确标注是提高微表情标注效率的有效途径。深入研究微表情识别方法, 并辅以人脸颜色、注视估计和非接触生理信号等多通道数据, 以检测与识别隐藏情绪。社会公共安全是隐藏情绪分析和识别的典型场景。面向精神疾病患者两害行为(即危害自身或他人的危险行为)风险评估和服刑人员会见场景隐藏情绪检测, 可以有效地对相应系统和方法进行验证和修正。  相似文献

Middle school students in Lushan county (N = 315) were assessed 6 months after the Yaan earthquake using a trauma severity questionnaire, a posttraumatic fear questionnaire, a social support questionnaire and a posttraumatic growth inventory to examine the effects of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth (PTG). The results showed that posttraumatic fear mediated the relationship between trauma severity and PTG, and social support moderated the relationship between posttraumatic fear and PTG. These findings suggested that trauma severity could be positively associated with PTG in a direct way or in an indirect way through posttraumatic fear. Moreover, posttraumatic fear had a positive relation to PTG under the condition of high social support level, whereas the relation was non‐significant when the level of social support was low. These results were discussed in terms of their implications for adolescents after trauma.  相似文献
