The Adams-Creamer hypothesis states that S uses the decay of proprioceptive feedback from an early portion of a movement to cue a timed response at some later time. This hypothesis was tested by creating passive left-arm movement in one group and withholding it from another, and having Ss make a right-hand response when exactly 2.0 sec. had elapsed since the end of the movement Ss with left-arm feedback had less absolute and algebraic error, and greater within-S consistency than did the no-movement control Ss and, when KR was withdrawn, Ss with left-arm movement regressed less than did Ss without the left-arm movement, which provided 2 lines of support for the decay hypothesis. 相似文献

Many indicators suggest that modern society is presently in a period of transition. The older order is showing obvious signs of decline, and elements of a new order appear to be forming. Growing numbers of people are coming to recognize that the worsening global dilemmas are best viewed as symptoms of an underlying disorder involving some of the most deeply underlying assumptions of modern society. The ultimate resolution of these dilemmas will come about, not through politically implemented “solutions,” but through our further evolution to a fundamentally different, “trans‐modern” society. The key challenge to individuals and organizations is to understand the necessary evolutionary change well enough to contribute toward its taking place with a minimum of attendant social disruption and human misery. 相似文献

Aftereffects of adaptation have revealed both independent and interactive coding of facial signals including identity and expression or gender and age. By contrast, interactive processing of non-linguistic features in voices has rarely been investigated. Here we studied bidirectional cross-categorical aftereffects of adaptation to vocal age and gender. Prolonged exposure to young (~ 20 yrs) or old (~ 70 yrs) male or female voices biased perception of subsequent test voices away from the adapting age (Exp. 1) and the adapting gender (Exp. 2). Relative to gender-congruent adaptor-test pairings, vocal age aftereffects (VAAEs) were reduced but remained significant when voice gender changed between adaptation and test. This suggests that the VAAE relies on both gender-specific and gender-independent age representations for male and female voices. By contrast, voice gender aftereffects (VGAEs) were not modulated by age-congruency of adaptor and test voices (Exp. 2). Instead, young voice adaptors generally induced larger VGAEs than old voice adaptors. This suggests that young voices are particularly efficient gender adaptors, likely reflecting more pronounced sexual dimorphism in these voices. In sum, our findings demonstrate how high-level processing of vocal age and gender is partially intertwined. 相似文献

Occupational stress adversely affects productivity, absenteeism, and job turnover, and contributes to health-related problems. The effects of organizational level and gender on the specific sources of occupational stress assessed by the Job Stress Survey (JSS) were evaluated for a heterogeneous sample of 1,791 working adults (860 males, 931 females) employed in 2 industrial companies and a large state university. Significant main or interactive effects of organizational level and/or gender were found for the JSS Item Index, Severity and/or Frequency scores of 29 of the 30 JSS items. Organizational level effects were both more numerous and larger in magnitude than gender effects. Employees at higher organizational levels reported that they experienced stress more often while making critical decisions and dealing with crisis situations than did workers at lower levels, for whom inadequate salary and lack of opportunity for advancement were more stressful. For males, work stress was more strongly related to concerns about their role in the power structure of an organization, whereas female employees reported experiencing more severe stress when there was a conflict between job requirements and family relationships. 相似文献

We investigated the readability of seven mental health brochures on mental, emotional, and behavioral disorders in children that were selected from a website developed by the Center for Mental Health Services at http://www.mentalhealth.org. The reading grade levels of the brochures ranged from 11.1 to 14.8 (mean 13.23), considerably higher than the 8th grade level recommended for educational material by the U. S. Department of Education (1986). On other readability variables, assessed using the Readability Assessment Instrument (RAIN; Singh, 1994), all brochures met criterion on most variables but failed on those for new words (audience appropriateness) and print size. This is a favorable result in comparison with other studies that have assessed readability of mental health information on the Internet using the RAIN, although less so with reading grade levels. 相似文献

通过对日本731部队进行细菌战及美国掩盖这一事实的案例分析,强调科学不能背离人道,而要为人道服务;政治也不能不顾人道,反人道的政治终究是要失败的。因此,尊重伦理的基本价值、基本原则和基本规范具有极大的重要性和现实性。 相似文献

采用学习 -再认的方法对自由复述、部分特征的言语命名复述和视觉表象复述三种实验条件下图形的记忆效果进行了研究。结果表明 ,(1)图形记忆中存在明显的难度效应 ,难以命名图形的再认正确率高于易命名图形 ,反应时低于易命名图形。 (2 )被试在复述图形时 ,更倾向于选择那些难以命名的特征作为复述对象 ,以便把整个图形都记住。 (3)易命名图形的言语命名复述成绩好于视觉表象复述 ;而难以命名图形则不存在这种差异。两者自由选择时 ,将加快记忆提取的速度 相似文献

自我意识情绪是个体在具有一定自我评价的基础上,通过自我反思而产生的情绪。自我意识情绪与基本情绪既有区别又有联系。自我表征、自我觉察、自我评价过程的卷入是自我意识情绪产生的重要条件。对个体行为进行自我调节、服务于人际交流、人际互惠和个体心理内部需要是自我意识情绪具有的主要功能。自我意识情绪是随着认知的发展而逐渐形成和发展的,并会受到文化的影响。自我报告、非言语行为编码技术、言语报告和行为编码、神经成像技术是自我意识情绪的主要研究方法。自我意识情绪的普遍性和特殊性需要进一步跨文化研究的验证 相似文献
