A controlled group study of pedestrian-skill training for the mentally retarded

Pedestrian-skills training procedures were compared using 30 mentally retarded institutionalized adults. Ten subjects were randomly assigned to a no-treatment control group and ten subjects were assigned to each of two modes of pedestrian-skills training. The training methods included a form of individualized classroom training consisting of the practice of correct behavior using movable figures on a scale model of an intersection, vs independence training which emphasized self-evaluation of performance, social reinforcement, sign recognition and the utilization of a mock-up of an intersection on the hospital grounds. Data were taken on sign recognition, verbal and performance based responses to classroom training of pedestrian skills, performance of skills at an intersection on the hospital grounds, and performance of pedestrian skills in the community. Independence training proved to be significantly more effective than no treatment or classroom training. In addition, classroom training proved to be significantly more effective than no treatment at all.     

个体特征因素对师徒之间选择倾向的影响

师徒的相互选择过程是师徒关系研究中的一个重要问题。本文采用三个实验探讨了影响师徒相互选择倾向的个体特征因素。实验一和实验二探讨了徒弟选师傅时,师傅的外向性、成就动机水平、管理职务和性别一致性对徒弟选择师傅倾向的影响。实验三探讨了师傅选择徒弟时,徒弟的外向性、成就动机水平和性别一致性对师傅选择徒弟倾向的影响。实验结果表明在徒弟选择师傅时,师傅的外向性、成就动机、管理职务,是影响因素;在师傅选择徒弟时,徒弟的外向性、成就动机水平是影响因素。     

Déjà vu现象理论及其相关实验研究述评

Déjà vu指任何对目前体验的一种不适宜的熟悉感,并伴随着对过去体验的不确定感。对déjà vu的进一步深入研究将澄清对记忆的认识。首先,文章阐述了déjà vu现象产生的理论解释;其次,将相关的实验研究概括为：阈下知觉实验研究和阈上知觉实验研究。最后,讨论了目前déjà vu研究中所存在的一些问题。
