Four different undergraduate psychology courses with no allotted classroom time slots were taught in the same term by means of a computer-based version of Keller's personalized system of instruction (PSI), called computer-aided personalized system of instruction (CAPSI). Students' performance and ratings indicate that CAPSI is a viable on-line educational method. 相似文献

The present study examined generalization along a dimension based on a verbal concept of occupational status. The status dimension was scaled by students who placed occupation names into five status categories, Category 1 representing highest status and Category 5 the lowest status. In two experiments, key presses by students were occasionally reinforced when a slide showing an occupation name from Status Category 3 was present. For half the subjects, key presses were not reinforced during a name from Category 1; for the other half, presses were not reinforced during a name from Category 5. Occupation names from all status categories were later singly presented. In this generalization test, subjects typically divided the dimension into two parts, responding alike to all names within each part. The results suggest that generalization along a dimension in humans is mediated by a subject's verbal classifications of stimuli. 相似文献

Reinforcement of an instrumental response results not from a special kind of response consequence known as a reinforcer, but from a special kind of schedule known as a response-deprivation schedule. Under the requirements of a response-deprivation schedule, the baseline rate of the instrumental response permits less than the baseline rate of the contingent response. Because reinforcement occurs only if the schedule deprives the organism of the contingent response, reinforcement cannot result from any intrinsic property of the contingent response or any property relative to the instrumental response. Two typical effects of response-deprivation schedules—facilitation of the instrumental response and suppression of the contingent response—are discussed in terms of economic concepts and models of instrumental performance. It is suggested that response deprivation makes the contingent response function as an economic good, the instrumental response as currency. 相似文献

Best practice guidelines recommend that eyewitness lineup administrators be blind to a suspect's identity, but no research has investigated whether the mere presence of a lineup administrator impacts eyewitness identification decisions. Informed by social facilitation theory, we predicted that the presence of an audience would differentially impact identification accuracy for same- and other-race identifications. Participants (N = 191) viewed same- and other-race lineups either with an audience or alone. Although the presence of an audience did not directly impact identification accuracy, significant indirect effects indicated that the audience provoked evaluation apprehension which hindered other-race identification accuracy and improved same-race identification accuracy. We suggest that using double-blind lineup procedures may not sufficiently protect eyewitness identification accuracy when making other-race lineup decisions in the presence of others. 相似文献

高创造力群体的界定是创造力研究的重要前提,但迄今极少有研究关注以往研究中高创造力群体间的同质性问题。本研究以创造力问题提出能力测验调查了两所高校(一所地方高校和一所教育部直属高校)的975名大学生的创造力,通过极端组方法(extreme groups approach, EGA)为大学生创造力水平分组,考察不同创造力分组之间的差别。研究发现:地方高校和部属高校的高创造力大学生被试,在创造力的流畅性、变通性和独特性三个维度上,均存在显著差异。本研究结果提示,大学生高创造力组间可能存在质的差别,因此相关研究在外推结果时需要采取谨慎态度;研究者在实验过程中和讨论文献结果的可比性时一定要关注样本的同质性问题。 相似文献

To trace how age and language experience shape the discrimination of native and non-native phonetic contrasts, we compared 4-year-olds learning either English or French or both and simultaneous bilingual adults on their ability to discriminate the English /d-th/ contrast. Findings show that the ability to discriminate the native English contrast improved with age. However, in the absence of experience with this contrast, discrimination of French children and adults remained unchanged during development. Furthermore, although simultaneous bilingual and monolingual English adults were comparable, children exposed to both English and French were poorer at discriminating this contrast when compared to monolingual English-learning 4-year-olds. Thus, language experience facilitates perception of the English /d-th/ contrast and this facilitation occurs later in development when English and French are acquired simultaneously. The difference between bilingual and monolingual acquisition has implications for language organization in children with simultaneous exposure. 相似文献

尽管医学本科生在毕业时都已接受了必要的本科教育,但许多毕业生仍然无法适应这个快速进步变化的社会,在短时间内成为社会需要的医疗人才。我们必须承认,医学本科教育中尚有许多亟待解决的问题。以亲身体验,较全面地分析了中国大陆与港台及国外大学的差异,对医学本科教育改革提出了几点拙见。 相似文献

工科院校大学生自我和谐感与人际交往能力的关系研究 总被引:2,自引:0,他引:2
采用自我和谐量表(SCCS)和自编的大学生人际交往能力量表,研究工科院校大学生自我和谐的状况、人际交往状况以及两者的相关。发现人际交往能力的整体状况对自我和谐状况有一定的预测作用,大学生文理科差异会导致其自我和谐状况出现差异,且不良的人际交往能力会引发自我的不和谐。 相似文献
