Since the 1970s, the Heuristics and Biases Program in Cognitive Psychology has shown that people do not reason correctly about conditional probability problems. In the 1990s, however, evolutionary psychologists discovered that if the same problems are presented in a different way, people's performance greatly improves. Two explanations have been offered to account for this facilitation effect: the natural frequency hypothesis and the nested-set hypothesis. The empirical evidence on this debate is mixed. We review the literature pointing out some methodological issues that we take into account in our own present experiments. We interpret our results as suggesting that when the mentioned methodological problems are tackled, the evidence seems to favour the natural frequency hypothesis and to go against the nested-set hypothesis. 相似文献

The Wentzel–Kramers–Brillouin method is employed to study the cut-off frequencies of the horizontal shear waves in a freestanding functionally graded piezoelectric–piezomagnetic material film with the electrically and magnetically open boundary conditions. An analytical solution, which could be used in analyzing the problems of various functionally graded materials, is proven to have high precision by analytical analysis and a numerical example. The results reveal that the set of cut-off frequencies is a series of approximate arithmetic progressions. A theoretical foundation based on the relationship between the cut-off frequencies and the materials’ gradient property is established for nondestructive evaluation. 相似文献

汉字双向启动效应的实验研究 总被引:1,自引:0,他引:1
以五类高、中、低频汉字为材料.用词汇决定任务与诵读回忆任务间的相互启动方法,对汉字启动效应进行了初步探讨。结果发现,形与音都具有启动作用;低频字表现出受到或产生更大的抑制性启动作用;对于真伪识别任务,则诵读回忆任务中与其字形相似的字产生的启动效果更大;对于诵读回忆任务,则真伪识别任务中与其字音相似的字产生的启动效果更大.结果表明,字形与字音启动作用的大小取决于目标字加工中二者相对作用的大小。 相似文献

The dopaminergic system is implicated in depressive disorders and research has also shown that dopamine constricts lexical/semantic networks by reducing spreading activation. Hence, depression, which is linked to reductions of dopamine, may be associated with increased spreading activation. However, research has generally found no effects of depression on spreading activation, using semantic priming paradigms. We used a different paradigm to investigate the relationship between depression and spreading activation, one based on word frequencies. Our sample included 97 undergraduates who completed the BDI-II and the Controlled Oral Word Association test as well as the Animal Naming test. The results indicated that the group scoring within the depressed ranged evidenced greater spreading activation as compared to those who scored within the normal range on the BDI-II. The implications of these results as they relate to creativity in depression is discussed. 相似文献

Previous research on feedback frequency suggests that more frequent feedback improves learning and task performance (Salmoni, Schmidt, & Walter, 1984). Drawing from resource allocation theory (Kanfer & Ackerman, 1989), we challenge the “more is better” assumption and propose that frequent feedback can overwhelm an individual’s cognitive resource capacity, thus reducing task effort and producing an inverted-U relationship with learning and performance over time. We then propose that positive and negative affective states will moderate the inverted-U relationship between feedback frequency and task performance. We test these propositions in an experimental study where the frequency of task feedback is manipulated. Results show that feedback frequency exhibits an inverted-U relationship with task performance, and this relationship is mediated by task effort. This curvilinear relationship is then moderated by individual’s positive affective state. 相似文献

为了解国外军事心理学研究的动态和研究领域,本文对1980年至2009年国际军事测量学会(IMTA)发表的论文进行了系统分析。结果显示,军人心理选拔等七个领域的文献数量占总数的85.7%;在近30年的文献中,关键词训练与教育、工作绩效、选拔、工作分析等出现频率最高,超过文献总数的58.0%;在近10年的文献中,关键词选拔、领导力、工作分析、工作绩效、离职和人因素等前8项出现频率最高,合计达70.2%。军人心理选拔、军事领导和组织行为、军事临床心理等方面越来越受到军事心理学研究者的重视。 相似文献
