Four studies were conducted to investigate cultural differences in predicting and understanding regression toward the mean. We demonstrated, with tasks in such domains as athletic competition, health and weather, that Chinese are more likely than Canadians to make predictions that are consistent with regression toward the mean. In addition, Chinese are more likely than Canadians to choose a regression‐consistent explanation to account for regression toward the mean. The findings are consistent with cultural differences in lay theories about how people, objects and events develop over time.  相似文献

将短时记忆再认与长时记忆范畴判断两类不同性质的信息提取任务相并列,探讨了双任务条件下的信息提取过程是如何进行的。实验结果表明,双任务并存时,no反应的总平均反应时不等于两种任务单独进行时各自no反应的平均反应时之和(减去一次视觉动作反应时后),而是与其中一个较后完成的过程的no反应平均反应时相近。因此推断双任务并存时,信息提取过程不是完成一个再进行另一个的系列加工过程,而是二者同时平行加工的过程。  相似文献

This study investigated how consistency between categories and attributes determines attribute selection in hierarchical category learning. Participants learned six categories for which number and color were equally relevant attributes, followed by a transfer task, to test which attribute was used. Before that, half of them learned embedding higher-level categories for which numbers were likely to be used. Orthogonal to this factor, the hierarchical structure was made explicit for half of them by category labels. The results showed that participants used numbers in the prior learning, but that the use of numbers was inhibited in the subsequent six-category learning task. However, this inhibitory effect was reduced when the hierarchical structure was explicit. The pattern of results suggests that attribute selection is determined by structural consistency between categories and attributes, not by a prior use of an attribute.  相似文献

Introduction

Past research has highlighted the relevance of cognitive appraisals in the link events-emotions (e.g., appraisal of an event's importance and its pleasant or unpleasant valence). We hypothesized a 3-way interaction between affective events (hassles and uplifts), cognitive appraisals of importance and intrinsic pleasantness on emotional activation.

Objective

In this study, we investigated predictors of emotional activation at workplace.

Method

We collected qualitative and quantitative data from 87 employees on work-related daily events (n = 571), cognitive appraisals and emotional reactions.

Results

Results showed that the cognitive appraisal of an event's importance moderated the relationship between uplifts and emotional activation: the positive relationship was stronger when uplifts were appraised as highly important. However, the intrinsic pleasantness did not moderate this relationship. Results supported the 3-way interaction hypothesized for daily hassles.

Conclusion

The findings suggest that appraisals of an event's importance and intrinsic (un)pleasantness influence the link between daily events and emotional activation differently for hassles and uplifts. We discuss the implications of these findings for research and practice.  相似文献

Feature–reward association elicits value-driven attentional capture (VDAC) regardless of the task relevance of associated features. What are the necessary conditions for feature–reward associations in VDAC? Recent studies claim that VDAC is based on Pavlovian conditioning. In this study, we manipulated the temporal relationships among feature, response, and reward in reward learning to elucidate the necessary components of VDAC. We presented reward-associated features in a variety of locations in a flanker task to form a color–reward association (training phase) and then tested VDAC in a subsequent visual search task (test phase). In Experiment 1, we showed reward-associated features in a task display requiring response selection and observed VDAC, consistent with most previous studies. In Experiment 2, features presented at a fixation display before a task display also induced VDAC. Moreover, in Experiment 3, we reduced the time interval between features and rewards so that features appeared after a task display and we obtained marginally significant VDAC. However, no VDAC was observed when features and rewards were simultaneously presented in a feedback display in Experiments 4 and 5, suggesting that a direct association between feature and reward is not sufficient for VDAC. These results are in favor of the idea that response selection does not mediate feature–reward association in VDAC. Moreover, the evidence suggests that the time interval of feature and reward is flexible with some restriction in the learning of feature–reward association. The present study supports the hypothesis that theories of Pavlovian conditioning can account for feature–reward association in VDAC.  相似文献

未来情景思维(Episodic Future Thinking, EFT)主要指人们基于当前情景或过去经历来思考、想象未来的过程, 是人们对于未来的一种设想。根据已有的行为实验和神经影像学等多个方面的研究结果, 系统论述了未来情景思维的概念和特征, 以及个体过去的生活经历及相应记忆和个体生活目标对其的影响, 通过概括和分析行为和脑神经两方面的证据来论述未来情景思维会对人们具体生活实践产生积极与消极的双向影响。当然, 未来还需要进一步加强未来情景思维研究的广度和深度, 特别是要细化未来情景思维的类型, 探讨未来情景思维可能导致的不适应行为以及影响个体心理和行为的作用机制, 从而为人们如何更积极地适应未来提供更充分的实证证据和理论构想。  相似文献

Understanding the meaning of an emergency exit sign is essential for escaping from a building during a disaster. According to International Organization for Standardization 7010:2011, there are leftward and rightward running‐man exit signs indicating the location of an exit door. However, there is neither an application rule regarding which direction the sign should point nor a rule for where it should be attached in the horizontal dimension. We examined the effect of the heading direction of the running man and its horizontal locations on the selection of exit directions. A modified spatial Stroop task as an unforced‐choice task was designed by combining the running man's heading direction and its horizontal location. The results showed both facilitation and inhibition effects, conflict adaptation, and post‐error slowing reflecting top‐down control. These findings suggest that the heading direction of the running‐man exit sign includes evident directionality. This should be considered in designing and establishing standardized emergency exit signs. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

A qualitative study was conducted with 48 Chinese counselors and psychotherapists who were interviewed in 2006 and an independent sample of 50 participants who responded to a survey in 2014. This study aims to explore how the new emerging expansion of mental health practice is related to issues and challenges of dual role relationship and how the well-engrained values and social characteristics of Chinese culture influences perceptions and resolution of ethical dilemmas. The participants identified similar dual relationships in 2006 and 2014: (a) Incidental boundary crossings, a sexual or romantic relationship, a dual social relationship, and a professional dual relationship were the most frequently reported types of dual relationships encountered by Chinese practitioners, and (b) the socioeconomic and cultural context and the development trajectory of counseling and psychotherapy in China play a significant role in shaping practitioners’ behaviors. The comparison of the data in 2006 and 2014 indicated that practitioners in psychotherapy and counseling have an improved awareness and understanding of ethical issues, evidenced by the decreasing cases of romantic and sexual relationships and increasing cases of social dual relationships influenced by the interrelatedness of traditional Chinese culture.  相似文献
