An expressionless face is often perceived as rude whereas a smiling face is considered as hospitable. Repetitive exposure to such perceptions may have developed stereotype of categorizing an expressionless face as expressing negative emotion. To test this idea, we displayed a search array where the target was an expressionless face and the distractors were either smiling or frowning faces. We manipulated set size. Search reaction times were delayed with frowning distractors. Delays became more evident as the set size increased. We also devised a short-term comparison task where participants compared two sequential sets of expressionless, smiling, and frowning faces. Detection of an expression change across the sets was highly inaccurate when the change was made between frowning and expressionless face. These results indicate that subjects were confused with expressed emotions on frowning and expressionless faces, suggesting that it is difficult to distinguish expressionless face from frowning faces. 相似文献

Instructional applications (apps) are educational software programs that can be accessed via mobile technologies (e.g., iPad, smartphone) and used to help students acquire various academic skills, including mathematics. Although research suggests that app-based instruction (AI) can be effective, there is a paucity of research comparing AI, to teacher-directed instruction (TDI) or to a combination of instructional approaches (CI) involving both AI and TDI in tandem. In an alternating treatments design, we compared AI, TDI, and CI conditions during instruction targeting multiplication facts with six students with learning disabilities. Results were inconsistent across students, and no condition emerged as consistently better than the others. Students completed social validity rating scales, and all approaches were favored by at least one student. Our results support findings from previous research involving similar comparisons between these instructional formats in which no (or minimal) differences across conditions were detected. We conclude that there may not be a meaningful difference between the outcomes achieved using AI, TDI, or CI for many students. Results are discussed in terms of directions for the future research. 相似文献

Visual perceptual learning (VPL) can occur as a result of a repetitive stimulus-reward pairing in the absence of any task. This suggests that rules that guide Conditioning, such as stimulus-reward contingency (e.g., that stimulus predicts the likelihood of reward), may also guide the formation of VPL. To address this question, we trained subjects with an operant conditioning task in which there were contingencies between the response to one of three orientations and the presence of reward. Results showed that VPL only occurred for positive contingencies, but not for neutral or negative contingencies. These results suggest that the formation of VPL is influenced by similar rules that guide the process of Conditioning. 相似文献

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi (self-cultivation) is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing (cultivation of the mind and internal piety) and the competence consists of both Ipzhi (setting a solid self-vision/establishing goal) and Silsim (practical mind, grasp changes in reality with a sound mind) in Korean traditional leadership that contributes to expanding the theoretical understanding of ethical leadership. Implications for future research in the area of ethical leadership are discussed. 相似文献

Improving people's motivation to seek meaningful intergroup contact is considered key to facilitating intergroup harmony. Based on moral foundations theory, this study examines how moral foundations as individual traits predict contact willingness with three minority groups (foreign domestic helpers, LGBT, and Chinese expats) and how moral emotions mediate such associations. We tested our hypotheses based on survey data across Hong Kong and Singapore. We found that care/harm foundation positively predicted contact willingness with foreign domestic helpers and LGBT people, mediated by compassion. Sanctity/degradation foundation negatively predicted contact willingness with LGBT people only in Singapore. Loyalty/betrayal foundation served as a positive predictor of willingness to contact Chinese expats. We also found care/harm foundation to be exclusively associated with compassion and promoted willingness to contact with helpers and LGBT people. Our findings highlight the influence of moral foundations, and possibly norms and intergroup dynamics at the societal level in predicting willingness to contact outgroups. 相似文献

To enhance the accuracy and completeness of children's testimony, recommendations have included implementing a practice narrative, during which children are prepared for their role as informative witnesses before discussing the allegations. In the present study, we aimed to systematically examine interviewer behaviour and the informativeness of children's testimony in a field setting. As predicted, interviewers posed fewer prompts, proportionally more open-ended prompts, and children provided proportionally more details in response to open-ended prompts in the substantive phase when preceded by a practice narrative than when no practice narrative was conducted. The relationship was enhanced when the practice narratives were conducted as recommended vs those that were conducted in a less open-ended manner. Together with experimental studies showing clear benefits of practice narratives on children's reports, these results underscore the value of a simple practice narrative as a means of enhancing the reliability of children's testimony. 相似文献

Dynamic occlusion (i.e., accretion and deletion of optical texture at the occluding edge) can occur under many different environmental conditions, for example, objects hidden behind other objects when viewed by a moving observer, objects moving in front of other objects, or an observer approaching a brink. Because each of these conditions may require the actor to respond differently, the actor may need to be able to differentiate these situations reliably. This study was directed at the optical pattern induced by dynamic occlusion that occurs when one locomotes over a rolling terrain (i.e., a corrugated surface). Two experiments were conducted for this purpose. Participants viewed displays simulating their translation along a corrugated surface in which surface corrugation, texture type, and texture density varied as part of experimental control. Results demonstrated that the visual system reliably extracts the global flow pattern for accurate perception of heading direction despite the presence of optical disturbances in optical flow. However, performance nearly failed in the unstructured texture displays wherein optical disturbances were less salient. Still, the results provide strong evidence that human observers are sufficiently sensitive to dynamic occlusion to extract information about heading direction. 相似文献
