Priming of pop-out (PoP) refers to the facilitation of performance that occurs when a target-defining feature is repeated across consecutive trials in a pop-out oddball search task. The underlying mechanism of PoP has been poorly understood and raises important questions about how our visual system is guided by past experiences, even during bottom-up processing. Lee, Mozer, and Vecera (Attention, Perception, & Psychophysics, 71, 1059–1071, 2009) demonstrated that PoP remained unaffected by a concurrent non-spatial visual working memory (VWM) load, and they concluded that PoP occurs through feature gain modulation, essentially eliminating the contribution of memory representations in VWM to PoP. In the present study, we followed up on those results by (a) replicating the null effect of non-spatial VWM load on PoP and (b) examining the effect of spatial VWM load on PoP. The results showed that spatial VWM load does interfere with PoP, supporting the notion that spatial VWM is involved in PoP. In Experiment 2, we extended this finding by manipulating VWM load and observing its consequence on the magnitude of PoP. Increasing spatial VWM load decreased the amount of PoP observed, in a dose-dependent manner, whereas changes in non-spatial VWM load did not. Contrary to Lee et al.’s conclusions, these results suggest that VWM resources appear to contribute to the occurrence of PoP, supporting the theory that PoP is, in fact, a multilevel process in which the deployment of spatial attention, relying on VWM representations, plays an important role. 相似文献

Although men typically hold favorable views of advertisements featuring female sexuality, from a Terror Management Theory perspective, this should be less the case when thoughts of human mortality are salient. Two experiments conducted in South Korea supported this hypothesis across a variety of products (e.g., perfume and vodka). Men became more negative towards advertisements featuring female sexuality, and had reduced purchase intentions for those products, after thinking about their own mortality. Study 2 found that these effects were mediated by heightened disgust. Mortality thoughts did not impact women in either study. These findings uniquely demonstrate that thoughts of death interact with female sex-appeal to influence men’s consumer choices, and that disgust mediates these processes. Implications for the role of emotion, and cultural differences, in terror management, for attitudes toward female sexuality, and for marketing strategies are discussed. 相似文献

Prosocial behaviour is an interdisciplinary topic, involving psychologists, philosophers, and educators. Based on experimental helping research, some moral philosophers have claimed that helping behaviour is entirely situationally determined. The dominance of situational factor experimentation gives the appearance that situational factors alone can explain helping behaviour. This meta-analysis investigated situational explanations of helping behaviour with 286 effects and 46,705 participants from experimental studies with non-manipulation control groups, and observed unilateral adult behavioural helping. Results indicated expected group differences in helping behaviour frequency among help encouraging or help discouraging experimental conditions and no-manipulation control conditions. Helping behaviour was also frequent in help discouraging and control conditions and far from universal in help encouraging conditions. Because helping occurred in control groups, situational factors cannot explain all observed helping. Because helping was not universal in help encouraging conditions, it raises the question of individual differences in responsiveness to helping cues. 相似文献

教学警示病例在骨科教学中的应用与思考 总被引:6,自引:0,他引:6
骨科教学警示病例主要就是指用于教学,并和骨科基本知识理论及伦理有关的误诊误治病例,按照骨科内容相关的原则进行分类.在骨科教学中适当的插入一些警示病例可以起到加深印象、辅助记忆,提高责任意识,强化人性医学的作用.同时我们注意控制警示教育病例的数量;合理穿插、安排教学警示病例,并配合其它教学方法教学,课堂气氛活跃,效果良好,随访结果满意. 相似文献

Understanding the feasibility of using KEYS to assess the organizational climate for creativity in non‐Western societies is essential for researchers studying cultural influences on workers' perceptions of workplace climates. This study reports on the effectiveness of translating KEYS, using data from 401 employees of 13 different companies in Taiwan. A confirmatory factor analysis was performed and its results indicated a satisfactory fit for a 10‐factor model. However, six items tackling environmental obstacles had low factor loadings (<0.3) and should either be eliminated or amended. The results raise questions regarding the role of cultural influences in international studies that assess creativity climates. Further research into the conceptualization of organizational creativity in Chinese societies is warranted. 相似文献

研究生在撰写医学论文时普遍存在统计学误用和滥用问题,几乎在统计学应用的各个环节上都有不妥甚至错误之处.为保证期刊质量,医学期刊编辑在处理稿件时,将会从论文中"材料和方法"、"结果"、"结论"几部分分别审查稿件中的统计学问题,一旦发现统计学错误,稿件就会被退回.因此,为避免因为统计学问题被拒稿,研究生应在论文撰写时正确运用统计学方法,对稿件退修中的统计学方法修改意见要引起足够的重视. 相似文献

胸腔闭式引流术是一项有创性操作,多种因素可能会引起胸膜腔及肺内感染.为了预防及处理胸腔闭式引流术后的相关性感染,我们从临床角度讨论更换胸腔闭式引流瓶的间隔时间、胸腔闭式引流管口的消毒、胸腔引流液逆流的预防、胸腔引流管的更换以及由于留置胸腔闭式引流引起的肺内感染的处理等问题,为临床医护人员对该项操作提供参考和对策. 相似文献
