Many models of decision making neglect emotional states that could affect individuals' cognitive processes. The present work explores the effect of emotional stress on people's cognitive processes when making probabilistic inferences. Two contrasting hypotheses are tested against one another: the uncertainty‐reduction and attention‐narrowing hypotheses of how emotional stress affects decision making. In the experimental study, emotional stress was induced through the use of highly aversive pictures immediately before each decision. Emotional state was assessed by both subjective (state anxiety, arousal, and pleasantness ratings) and objective (skin conductance) measures. The results show that emotional stress impacts decision making; in particular, emotionally aroused participants seem to have focused on the most important information and selected simpler decision strategies relative to participants in a control condition. The results are in line with the attention‐narrowing hypothesis and suggest that emotional stress can impact decision making through limited predecisional information search and the selection of simpler decision strategies.

不同背景下不同频率闪烁的突显工效研究 总被引:4,自引:0,他引:4
本实验对黑、白背景下高频、中频、低频三种闪烁的突显工效进行了比较研究。实验结果表明:闪烁作为突显类型可以提高视觉搜索的绩效,而且,在闪烁的频率较高时(27Hz以上),这种闪烁的突显工效更为明显。视觉材料的呈现背景对闪烁突显视觉搜索绩效没有明显的影响,但在白背景下采用闪烁效果较好。 相似文献

The 'war' between religion and science is winding down, creating new opportunities for fruitful dialogue. The foundations of indirect religion-science dialogue, where the perspectives of the two disciplines illuminate some third subject, are not well established. A detailed comparison of the Roman Catholic bishops' dialogues and a similar program within the American Association for the Advancement of Science illustrates the variety in formalscience-religion interactions and reveals much about the promise, achievements, and limitations of different approaches. Success depends in large part on controlling the diversity of the dialogue group, choosing topics carefully, and adopting positive and cooperative attitudes. 相似文献

生命意义的内涵、测量及功能 总被引:3,自引:0,他引:3
研究者通常用目的和含义来定义生命意义,或者把它定义为多维度的结构。认知、动机和情感是被提及最多的生命意义的组成维度。动机和认知维度得到了较多研究者的认可,而情感维度存在较大争议。生命意义是幸福不可或缺的元素,它能够影响许多与幸福有关的变量。目前的研究对生命意义的动机维度(生命意义寻求)及如何获得和提高生命意义研究较少,今后的研究可针对这两方面开展。 相似文献

Repeatedly encountering a visual search display with the target located at a fixed position relative to the distractors facilitates target detection, relative to novel displays – which is attributed to search guidance by (acquired) long‐term memory (LTM) of the distractor ‘context’ of the target. Previous research has shown that this ‘contextual cueing’ effect is severely impeded during learning when participants have to perform a demanding spatial working memory (WM) task concurrently with the search task, though it does become manifest when the WM task is removed. This has led to the proposal that search guidance by LT context memories critically depends on spatial WM to become ‘expressed’ in behaviour. On this background, this study, of two experiments, asked: (1) Would contextual cueing eventually emerge under dual‐task learning conditions if the practice on the task(s) is extended beyond the short training implemented in previous studies? and given sufficient practice, (2) Would performing the search under dual‐task conditions actually lead to an increased cueing effect compared to performing the visual search task alone? The answer is affirmative to both questions. In particular, Experiment 1 showed that a robust contextual cueing effect emerges within 360–720 dual‐task trials as compared to some 240 single‐task trials. Further, Experiment 2 showed that when dual‐ and single‐task conditions are performed in alternating trials blocks, the cueing effect for the very same set of repeated displays is significantly larger in dual‐task blocks than in single‐task blocks. This pattern of effects suggests that dual‐task practice eventually leads to direct, or ‘automatic’, guidance of visual search by learnt spatial LTM representations, bypassing WM processes. These processes are normally engaged in single‐task performance might actually interfere with direct LTM‐based search guidance. 相似文献

Job search represents a dynamic process through which job seekers must consistently engage in effective self-regulation. Although scholars have increasingly begun to theorize and conceptualize the job search in this manner, little is known about what fosters effective self-regulation week-to-week. In light of this theoretical gap, we integrate self-regulation theory with the feedback literature to examine how feedback quality influences affective, cognitive, and behavioral regulatory processes in job search. Furthermore, we examine feedback self-efficacy (i.e., how efficacious a job seeker feels with respect to processing and implementing feedback received during the job search) as a stable, person-level moderator of these within-person relationships. In a sample of job seekers surveyed once a week for seven weeks, results indicate that receiving high-quality feedback has a direct influence on positive and negative affective reactions tied to the job search, influencing subsequent positive (i.e., metacognitive strategies) and negative (i.e., affective rumination) cognitive processes. Metacognitive strategies, in turn, impact both the number of résumés sent and hours spent job seeking each week. Moreover, lower feedback self-efficacy amplifies the relationship between feedback quality and negative affective reactions. Our results highlight the importance of high-quality feedback in helping job seekers effectively regulate week-to-week. 相似文献

This two‐wave field study draws from social cognitive theory to investigate the specific job search self‐efficacy beliefs and behaviors of unemployed ethnic minority women in the Netherlands. We go beyond prior job search research that predominantly used white samples and conceptualized job search self‐efficacy and behavior as global, unidimensional constructs. We found that networking self‐efficacy and Internet self‐efficacy were the main predictors of ethnic minority women’s job search behaviors. Moreover, the more time they spent on contacting employment agencies and looking at job ads the more job offers they received. Finally, time spent on job ads was more positively related to job offers when job ad self‐efficacy was high and time spent on networking only predicted job offers when networking self‐efficacy was high. 相似文献

Searching for items in one’s environment often includes considerable reliance on semantic knowledge. The present study examines the importance of semantic information in visual and memory search, especially with respect to whether the items reside in long-term or working memory. In Experiment 1, participants engaged in hybrid visual memory search for items that were either highly familiar or novel. Importantly, the relatively large number of targets in this hybrid search task necessitated that targets be stored in some form of long-term memory. We found that search for familiar objects was more efficient than search for novel objects. In Experiment 2, we investigated search for familiar versus novel objects when the number of targets was low enough to be stored in working memory. We also manipulated how often participants in Experiment 2 were required to update their target (every trial vs. every block) in order to control for target templates that were stored in long-term memory as a result of repeated exposure over trials. We found no differences in search efficiency for familiar versus novel objects when templates were stored in working memory. Our results suggest that while semantic information may provide additional individuating features that are useful for object recognition in hybrid search, this information could be irrelevant or even distracting when searching for targets stored in working memory. 相似文献

We tested whether two known hemi-field asymmetries would affect visual search with face stimuli. Holistic processing of spatial configurations is better in the left hemi-field, reflecting a right hemisphere specialization, and object recognition is better in the upper visual field, reflecting stronger projections into the ventral stream. Faces tap into holistic processing and object recognition at the same time, which predicts better performance in the left and upper hemi-field, respectively. In the first experiment, participants had to detect a face with a gaze direction different from the remaining faces. Participants were faster to respond when targets were presented in the left and upper hemi-field. The same pattern of results was observed when only the eye region was presented. In the second experiment, we turned the faces upside-down, which eliminated the typical spatial configuration of faces. The left hemi-field advantage disappeared, showing that it is related to holistic processing of faces, whereas the upper hemi-field advantage related to object recognition persisted. Finally, we made the search task easier by asking observers to search for a face with open among closed eyes or vice versa. The easy search task eliminated the need for complex object recognition and, accordingly, the advantage of the upper visual field disappeared. Similarly, the left hemi-field advantage was attenuated. In sum, our findings show that both horizontal and vertical asymmetries affect the search for faces and can be selectively suppressed by changing characteristics of the stimuli. 相似文献
