The maintenance of information in visual working memory has been shown to bias the concurrent processing in favor of matching visual input. The present study aimed to examine whether this bias can act at an early stage of processing to enhance target feature perception in single-item displays. Participants were sequentially presented with two distinct colored stimuli as memory samples and a retro-cue indicating which of the two samples should be maintained for subsequent memory test. During the retention interval, they had to discriminate the gap orientation of a Landolt target presented through a single visual stimulus that could match one or neither of the two samples. Across two experiments, we consistently found that discrimination performance was more accurate when the Landolt target was situated within a stimulus that matched the sample being retained in visual working memory, as compared with when the target was not. This effect cannot be attributed to the mechanism of passive priming, because we failed to observe priming effects when the stimulus containing the target matched the sample that was retro-cued to be irrelevant to the working memory task, as compared to when the stimulus matched neither sample. Given the fact that target stimuli were presented in single-item displays wherein external noise was precluded, the present findings demonstrate that the working memory bias of visual attention operating in the absence of stimulus competition facilitates early perceptual processing at the attended location via signal enhancement.
The purpose of this study was to develop and validate a Christian-based Grief Recovery Scale (CGRS) which was used to measure Christians recovering from grief after a significant loss. Taiwanese Christian participants were recruited from churches and a comprehensive university in northern Taiwan. They were affected by both the Christian faith and Chinese cultural beliefs. The CGRS is developed through replicated factor analyses in three stages. The final version of the CGRS retains 35 Likert-type items and consists of six factors: spiritual well-being; recovering meaning and sense of control; ongoing physical and emotional responses; reassuring faith; strongly missing a deceased loved one; and life disturbance. The evidence for CGRS reliability and validity is highlighted. Implications for research and counselling practice are suggested. 相似文献
The present study investigates Taiwanese graduate students’ general understanding and misunderstanding of Responsible Conduct of Research (RCR). A total of 580 graduate students responded to the self-developed Responsible Conduct of Research Reasoning Test. The results reveal that, first, students did not have sufficient knowledge to reason why a particular instance of research (mis)conduct was doable or not. Second, the statistical results show that female students, students majoring in the humanities or the social sciences, doctoral-level students, and students with RCR-related training outperformed others. In addition, the misbehaviors that students judged relatively uncritically comprise the following nine categories: (a) seeing authorship as a property or power, (b) misinterpreting research coauthors’ responsibilities, (c) inaccurately conducting the informed-consent process, (d) fabricating and falsifying research data, (e) misinterpreting the correct citation of research sources, (f) holding vague concepts of self-plagiarism, (g) misinterpreting the Taiwan Copyright Act, (h) accepting duplicate-publication practices, and (i) accepting piecemeal publication practices. The present study discusses participative students’ major misunderstandings of actual RCR-related practices. The study also presents further implications and suggestions based on the findings. 相似文献
We report that <c+a> pyramidal slipping could be more easily activated in textured Mg–Ca alloys with increasing Ca contents dissolved in α-Mg matrix under tensile deformation, and it is proposed that the decreased stacking fault energy plays the critical rule. In contrast, only twins and <a> basal dislocations are observed in the compressed samples. The results would provide insight into understanding of the deformation mechanism and designing more ductile Mg alloys. 相似文献
Divergent thinking likely plays an important role in simulating autobiographical events. We investigated whether divergent thinking is differentially associated with the ability to construct detailed imagined future and imagined past events as opposed to recalling past events. We also examined whether age differences in divergent thinking might underlie the reduced episodic detail generated by older adults. The richness of episodic detail comprising autobiographical events in young and older adults was assessed using the Autobiographical Interview. Divergent thinking abilities were measured using the Alternative Uses Task. Divergent thinking was significantly associated with the amount of episodic detail for imagined future events. Moreover, while age was significantly associated with imagined episodic detail, this effect was strongly related to age-related changes in episodic retrieval rather than divergent thinking. 相似文献
