Previous research has suggested that the involuntary allocation of spatial attention to salient, irrelevant stimuli (i.e., attentional capture) is prevented when attention is in a focused state (e.g., Yantis & Jonides, 1990). Recent work has suggested that although focused attention may be necessary to prevent attentional capture by irrelevant stimuli, it is not sufficient (e.g., Folk, Leber, & Egeth, 2002). The present experiments provide evidence that attentional engagement, rather than attentional focusing, prevents capture. Observers performed a rapid serial visual presentation task in which they were asked to identify a target letter defined by color. Peripheral distractors that shared the color of the target produced evidence of attentional capture. This effect was completely eliminated, however, when the peripheral distractor was preceded by a central distractor designed to engage attention on the stream. It is concluded that attentional engagement serves to lock out capture by irrelevant, salient stimuli.  相似文献

How to keep children safe in traffic: find the daredevils early   总被引:1,自引:0,他引:1  
Crossing the street in front of oncoming vehicles poses serious danger to young children. But is each young pedestrian similarly at risk? The authors aimed to identify children who are particularly prone to making risky and potentially harmful crossing decisions. They used a simple game involving risk to classify 5- to 6-year-olds as risk takers or risk avoiders. Children classified as risk takers made more crossing decisions at a busy 1-way street than risk avoiders, tolerated shorter time intervals between initiation of the crossing decision and arrival of the next vehicle, and were more likely to cause a (hypothetical) accident. Finally, they made decisions more quickly than risk avoiders. The authors discuss the implication of these results for traffic safety programs.  相似文献

Many great authors claim that reading literature can expand your phenomenal imagination and allow you to imagine experiences you have never had. How is this possible? Your phenomenal imagination is constrained by your phenomenal concepts, which are in turn constrained by the phenomenology of your own actual past experiences. Literature could expand your phenomenal imagination, then, by giving you new phenomenal concepts. This paper explains how this can happen. Literature can direct your attention to previously unnoticed phenomenal properties of your own past experiences, as brought to mind by involuntary memory. This process gives you the opportunity to notice those phenomenal properties for the first time, and so also to form phenomenal concepts of those properties. Forming a new phenomenal concept strictly expands the range of your phenomenal imagination. It gives you the capacity to imagine more than you could have before, including certain specific kinds of experience that you yourself have never enjoyed firsthand. Literature’s capacity to expand your phenomenal imagination in this way is central to its social, moral, and epistemic value.  相似文献

Drawing attention to historic increases in equality carries the risk of encouraging complacency about the need to further advance equality. This risk may be reduced by carefully framing the interpretation of increased equality. We apply an influential goal-framing model (Fishbach and Zhang, 2008) to test whether framing the accomplishments of the American Civil Rights Movement in terms of progress toward equality vs. commitment to equality influences white Americans' support for further egalitarian policies. In two experiments, we manipulated whether progress or commitment was in mind when participants considered civil rights accomplishments. As hypothesized, participants more strongly supported egalitarian policies when civil rights accomplishments were framed as evidence of commitment to equality than when these same accomplishments were framed as evidence of progress toward equality. We discuss implications for applying the goal-framing model to political goals and the advantages of using experimental methods to study framing processes in social movements.  相似文献

The nature of processes underlying our perception of reversible figures was examined through two experiments investigating the effects of prior exposure conditions on an observer's report of figural reversal. In experiment 1, observers were adapted over several minutes to an unambiguous version of a rotating Necker cube prior to the presentation of the standard ambiguous figure. Results indicated that adaptation produced an immediate bias to perceive the ambiguous figure in the opposite configuration (ie reverse bias) and to reduce reports of reversal over the test period. The introduction of a brief delay between the adaptation and test periods revealed that this bias is a highly transient effect and is only clearly evident when the adaptation and test figures are matched in size. In experiment 2, observers were primed with an unambiguous figure for a few seconds prior to the presentation of the standard ambiguous figure. In this case, the obtained bias strongly favored the observer's reporting the ambiguous figure to be in the same configuration as the adapting figure (ie positive bias); and neither introducing a delay period nor changing figure size had any effect. We conclude that these experiments reveal the distinct roles of transient, retinally localized neural processes as well as more stable, global processes under specifiable conditions.  相似文献

People frequently have to control their emotions to function in life. However, mounting evidence suggests that deliberate emotion regulation often is costly. This presents a dilemma: Is it better to let emotions go or to pay the price of exerting costly control? In two studies, the authors explore whether emotion regulatory processes associated with implicit positive evaluation of emotion regulation might provide the benefits of successful emotion regulation without the costs. In Study 1, the authors introduce a measure of implicit evaluation of emotion regulation (ER-IAT). Study 2 examined whether this measure is associated with actual emotional responses to an anger provocation. It was found that greater ER-IAT scores were associated with lesser anger experience, fewer negative thoughts, lessened self-reported effortful emotion regulation, and an adaptive pattern of cardiovascular responding. These findings suggest that implicit positive evaluation of emotion regulation is associated with successful, automatic, and physiologically adaptive down-regulation of anger.  相似文献

粥食养生     
粥,在我国地不分南北,人不分老幼,大都喝过。然而吃粥的学问并非人人知晓。粥,有多少品种,现今尚未见到精确统计,大体说,从原料分,有谷、肉、蛋、果、菜等粥;从浓稀上分,有厚有薄;从食用上分,有素、荤、药等粥。历史上研究养生者都非常重视粥食。故古代有“粥乃世间第一补人之物”的说法。  相似文献

Theories proposing that how one thinks and feels is influenced by feedback from the body remain controversial. A central but untested prediction of many of these proposals is that how well individuals can perceive subtle bodily changes (interoception) determines the strength of the relationship between bodily reactions and cognitive-affective processing. In Study 1, we demonstrated that the more accurately participants could track their heartbeat, the stronger the observed link between their heart rate reactions and their subjective arousal (but not valence) ratings of emotional images. In Study 2, we found that increasing interoception ability either helped or hindered adaptive intuitive decision making, depending on whether the anticipatory bodily signals generated favored advantageous or disadvantageous choices. These findings identify both the generation and the perception of bodily responses as pivotal sources of variability in emotion experience and intuition, and offer strong supporting evidence for bodily feedback theories, suggesting that cognitive-affective processing does in significant part relate to "following the heart."  相似文献

This study aimed to investigate whether career competencies could enhance an employee's subjective career success in terms of perceived employability and work–home balance via job crafting behaviors. Based on Job Demands‐Resources (JD‐R) Theory, we examined a potential motivational process in which career competencies, as a personal resource, would enhance career success through expansive job crafting. The results showed that job crafting mediated the positive relationship between career competencies and both internal and external perceived employability. In addition, job crafting mediated the positive relationship between career competencies and work–home enrichment. We expected a negative association between job crafting and work–home interference, yet our results indicated that career competencies are indirectly and positively related to work–home interference via job crafting. With our findings, we add to JD‐R Theory by (1) showing that career competencies may be considered a personal resource, (2) empirically examining the role of job crafting in motivational processes, and (3) showing that enhanced subjective career success can be an outcome of motivational processes. Organisations may use these findings to implement developmental HR practices aimed at increasing career competencies and job crafting.  相似文献

Body movements both express and influence how people feel and think. Conceptualizations of this bidirectional influence assume that movement-concept associations can be innate or learned, although evidence for learned associations remained ambiguous. Providing a conservative test of learned movement-concept associations, two studies investigate the influence of culture-specific body movements, which involve an arbitrary relationship between movements and associated concepts. Paralleling the influence of hostility primes, extending the middle finger influenced the interpretation of ambiguously aggressive behaviors as hostile, but did not influence unrelated trait judgments (Study 1). Paralleling the effects of global evaluative primes, upward extension of the thumb resulted in more positive evaluations of the same target along all trait dimensions and higher liking of the target (Study 2).  相似文献
