Snakes are among the most common targets of fears and phobias around the world. In visual search tasks, both adults and young children have repeatedly been found to visually detect snakes more rapidly than other kinds of stimuli. An important question that remains unstudied is what accounts for humans’ rapid response to snakes? Here we suggest that specific features of snakes themselves lead to their rapid detection. The results of five experiments suggest that a snake's shape is the crucial factor in their rapid detection. 相似文献

Threatening facial expressions like anger can signal potential danger. Past research has established that both adults and children have an attentional bias for angry faces, visually detecting their presence more quickly than happy or neutral faces. More recent research has suggested that specific features of angry faces (such as the downward-pointing “V” shaped brow) are the effective stimulus in their rapid detection. However, research examining this issue has only been done with adults. In the current research, we examine the detection of the features of the downward-pointing “V” in both adults and preschool children using a touchscreen visual search procedure. In two experiments, both adults and children detected the downward-pointing “V” more quickly than an upward-pointing “V”. As the first evidence that young children exhibit the same superior detection of the features of threatening facial expressions that adults do, this research provides important support for the existence of an evolved attentional bias for threatening stimuli. 相似文献

Examining the Effects of Social Bonds and Shame on Drug Recovery within an On-Line Support Community
Past research has demonstrated the utility of on-line support groups for individuals to form relationships and make connections. Additionally, some on-line communities have expanded to provide various types of support, particularly for deviant behavior. These virtual communities may be particularly indispensable to individuals who, out of fear of condemnation, are reluctant to seek traditional forms of social support. For purposes of this study, we examined how members of a substance abuse recovery on-line support group expressed feelings pertaining to their own substance abuse, as well as their processes of attempted or successful recovery. Using an inductive approach for our preliminary analysis, we first assessed which theories were most prevalent throughout the writers’ journals. We then used these theories, both Hirschi’s theory of social control and Braithwaite’s theory of reintegrative shaming, as frameworks to explore the differences between those who were in recovery and those who were still using. 相似文献

Resonating with understandings prevalent among White Americans, psychologists tend to portray racism as a problem of individual prejudice rather than a systemically embedded phenomenon. An unintended consequence of this portrayal is to reproduce a narrow construction of racism as something that does not require energetic measures to combat. We describe 2 studies that provide support for this idea. Tutorials presented the topic of racism either as individual prejudice (standard condition) or as a systemic phenomenon embedded in American society (sociocultural condition). Results confirmed that perception of racism and (in Study 2) endorsement of antiracist policy were greater among participants in the sociocultural tutorial condition than among participants in the both the standard tutorial and no-tutorial control conditions. An ironic consequence of standard pedagogy may be to promote a modern form of scientific racism that understates the ongoing significance of racist oppression. 相似文献

A series of studies tested whether people underestimate the likelihood that others will comply with their direct requests for help. In the first 3 studies, people underestimated by as much as 50% the likelihood that others would agree to a direct request for help, across a range of requests occurring in both experimental and natural field settings. Studies 4 and 5 demonstrated that experimentally manipulating a person's perspective (as help seeker or potential helper) could elicit this underestimation effect. Finally, in Study 6, the authors explored the source of the bias, finding that help seekers were less willing than potential helpers were to appreciate the social costs of refusing a direct request for help (the costs of saying "no"), attending instead to the instrumental costs of helping (the costs of saying "yes"). 相似文献

A central goal in cognitive and developmental science is to develop models of behavior that can generalize across both tasks and development while maintaining a commitment to detailed behavioral prediction. This paper presents tests of one such model, the Dynamic Field Theory (DFT). The DFT was originally proposed to capture delay-dependent biases in spatial recall and developmental changes in spatial recall performance. More recently, the theory was generalized to adults' performance in a second spatial working memory task, position discrimination. Here we use the theory to predict a specific, complex developmental pattern in position discrimination. Data with 3- to 6-year-old children and adults confirm these predictions, demonstrating that the DFT achieves generality across tasks and time scales, as well as the specificity necessary to generate novel, falsifiable predictions. 相似文献

We compared the effectiveness of a problem‐solving and an external control intervention to teach social skills to two adults with mild intellectual disabilities. Each participant received the problem‐solving intervention with one social skill and the external control intervention with another social skill. The comparative effectiveness of the social skill training protocols was evaluated using individual participant alternating treatment designs. Overall, there seemed to be little difference between the interventions in terms of acquisition, generalization, or maintenance of social skills with either participant. Limitations of the current study and issues for future research are discussed. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

There is uncertainty whether the sexes differ with respect to their mean levels and variabilities in mental ability test scores. Here we describe the cognitive ability distribution in 80,000+ children—almost everyone born in Scotland in 1921—tested at age 11 in 1932. There were no significant mean differences in cognitive test scores between boys and girls, but there was a highly significant difference in their standard deviations (P<.001). Boys were over-represented at the low and high extremes of cognitive ability. These findings, the first to be presented from a whole population, might in part explain such cognitive outcomes as the slight excess of men achieving first class university degrees, and the excess of males with learning difficulties. 相似文献
