Both real-world category knowledge and instance-based sample data are often available as sources of inductive inference. In
three experiments using natural social categories, we test the influence of general category knowledge on the use of category
instances to make property inductions both to other category members and to others in the population. We find that a category’s
coherence—the extent to which its features are interrelated through prior knowledge (Murphy & Medin, 1985)—influences inductions
positively to new category members and negatively to the population. This effect of coherence is strongest with small as compared
with large samples of instances. The results are interpreted from both similarity and explanation-based perspectives. 相似文献

Differences in ingroup identification can influence the accessibility of historical memories. In Study 1, the authors examined individual differences in identity; in Study 2 they experimentally manipulated identity. In Study 1, high identifiers recalled fewer incidents of ingroup violence and hatred than did low identifiers. High and low identifiers did not differ in their recall of ingroup suffering. In Study 2, participants in the high-identity condition recalled fewer incidents of violence and hatred by members of their group than did those in the low-identity condition but a similar number of good deeds. Control participants recalled more positive than negative group actions; this bias was exaggerated in the high-identity condition and eliminated in the low-identity condition. The authors interpret the results as indicating the effects of social identity on individual-level memory processes, especially schema-consistent recall. They evaluate other explanations of the bias, including collective censorship of negative histories. 相似文献

When one looks up a hill from below, its peak appears lower than it is; when one looks at a hill across a valley from another peak, the peak of that hill appears higher than it is. These illusions have sometimes been explained by assuming that the subjective horizontal is assimilated to the nearby slope: when looking up a slope, the subjective horizontal is raised, diminishing the height of the peak above the subjective horizontal, and making the peak appear lower than it is. When looking down a slope towards another hill, the subjective horizontal is lowered, increasing the height of that hill above the subjective horizontal, and making its peak appear higher than it is. To determine subjective horizontals we measured visually perceived eye levels (VPELs) in 21 real-world scenes on a range of slopes. We found that VPEL indeed assimilates by about 40% to slopes between 7 degrees downhill and 7 degrees uphill. For larger uphill slopes up to 23 degrees, VPEL asymptotes at about 4.5 degrees. For larger downhill slopes, the assimilation of VPEL diminishes, and at 23 degrees is raised by about 1 degree. These results are consistent with the assimilation explanation of the illusions if we assume that steep downhill slopes lose their effectiveness by being out of view. We also found that VPEL was raised when viewing from a height, in comparison with ground-level views, perhaps because the perceived slope increases with viewing height. 相似文献

Two research groups have raised the possibility that magical ideation may be a fundamental feature of obsessive-compulsive disorder. It has been proposed to underlie thought action fusion and superstitious beliefs. In this study, the Magical Ideation scale, the Lucky Behaviours and Lucky Beliefs scales, the Thought Action Fusion-Revised scale, the Padua Inventory, and the Obsessive Compulsive Inventory-Short Version were completed by 60 obsessive compulsive patients at a hospital clinic. Of all the measures, the Magical Ideation (MI) scale was found to be the most strongly related to obsessive compulsive symptoms. Large and significant relationships between MI scores and the measures of OCD were obtained even when alternative constructs (Lucky Behaviours, Lucky Beliefs, Thought Action Fusion-Revised scales) were held constant. No other variable remained significantly related to the Obsessive Compulsive Inventory-Short Version when magical ideation scores were held constant. The findings suggest that a general magical thinking tendency may underpin previous observed links between superstitiousness, thought action fusion and OCD severity. 相似文献

In a sample composed of 147 undergraduates (age range 18 to 55 years; M = 22), we conducted an examination of the convergent and discriminant validity of self- and other-forgiveness in the Five-factor model of personality (FFM). Using multiple measures of each construct, principal components analysis (PCA) supported a 2-component model of forgiveness. Findings for the PCA and external correlates with the FFM provided evidence for a largely orthogonal relationship between self- and other-forgiveness. Specifically, self-forgiveness was negatively related to Neuroticism and unrelated to Agreeableness, whereas other-forgiveness was unrelated to Neuroticism and positively related to Agreeableness. Overlap between the constructs was found in which both self- and other-forgiveness were negatively related to the hostility facet of Neuroticism and the order facet from Conscientiousness and positively related to the warmth and positive emotions facet scales from the Extraversion domain of the Revised NEO Personality Inventory (Costa & McCrae, 1992). Overall, these findings suggest that self- and other-forgiveness, although seemingly similar, carry very different motivational underpinnings. 相似文献

Although the emotional and motivational characteristics of dreaming have figured prominently in folk and psychoanalytic conceptions of dream production, emotions have rarely been systematically studied, and motivation, never. Because emotions during sleep lack the somatic components of waking emotions, and they change as the sleeper awakens, their properties are difficult to assess. Recent evidence of limbic system activation during REM sleep suggests a basis in brain architecture for the interaction of motivational and cognitive properties in dreaming. Motivational and emotional content in REM and NREM laboratory mentation reports from 25 participants were compared. Motivational and emotional content was significantly greater in REM than NREM sleep, even after controlling for the greater word count of REM reports. 相似文献

The single category implicit association test as a measure of implicit social cognition 总被引:7,自引:0,他引:7
The Single Category Implicit Association Test (SC-IAT) is a modification of the Implicit Association Test that measures the strength of evaluative associations with a single attitude object. Across 3 different attitude domains--soda brand preferences, self-esteem, and racial attitudes--the authors found evidence that the SC-IAT is internally consistent and makes unique contributions in the ability to understand implicit social cognition. In a 4th study, the authors investigated the susceptibility of the SC-IAT to faking or self-presentational concerns. Once participants with high error rates were removed, no significant self-presentation effect was observed. These results provide initial evidence for the reliability and validity of the SC-IAT as an individual difference measure of implicit social cognition. 相似文献

The authors examined the relationships among gender, alcohol consumption, and parental monitoring, including television monitoring. Student volunteers (N = 150; 90% Caucasian, 79% women) participated by reporting retrospective general parental monitoring, television monitoring, and recent drinking behaviors. On the basis of the retrospective reports by the participants, when they were growing up the men received less overall parental monitoring but not less television monitoring than the women. Women's drinking quantity was correlated with parental monitoring, whereas men's drinking frequency was associated with both parental monitoring and television monitoring. Interestingly, men's binge drinking frequency was correlated with television monitoring but not with overall parental monitoring, whereas women's binge drinking frequency was correlated with overall parental monitoring but not with television monitoring. Implications for preventing alcohol misuse and ideas for future research are discussed. 相似文献

Through a telling of key events in the history of the “Teen Action Center” (TAC), a drop-in youth center located in downtown “Unionville,” this story demonstrates how ‘youth’ is an important diversity category. The community conflict highlighted in this story centers around the 1997 arrest of TAC's Executive Director and two youth leaders (all Puerto Rican) because a small group of Latino and African-American youth was smoking cigarettes on the sidewalk in front of the Center. This conflict brings into focus divergent views on where Unionville's youth of color belong in the city, both physically and figuratively. The lessons learned in this story have wide application as Unionville, and other cities undergoing demographic transformation and economic decline, are likely to continue to experience these types of clashes, where the dominant paradigm of economic development overrides the realities, rights, and interests of marginalized groups.This article has been adapted from a chapter in my dissertation (Ross, 2002) Rebuilding Communities, Shaping Identities: The Impact of a Participatory Neighborhood Planning Process on Young, Low-Income Adolescents of Color, completed at the University of Massachusetts-Boston Public Policy Program. I am a White, female middle class faculty member at a small private university. I remain connected to “TAC” as a Board member. Names have been changed to protect the identity of the participants. Names of data sources (newspapers) have been modified to protect the identity of the study location. 相似文献
