A judgement analysis of people's social inferences of attitudes and ability was conducted. University students were asked to infer the liberalness (N = 60; Study 1) or intelligence (N = 40; Study 2) of targets seen in pictures. Multiple regression analyses revealed that attractiveness was the most important cue for predicting inferences of liberalness, while an ethnic cue (i.e., being Asian) was the most important cue for judgements about intelligence. Results also showed that a single-cue model was less susceptible to overfitting, but significantly less accurate than a multiple-cue model in predicting participant's intelligence judgements. Although the multiple regression models suffered a degree of overfitting, cross validation showed that they continued to have significant predictive value when applied to new data. Furthermore, a “random partner” method (comparing each participant's own regression equation with that of another, randomly selected, participant) provided evidence of significant idiosyncratic variation in the way intelligence judgements were made.  相似文献

The current study aimed to investigate whether the correlation between rumination and suicidal ideation is moderated by the presence of hope and optimism. It was hypothesized that both hope and optimism would moderate (weaken) the relationship between rumination and suicidal ideation. Two hundred and ninety-eight participants completed self-report measures of hope, optimism, rumination (brooding and reflection), and depression. Results demonstrated that both hope and optimism weakened the relationship between rumination and suicidal ideation, as well as the relationships between both subscales of rumination and suicidal thinking. These results were found when controlling for symptoms of depression. Results suggest that a ruminative thinking style may be most harmful when an absence of hope or optimism is also present.  相似文献

The degree to which collinear lines are treated as a unit in resolving rotary motion in depth was investigated with the use of parallel projection to make direction of motion ambiguous. The proportion of time that the collinear lines appeared to rotate in the same direction was used as an index of their perceptual coherence. When the gap between the lines was small, there was strong grouping of the lines with respect to direction of motion as well as appearance of rigidity for the configuration. For larger gaps the grouping for direction of motion was maintained, but the lines appeared to have different axes of rotation leading to an appearance of nonrigidity. It is concluded that line elements can be aggregated for the resolution of certain properties without constituting a unit in any general sense.  相似文献

Decades of empirical work have confirmed that experiences with violence are associated with a variety of adverse behavioral and mental health as well as academic outcomes for children and adolescents. Yet this research largely has relied on indirect measures of exposure. In this study, we apply geospatial analysis to examine the relation between neighborhood violent crime (via police reports) and academic performance (via school-level standardized test proficiency rates). Findings suggest that greater numbers of crimes proximal to school buildings relate to lower levels of academic performance. These results persisted even when controlling economic disadvantage in the student body. Implications for research and policy are discussed.  相似文献

The current study examined patterns of coping strategies in a sample of 497 low-income urban African American adolescents (mean age = 12.61 years). Results of confirmatory factor analysis indicated that the 4-factor structure of the Children's Coping Strategies Checklist (T. S. Ayers, I. N. Sandler, S. G. West, & M. W. Roosa, 1996) was not replicated in the current sample. The final model was a 3-factor model that was invariant across gender. The Active Coping factor and Revised Avoidant Coping factor were highly correlated in the present sample. Results of cluster analyses identified 2 coping groups differing on the frequency of coping use and preferred coping methods. The 1st group was more likely to use avoidant coping and less likely to use social support-seeking coping than the 2nd group, which showed more consistent use across coping strategies. There were no significant differences in the association between stressors and symptoms across the 2 groups. The results highlight the importance of examining factor structures of coping measures with underrepresented groups.  相似文献

Central nervous system (CNS) vasculitis is a rare entity, especially when it occurs in isolation; it is seen more commonly as part of a multisystem vasculitis. Common presenting symptoms include persistent headache, encephalopathy, and multifocal signs. We discuss the case of a 68-year-old female who presented twice in 1 month with confusion and choreaform movements. Extensive workup was negative for a connective tissue disease or other conditions in the differential, including neurosarcoidosis, Creutzfeldt-Jakob disease, and neurosyphilis. The only significant findings were elevated erythrocyte sedimentation rate, inflammatory signs in the CNS, and diffuse slowing of the electroencephalogram. A presumptive diagnosis of isolated angiitis of the central nervous system (IACNS) was made and the patient was successfully treated with steroids. She recovered fully with no residual symptoms. The diagnosis of IACNS is often difficult given there are no definitive laboratory investigations or pathognomonic presentation. However, a series of signs, symptoms, and laboratory findings have been proposed that are helpful in making the diagnosis. To our knowledge, IACNS presenting primarily with delirium has not been previously reported in the literature. The diagnosis of IACNS is purely speculative for this case, as the gold standard for diagnosis, a leptomeningeal cortical biopsy, was not performed.  相似文献

The primary purpose of this study was to examine the synchronous and temporal relations between engagement in activities and the two primary dimensions of affect—namely, positive and negative affect—using an intensive time-series design called concomitant time series analysis (CTSA). Twenty-four dementia caregivers completed 56 diary measures (4 times per day for 2 weeks) assessing their experience of positive and negative affect as well as engagement in a variety of activities. Total number of activities was significantly correlated with positive affect (r = .40), but not negative affect (r = -.12). Obtained pleasure from activities was significantly correlated with both positive (r = .42) and negative affect (r = - .17). These results may help further develop behavioral models of depression by suggesting that behavioral or self-reinforcing activities are associated primarily (or more saliently) with one's experience of positive affect. Future research examining the effect of behavioral interventions on both positive and negative affect is suggested, as is the examination of factors that may be more strongly associated with negative affect.  相似文献
