Status,testosterone, and human intellectual performance: stereotype threat as status concern 总被引:4,自引:0,他引:4
Results from two experiments suggest that stereotype-threat effects are special cases of a more general process involving the need to maintain or enhance status. We hypothesized thatsituations capable of confirming a performance stereotype might representeither a threat to status or an opportunity for enhancement of status,depending on the nature of the stereotype. The positive relationship betweenbaseline testosterone and status sensitivity led us to hypothesize that hightestosterone levels in males and females would amplify existing performanceexpectations when gender-based math-performance stereotypes were activated.In Study 1, high-testosterone females performed poorly on a math test when anegative performance stereotype was primed. In Study 2, high-testosteronemales excelled on a math test when a positive performance stereotype wasprimed. The moderating effect of testosterone on performance suggests that astereotype-relevant situation is capable of conferring either a loss or again of status on targets of the stereotype. 相似文献

Theorists commonly assume that true or primary psychopathic individuals experience little anxiety or neurotic conflict. This study examined the relationship between psychopathy and anxiety in 104 Caucasian and 113 African American incarcerated men using the Psychopathy Checklist--Revised (PCL-R; R. D. Hare, 1991) and multiple self-report measures to tap diverse interpretations of the anxiety construct (i.e., neuroticism, traditional definitions of anxiety, and fear). Analyses involving zero-order, semipartial, and point-biserial correlations indicate that PCL-R psychopathy and the anxiety construct are essentially independent. These findings suggest that either (a) the traditional belief that all psychopathic individuals are low-anxious is incorrect or (b) the PCL-R is not an adequate measure of primary psychopathy. 相似文献

Summary Auditory processing was examined in eight normal subjects using monotic and dichotic presentations of phonemic elements in an auditory backward recognition-masking paradigm. Experimental trials consisted of the presentation of one of three equiprobable consonant-vowel targets (/ba/,/da/,/ga/) followed by a vowel masker (/a/), separated by a variable silent interstimulus interval (ISI). For the dichotic condition, the mean percentage of correct recognition scores for target identification improved systematically with increases in ISIs, reaching an asymptote followed by an apparent plateau. In contrast, mean performance accuracy for the monotic condition revealed a U-shaped function for signal pairs having short temporal offsets. Although the dichotic presentations resulted in overall lower mean recognition scores, comparability between listening conditions was observed at prolonged ISIs. Observed differences in performance between the monotic and dichotic conditions at short-duration ISIs suggested the existence of different processing mechanisms, correlated with integration and interruption of phonemic pairs, for target-mask interactions occurring in close temporal succession. 相似文献

Co-occurrence of psychopathy (assessed with the Psychopathy Checklist) and lifetime Diagnostic and Statistical Manual of Mental Disorders (3rd ed.) alcohol and drug disorders (assessed with the National Institute of Mental Health Diagnostic Interview Schedule) was examined in a sample of 360 male inmates. Consistent with previous research that used diagnoses of antisocial personality disorder, psychopaths were more likely than nonpsychopaths to have lifetime diagnoses of alcoholism, any drug disorder, and multiple drug disorders. We also examined the relation between substance abuse and the 2 factors of the Psychopathy Checklist. Substance abuse was significantly related to general social deviance (Factor 2) but was unrelated to core personality features of psychopathy (Factor 1). We present two possible models of psychopathy (unitary syndrome vs. dual-diathesis model) that may account for the association between psychopathy and substance abuse. 相似文献

We conducted two studies to test and refine the hypothesis that, when undersocialized individuals focus on events of immediate interest, they allocate too large a proportion of their processing resources to those events and have little attention available for processing other important events. College students who completed the Socialization (So) scale (Gough, 1960) performed visual and auditory tasks simultaneously under conditions favoring the visual task, an equal division of processing resources between the tasks, or both. In both studies, low-So Ss performed relatively poorly on the auditory task under focusing conditions but displayed no primary task advantage and no significant performance deficits under divided attention conditions. These data support the utility of theories relating antisocial behavior to individual differences in allocation of attention. Low-So Ss' unresponsiveness to secondary events is not a simple function of the reallocation of resources to the primary task or a speed-accuracy trade-off. Moreover, under certain conditions, this deficit may disappear, given substantial practice. 相似文献

The impact of fingers on numerical and mathematical cognition has received a great deal of attention recently. However, the precise role that fingers play in numerical cognition is unknown. The current study explores the relationship between finger sense, arithmetic and general cognitive ability. Seventy-six children between the ages of 5 and 12 participated in the study. The results of stepwise multiple regression analyses demonstrated that while general cognitive ability including language processing was a predictor of addition performance, finger sense was not. The impact of age on the relationship between finger sense, and addition was further examined. The participants were separated into two groups based on age. The results showed that finger gnosia score impacted addition performance in the older group but not the younger group. These results appear to support the hypothesis that fingers provide a scaffold for calculation and that if that scaffold is not properly built, it has continued differential consequences to mathematical cognition. 相似文献

Adult Ss made distance bisection judgments over a surface on which the packing density of the texture elements was progressively increased along the Ss’ line of sight from one end of the surface to the other. Distance judgments were significantly different under monocular and binocular conditions of vision; however, with binocular vision, Ss did not detect the deformation in the texture on the surface. This result does not support predictions derived from Gibson, Purdy, and Lawrence (1955) concerning the role of gradients of binocular disparity in Gibson’s psychophysical theory of space perception. 相似文献

This paper describes examples of adolescent behavior which parents and school personnel find obnoxious. It attempts to explain why intelligent, reasonable and well-adjusted teenagers periodically behave in this way, as something that is developmentally inevitable given the uneven development of competencies in several important areas. Adolescent incompetencies in four areas (cognitive, social cognition, moral judgment, and knowledge of the world) are discussed and exemplified by resulting behavior (including the current Cabbage Patch doll fad). Suggestions for dealing positively with the sometimes difficult and exasperating behavior of adolescents are offered. 相似文献

How children learn to use memory strategies in a microgenetic investigation of learning and metacognition is examined. Seven- and eight-year-olds were given two memory trials with 24 pictures on each of 5 consecutive days. Days 1 and 2 were baseline, practice trials; Day 3 included strategy training; and Days 4 and 5 were unprompted tests of strategy maintenance. All children were taught how to label, rehearse, and group the pictures as well as to self-test their own memories and use blocked recall. Half of the children were shown the actions and told to do them; the other half received elaborated feedback on the usefulness and appropriateness of the techniques for remembering. The elaborated instructional group exhibited significantly greater recall, clustering, strategic study behavior, and metamemory regarding the mnemonic techniques than the other group. Path analysis provided evidence of a causal role of training and metacognitive awareness that mediated the use of sorting and higher recall. The study illustrates how learning the significance and utility of mnemonic techniques can influence children's acquisition of the tactics as self-controlled strategies. In addition, the microgenetic method affords patterns of data across time and experience that permit richer interpretations of strategy learning and memory development. 相似文献
