Six location-cuing experiments were conducted to examine the goal-driven control of attentional capture in multiple-cue displays. In most of the experiments, the cue display consisted of the simultaneous presentation of a red direct cue that was highly predictive of the target location (the unique cue) and three gray direct cues (the standard cues) that were not predictive of the location. The results indicated that although target responses were faster at all cued locations relative to uncued locations, they were significantly faster at the unique-cue location than at the standard-cue locations. Other results suggest that the faster responses produced by direct cues may be associated with two different components: an attention-related component that can be modulated by goal-driven factors and a nonattentional component that occurs in parallel at multiple direct-cue locations and is minimally affected by the same goal-driven factors. 相似文献

Stein, London, Wilkinson, and Price (1996) reported the presence of cross-modal enhancement of perceived visual intensity: Participants tended to rate weak lights as brighter when accompanied by a concurrent pulse of white noise than when presented alone. In the present study, two methods were used to determine whether the enhancement reflects an early-stage sensory process or a later-stage decisional process, such as a response bias. First, enhancement was eliminated when the noise accompanied the light on only 25% versus 50% of the trials. Second, enhancement was absent when tested with a paired-comparison method. These findings are consistent with the hypothesis that the sound-induced enhancement in judgments of brightness reflects a response bias, rather than an early sensory process--that is, enhancement is the result of a relatively late decisional process. 相似文献

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

In two experiments, we investigated the relationship between semantics and phonology in the lexical decision task. In the first experiment, lexical decisions to words with large semantic neighborhoods were faster than those to words with sparse semantic neighborhoods. Conversely, this effect of semantic neighborhood was reversed for pseudohomophones (e.g., nale). That is, pseudohomophones based on words with large semantic neighborhoods took longer to reject than did those based on words with sparse semantic neighborhoods. In the second experiment, we found the magnitude of the semantic neighborhood effect for words to be a function of nonword foil type. Taken together, these results indicate that semantic neighborhood size affects processing of both words and pseudohomophones, and that the effect of semantic neighborhood size for words is more pronounced when pseudohomophone foils are employed. These effects are discussed in terms of a model in which the orthographic, phonological, and semantic systems are fully interactive. 相似文献

Cerebral white matter abnormalities and lifetime cognitive change: a 67-year follow-up of the Scottish Mental Survey of 1932 总被引:5,自引:0,他引:5
Cerebral white matter abnormalities relate to cognitive functioning in elders. We examine whether this association is (a) independent of mental ability in youth and (b) related to general and/or specific mental abilities. We retested 83 participants of the Scottish Mental Survey of 1932 on a battery of mental tests. Their brains were scanned by magnetic resonance imaging. Three independent ratings (Fazekas) were made of periventricular, and subcortical and deep white matter abnormalities. Structural equation models showed that, irrespective of brain location, white matter abnormalities contributed about 14% of cognitive function variance in old age. Some of this effect might be due to hypertension. This contribution is independent of mental function in early life and is associated with general cognitive ability. 相似文献

Facets of dynamic positive affect: differentiating joy, interest, and activation in the positive and negative affect schedule (PANAS) 总被引:1,自引:0,他引:1
Egloff B Schmukle SC Burns LR Kohlmann CW Hock M 《Journal of personality and social psychology》2003,85(3):528-540
This article proposes the differentiation of Joy, Interest, and Activation in the Positive Affect (PA) scale of the Positive and Negative Affect Schedule (PANAS; D. Watson, L. A. Clark, & A. Tellegen, 1988). Study 1 analyzed the dynamic course of PA before, during, and after an exam and established the differentiation of the three facets. Study 2 used a multistate-multitrait analysis to confirm this structure. Studies 3-5 used success-failure experiences, speaking tasks, and feedback of exam results to further examine PA facets in affect-arousing settings. All studies provide convincing evidence for the benefit of differentiating three facets of PA in the PANAS: Joy, Interest, and Activation do have distinct and sometimes even opposite courses that make their separation meaningful and rewarding. 相似文献

Researchers surveyed the psychological well-being of 795 women of reproductive age from Menoufiya, Egypt. Five years earlier, these women had provided data relevant to their family planning behavior. This analysis links these data sets to investigate the impact of family planning on women's sense of well-being, within the context of beliefs about appropriate gender-related behaviors. Well-being measures are derived for trait and state dimensions. Use of family planning and number of children born within the preceding 5 years predicted state ratings of happiness, and number of children predicted anxious pride. Neither are related to any of the trait ratings. Further, 3 different gender-role attitudes are vital to the explanation of how women define and feel good about themselves. 相似文献

Gender-role conflict exists when gender roles have negative consequences for people. This research reports initial validity and reliability data on measures of gender-role conflict for men. Two measures, Gender Role Conflict Scale I and II (GRCS-I and GRCS-II) were constructed to assess patterns of gender-role conflict described in the literature. GRCS-I assesses men's personal gender-role attitudes, behaviors, and conflicts. GRCS-II assesses men's gender-role conflicts in specific gender-role conflict situations. Both GRCS measures and the Personal Attributes Questionnaire (PAQ) were administered to male college students (N=527). Initial factor-analytic data for GRCS-I and GRCS-II demonstrated eight meaningful factors. Acceptable test-retest and internal consistency reliabilities were found for both measures. MANOVA, ANOVA, and Tukey procedures indicated differences for subjects across the four PAQ categories. Significant gender-role conflict differences across the factors were found for men who were instrumental, expressive, or both instrumental and expressive. Results of these differences are reported, as well as implications for future development of both scales.The authors are indebted to Dr. Nancy Betz (Ohio State University) who generously gathered data for us during the Spring Semester, 1982. This research was supported by a grant from the General Research Fund of the University of Kansas, Lawrence, Kansas. This paper was presented at the American Psychological Association Annual Convention, Washington, DC, August 26, 1982. 相似文献

The purposes of this study were (a) to compare families with low (n = 47) and high (n = 44) levels of preseparation interparent conflict on mothers' report of paternal involvement (frequency, regularity, and length of visitation as well as regular payment of child support), children's adjustment, and mothers' level of stress; (b) to intercorrelate the four dimensions of paternal involvement; and (c) to relate the four dimensions of paternal involvement to children's age, children's gender, length of parental separation, children's adjustment, mothers' stress, paternal investment in the children, degree of environmental change, and children's level of interpersonal understanding. Children's mean age was 10.24 years, and parents had been separated a mean of 13.15 months. Compared to fathers in low-conflict families, fathers in high-conflict families visited less regularly and were less regular in their payment of child support. Mothers reported more adjustment problems for children in high-conflict families. All four dimensions of paternal involvement were intercorrelated only for high-conflict families. For both low- and high-conflict families, paternal involvement was related to paternal investment in the child but was unrelated to children's age, children's gender, and length of separation. Paternal involvement was most frequently related to children's adjustment in high-conflict families. For low-conflict families, paternal involvement was related low environmental change and children's well-developed interpersonal understanding skills. 相似文献

This research note describes a job analysis study which was conducted for the purpose of deriving selection standards for entry-level management jobs in a public utility. It is aimed toward practitioners with the responsibility of conducting legally-defensible job analyses. Each step of the study was guided by the legal and professional guidelines on testing and selection (viz.,Uniform Guidelines, 1978;Principles, 1986;Standards, 1985). Procedures employed to identify job content, job groups, the importance of various work behaviors, and a set of important knowledge, skills, abilities, and personal characteristics (KSAPs) are described.The authors would like to thank the following individuals for their help in the data collection phase of the study described here: Kimberly Clark, Lynn Clark, Gary Hayes, Candice Poole, Susan Rizhaupt, Phillip Randall, Sheri Elmore, and Ann Money. 相似文献
