It is well known that stimuli grab attention to their location, but do they also grab attention to their sensory modality? The modality shift effect (MSE), the observation that responding to a stimulus leads to reaction time benefits for subsequent stimuli in the same modality, suggests that this may be the case. If noninformative cue stimuli, which do not require a response, also lead to benefits for their modality, this would suggest that the effect is automatic. We investigated the time-course of the visuotactile MSE and the difference between the effects of cues and targets. In Experiment 1, when visual and tactile tasks and stimulus locations were matched, uninformative cues did not lead to reaction time benefits for targets in the same modality. However, the modality of the previous target led to a significant MSE. Only stimuli that require a response, therefore, appear to lead to reaction time benefits for their modality. In Experiment 2, increasing attention to the cue stimuli attenuated the effect of the previous target, but the cues still did not lead to a MSE. In Experiment 3, a MSE was demonstrated between successive targets, and this effect decreased with increasing intertrial intervals. Overall, these studies demonstrate how cue- and target-induced effects interact and suggest that modalities do not automatically capture attention as locations do; rather, the MSE is more similar to other task repetition effects.  相似文献

This article examines the role the public imagination of the state has in maintaining the current political status quo in Burjatija, an east Siberian Republic. Based on a quantitative and interpretative analysis of Burjatija??s local newspapers, it uses the ??centre-versus-periphery?? paradigm to identify varying representations of the Republic??s territorial community in government legitimization discourse, before discussing their assimilation into popular newspaper discourse. Multiple narratives of Burjatija and the Russian Federation exist in these newspapers, incorporating various centres and peripheries. I end by discussing the nature of the state these newspapers reveal, and the function the dissemination of alternative centres and peripheries has within it.  相似文献

The present study examined perceptions of racial discrimination and racial socialization on racial identity development among 566 African American adolescents over 3 years. Latent class analyses were used to estimate identity statuses (Diffuse, Foreclosed, Moratorium, and Achieved). The probabilities of transitioning from one stage to another were examined with latent transition analyses to determine the likelihood of youth progressing, regressing, or remaining constant. Racial socialization and perceptions of racial discrimination were examined as covariates to assess the association with changes in racial identity status. The results indicated that perceptions of racial discrimination were not linked to any changes in racial identity. Youth who reported higher levels of racial socialization were less likely to be in Diffuse or Foreclosed compared with the Achieved group.  相似文献

Interventions to reduce car use have shown limited success, in part due to limitations in models of transport choices. The theory of planned behavior (TPB) has provided a useful predictive model of car use but the specific beliefs that underpin TPB‐specified cognitions are less well understood. In this study, 229 university employees responded to a questionnaire and then reported their commuting choices 1 week later. Intention and perceived behavioral control (PBC) predicted car use (R2 = .79). Intention was predicted by attitude, subjective norm, PBC, and moral norm (R2 = .56). Beliefs could not be differentiated into attitudinal and PBC constructs, but seven beliefs predicted TPB cognitions. A similar model was tested for public transport use. The results identify key targets for future interventions.  相似文献

In the present article, we report a series of studies examining the links between attachment orientations and compassion fatigue among volunteers working with traumatized individuals. Participants were volunteers in several trauma‐related organizations, ranging in age from 18 to 69 years. In Study 1 (N = 148), we examined associations between self‐reports of attachment insecurities and compassion fatigue. In Study 2 (N = 54), we used a diary design to assess attachment‐related differences in emotional reactions to actual helping encounters over a 2‐month period. In Study 3 (N = 108), we examined the effects of the experimental enhancement of attachment security (security priming) on reactions to a hypothetical helping encounter. As expected, attachment insecurities, either anxiety or avoidance, were associated with heightened compassion fatigue. Moreover, security priming reduced compassion fatigue in response to a hypothetical helping encounter. These findings underscore the relevance of attachment theory for understanding and preventing compassion fatigue.  相似文献

Test–retest and construct validity of Contour Drawing Rating Scale (CDRS) scores were examined in 1056 Grades 7 and 8 girls. Questionnaires were completed four times, including retests at 2, 6 and 14 weeks. Test–retest reliability for current size, ideal size and current–ideal discrepancy mostly exceeded 0.70 (0.65–0.87, for the full sample, with higher rs for shorter retest periods). Ideal and current size ratings increased slightly over time. High correlations between perceived current figure and measured body mass index; moderate rs between current–ideal discrepancy and body dissatisfaction and restrained eating; and very low or no significant correlations with social desirability supported construct validity in this group. The study supported the use of the CDRS in early adolescent girls.  相似文献

An overview of current dimensions of group psychotherapy practice by psychiatric-mental health nurses is presented. The relationship between graduate education and the characteristics of the nurses' current practice is demonstrated. The psychiatric-mental health nurse's involvement in the general health care arena with nonpsychiatric populations is highlighted. Future trends for the practice of group by nurses is explicated and projected. In addition, implications for the education and practice of other group practitioners is drawn.Marianne DiMinno, R.N., M.S.N., assisted in the development of the survey questionnaire.  相似文献

This study was designed to assess the changes that have occurred in the portrayals of black people and cross-racial relationships in prime-time television broadcasting during the past decade. By replicating the content analysis procedures used by Weigel, Loomis, and Soja (1980), this investigation provided a consistent basis for comparing two similar samples of television content drawn, respectively, from 1978 and 1989. Results of this comparison indicated that, although black appearances and cross-racial interactions were no more frequent in the 1989 sample of product commercials, the black presence in prime-time programming had increased substantially. As compared to 1978, the proportion of time that one or more black characters were on the screen more than doubled, while the frequency of cross-racial interactions more than tripled in the 1989 sample. Nevertheless, ratings of qualitative dimensions of these cross-racial interactions suggested that relationships between blacks and whites on television continued to be portrayed as cooperative but emotionally detached, particularly when the relationships occurred outside of the work place.  相似文献

In response to a series of allegations of scientific misconduct in the 1980’s, a number of scientific societies, national agencies, and academic institutions, including Harvard Medical School, devised guidelines to increase awareness of optimal scientific practices and to attempt to prevent as many episodes of misconduct as possible. The chief argument for adopting guidelines is to promote good science. There is no evidence that well-crafted guidelines have had any detrimental effect on creativity since they focus on design of research studies, documentation of research findings, assignment of credit through authorship, data management and supervision of trainees, not on the origin and evolution of ideas. This paper addresses a spectrum of causes of scientific misconduct or unacceptable scientific behavior and couples these with estimates of the potential for prevention if guidelines for scientific investigation are adopted. The conclusion is that clear and understandable guidelines should help to reduce the chance that flawed research will escape from our institutions. However, they cannot be relied upon alone to prevent all instances of scientific misconduct and should be regarded rather as one means of bolstering the integrity of the entire scientific enterprise.  相似文献
