We conducted a targeted review of the literature exploring racial phenotypicality bias (RPB): perceivers' sensitivity to within-race variation in facial target features in perceptions and judgment of others. This review revealed evidence that two distinct mechanisms underlying these effects, categorical and featural, tend to be conflated in the literature. The categorical route suggests that the pathway from target cues to stereotype application is mediated by category activation. The featural route suggests that the pathway from target cues to stereotype application is direct, bypassing category activation. The categorical route is more closely represented when researchers discuss RPB, and more often of empirical focus. With a focus on research exploring RPB toward African American people, we explain the two routes and evidence supporting their distinction. We next offer evidence estimating the degree to which they may be conflated in the empirical literature and discuss limitations to our approach. Next, we describe some potential implications of this conflation for theory, research, and applications concerning RPB. Finally, we end with some recommendations for future empirical research.  相似文献

The purpose of this research note is to summarize the available data on trends in religious attendance across 24 European countries to determine whether a base level has been reached in some countries. We focus on the changes observed in the period 1990–2012. After critically assessing the data quality of the recent European Social Survey (ESS) and European Values Study (EVS), we present four different methods of assessing current trends. First, we assess intercohort differentials, an indicator previously used extensively. We then look at trends in young people's rates of attendance, followed by trends of the postwar cohorts born in 1950–1981. We proceed to an appraisal of individual life‐course variations by looking at attendance as a child and young adult. A compilation of these indicators shows that they often do not fully agree on whether there is growth, decline, or stability. To generalize, the high‐attending Catholic countries are more likely to exhibit religious decline, whilst a few ex‐communist countries are seeing sustained growth. The most secular countries seem to be generally stabilizing in the 5–20 percent range for attendance rates of the postwar generations.  相似文献

This study examined whether adolescents communicate about antisocial topics and behaviors via text messaging and how adolescents’ antisocial text message communication relates to growth in rule-breaking and aggression as reported by youth, parents, and teachers. Participants (n?=?172; 82 girls) received BlackBerry devices configured to capture all text messages sent and received. Four days of text messages during the 9th grade year were coded for discussion of antisocial activities. The majority of participants engaged in at least some antisocial text message communication. Text messaging about antisocial activities significantly predicted increases in parent, teacher, and self-reports of adolescents’ rule-breaking behavior, as well as teacher and self-reports of adolescents’ aggressive behavior. Text message communication may provide instrumental information about how to engage in antisocial behavior and reinforce these behaviors as normative within the peer group.  相似文献

Depression is often characterized by attentional biases toward negative items and away from positive items, which likely affects reward and punishment processing. Recent work has reported that training attention away from negative stimuli reduced this bias and reduced depressive symptoms. However, the effect of attention training on subsequent learning has yet to be explored. In the present study, participants were required to learn to maximize reward during decision making. Undergraduates with elevated self-reported depressive symptoms received attention training toward positive stimuli prior to performing the decision-making task (n = 20; active training). The active-training group was compared to two other groups: undergraduates with elevated self-reported depressive symptoms who received placebo training (n = 22; placebo training) and a control group with low levels of depressive symptoms (n = 33; nondepressive control). The placebo-training depressive group performed worse and switched between options more than did the nondepressive controls on the reward maximization task. However, depressives that received active training performed as well as the nondepressive controls. Computational modeling indicated that the placebo-trained group learned more from negative than from positive prediction errors, leading to more frequent switching. The nondepressive control and active-training depressive groups showed similar learning from positive and negative prediction errors, leading to less-frequent switching and better performance. Our results indicate that individuals with elevated depressive symptoms are impaired at reward maximization, but that the deficit can be improved with attention training toward positive stimuli.  相似文献

ABSTRACT

This cross-sectional field study examines the influence of employee and spousal characteristics on employees’ career-related motivations in dual ladder systems. We go beyond “constraints-based” explanations of spousal influence and focus on the degree to which the spouse has aspirations for the focal employee’s career – referred to as spousal career aspirations. Using a dyadic study design, we tested a model that specifies the influence of both partners’ career salience and materialism on an employee’s motivation for a particular career path: as manager or technical specialist. According to survey responses from a matched sample of 207 employees and their spouses, the spouse’s career salience and materialism (the latter only for women) were associated with higher levels of spousal career aspirations. In turn, those employees whose spouses aspired for them to have a career were less motivated to obtain a specialist position. Employees’ own career salience was positively associated with their motivation for a managerial position and, in combination with high levels of spousal career aspirations, pulled employees away from a career on the technical ladder. Our results shed light on the family-relatedness of career decisions and have notable implications for dual ladder organizations.  相似文献

Weight-based self-esteem (WBSE) is hypothesized to be the core cognitive feature of eating disorders. The Weight Influenced Self-Esteem Questionnaire (WISE-Q) was designed to measure the influence of a negatively perceived body image on multiple dimensions of self-esteem, which we believe to be one aspect of WBSE. Study 1 sought to determine the factor structure of the WISE-Q as well as to examine the reliability and concurrent validity of WISE-Q scores among eating disorder and undergraduate student participants. In Study 2, validity was further investigated by examining changes in WISE-Q scores with treatment. The WISE-Q has two factors representing generalized and expected WBSE. Evidence of internal and test–retest reliability was found. Also, the pattern of correlations between WISE-Q scores and other constructs was in line with predictions. As expected, WISE-Q scores improved with treatment yet remained high.  相似文献

People with symptoms of depression show impairments in decision-making. One explanation is that they have difficulty maintaining rich representations of the task environment. We test this hypothesis in the context of exploratory choice. We analyze depressive and non-depressive participants’ exploration strategies by comparing their choices to two computational models: (1) an “Ideal Actor” model that reflectively updates beliefs and plans ahead, employing a rich representation of the environment and (2) a “Naïve Reinforcement Learning” (RL) model that updates beliefs reflexively utilizing a minimal task representation. Relative to non-depressive participants, we find that depressive participants’ choices are better described by the simple RL model. Further, depressive participants were more exploratory than non-depressives in their decision-making. Depressive symptoms appear to influence basic mechanisms supporting choice behavior by reducing use of rich task representations and hindering performance during exploratory decision-making.  相似文献

Two studies done from constructivist perspectives were considered for their complementarity in understanding the development of gifted young artists. Study 1 used Case's (1992) neo-Piagetian theory as a framework and investigated the developmental progression in ability to represent spatial relations in children aged 4,6,8, and I0 years. Children identified as gifted demonstrated some advancement in their use of perspective but were distinguished primarily by their elaborate and novel representations of space. An age-related progression in acquisition of ability to render perspective supports a general factor in development, whereas abilities unique to the artistic domain support the relevance of including domain-specific characteristics in developmental models of giftedness. Study 2 was done primarily from a structuralist perspective but also incorporated a postformal perspective on the problem-finding and problem-solving behaviors of young artists aged I3 to 18 years. There was support for age-related domain-general aspects of thought with discipline-specific skills in making multiple comparisons in proportional relations and coordinating multiple perspectives. This finding may be an extension of young children's intrastage elaboration of the spatial structures available to them.  相似文献

Abstract

This study examined differences in diabetes-specific locus of control beliefs of 82 insulin-treated Type I diabetes patients undergoing either conventional therapy (CT), intensified conventional therapy (ICT) or continuous subcutaneous insulin infusion (CSII). Compared to CT with its adherence to a strict regimen, ICT and CSII allow a much greater flexibility in timing of meals and daily activities. On the other hand, such flexibility requires a much more active role of the patient. The hypotheses of higher internality and lower powerful others locus of control beliefs in ICT and CSII patients than in CT patients could be supported for powerful others locus of control only. A one-year follow-up replicated this finding. Furthermore, high powerful others locus of control was associated with low diabetes-related knowledge and poor glycaemic control. The relevance of the patients' experience with the respective treatment is examined in view of the results and implications for studies on the feasibility of diabetes regimens are discussed.  相似文献
