An experiment tested the effects of dyad membership and the prospect of completing a motor‐skills task on alcohol placebo consumption and task confidence. Participants (n = 115) completed a taste preference task while alone or in dyads. Half the individuals and half the dyads expected to subsequently complete a motor‐skills task and rated task confidence pre and post‐consumption. Individuals expecting the task consumed less than those in the non‐task condition and felt less confident in their abilities post‐consumption. Among those expecting the task, dyad members' consumption did not reduce and their post‐consumption confidence was higher than individuals'. Findings suggest dyad membership can lead to overconfidence. Attempts to reduce alcohol related harms must balance the protective properties of dyads with risks of overconfidence. 相似文献

This study examines the role of perceived phenotypic racial stereotypicality and race-based social identity threat on racial minorities’ trust and cooperation with police. We hypothesize that in police interactions, racial minorities’ phenotypic racial stereotypicality may increase race-based social identity threat, which will lead to distrust and decreased participation with police. Racial minorities (Blacks, Latinos, Native Americans, and multi-racials) and Whites from a representative random sample of city residents were surveyed about policing attitudes. A serial multiple mediation model confirmed that racial minorities’ self-rated phenotypic racial stereotypicality indirectly affected future cooperation through social identity threat and trust. Due to the lack of negative group stereotypes in policing, the model did not hold for Whites. This study provides evidence that phenotypic stereotypicality influences racial minorities’ psychological experiences interacting with police. 相似文献

Anti‐atheist prejudice is pervasive worldwide. Past research indicates that this is driven by perceptions of atheist immorality, yet such perceptions have not been explored in detail. Using Moral Foundations Theory and samples of U.S. Christians, we investigated whether anti‐atheist prejudice is explained by atheists' perceived adherence to certain foundational moral values more than others. Study 1 participants completed measures of moral value endorsements from the perspective of a typical atheist. Study 2 participants read that either atheists or people in general strongly endorse one of five moral foundations. Anti‐atheist prejudice was consistently explained best by perceived atheist concern for values of caring/compassion rather than fairness/justice, loyalty, deferential respect, or purity/decency. Findings suggest that efforts to reduce anti‐atheist prejudice should emphasize atheists' capacity for kindness and caring. 相似文献

Disordered sleep is strongly linked to future depression, but the reasons for this link are not well understood. This study tested one possibility – that poorer sleep impairs emotion regulation (ER), which over time leads to increased depressive symptoms. Our sample contained individuals with a wide range of depression symptoms (current depression, N?=?54, remitted depression, N?=?36, and healthy control, N?=?53), who were followed clinically over six months and reassessed for changes in depressive symptom levels. As predicted, maladaptive ER mediated both cross-sectional and prospective relationships between poor sleep quality and depression symptoms. In contrast, an alternative mediator, physical activity levels, did not mediate the link between sleep quality and depression symptoms. Maladaptive ER may help explain why sleep difficulties contribute to depression symptoms; implications for interventions are discussed. 相似文献

The article describes results from two studies that examined the psychometric properties of a measure of irrational thinking, the Child and Adolescent Scale of Irrationality (CASI), based on the model of REBT. Participants were 1034 children and parents recruited through schools and clinical settings. While the internal consistency of the total scale was quite high, the reliability of the proposed irrational subscales were considerably lower and an exploratory factor analysis failed to yield interpretable factors. Discriminative validity was demonstrated between subjects in clinical settings and school-based subjects on the total scale score and two of the irrational subscales. The total scale score and irrational subscales were correlated with ratings of behavior and emotion, with higher irrationality being correlated with higher levels of emotional and behavioral disturbance. Overall, while problems exist with the factor structure and reliability of the irrational subscales, the CASI appears to adequately measure irrational beliefs. Therefore, it may be clinically useful as a screener when working with children and adolescents. 相似文献

An emerging literature suggests that poor executive control (EC) may be associated with clinical weight problems, e.g., body mass index (BMI) for age percentile ≥85 in children. However, our understanding of the impact of EC on overweight and obesity in childhood is limited by the lack of longitudinal studies spanning critical developmental periods and assessing EC using comprehensive performance-based batteries. The current study addresses these limitations in a longitudinal examination of 212 children who completed an extensive laboratory-based EC task battery in preschool (age 4 years and 6 months) and were followed through elementary school (Grades 1 through 4) with objective measures of weight status. The logistic regression results indicate that poorer EC in preschool is associated with significantly greater risk for clinical weight problems (either overweight or obese status, as defined by BMI-for-age percentile ≥ 85) in elementary school, controlling for maternal education. EC in preschool was not significantly associated with risk for obese status, specifically (defined by BMI-for-age percentile ≥ 95), but the trend was in the expected direction. The results suggest that early executive abilities are relevant for children’s subsequent health status, with deficits in EC in the critical period of preschool conferring risk for later problems with weight. Based on these findings, early interventions to promote stronger EC may be a promising, yet currently overlooked, component in pediatric obesity prevention efforts. 相似文献

Children are at risk for cognitive difficulties following the diagnosis and treatment of a brain tumor. Longitudinal studies have consistently demonstrated declines on measures of intellectual functioning, and recently it has been proposed that specific neurocognitive processes underlie these changes, including working memory, processing speed, and attention. However, a fine-grained examination of the affected neurocognitive processes is required to inform intervention efforts. Radiation therapy (RT) impacts white matter integrity, likely affecting those cognitive processes supported by distributed neural networks. This study examined working memory and attention in children during the early delayed stages of recovery following surgical resection and RT. The participants included 27 children diagnosed with pediatric brain tumor, treated with (n = 12) or without (n = 15) RT, who completed experimental and standardized measures of working memory and attention (n-back and digit span tasks). Children treated with radiation performed less well than those who did not receive radiation on the n-back measure, though performance at the 0-back level was considerably poorer than would be expected for both groups, perhaps suggesting difficulties with more basic processes such as vigilance. Along these lines, marginal differences were noted on digit span forward. The findings are discussed with respect to models of attention and working memory, and the interplay between the two. 相似文献

Background and objectives: Attention control deficits and repetitive negative thinking (RNT; i.e., rumination) may be key factors in the development and persistence of depression and anxiety, although their role in symptom development remains poorly understood. This represents a gap in the literature, as interventions targeting attention control and associated RNT may enhance interventions and prevent costly relapse. The current study was designed to examine the serial indirect effects of transdiagnostic RNT and negative affect recovery following a lab-induced stressor on the association between attention control deficits and trait anxiety and depression.Methods: Participants were N?=?583 university students who completed validated measures of RNT, anxiety, depression, and mood ratings pre- and post-stressor. Stress was induced using a modified version of the Trier Social Stress Test.Results: Results of cross-sectional indirect effects models indicated that RNT and mood recovery explained the association between attention control deficits and trait anxiety and depression. Results from reversed models indicated that only the indirect effect of RNT was significant.Conclusions: Findings suggest that RNT and mood recovery processes play an important role in explaining anxiety and depression symptoms. Additional work is needed to examine their role in symptom development and maintenance over time. 相似文献

Activity level (AL) is a highly salient feature of child behaviour that has been linked to developmental outcome. Twin studies of parent‐rated, observer‐rated and mechanically assessed AL in childhood find that AL is genetically influenced. Few studies, however, consider whether different methods of assessing AL have a shared genetic etiology. Those that do, confound methods and situations. The present study examined whether actigraph and rater‐based (parent, observer) measures of AL tap the same genetic influences in a sample of 312 2‐year‐old twin pairs. Methods were studied within the same situation, thereby controlling for situational influences on AL. The genetic correlation between actigraph and parent‐rated AL in the home was .38, indicating modest genetic overlap between the two methods. In contrast, the correlation of genetic effects on actigraph and observer‐rated AL in the laboratory was .95, indicating that both laboratory‐based measures of AL are influenced by the same genetic effects. 相似文献

Complex social stimuli (like faces) can be studied using a methodology typically reserved for studying lights, tones, and
colors: psychophysics. Given that psychophysics examines how humans detect and respond to stimuli in their environment, we
can extend that to the study of how humans detect social stimuli in the environment. Using psychophysical methodology to answer
“social” questions provides another dimension of experimental manipulation and control to the diverse array of methodologies
already used by social psychologists. In this article, we review psychophysical methodology, provide a rationale for social
psychophysics, describe an easy-touse software program called PsychoPro, for collecting psychophysical data, and present data
collected using this program to examine racial thresholds that provide evidence for a cognitive gating mechanism for racial
information that impacts face processing (MacLin & MacLin, 2007, in press; MacLin, MacLin, & Peterson, 2008). 相似文献
