Proposals for regulating or nudging healthy choices are controversial. Opponents often argue that individuals should take responsibility for their own health, rather than be paternalistically manipulated for their own good. In this paper, I argue that people can take responsibility for their own health only if they satisfy certain epistemic conditions, but we live in an epistemic environment in which these conditions are not satisfied. Satisfying the epistemic conditions for taking responsibility, I argue, requires regulation of this environment. I describe some proposals for such regulation and show that we cannot reject all regulation in the name of individual responsibility. We must either regulate individuals’ healthy choices or regulate the epistemic environment.  相似文献

The outbreak of COVID-19 is affecting the lives of millions of families around the world. The current study was carried out in Israel, following the pandemic’s initial outbreak and during the resulting enforced quarantine, confining parents and children to their homes. A sample of 141 Israeli mothers with at least one child between the ages of 3 and 12 (M?=?6.92, SD?=?2.55) participated as volunteers. About half the sample (50.7%) consisted of girls. Most mothers were cohabiting with a spouse (93%). Mothers completed online questionnaires about their perceptions about the health and economic threats of COVID-19, availability of social support, their anxiety symptoms, hostile/coercive and supportive/engaged parenting behavior, and their children’s behavior problems. Results showed expected significant associations between the mothers’ reports about having little social support, their anxiety symptoms, hostile/coercive and supportive/engaged parenting behavior, and children’s externalizing problems. Likewise, expected significant associations were found between mothers’ perceptions about the health and economic threats of COVID-19, their anxiety symptoms, hostile/coercive parenting behavior, and children’s internalizing and externalizing problems. Importantly, maternal anxiety and hostile/coercive parenting behavior mediated the associations between lack of support, negative perceptions about the health and economic threats of COVID-19, and children’s behavior problems. These findings stress the importance of mothers’ mental health and parenting behaviors for children’s socioemotional adaptation in the context of COVID-19. Implications of the findings for family interventions intended to help parents and children at this time are suggested.

ABSTRACT

This article focuses on Black girls/adolescents, a frequently neglected group, given a dominant focus on Black males and their risk status within the school-to-prison pipeline. This article provides a framework for the analysis of the gendered violence to which Black girls/adolescents are subjected while urging a shift in focus from individual-level behavior to a focus on social contextual, structural, and social determinant factors; this means a shift from focusing on proximal factors to distal or upstream factors operating as underlying mechanisms. Both illustrative data and cases are presented and analyzed to highlight how racial disparities in suspension, expulsion, and discipline—which disproportionately negatively impact Black girls/adolescents compared to White girls/adolescents—necessitate a major call to action to close these disturbing gaps.  相似文献

Race schematicity, memories for racially stereotyped portrayals, and race-based peer preferences of 70 young children (32 African American, 38 White) were assessed. Consistent with schema-based models of stereotyping, race schematicity was positively and significantly associated with memory distortions of racial stereotype-inconsistent drawings into stereotype-consistent ones. Conversely, race schematicity was negatively and significantly associated with accurate memories for racial stereotype-inconsistent content, and with memory distortions of racial stereotype-consistent portrayals into stereotype-inconsistent ones. As predicted, race schematicity was positively and significantly associated with same-race peer preference bias, as was children's age in months. Results support application of the schematicity construct and relevant social psychological research with adults to the study of young African American and White children's racial stereotyping and processing of race-relevant information.  相似文献

We present a new account of the fine-grained structure of semantic categories derived from neuropsychological, behavioral, and developmental data. The account places theoretical emphasis on the functions of the referents of concepts. We claim (i) that the distinctiveness of functional features correlated with perceptual features varies across semantic domains; and (ii) that category structure emerges from the complex interaction of these variables. The representational assumptions that follow from these claims make strong predictions about what types of semantic information are preserved in patients showing category-specific deficits following brain damage. These claims are illustrated with a connectionist simulation which, when damaged, shows patterns of preservation of distinctive and shared functional and perceptual information which varies across semantic domains. The data model both dissociations between knowledge for artifacts and for living things and recent neuropsychological evidence concerning the robustness of functional information in the representation of concepts.  相似文献

The Community Alcohol Use Scale (CAUS) was developed as a continuous, reliable, valid, and acceptable measure for primary prevention studies. Items were written following a comprehensive review of the literature on alcohol dependence and alcoholism. Based upon the responses of 315 respondents to the 100-item initial version of the scale, the 45-item CAUS was developed. The CAUS was then cross-validated on a local sample (n = 274) and a provincial sample (n = 745). Estimates of internal consistency were .91, .96, and .94, respectively, for the initial and cross-validation samples. Correlations of .48 and .69 were obtained between the CAUS and the Michigan Alcohol Screening Test for the initial and local cross-validation samples. In the provincial cross-validation sample a correlation of .62 was obtained between the CAUS and the Usual Weekly Alcohol Index. Preliminary cutting scores were developed to identify those at risk for alcoholism, and alcoholics. The CAUS has potential use as an evaluative and predictive instrument in a variety of primary prevention programs.  相似文献

We examined 40 left-handers and 40 right-handers on two free-vision tests of face processing. A chimeric face composed of a smiling half-face joined to either a neutral half-face (real faces) or a sad half-face (cartoon faces) and its mirror image were presented on each trial. Subjects judged which chimeric face looked happier, the one with the smile to the left or the one with the smile to the right. Right-handers, but not left-handers, had a highly significant leftward attentional bias, since chimeras with the smile to the left were judged happier than those with the smile to the right. The cartoon- and real-face tasks did not differ in the mean perceptual asymmetries they elicited. However, correlations between attentional-asymmetry scores for the two tasks, although high for both left- and right-handers, were significantly smaller than task reliabilities. Thus, the cartoon- and real-face tasks overlap to a major extent in the lateralized processes they measure, but to a lesser extent, they also index different lateralized processes.  相似文献

Thirty-two teachers rated Type A behavior, using Matthews Youth Test for Health, (MYTH) and negative characteristics of hyperactivity, negative peer relations, social withdrawal, and depression in 105 children, between the ages of 6 and 11, from lower to middle class Black and White families. Children's age, gender, race, and socioeconomic status (SES) and teachers' gender, grade taught, and years of teaching experience were not related to teachers' MYTH ratings. However, White teachers rated children higher on Type A behavior than Black teachers. Controlling for teacher race effects, MYTH total scores, rather than reflecting a global negative view of the child, showed a strong overlap with hyperactivity and were differentiated from social withdrawal and depression. The MYTH Impatience/Aggression factor was highly related to hyperactivity and negative peer interactions; the Competitiveness factor was associated with a lack of social withdrawal. The conclusions verify the multidimensional nature of children's Type A behavior pattern and the importance of rater demographic characteristics in the assessment of children's behavior.  相似文献

Sex differences in the lateralized processing of facial emotion   总被引:4,自引:2,他引:2  
Two reaction time tasks were administered to male and female normal subjects, involving judgments of facial emotion. In the Word-Face task, judgments of similarity or difference of a centrally presented emotion word and an emotional face presented in the left or right visual field were required, and in the Face-Face task, comparisons of a centrally presented and a laterally presented emotional face were required. Results were significant for the matching trials only. Reaction times to negative emotions were faster overall than to positive emotions, and an Emotional Valence by Visual Field interaction was found such that reaction times were faster for negative emotions in the left visual field and for positive emotions in the right visual field. This interaction was significant for the female but not the male subjects, although similar patterns were observed in both sexes. Further, an interaction of Gender, Task, and Emotional Valence was found, such that the two tasks had opposite effects for the two sexes. The Face-Face task appeared to inhibit the performance of the male subjects and facilitate the performance of the female subjects in terms of reaction time. It was suggested that specifying the target emotion by an emotional face elicits a greater emotional response on the part of the subject than specification by a word, and that this emotional elicitation may result in a reactive inhibition in the male subjects and in an elaboration of the emotional response in the female subjects.  相似文献
