One-month-old infants were tested with a habituation-recovery paradigm to determine whether they could discriminate phase-shifting grating patterns that switched between two orientations, three or eight times a second, from grating patterns that only shifted in phase. The infants were found to discriminate patterns switching orientation at the lower temporal rate of 3 reversals s-1, but not 8 reversals s-1. This finding supports the idea that orientation-selective mechanisms improve in their temporal sensitivity during early infancy. Where they can be compared, the results from behavioural and electrophysiological studies agree as to the course of this development. 相似文献
This paper builds on Stebbins' (1996) concept of tolerable differences, an underused tool for analysis of deviant activities and lifestyles that tend not to elicit the kind of collective condemnation traditionally reserved for serious moral and legal transgressions. Our analysis centers on two case studies of criminal tolerable deviance in Canada, the widespread use of marijuana for recreational purposes and the illegal ticket scalping trade. Whereas the former has inspired a vast body of literature, the latter has been thus far overlooked by sociologists. Consideration of the two together, in terms of Stebbins' framework, betters our understanding of the social construction of these practices, further developing theory and research on deviance more generally. 相似文献
Abstract An intervention strategy is presented which can be used with families of adolescents who continue breaking the law despite improvement of family functioning during therapy. The strategy emphasizes collaboration between the therapist and juvenile justice system in stopping the child's law-breaking behavior in the shortest amount of time. The treatment strategy is suggested as a specific intervention to be used only when conventional family therapy strategies have failed to promote the cessation of the adolescent's law-breaking behavior. As such, it is suggested as a strategy to be used in conjunction with family therapy rather than as a comprehensive treatment approach in itself. 相似文献
Since the early 1990s, Canadian women have participated in tattooing in unprecedented numbers. These women are utilizing tattoo body projects (C. Shilling, 1993) to communicate a wide range of personal and cultural messages, and challenging the long-standing association between tattooing and masculinity. However, and perhaps more consequentially, women's tattoo projects express diverse sensibilities about femininity and the feminine body. For some Canadian women, contesting culturally established (N. Elias & J. Scotson, 1965) constructions of the female body is central in their tattoo body projects, whereas others participate in tattooing as an explicit form of consent to such constructions. In this paper, women's tattooing activities and their subsequent tattoo narratives are critically inspected as deeply gendered practices and discourses. I present participant observation and interview data on tattoo enthusiasm in Canada. The focus is directed toward the ways in which conformity to, resistance against, and the negotiation of established cultural ideas about femininity are equally embedded in women's tattooing. Drawing upon feminist theories about bodies (cf. S. Bordo, 1990; K. Davis, 1994; J. Price & M. Shildrick, 1999; S. Williams & G. Bendelow, 1998) and central tenets of process-sociology (N. Elias, 1991, 1994, 1996; N. Elias & J. Scotson, 1965), emphasis is given to how women employ tattooing as a communicative signifier of established and outsider constructions of femininity. 相似文献
Critical requirements for the hypothesis that executive functioning is a potential mediator of age-related effects on cognitive functioning are that variables assumed to reflect executive functioning represent a distinct construct and that age-related effects on other types of cognitive functioning are reduced when measures of executive functioning are statistically controlled. These issues were investigated in a study involving 261 adults between 18 and 84 years of age. Although age-related effects on various cognitive abilities were substantially reduced after statistical control of the variance in measures hypothesized to represent executive functioning, there was only weak evidence for the existence of distinct constructs corresponding to executive functioning or to aspects of executive control concerned with inhibition, updating, or time sharing. 相似文献
The central premise of attachment theory is that the security of the early child-parent bond is reflected in the child's interpersonal relationships across the life span. This meta-analysis was based on 63 studies that reported correlations between child-parent attachment and children's peer relations. The overall effect size (ES) for child-mother attachment was in the small-to-moderate range and was quite homogeneous. ESs were similar in studies that featured the Strange Situation and Q-sort methods. The effects were larger for peer relations in middle childhood and adolescence than for peer relations in early childhood. ESs were also higher for studies that focused on children's close friendships rather than on relations with other peers. Gender and cultural differences in ESs were minimal. The results for the few studies on father-child attachment were inconclusive. 相似文献
Existing instruments for measuring Asian American acculturation emphasize behavior acculturation to the exclusion of value acculturation. Most are based on the assumption that acquisition of European American behavior occurs simultaneously with the loss of Asian behavior. With the advent of the Asian Values Scale (AVS; B.S.K. Kim, D.R. Atkinson, & P.H. Yang, 1999), it is now possible to assess adherence to Asian cultural values. This article describes the development of a scale that can be used to measure Asian American adherence to European American values. The current scale, combined with the AVS, can be used to independently measure Asian American acculturation to European American values and enculturation in Asian values. 相似文献
Although men and women help others, there are systematic gender differences in the type of helping they perform. Consistent with traditional gender roles and stereotypes, men typically help in agentic ways, and women typically help in communal ways. Drawing on the Theory of Planned Behavior, the Gender Roles Inhibiting Prosociality model predicts that gender stereotypes about gender-inconsistent helping create negative attitudes, restrictive subjective norms, and low self-efficacy that undermine helping intentions, which, in turn, reduce engagement in gender-inconsistent helping contexts. Across three studies (N?=?1,355), we find empirical support for the hypothesized model: When asked to imagine engaging in a gender-inconsistent (vs. gender-consistent) helping scenario, participants anticipated feeling worse, expected others to judge them more negatively, and reported decreased self-efficacy beliefs, and these factors predicted lower intentions to engage in gender-inconsistent helping. Critically, behavioral intentions explained some of the variance in gender-inconsistent helping during the following month. Internal meta-analyses of the differences between gender-consistent and -inconsistent helping on attitudes, subjective norms, self-efficacy, and behavioral intentions across studies revealed small-to-medium average effect sizes (ds?=?0.16—0.47). These results have the potential to inform interventions aimed at increasing helping in all its forms.
