To explore the hypothesis that people who migrate across international, provincial, and state borders tend to veer away from occupations that require intense social interaction, demographic data were obtained on 2,638 North Americans who have attained eminence within their chosen fields. Occupations were blind-coded either as "social" or "nonsocial." While there were similar concentrations in social occupations among Native Americans (75.00%) and Native Canadians (73.02%), there were successively fewer social occupations among Canadian emigres (59.53%), world (predominantly European) emigres (51.46%), and Asian emigres (40.99%) to the U.S. Findings suggest that Asian Americans' well-documented tendencies to veer away from lines of work that involve forceful self-expression reflects a continuous variable rather than a dichotomous variable that sharply separates Asian and North American cultures.  相似文献

We examine the relationship between demographics and adherence to certain religious traditions within American Christianity. Starting with Niebuhr's Social Sources of Denominationalism , we interact with a long scholarly tradition that connects demographics and religious groups, particularly the abiding "class-sect" relationship. Included in this literature are works by Roof and McKinney (1987), and the particular profiles of evangelicals by Hunter (1983) and more recently by Smith et al. (1998). Findings indicate slow convergence on certain demographics highlighted by Niebuhr (social class, region, population size), and slow divergence on other demographics (age, percent female, percent married, number of children). Contrary to previous research, evangelical Protestantism is not very distinct demographically; however, black Protestantism is, and this reflects the continued demographic significance of race. Our findings lead us to question accepted theoretical links between demographics and religious groups. We end with some preliminary recommendations for future theorizing in this area.  相似文献

The research in this article explores the structure and content of attributed intergroup beliefs: to what extent do perceivers think others of their ingroup and their outgroup display intergroup evaluative bias and outgroup homogeneity? We report studies that address this question in ethnicity, gender, and nationality intergroup contexts. In all of these, we show that perceivers attribute to others more biased intergroup beliefs than they themselves espouse. Even when perceivers themselves do not show intergroup bias or outgroup homogeneity, they attribute such biases to others, both others from their ingroup and others from their outgroup. We argue that such attributed intergroup beliefs are fundamentally important to expectations concerning intergroup interaction. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

As human possess powerful incest-avoidance mechanisms (which likely evolved due to the high costs of inbreeding), reactions to incestuous sexual encounters may be psychologically distinct from reactions to non-incestuous (but still non-normative) sexual encounters. Accordingly, variables such as sex and sociosexuality that normally predict openness to sexual encounters in other situations (i.e., men and sociosexually unrestricted people tend to be more sexually willing) may not do so – or do so only weakly – in incestuous situations. In Study 1, sociosexuality predicted negative judgments of non-incestuous (but still normatively proscribed) sexual acts, but not judgments of incestuous sexual acts. In Study 2, sociosexuality predicted negative reactions to imagined sex with biologically unrelated (but still normatively unusual) partners, but not reactions to imagined sex with related partners (this effect was limited to women); also, men reacted less negatively than women to imagined sex with unrelated partners, but men and women reacted equally negatively to imagined sex with related partners (the latter effect was limited to sociosexually restricted men).  相似文献

The present study addressed the following questions: (a) To what extent do different methods of measuring the family environment converge onto a single latent construct? (b) How are the constructs of positive and of negative family environment related? (c) Do the associations among various methods of measuring the family environment differ as a function of children's gender or of risk? and (d) How are the latent constructs of family environment related to depression in mothers and their children? Participants were 240 children (mean age = 11.86 years, SD = 0.57) and their mothers, who varied with regard to their history of depression. Family environment was measured with self-report questionnaires completed separately by mothers and by children, observations of mother-child interactions, and a 5-min speech sample of each mother talking about her child. Confirmatory factor analyses revealed that different methods for assessment of the family environment converged and that the constructs of positive and of negative family environments were significantly related to each other and to depression in both mothers and their children. These findings may help inform future intervention efforts by highlighting specific parenting dimensions that are strongly associated with maternal and with child depression.  相似文献

  • Rotation, one type of visual simulation used to create three‐dimensional (3‐D) experiences, and currently being used for product presentation on some e‐tail websites, may create consumer responses. Therefore, the purpose of this study is to examine the effects of rotation in product presentation on the cognitive, affective, and conative responses of consumers. This study employed a single‐factor between‐subjects design: product presentation (rotating vs. non‐rotating). Causal model analysis showed the influence of rotation in product presentation on perceived information quantity, mood, attitude, and purchase intention. Theoretical and managerial implications, as well as future research directions, are discussed.

A central issue in cognitive neuroscience of aging research is pinpointing precise neural mechanisms that determine cognitive outcome in late adulthood as well as identifying early markers of less successful cognitive aging. One promising biomarker is beta amyloid (Aβ) deposition. Several new radiotracers have been developed that bind to fibrillar Aβ providing sensitive estimates of amyloid deposition in various brain regions. Aβ imaging has been primarily used to study patients with Alzheimer’s Disease (AD) and individuals with Mild Cognitive Impairment (MCI); however, there is now building data on Aβ deposition in healthy controls that suggest at least 20% and perhaps as much as a third of healthy older adults show significant deposition. Considerable evidence suggests amyloid deposition precedes declines in cognition and may be the initiator in a cascade of events that indirectly leads to age-related cognitive decline. We review studies of Aβ deposition imaging in AD, MCI, and normal adults, its cognitive consequences, and the role of genetic risk and cognitive reserve.  相似文献
