This study addresses self-categorization theory's contention that stereotype content varies as a function of the comparative context within which a given group is considered. A sample of 5-, 7- and 10-year-old children (n = 192) made judgments about gender ingroup behavior in one of two comparative contexts: either adults of the same sex as self or children of the opposite sex. Specifically, judgments were either of the perceived stereotypicality or central tendency of 12 types of behavior. Both types of judgment were found to differ as a function of comparative context in ways predicted by self-categorization theory. However, contrary to prediction, there was no effect of age on the extent of stereotype variability. 相似文献

Nelson Goodman and, following him, Catherine Z. Elgin and Keith Lehrer have claimed that sometimes a sample is a symbol that stands for the property it is a sample of. The relation between the sample and the property it stands for is called ‘exemplification’ (Goodman, Elgin) or ‘exemplarisation’ (Lehrer). Goodman and Lehrer argue that the notion of exemplification sheds light on central problems in aesthetics and the philosophy of mind. However, while there seems to be a phenomenon to be captured, Goodman's account of exemplification has several flaws. In this paper I will offer an alternative account of exemplification that is inspired by Grice's idea that one can communicate something by providing one's audience with intention‐independent evidence and letting them draw the obvious conclusion for themselves. This explication of exemplification will solve the problems that arose for Goodman's theory in the spirit of his approach. 1 相似文献

The past hypothesis is that the entropy of the universe was very low in the distant past. It is put forward to explain the
entropic arrow of time but it has been suggested (e.g. [Penrose, R. (1989a). The emperor’s new mind. London:Vintage Books; Penrose, R. (1989b). Annals of the New York Academy of Sciences, 571, 249–264; Price, H. (1995). In S. F. Savitt (Ed.), Times’s arrows today. Cambridge: Cambridge University Press; Price, H. (1996). Time’s arrow and Archimedes’ point. Oxford: Oxford University Press; Price, H. (2004). In C. Hitchcock (Ed.), Contemporary debates in philosophy of science. Oxford: Blackwell]) that it is itself in need of explanation. It has also been suggested that cosmic inflation could provide
the explanation, but Price (2004) raises a serious objection to this suggestion, which has otherwise received very little
attention in the philosophical literature. Price points out that the standard inflationary explanation involves a double standard:
although the evolution of the universe described by the inflationary model seems natural from the standard temporal perspective
it looks highly unnatural from the reversed temporal perspective. The main purpose of this paper is to propose a novel form
of the inflationary explanation that avoids this objection. It is argued that the inflationary model would not involve a double
standard (but would still explain the past hypothesis) if we construct the model with a global “boundary” condition instead
of a conventional boundary condition: if we assume that the universe is as generic as possible overall, rather than as generic
as possible at some given point (e.g. the Big Bang) as is assumed in the standard inflationary model. This novel form of the
inflationary explanation is then compared with Price’s 1996 preferred explanation, a version of the so-called “Weyl hypothesis”. 相似文献

The approach that philosophers have taken to history has too often been one-dimensional. It is my aim in this paper to map
out a future multi-dimensional philosophy of history, by invoking the notion of a relation with the past, and by arguing for
the philosophical relevance of multiple such relations.

The purpose of this study was to identify potential opportunities for improving member participation in community-based coalitions. We hypothesized that opportunities for influence and process competence would each foster higher levels of individual member participation. We tested these hypotheses in a sample of 818 members within 79 youth-oriented coalitions. Opportunities for influence were measured as members' perceptions of an inclusive board leadership style and members' reported committee roles. Coalition process competence was measured through member perceptions of strategic board directedness and meeting effectiveness. Members reported three types of participation within meetings as well as how much time they devoted to coalition business beyond meetings. Generalized linear models accommodated clustering of individuals within coalitions. Opportunities for influence were associated with individuals' participation both within and beyond meetings. Coalition process competence was not associated with participation. These results suggest that leadership inclusivity rather than process competence may best facilitate member participation. 相似文献

Response Style Differences in the Inattentive and Combined Subtypes of Attention-Deficit/Hyperactivity Disorder 总被引:1,自引:0,他引:1

This study examined potential differences between the inattentive and combined ADHD subtypes using laboratory tasks assessing behavioral inhibitory processes. Seventy-five children completed two tasks of behavioral inhibition believed to isolate different processes: the cued reaction time task (CRT), a basic inhibition task, and the go/no-go task (GNG), a complex inhibition task that incorporates motivational contingencies. Three groups of participants were identified, including ADHD/Inattentive (n = 17), ADHD/Combined (n = 37), and comparison (n = 21). Results indicated that rather than showing behavioral inhibition deficits, the ADHD/I children appeared overly inhibited, as evidenced by slower reaction times across the two tasks and significantly higher errors of omission in the GNG task. Additionally, the ADHD/I children did not demonstrate cue dependency effects on the CRT task, suggesting that they were failing to incorporate relevant information before making a response. The sluggish and inhibited performance of the ADHD/I group challenges the idea that it is a subtype of ADHD. 相似文献

Coordinating cognition: the costs and benefits of shared gaze during collaborative search 总被引:1,自引:0,他引:1
Collaboration has its benefits, but coordination has its costs. We explored the potential for remotely located pairs of people to collaborate during visual search, using shared gaze and speech. Pairs of searchers wearing eyetrackers jointly performed an O-in-Qs search task alone, or in one of three collaboration conditions: shared gaze (with one searcher seeing a gaze-cursor indicating where the other was looking, and vice versa), shared-voice (by speaking to each other), and shared-gaze-plus-voice (by using both gaze-cursors and speech). Although collaborating pairs performed better than solitary searchers, search in the shared gaze condition was best of all: twice as fast and efficient as solitary search. People can successfully communicate and coordinate their searching labor using shared gaze alone. Strikingly, shared gaze search was even faster than shared-gaze-plus-voice search; speaking incurred substantial coordination costs. We conclude that shared gaze affords a highly efficient method of coordinating parallel activity in a time-critical spatial task. 相似文献

Few studies to date have examined the extent to which borderline personality features are best construed as representing an underlying dimension or a discrete class or taxon. The authors conducted taxometric analyses using a large-scale sample of male (n=787) and female (n=368) prison inmates who had completed the Personality Assessment Inventory (L. C. Morey, 2007). Analyses based on the 4 subscales of the Borderline Features Scale offered compelling support for a dimensional structure in both the full sample and the female subsample--even after controlling for the potentially confounding effects of negative response distortion. Theoretical and pragmatic implications of these findings are reviewed. 相似文献
