There is tension between the appealing idea that visual experience puts us in touch with objective reality and the doctrine of perceptual relativity, the claim that experience varies with such factors as distance, lighting, and angle of view. In this paper I present arguments for relativity, and then go on to propose that in view of relativity, we should believe that the properties presented to us in perception are relational and viewpoint‐dependent. I conclude by sketching a theory of how we nonetheless manage to achieve contact with objective properties. According to the theory, such contact is best explained in terms of perceptual representations acting in concert with cognitive and motoric representations, not in terms of perceptual representations alone.  相似文献

Seeking to rectify the asocial nature of conventional social psychological investigation, some researchers and scholars have sought ways to better understand what is shared in everyday thinking and have, accordingly, focused their attention on the notion of ideology. Although this vein of scholarship has reclaimed the social domain, it has not thoroughly accounted for the way that ideologies can be imposed, and as such, does not adequately address the concept in a way that honors its origin and development. In this paper, I articulate a conceptual framework that can be used to underpin research on momentary ideological impositions in relation to people's negotiation of imposed value orientations—moments that can be described as instances of ideological rupturing. After situating this articulation in relation to the work of other ideology‐focused psychologists, I introduce a recent enactment of educational policy as an illustrative case of ideological rupturing. In so doing, I present a narrative approach that is grounded in dialogic activity as an ideal way to investigate instances of ideological rupturing.  相似文献

Stereotyping plays an important role in how we perceive the members of social groups. Yet stereotyping is complicated by the fact that every individual simultaneously belongs to multiple social groups. For example, the stereotypes that are called to mind about a Black individual can vary depending on that person's age, gender, and sexual orientation. This phenomenon—termed intersectional stereotyping—has recently inspired a variety of intriguing research findings. But these research findings pose challenges for prevalent theories of stereotyping. These prevalent theories tend to argue either that (a) perceivers inevitably attend to certain social identities (e.g., gender) when stereotyping intersectional targets, or that (b) perceivers inevitably attend to all detectable social identities at once. In contrast to these perspectives, we argue that perceivers generally attend to just one social identity (or one intersection of identities) at a time when stereotyping intersectional targets, as a function of the social context. For example, gay Black men can be alternately stereotyped as gay people, as Black people, as men, or as gay Black men specifically. The approach described here can account for a diverse array of findings emerging from research on intersectional stereotyping. Moreover, by specifying the factors that render particular identities salient in the minds of social perceivers, this approach offers clear and falsifiable predictions regarding the situated stereotyping of multifaceted individuals.  相似文献

Little is known about the levels of bully/victim behaviors in schools in Northern Ireland. The aim of the present study was to supplement previous research findings from Northern Ireland by examining the self-reported experiences of school bullying among Northern Ireland children through data collected as part of the 1998 "Youth Life and Times Survey." A random sample of 397 12 to 17-year-olds living throughout Northern Ireland were interviewed during 1998 and 1999. As part of the larger survey, six questions were asked relating to experience of bullying behaviors and being a victim of such behaviors. The findings suggests that the incidence of school bullying in Northern Ireland may be higher than those found in the rest of Ireland and the United Kingdom. Furthermore, the data supplements previous findings among Northern Irish children employing alternate measures of bully/victim problems.  相似文献

The relationship between perfectionism and eating disorders is well established and is of theoretical interest. This study used an experimental design to test the hypothesis that manipulating personal standards, a central feature of perfectionism, would influence eating attitudes and behaviour. Forty-one healthy women were randomly assigned either to a high personal standards condition (n = 18) or to a low personal standards condition for 24 h (n = 23). Measures of personal standards, perfectionism, and eating attitudes and behaviour were taken before and after the experimental manipulation. The manipulation was successful. After the manipulation, participants in the high personal standards condition ate fewer high calorie foods, made more attempts to restrict the overall amount of food eaten, and had significantly more regret after eating than those in the low personal standards condition. Other variables remained unchanged. It is concluded that experimental analyses can be of value in elucidating causal connections between perfectionism and eating attitudes and behaviour.  相似文献

We investigated the effects of extinction and reinstatement on attentional bias to fear-conditioned signals in healthy individuals using an emotional modification of a spatial cueing paradigm. Spatial cues were emotionally modulated using differential conditioning. The CS+ was sometimes followed by an aversive electrocutaneous stimulus (UCS), whereas the CS- was never followed by the UCS. During a subsequent extinction phase no UCS was presented anymore. The reinstatement phase started with one or four unpredicted UCS-only trials for half of the participants (reinstatement group). For the other half there were no additional UCS presentations (control group). We found that attention was biased to threat signals during acquisition. This biased attention largely disappeared during extinction. During the reinstatement phase attentional bias to threat signals re-emerged in the reinstatement group, but not in the control group.  相似文献

Item response theory (IRT) has advantages over classical test theory in evaluating diagnostic criteria. In this study, the authors used IRT to characterize the psychometric properties of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV; American Psychiatric Association, 1994) alcohol and cannabis use disorder symptoms among 472 clinical adolescents. For both substances, DSM-IV symptoms fit a model specifying a unidimensional latent trait of problem severity. Threshold (severity) parameters did not distinguish abuse and dependence symptoms. Abuse symptoms of legal problems and hazardous use, and dependence symptoms of tolerance, unsuccessful attempts to quit, and physical-psychological problems, showed relatively poor discrimination of problem severity. There were gender differences in thresholds for hazardous use, legal problems, and physical-psychological problems. The results illustrate limitations of DSM-IV criteria for alcohol and cannabis use disorders when applied to adolescents. The development process for the fifth edition (DSM-V) should be informed by statistical models such as those used in this study.  相似文献

The authors proposed a model suggesting that organizational environments supporting high levels of informal supervisor and coworker feedback are associated with lower employee perceptions of organizational politics. Furthermore, these lowered perceptions of politics were proposed to result in higher employee morale (as reflected in job satisfaction and affective commitment) and, through morale, to higher levels of task performance and organizational citizenship. The proposed mediational model was supported with empirical results from 150 subordinate-supervisor dyads sampled across a variety of organizations. Higher quality feedback environments were associated with lower perceptions of organizational politics, and morale mediated the relationships between organizational politics and various aspects of work performance. These findings suggest that when employees have greater access to information regarding behaviors that are acceptable and desired at work, perceptions of politics are reduced and work outcomes are enhanced.  相似文献

The authors examined the differences in mean level of cognitive ability and adverse impact that can be expected when selecting employees solely on educational attainment as a proxy for cognitive ability versus selecting employees directly on cognitive ability. Selection using cognitive ability worked as a more efficient cognitive screen. Imposing an educational attainment standard of at least 1 year of college, though, did result in noticeably higher levels of cognitive ability in potential applicant pools than did random selection, meaning that educational attainment does work as a cognitive screen. These results held not only in a nationally representative sample but also within and across 6 different occupational groups. Finally, adverse impact is examined for selection using educational attainment, compared with selection on the basis of cognitive ability.  相似文献
