The current work examined contributions of emotion-resembling facial cues to impression formation. There exist common facial cues that make people look emotional, male or female, and from which we derive personality inferences. We first conducted a Pilot Study to assess these effects. We found that neutral female versus neutral male faces were rated as more submissive, affiliative, na?ve, honest, cooperative, babyish, fearful, happy, and less angry than neutral male faces. In our Primary Study, we then "warped" these same neutral faces over their corresponding anger and fear displays so the resultant facial appearance cues now structurally resembled emotion while retaining a neutral visage (e.g., no wrinkles, furrows, creases, etc.). The gender effects found in the Pilot Study were replicated in the Primary Study, suggesting clear stereotype-driven impressions. Critically, ratings of the neutral-over-fear warps versus neutral-over-anger warps also revealed a profile similar to the gender-based ratings, revealing perceptually driven impressions directly attributable to emotion overgeneralisation.  相似文献

Impairment on standard tests of delayed recall is often already maximal in the aMCI stage of Alzheimer's Disease. Neuropathological work shows that the neural substrates of memory function continue to deteriorate throughout the progression of the disease, hinting that further changes in memory performance could be tracked by a more sensitive test of delayed recall. Recent work shows that retention in aMCI patients can be raised well above floor when the delay period is devoid of further material - 'Minimal Interference'. This memory enhancement is thought to be the result of improved memory consolidation. Here we used the minimal interference/interference paradigm (word list retention following 10 min of quiet resting vs. picture naming) in a group of 17 AD patients, 25 aMCI patients and 25 controls. We found (1) that retention can be improved significantly by minimal interference in patients with aMCI and patients with mild to moderate AD; (2) that the minimal interference paradigm is sensitive to decline in memory function with disease severity, even when performance on standard tests has reached floor; and (3) that this paradigm can differentiate well (80% sensitivity and 100% specificity) between aMCI patients who progress and do not progress to AD within 2 years. Our findings support the notion that the early memory dysfunction in AD is associated with an increased susceptibility to memory interference and are suggestive of a gradual decline in consolidation capacity with disease progression.  相似文献

This paper reports key findings from a content analysis of gender and ethnic depictions in a sample of 2,120 New Zealand prime-time television advertisements screened in 2006. The study explored the following questions: With what product categories are male and female White, Māori/Pasifika and Asian characters most commonly associated? What are the most common occupational roles of male and female White, Māori/Pasifika and Asian characters? The results reveal highly stereotypical depictions of women and men within each ethnic category. White men dominated advertisements for foodstuffs, telecommunications and financial/corporate/legal services and were over-represented as professionals/white collar workers, while White women were over-represented in advertisements for household products, personal products, and medical products and featured predominantly as homemakers. Māori/Pasifika men were over-represented as athletes and service and sales workers. Non-White women featured prominently within multi-ethnic groups in advertisements for personal grooming products and most frequently featured as glamour models, while non-White men were over-represented as blue collar workers. Largely absent were Māori/Pasifika women and Asians of both genders, potentially exacerbating the multiple axes of subordination encountered by these groups in the New Zealand context.  相似文献

There are three distinct questions associated with Simpson’s paradox. (i) Why or in what sense is Simpson’s paradox a paradox? (ii) What is the proper analysis of the paradox? (iii) How one should proceed when confronted with a typical case of the paradox? We propose a “formal” answer to the first two questions which, among other things, includes deductive proofs for important theorems regarding Simpson’s paradox. Our account contrasts sharply with Pearl’s causal (and questionable) account of the first two questions. We argue that the “how to proceed question?” does not have a unique response, and that it depends on the context of the problem. We evaluate an objection to our account by comparing ours with Blyth’s account of the paradox. Our research on the paradox suggests that the “how to proceed question” needs to be divorced from what makes Simpson’s paradox “paradoxical.”  相似文献

Various studies have found that viewing physical or relational aggression in the media can impact subsequent engagement in aggressive behavior. However, this has rarely been examined in the context of relationships. Accordingly, the aim of this study was to examine the connection between viewing various types of aggression in the media and perpetration of aggression against a romantic partner. A total of 369 young adults completed a variety of questionnaires asking for their perpetration of various forms of relationship aggression. Participants' exposure to both physical and relational aggression in the media was also assessed. As a whole, we found a relationship between viewing aggression in the media and perpetration of aggression; however, this depended on the sex of the participant and the type of aggression measured. Specifically, exposure to physical violence in the media was related to engagement in physical aggression against their partner only for men. However, exposure to relational aggression in the media was related to romantic relational aggression for both men and women.  相似文献

The authors investigated the relationship between religious and spiritual values and moral commitment in marriage to further inform marriage and family counselors about the nature of committed relationships. Using a qualitative research design, they examined individuals' perceptions of moral commitment in their marriage and how their religious and spiritual values influence those perceptions. Narrative text was analyzed through an iterative process, involving constant comparison of emerging themes, and 6 categories materialized. Findings build on existing knowledge regarding the importance of moral commitment to marital health specifically as it relates to the counseling profession.  相似文献

The study examined the responses of typically developing infants to the distress of another, prior to and following the transition to the second year. Infants’ responses to maternal simulations of distress and to a peer distress videotape were observed from 8 to 16 months, using an accelerated longitudinal design (overall n = 37). Modest levels of affective and cognitive empathy for another in distress were already evident before the second year, and increased gradually (and not always significantly) across the transition to the second year. Prosocial behavior was rare in the first year and increased substantially during the second year. Self-distress reactions were rare overall. Individual differences in cognitive and affective empathy assessed in the first year, particularly at 10-months, predicted the levels of prosocial behavior observed in the second year. No gender differences were found. Theoretical implications and future research directions are discussed.  相似文献

Nurses working for telephone‐based medical helplines must maintain attentional focus while quickly and accurately processing information given by callers to make safe and appropriate treatment decisions. In this study, both higher levels of general occupational stress and elevated stress levels on particular shifts were associated with more frequent failures of attention, memory, and concentration in telephone nurses. Exposure to a stressful shift was also associated with a measurable increase in objectively assessed information‐processing errors. Nurses who experienced more frequent cognitive failures at work made more conservative decisions, tending to refer patients on to other health professionals more often than other nurses. As stress is associated with cognitive performance decrements in telephone nursing, stress‐reduction interventions could improve the quality and safety of care that callers to medical helplines receive.  相似文献

We conducted two experiments to test the impact of positive affect on social problem solving. In Experiment 1, participants induced to experience a positive (vs. neutral) affective state generated a greater number of relevant steps to solve fictitious interpersonal problems as well as more effective solutions to the problems. In Experiment 2, participants induced to experience a positive (vs. negative) affective state generated more functional solutions to their own social problems. The positive mood effects observed in Experiment 2 were moderated by dispositional optimism. Our findings have practical implications, as the extent to which individuals are able to generate effective solutions to social problems has far‐reaching consequences with respect to personal adjustment and social functioning.  相似文献
