Friend influence over alcohol intoxication and delinquent behavior was examined as a function of relative peer acceptance in a 3-year study of Swedish youth (N = 184 girls, 145 boys). Participants were in the first year of secondary school (7th grade, M = 11.7 years old) or the first year of high school (10th grade, M = 15.3 years old) at the outset. Friends resembled one another before the friendship; resemblances were even greater after the friendship began. Resemblances continued to grow among those who remained friends one year later, but declined among those whose friendships dissolved. Partners were not equally responsible for increases in similarity. In stable friendships, the more accepted partner exerted greater influence over the less accepted partner, such that the greatest increases in problem behaviors were found among less accepted youth whose friends had higher initial levels of delinquency and alcohol intoxication. Unstable friends resembled random pairs of youth in that more- and less-accepted partners were comparably uninfluential. 相似文献

The turbulence of the new economy puts demands on organizations to respond rapidly, flexibly and creatively to changing environments. Meetings are one of the organizational sites in which organizational actors “do” creativity; interaction in groups can be an important site for generating creative ideas and brainstorming. Additionally, Blount (2004) demonstrated the importance of organizational temporalities for group performance. We draw on both of these literatures and examine how temporal structures influence the climate for creativity, or the extent to which creativity is fostered, within groups. Specifically, we develop a hypothesis linking organization‐ and job‐level temporal structures to the extent to which managers structure meetings with a climate supportive of creativity. Our results demonstrate that a nuanced relationship exists between temporal structures and creative climate such that certain temporal structures appear to either enhance or decrease the creative climate of meetings. We end with a discussion of the implications of the findings for management. 相似文献

The study of religion in Western psychology has an interesting history that provides many lessons for future attempts to understand the spiritual aspects of human experience. In the past, psychologists have typically operated from one of three paradigms in their study of religion: (1) hermeneutic–phenomenological, (2) positivistic naturalism, and (3) religious integration. Each of these paradigms has a number of important theoretical assumptions and a preferred set of methodologies that offer significant advantages and disadvantages. The paradigm of positivistic naturalism, with its emphasis on quantitative questionnaire methodology, has been the most influential but also the least helpful in generating new ideas for the psychological understanding of religion, particularly as it is practiced in non-Western contexts. A historical survey of the other competing paradigms offers many insights and practical suggestions about how research in the psychology of religion might proceed in the twenty-first century. 相似文献

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

Previous research has suggested that when feature inferences have to be made about an instance whose category membership is uncertain, feature-based inductive reasoning is used to the exclusion of category-based induction. These results contrast with the observation that people can and do use category-based induction when category membership is known. The present experiments examined the conditions that drive feature-based and category-based strategies in induction under category uncertainty. Specifically, 2 experiments investigated whether reliance on feature-based inductive strategies is a product of the lack of coherence in the categories used in previous research or is due to the use of a decision-only induction procedure. Experiment 1 found that feature-based reasoning remained the preferred strategy even when categories with relatively high internal coherence were used. Experiment 2 found a shift toward category-based reasoning when participants were trained to classify category members prior to feature induction. Together, these results suggest that an appropriate conceptual representation must be formed through experience with a category before it is likely to be used as a basis for feature induction. 相似文献

Two experiments examined the impact of causal relations between features on categorization in 5- to 6-year-old children and adults. Participants learned artificial categories containing instances with causally related features and noncausal features. They then selected the most likely category member from a series of novel test pairs. Classification patterns and logistic regression were used to diagnose the presence of independent effects of causal coherence, causal status, and relational centrality. Adult classification was driven primarily by coherence when causal links were deterministic (Experiment 1) but showed additional influences of causal status when links were probabilistic (Experiment 2). Children's classification was based primarily on causal coherence in both cases. There was no effect of relational centrality in either age group. These results suggest that the generative model (Rehder, 2003a) provides a good account of causal categorization in children as well as adults. 相似文献

Whereas explicit self-esteem (ESE) refers to a conscious self-evaluation, implicit self-esteem (ISE) refers to non-conscious self-evaluation. Presumably, ISE and ESE are based on different mental processes — the experiential system and the rational system, respectively (Epstein, 1994) as well as different experiences (DeHart, Pelham, & Tennen, 2006). Two studies showed that participants who more strongly preferred positive icons and positive words showed a stronger association between ISE and ESE, presumably because they are highly willing to trust their intuitions. Because the major motive of the experiential system is the hedonic principle — pursuing positive affect and avoiding negative affect (Epstein, 2010), we argue that people's reactions to unambiguously positive stimuli should reflect their reliance on their intuition. In addition, we suggest that a better understanding of intuitiveness may yield important insights into the nature of ISE and ESE. 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
