As social media use becomes increasingly widespread among adolescents, research in this area has accumulated rapidly. Researchers have shown a growing interest in the impact of social media on adolescents’ peer experiences, including the ways that the social media context shapes a variety of peer relations constructs. This paper represents Part 2 of a two-part theoretical review. In this review, we offer a new model for understanding the transformative role of social media in adolescents’ peer experiences, with the goal of stimulating future empirical work that is grounded in theory. The transformation framework suggests that the features of the social media context transform adolescents’ peer experiences by changing their frequency or immediacy, amplifying demands, altering their qualitative nature, and/or offering new opportunities for compensatory or novel behaviors. In the current paper, we consider the ways that social media may transform peer relations constructs that often occur at the group level. Our review focuses on three key constructs: peer victimization, peer status, and peer influence. We selectively review and highlight existing evidence for the transformation of these domains through social media. In addition, we discuss methodological considerations and key conceptual principles for future work. The current framework offers a new theoretical perspective through which peer relations researchers may consider adolescent social media use.  相似文献

Drawing on social comparison and equity theories, we investigated the role that perceived similarity of a comparison target plays in how resentful people feel about their relative financial status. In Study 1, participants tended to choose a comparison target who was better off, and they selected a target they perceived to be more similar than dissimilar along dimensions that surrounded their financial outcomes. In Study 1, perceived relative disadvantage was positively associated with resentment regardless of the perceived similarity of the comparison target. The results of Studies 2 to 5b clarified these findings by showing that being both similar and dissimilar to a target can cause resentment depending on the context. Using hypothetical and real social comparisons, we found that people are more dissatisfied with their financial outcomes when their comparative targets have the same background qualifications (i.e., are similar) but are financially better off (Studies 2, 3b, 4, and 5b). However, we also found that when the comparative financial contexts were similar (i.e., equal affluence), participants were more dissatisfied when their target for comparison had lower qualifications (i.e., was dissimilar; Studies 2, 3a, 4, and 5a). In all cases, perceptions of unfairness mediated the effects of social comparison on financial dissatisfaction. Taken together, these studies address some of the ambiguities around what it means to be similar to a target in the context of social comparisons of affluence, and they underscore the importance of perceived unfairness in the link between social comparison and resentment with one's financial status.  相似文献

Using the perspective of instructional conversation, we investigated how one teacher regulated student participation and conceptual reasoning in the middle-school mathematics classroom. We examined the elicitations—questions and provocative statements—made by the teacher over a four-day algebra lesson. Analyses showed how the teacher systematically regulated the level of cognitive complexity of his elicitations in reaction to students' responses. When students gave inaccurate or incomplete answers, the teacher tended to reduce the level of cognitive complexity needed to respond to a subsequent elicitation, with the apparent impact being that he scaffolded participation and reasoning. When students provided responses that were mathematically accurate, the teacher usually increased the elicitation level, which subsequently engaged students in more sophisticated forms of reasoning.  相似文献

The Power of Food Scale (PFS) was developed to assess hedonic hunger, or how individuals think and feel about food and eating in the absence of metabolic need. The measure was originally developed and validated in two adult samples, and recent preliminary support has been provided for the validity in a sample of preadolescents. The aim of the current study was to conduct a confirmatory factor analysis (CFA) on the PFS in a community sample of preadolescents and adolescents to examine the psychometric properties in youth. Participants were 148 youth ages 11–18 (M = 12.85) from two Midwestern communities in the United States. Participants completed the PFS to assess for hedonic hunger. Structural equation modeling was used to conduct multiple CFAs to test varying factor structures of the PFS in preadolescents and adolescents. Results suggested that the scale was best represented by the previously established 15-item version of the measure with an aggregate domain and three subscales based on food proximity (i.e., food available, food present, and food tasted). Results from the CFA revealed that the measurement model had a close fit (RMSEA = 0.033, CFI = 0.985). Cronbach’s α for the total scale and the three subscales ranged from 0.86 to 0.95. Findings suggest that the previously established factor structure of the 15-item PFS best represents the factor structure of the measure in a community sample of preadolescents and adolescents.  相似文献

In a first stage of training, participants learned to associate four visual cues (two different colors and two different shapes) with verbal labels. For Group S, one label was applied to both colors and another to both shapes; for Group D, one label was applied to one color and one shape, and the other label to the other cues. When subsequently required to learn a task in which a given motor response was required to one of the colors and one of the shapes, and a different response to the other color and the other shape, Group D learned more readily than Group S. The task was designed so that the associations formed during the first stage of training could not generate differential transfer to the second stage. The results are consistent, however, with the proposal that training in which similar cues are followed by different outcomes will engage a learning process that boosts the attention paid to features that distinguish these cues.  相似文献

Everyday conversations among non‐Indigenous Australians are a significant site in which racism towards Indigenous Australians is reproduced and maintained. This study explores the possibilities of everyday antiracism by asking how people negotiate racist discourses in interpersonal contexts. Twelve first year psychology students (10 female, 2 male, aged 18–50) who had completed a compulsory Indigenous studies course were recruited as participants. Semi‐structured interviews were thematically analysed for the constraints and facilitators for responding to racism in everyday contexts. As constraints against speaking up, participants offered ‘social expectations to fit in’, ‘fear of provoking aggression and conflict’, assessments of ‘the type of relationship’, whether they ‘could make a difference’ and the ‘type of racism’. As a facilitator for speaking up, participants reported they were confident in challenging erroneous statements when they felt well informed and authoritative about the facts. The research suggests that everyday antiracism requires a preparedness to deal with possible discomfort and ‘bad feeling’ which participants reported avoiding. The paper concludes with suggestions for stimulating critical thinking and intergroup dialogue in relation to everyday antiracism. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

We report four investigations in which 5 to 7 year olds judged whether or not they knew familiar- and unfamiliar-named targets. Under some conditions judgments were made in relation to performance on a relevant task, e.g., children judged whether they knew the picture they had picked from a set was the target. Under other conditions, children judged their state of knowledge not in relation to performance, e.g., they answered "Do you know who (target) is?" Under both types of condition, children nearly always made correct "know" judgments when targets were familiar. Correct "don't know" judgments about unfamiliar targets were relatively common when judgments were not made in relation to performance on a task (average scores 80-90% correct), but were less frequent when knowledge was judged in relation to performance on a task (average scores 40-70% correct). Knowledge judged in relation to performance was overestimated even when children did not choose the picture they thought might be the target before making their judgment, when the pictures were face-down, and when children predicted performance on a task not yet present. It seems that although children can make relatively accurate judgments of their own knowledge states, they tend to overestimate their competence when assessing their knowledge in relation to performance on a task. We discuss why this might be.  相似文献

Four experiments examined the role of selective attention in a new causal judgment task that allowed measurement of both causal strength and cue recognition. In Experiments 1 and 2, blocking was observed; pretraining with 1 cue (A) resulted in reduced learning about a 2nd cue (B) when those 2 cues were trained in compound (AB+). Participants also demonstrated decreased recognition performance for the causally redundant Cue B, suggesting that less attention had been paid to it in training. This is consistent with the idea that attention is preferentially allocated toward the more predictive Cue A, and away from the less predictive Cue B (e.g., N. J. Mackintosh, 1975). Contrary to this hypothesis, in Experiments 3 and 4, participants demonstrated poorer recognition for the most predictive cues, relative to control cues. A new model, which is based on N. J. Mackintosh's (1975) model, is proposed to account for the observed relationship between the extent to which each cue is attended to, learned about, and later recognized  相似文献

We extend recent conceptual work on withdrawal states and develop a framework to examine behavioral tendencies of reluctant stayers (i.e., employees who desire to leave but cannot). Although principles of self-interest suggest that these employees ought to behave appropriately to maintain employment, reactance theory suggests that the combination of high turnover intentions and low job alternatives may result in lower performance and greater deviance. Contrary to conventional wisdom but consistent with reactance theory, low perceived job alternatives strengthened the positive relationship between turnover intentions and deviance, as well as the negative relation between intentions to quit and task performance. Moderated-mediation analyses revealed that the indirect effect of work frustration (via turnover intentions) was stronger on task performance and deviance when perceived job alternatives were low rather than high.  相似文献
