ObjectivesThis study tested the link between daily body-related upward social comparisons (BUSCs) and exercise behavior, and examined how appearance evaluation and gender may impact this association.MethodIn a weeklong assessment, 87 participants (54% women) completed daily retrospective measures of social comparisons and exercise behavior, and a one-time trait measure of appearance evaluation.ResultsBased on findings from hierarchical linear modeling, men with more negative appearance evaluations reported higher exercise engagement on days when they made more (compared to less) BUSCs. Meanwhile, women with more negative appearance evaluations reported less exercise engagement on days when they engaged in more (compared to less) BUSCs.ConclusionsAmong individuals who experience negative appearance evaluations, upward body comparisons are associated with more exercising among men, and lower exercise among women. BUSCs have an important role in promoting adaptive exercise behaviors and managing negative body image.  相似文献

This work aims to portray the effects of Freud’s anxiety about anti-Semitic violence on his political theory and metapsychology. Taking as its entry point Freud’s reorientation of anti-Semitism as aggressive action, I argue that Freud’s fear of the violent mob can be located in three interconnected dimensions of his work, all deeply informed by Hobbesian imagination. First, Freud accepted a Hobbesian vision of social antagonism into his political theory; second, he formulated a deeper, more efficient defence mechanism against mob violence with his notion of psychical guilt; third, Freud’s fears penetrated his metapsychology. Suffering from anti-Semitism, Freud was not only quick to accept a Hobbesian perspective – he also reconstructed it to a degree that radically changed its meaning. Freud’s third and most pervasive manoeuvre destabilized one of Hobbes’s fundamental theoretical tenets by suggesting that the Hobbesian State of Nature is inherently a non-human reality.  相似文献

ObjectivesGrounded in Self-Determination Theory, this study examined whether physical education (PE) teachers' psychological need satisfaction experienced during continuous professional development (CPD) on need-supportive teaching predicted changes in their effectiveness and feasibility beliefs regarding the proposed teaching approach, as well as their intentions to apply this approach and subsequent changes in their self-reported in-class behaviors.MethodsPrior to the training, a sample of 80 PE teachers (57.5% men, Mage = 42.70 ± 10.15 years) reported on their effectiveness and feasibility beliefs regarding autonomy-supportive and structuring teaching strategies and their in-class application of these strategies. Immediately following the training, these beliefs were assessed again and participants reported on their psychological need satisfaction experienced during the training and their intentions to apply the proposed strategies. Finally, two weeks after the training, participants' self-reported in-class application of the teaching strategies was measured for the second time.ResultsPsychological need satisfaction experienced during the training related to a change in effectiveness and feasibility beliefs regarding autonomy support and structure, and to teachers' intentions to apply the proposed strategies as reported immediately after receiving the training. In addition, teachers' intentions related to a change in their self-reported in-class application of structuring, but not autonomy-supportive, teaching strategies.ConclusionsExperiences of psychological need satisfaction during CPD can help to increase the likelihood that teachers become more convinced about the effectiveness and feasibility of the proposed change and can produce greater intentions toward change, which may relate to actual (albeit) self-reported behavior change.  相似文献

ObjectivesThis study examined how autonomy support from parents and autonomy support from coaches are associated with sport-related outcomes of adolescent-athletes. Two alternative hypotheses were proposed: (a) a synergistic socialization interaction in which high levels of autonomy support provided by parents and coaches are both needed to obtain the most positive sport-related outcomes, (b) a compensatory-protective interaction in which coaching autonomy support is more important for sport-related outcomes in athletes perceiving lower levels of parental autonomy support.DesignTwo studies using prospective designs.MethodStudy 1 was conducted with adolescent soccer players (N = 46) and Study 2 was conducted with gymnasts (N = 85). In both studies, athletes reported the extent to which they perceived their parents and coaches provided autonomy support. Athletes also completed scales assessing their motivation toward sport (Studies 1 and 2), situational motivation prior to and following a competition (Study 2), and need satisfaction (Study 1). Sport achievement and performance were also assessed in the form of goal attainment (Study 1), self-reported achievement following the competition (Study 2), and flow states (Study 2). Hierarchical moderated regressions were conducted in order to test our competing hypotheses.ResultsAnalyses provided support for the compensatory-protective interaction hypothesis. Coaching autonomy support was more strongly related to sport motivation, need satisfaction, sport achievement, and flow in athletes who perceived lower level of parental autonomy support.ConclusionsThis research program provided support for the study of the interactive effect of perceived autonomy support from distinct socialization agents (i.e., parents and coaches) and its impact on adolescent-athletes.  相似文献

ObjectivesTo report the theory-based process evaluation of the Bristol Girls' Dance Project, a cluster-randomised controlled trial to increase adolescent girls' physical activity.DesignA mixed-method process evaluation of the intervention's self-determination theory components comprising lesson observations, post-intervention interviews and focus groups.MethodFour intervention dance lessons per dance instructor were observed, audio recorded and rated to estimate the use of need-supportive teaching strategies. Intervention participants (n = 281) reported their dance instructors' provision of autonomy-support. Semi-structured interviews with the dance instructors (n = 10) explored fidelity to the theory and focus groups were conducted with participants (n = 59) in each school to explore their receipt of the intervention and views on the dance instructors' motivating style.ResultsAlthough instructors accepted the theory-based approach, intervention fidelity was variable. Relatedness support was the most commonly observed need-supportive teaching behaviour, provision of structure was moderate and autonomy-support was comparatively low. The qualitative findings identified how instructors supported competence and developed trusting relationships with participants. Fidelity was challenged where autonomy provision was limited to option choices rather than input into the pace or direction of lessons and where controlling teaching styles were adopted, often to manage disruptive behaviour.ConclusionThe successes and challenges to achieving theoretical fidelity in the Bristol Girls' Dance Project may help explain the intervention effects and can more broadly inform the design of theory-based complex interventions aimed at increasing young people's physical activity in after-school settings.  相似文献

Individuals adopt self-presentation motives in sport settings to shape others’ perceptions of the self. However, the effectiveness of different types of motives in shaping favourable evaluations has not been explored. We examined pathways from 2 × 2 self-presentation motives to others’ evaluative perceptions via task behaviour. Participants (N = 112) reported their self-presentation motives immediately prior to a basketball game, had their behaviours (i.e., shots, time spent on the sideline) recorded via video during the game, then completed agentic (e.g., competent) and communal (e.g., supportive) ratings of their teammates following the game. Structural equation modeling revealed positive pathways from acquisitive motives to behaviour (i.e., acquisitive agency) and favourable evaluations (i.e., acquisitive-agency and -communion). Negative pathways were observed from protective communion to behaviour and others’ evaluations. The findings indicate that different types of self-presentation motives may differ in their impression management effectiveness and may either promote or suppress task behaviour.  相似文献

Previous research indicates that children hold negative beliefs about peers with foreign accents, physical disabilities, and people who are obese. The current study examined skills associated with individual differences in children's social judgements about these typically stereotyped groups. Theory of mind, memory, and cognitive inhibition were assessed in 3‐ to 6‐year‐olds. Then, children were asked to make trait attributions and behavioural predictions about story characters' willingness to help a peer. Results indicated that better theory of mind skills were related to greater positive trait attributions and behavioural predictions about typically stereotyped characters. Younger children made fewer positive behavioural predictions as compared to older children, but both age groups made positive trait attributions. Overall, memory and inhibition had little to no influence on children's responses, although the results varied by story type. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Research has shown that self‐efficacy is often one of the most important personal resources in the work context. However, because this research has focused on cognitive and task‐oriented self‐efficacy, little is known about social and emotional dimensions of self‐efficacy at work. The main aim of the present study was to investigate social and emotional self‐efficacy dimensions at work and to compare them to a cognitive and task‐oriented dimension. Scales to measure social and emotional self‐efficacy at work were developed and validated and found to be well differentiated from the cognitive task‐oriented occupational self‐efficacy scale. Confirmatory factor analyses of data from 226 Swedish and 591 German employees resulted in four separate but correlated self‐efficacy dimensions: (1) occupational; (2) social; (3) self‐oriented emotional; and (4) other‐oriented emotional. Social self‐efficacy explained additional variance in team climate and emotional self‐efficacy in emotional irritation and emotional exhaustion, over and above effects of occupational self‐efficacy. Men reported higher occupational self‐efficacy, whereas social and emotional self‐efficacy revealed no clear gender differences. The scales have strong psychometric properties in both Swedish and German language versions. The positive association between social self‐efficacy and team climate, and the negative relationships between self‐oriented emotional self‐efficacy and emotional irritation and emotional exhaustion may provide promising tools for practical applications in work settings such as team‐building, staff development, recruitment or other training programs aiming for work place health promotion. The next step will be to study how social and emotional self‐efficacy relate to leadership, well‐being and health over time.  相似文献

We examine the (in)compatibility of diversity and sense of community by means of agent‐based models based on the well‐known Schelling model of residential segregation and Axelrod model of cultural dissemination. We find that diversity and highly clustered social networks, on the assumptions of social tie formation based on spatial proximity and homophily, are incompatible when agent features are immutable, and this holds even for multiple independent features. We include both mutable and immutable features into a model that integrates Schelling and Axelrod models, and we find that even for multiple independent features, diversity and highly clustered social networks can be incompatible on the assumptions of social tie formation based on spatial proximity and homophily. However, this incompatibility breaks down when cultural diversity can be sufficiently large, at which point diversity and clustering need not be negatively correlated. This implies that segregation based on immutable characteristics such as race can possibly be overcome by sufficient similarity on mutable characteristics based on culture, which are subject to a process of social influence, provided a sufficiently large “scope of cultural possibilities” exists.  相似文献
