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

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

Limited research has explored how specific elements of physical and social environments influence mental health indicators such as perceived stress, or whether such associations are moderated by gender. This study examined the relationship between selected neighborhood characteristics and perceived stress levels within a primarily low‐income, older, African‐American population in a mid‐sized city in the Southeastern U.S. Residents (n = 394; mean age=55.3 years, 70.9% female, 89.3% African American) from eight historically disadvantaged neighborhoods completed surveys measuring perceptions of neighborhood safety, social cohesion, aesthetics, and stress. Multivariate linear regression models examined the association between each of the three neighborhood characteristics and perceived stress. Greater perceived safety, improved neighborhood aesthetics, and social cohesion were significantly associated with lower perceived stress. These associations were not moderated by gender. These findings suggest that improving social attributes of neighborhoods may have positive impacts on stress and related benefits for population health. Future research should examine how neighborhood characteristics influence stress over time.  相似文献

In the present research, we followed two objectives. First, we aimed to replicate the classic finding by McAdams, Jackson, and Kirshnit (1984) that strong implicit affiliative motives predict high levels of nonverbal socializing behavior (eye contact, laughing, smiling) in dyadic interactions with an unacquainted person. Second, we applied a dual-motives perspective and hypothesized a double dissociation between implicit and explicit motives. Whereas implicit motives were supposed to predict nonverbal socializing, the corresponding explicit motives were supposed to predict verbal socializing (i.e., self-disclosure). Using observational data from 123 university students in ostensibly casual conversations, the findings by McAdams et al. were replicated, and the double-dissociation hypothesis was confirmed. These results corroborate dual-motives theory in the domain of affiliative motivation.  相似文献

Prior research on personality and politics has largely investigated relationships using national samples from North America and Europe. In contrast, we used multigroup path analysis to assess how Big Five personality, ideological attitudes (RWA, SDO), and group identities (National and Ethnic Identification) predicted right versus left Political Behavior (party support, past voting, present voting intention) across majority and minority ethnic groups in a New Zealand national sample (N = 6,333). The effects of personality on ideological attitudes and group identities were mostly invariant across ethnic groups and consistent with prior findings. In contrast, the effects of ideological attitudes on Political Behavior varied across ethnic groups being moderately strong for the European majority but nonsignificant for the minorities. Group identities had little effect on Political Behavior. We discuss cultural and contextual factors that might account for this disconnect between ideology and politics among the minority ethnic groups.  相似文献

The purpose of the present study was to investigate the coordination pattern and coordination variability (intra-subject and inter-subject) in children and adults during vertical countermovement jumps. Ten children (mean age: 11.5 ± 1.8 years) and ten adults (mean age: 26.1 ± 4.9 years) participated in the experiment. Lower body 3D-kinematics and kinetics from both legs were obtained during 9 vertical jumps of each subject. Coordination pattern and coordination variability of intra-limb and inter-limb coupling were established by modified vector coding and continuous relative phase. The adult group jumped higher and with less performance variability compared to the children. Group differences were mainly observed in the right–left foot coupling. The intra-subject coordination variability was higher in coupling of proximal segments in children compared to adults. No group differences were observed in inter-subject variability. Based on these results, it was concluded that the same movement solutions were available to both age groups, but the children were less able to consistently utilize the individually chosen coordination pattern. Thus, this ability appears to be developed through normal ontogenesis.  相似文献

We tested the hypothesis that shared emotions, notably anger, influence the formation of new self-categories. We first measured participants' (N = 89) emotional reactions to a proposal to make university assessment tougher before providing feedback about the reactions of eight other co-present individuals. This feedback always contained information about the other individuals' attitudes to the proposals (four opposed and four not opposed) and in the experimental condition emotion information (of those opposed, two were angry, two were sad). Participants self-categorised more with, and preferred to work with, angry rather than sad targets, but only when participants' own anger was high. These findings support the idea that emotions are a potent determinant of self-categorisation, even in the absence of existing, available self-categories.  相似文献

Group settings are epicentres of emotional activity. Yet, the role of emotions in groups is poorly understood. How do group-level phenomena shape group members’ emotional experience and expression? How are emotional expressions recognised, interpreted and shared in group settings? And how do such expressions influence the emotions, cognitions and behaviours of fellow group members and outside observers? To answer these and other questions, we draw on relevant theoretical perspectives (e.g., intergroup emotions theory, social appraisal theory and emotions as social information theory) and recent empirical findings regarding the role of emotions in groups. We organise our review according to two overarching themes: how groups shape emotions and how emotions shape groups. We show how novel empirical approaches break important new ground in uncovering the role of emotions in groups. Research on emotional collectives is thriving and constitutes a key to understanding the social nature of emotions.  相似文献

Individuals who show anger are rated as higher in dominance and lower in affiliation, whereas those who express sadness are rated lower in dominance and higher in affiliation. Little is known about situations where people show both expressions in sequence as happens when a first emotional reaction is followed by a second, different one. This question was examined in two studies. Overall, we found that the last emotion shown had a strong impact on perceived behavioural intentions. However, the information about the previously shown emotion was also integrated. The specific mode of integration was dependent on the salience of the change and naive theories about the type of person who changes their emotion in the face of changing events.  相似文献
