Adolescents tend to categorize themselves and their peers into discrete ingroups and outgroups. A comparison of ingroup versus outgroup perceptions of the characteristics of high-risk youth was investigated. Based on current stereotype research, we examined the perspective that outgroup members would hold a more extreme stereotype of high-risk youth compared to the perceptions of ingroup members. A total of 955 7th- and 10th-grade southern California adolescents completed a questionnaire regarding the characteristics of their own peer group and a high-risk group. Support was obtained for an extremity of judgement effect. Outgroup youth perceived that their high-risk peers engaged in fewer school and nonschool low-risk activities, more high-risk activities, and greater drug use than did ingroup members. Outgroup members also held perceptions of high-risk youth as less likely to hold a white-collar job than did the ingroup members. The perceptions that adolescents have of these groups may play major roles in their own social behavior. The implications of these results for future tobacco use prevention programs are considered. 相似文献

Our longitudinal study contributes to the body of literature on depression in childhood by examining potential protective factors. We investigated the influence of maternal depressive symptoms on child depressive symptoms at early school age and its gender-specific moderation by children’s narrative representations of the maternal figure, over and above children’s own depressive symptoms at preschool age. Children’s narrative representations were assessed using the MacArthur Story Stem Battery in 170 preschool children (92 girls; 54.1?%) oversampled for internalizing symptoms. Children’s depressive symptoms were assessed at preschool age (Time 1; 4–6 years) and at early school age (Time 2; 6–8 years) by maternal report; mothers’ depressive symptoms were assessed at Time 1. The results showed that for boys, only their own depressive symptoms at Time 1 predicted their depressive symptoms at Time 2. For girls, maternal depressive symptoms were a significant risk factor for their own depressive symptoms at Time 2. Regarding this association, we also found a moderation effect: girls with more positive narrative representations of the maternal figure showed a reduced negative impact of maternal depressive symptoms on their own depressive symptoms at Time 2. This implies that clinical practice should screen a child for early depressive symptoms, especially if the mother displays depressive symptoms. Clinicians might also assess children’s inner working models, which can serve as a protective factor. 相似文献

ABSTRACT Why do people feel compassion? Two largely separate research literatures – one driven by evolutionary psychology and one driven by attribution theory – have shown that feelings of compassion for needy individuals and subsequent helping are predicted by both genetic relatedness and causal control. Research also suggests that emotional closeness, rather than compassion, motivates help for family. In two studies, we tested the role of genetic relatedness and control on cognitive and emotional mediators of helping. Results revealed that relatedness and control had distinct and independent effects on willingness to help needy individuals that were mediated by emotional closeness and compassion, respectively. These results provide a unique bridging of disparate literatures and suggest that emotional closeness and compassion serve distinct functions in facilitating prosocial behavior. 相似文献

Researchers have suggested that bystander behaviors and victim coping play an important role in counteracting the negative effects of bullying. The current study investigated the relationship between students’ ratings of coping effectiveness when addressing bullying and their behaviors as bystanders when witnessing bullying. Surveys were administered in a Midwestern, suburban school district. Some associations between perceptions of coping effectiveness and bystander behavior supported our hypotheses (e.g., constructive coping associated with defending bystander behaviors, externalizing associated with pro-bullying behaviors). However, some findings did not support hypothesized relationships. For example, higher ratings of effectiveness for cognitive distancing as a coping strategy were associated with increased defending behaviors as a bystander. Gender moderated some of these relationships. Pro-bullying bystander behavior was associated with increased ratings of cognitive distancing and decreased reports of constructive coping effectiveness for girls. Implications for future research and practice are discussed. 相似文献

Several studies have examined the efficacy of behavior analytic coaching strategies in sports to increase performance fluency. Rock climbing is a multifaceted sport requiring mastery of several complex behavior chains in order to successfully navigate climbing surfaces. To date, most investigations have focused on the physiological aspects of rock climbing, as opposed to training specific rock-climbing movements. In this replication and extension, researchers used a multiple baseline design across skills to examine an expert video modeling plus video and verbal feedback training package on foundational rock-climbing skills of novice adult climbers. Results demonstrated that all participants showed an increase in accurate performance for all three skills that were targeted in the intervention. 相似文献

The La Bella Figura concept extends to many Italian cultural dimensions including physical appearance, perception of self, and behaviours. La Bella Figura plays an essential role in shaping Italian consumer behaviour and consumerism. The current study sought to understand how women living in Italy conceptualize La Bella Figura and how it affects their day‐to‐day lives, attitudes, and consumption behaviours. This research extracted concepts from Consumer Culture Theory to construct a qualitative codebook and structure thematic data analyses. Semi‐structured interviews were conducted with 30 women aged 18–50 years living in Florence, Italy. Participants were recruited through study flyers, social media, and snowball sampling. Open and axial coding were facilitated by HyperRESEARCH 4.0.1 software to generate key themes. Data were collected and analyzed by trained researchers living in Florence, Italy, who utilized grounded theory techniques to identify emergent themes. Results indicated various components of La Bella Figura contributed to consumer behaviour, namely its influence on identity (i.e., appearance, confidence), lifestyle goals (i.e., health, consumerism), and social norms (i.e., perceptions of others, media). Findings offer practical recommendations for marketers and retailers to appeal to the Italian market through effective and informed mediums. 相似文献
