An extended theory of planned behavior ( Ajzen, 1991 ), incorporating the post‐decisional phase of behavior and constructs from self‐determination theory ( Deci & Ryan, 1985 ), was tested for physical activity using a prospective survey design. Participants (N = 172) completed measures of intentions, attitudes, subjective norms, perceived behavioral control (PBC), self‐determined motivation, continuation intentions, and chronically accessible physical activity motives. Participants completed a self‐report measure of physical activity 3 weeks later. Path analysis supported the predictive utility of the proposed model. Importantly, the effect of continuation intentions of success on physical activity behavior was moderated by chronically accessible physical activity motives. Findings underscore the importance of taking into account continuation intentions, self‐determined motivation, and individuals' chronically accessible motives when developing physical‐activity‐promoting interventions. 相似文献

Background. Girls are considerably less interested in scientific subjects than boys. One reason may be that scientific subjects are considered to be genuinely masculine. Thus, being interested in science may threaten the self‐perception of girls as well as the femininity of their self‐image. Aims. If scientific topics that are considered to be stereotypically feminine were chosen, however, this potential threat might be overcome which, in turn, might lead to an increase in girls’ interest in science. This hypothesis was empirically tested by means of two studies. Sample. Participants were 294 (Study 1) and 190 (Study 2) Grade 8 to Grade 9 students. Method. Gender differences in students’ interest in masculine and feminine topics were investigated for a range of scientific concepts (Study 1) as well as for a given scientific concept (Study 2) for four scientific subjects (i.e., biology, physics, information technology, and statistics), respectively. Results. Both studies indicated that the mean level of girls’ scientific interest was higher when scientific concepts were presented in the context of feminine topics and boys’ level of scientific interests was higher when scientific concepts were presented in the context of masculine topics. Conclusion. Girls’ interest in science could be substantially increased by presenting scientific concepts in the context of feminine topics. Gender differences as well as individual differences in the level of interest in scientific topics may be taken into account by creating learning environments in which students could select the context in which a certain scientific concept is embedded. 相似文献

High social anxiety is a risk factor for the incidence of social anxiety disorder (SAD). Early diagnosis and intervention may prevent more severe psychiatric courses. Self-help programs may be a convenient, accessible, and effective intervention. This study examined the efficacy of a newly developed self-help program for SAD in individuals with subthreshold social anxiety. A total of 24 highly socially anxious individuals were randomly assigned to a DVD-based self-help program or to a wait-list control group. The self-help program is based on the cognitive model according to Clark and Wells (1995; adapted to German by Stangier, Clark, & Ehlers, 2006) and comprises eight sessions. ANOVAs based on an intention-to-treat model were used for data analyses. The self-help program was well accepted; just one person withdrew during the intervention. There were significant Time × Group interactions on all primary outcome measures. For the intervention group moderate to high within-groups effect sizes up to Cohen's d = 1.05 were obtained. Between-groups effect sizes ranged from 0.24 to 0.65 in favor of the active intervention. The newly developed DVD-based self-help program seems to be a promising intervention for highly socially anxious individuals as it reduces social anxiety symptoms. 相似文献

A functional analysis identified the reinforcer maintaining feces throwing and spitting exhibited by a captive adult chimpanzee (Pan troglodytes). The implementation of a function-based treatment combining extinction with differential reinforcement of an alternate behavior decreased levels of inappropriate behavior. These findings further demonstrate the utility of function-based approaches to assess and treat behavior problems exhibited by captive animals. 相似文献

When leaders interact in teams with their subordinates, they build social capital that can have positive effects on team performance. Does this social capital affect team performance because subordinates come to see the leader as charismatic? We answered this question by examining 2 models. First, we tested the charisma-to-centrality model according to which the leader's charisma facilitates the occupation of a central position in the informal advice network. From this central position, the leader positively influences team performance. Second, we examined the centrality-to-charisma model according to which charisma is attributed to those leaders who are socially active in terms of giving and receiving advice. Attributed charisma facilitates increased team performance. We tested these 2 models in 2 different studies. In the first study, based on time-separated, multisource data emanating from members of 56 work teams, we found support for the centrality-to-charisma model. Formal leaders who were central within team advice networks were seen as charismatic by subordinates, and this charisma was associated with high team performance. To clarify how leader network centrality affected the emergence of charismatic leadership, we designed Study 2 in which, for 79 student teams, we measured leader networking activity and leader charisma at 2 different points in time and related these variables to team performance measured at a third point in time. On the basis of this temporally separated data set, we again found support for the centrality-to-charisma model. 相似文献

Focusing on a sample of nurses, this investigation examined the relationships of daily task accomplishment satisfaction (for direct and indirect care tasks) with changes in positive and negative affect from preshift to postshift. Not accomplishing tasks to one's satisfaction was conceptualized as a daily workplace stressor that should increase daily negative affect and decrease daily positive affect from preshift to postshift. Further, because of the greater centrality of direct care nursing tasks to nursing work role identities (relative to indirect care tasks), we expected that task accomplishment satisfaction (or lack thereof) for these tasks would have stronger effects on changes in affect than would task accomplishment satisfaction for indirect care tasks. We also examined 2 person-level resources, collegial nurse-physician relations and psychological resilience, as moderators of the relationships among these daily variables, with the expectation that these resources would buffer the harmful effects of low task accomplishment satisfaction on nurse affect. Results supported almost all of the proposed effects, though the cross-level interactions were observed only for the effects of indirect care task accomplishment satisfaction on affect and not for direct care task accomplishment satisfaction on affect. 相似文献

Research shows a strong link between adult attachment and mental and physical health, but little is known about the mechanisms that underlie these relationships. The present study examined self-compassion and mattering, two constructs from positive psychology literature, as potential mediators. Using survey data from a sample of 208 college students, relationships among attachment, self-compassion, mattering, and functional health were explored. Correlational analyses indicated that attachment anxiety and avoidance were strongly related to the mental health component of functional health. Mediation analyses indicated that mattering and self-compassion mediated the relationships between attachment orientation (i.e., levels of avoidance and anxiety) and mental health. These findings suggest that individuals' abilities to be kind toward themselves and their sense of belonging and being important to others are pathways through which attachment orientation relates to mental health. 相似文献

We have previously demonstrated that training on a dual n-back task results in improvements in fluid intelligence (Gf) as measured by matrix reasoning tasks. Here, we explored the underlying mechanisms of this transfer effect in two studies, and we evaluated the transfer potential of a single n-back task. In the first study, we demonstrated that dual and single n-back task performances are approximately equally correlated with performance on two different tasks measuring Gf, whereas the correlation with a task assessing working memory capacity was smaller. Based on these results, the second study was aimed on testing the hypothesis that training on a single n-back task yields the same improvement in Gf as training on a dual n-back task, but that there should be less transfer to working memory capacity. We trained two groups of students for four weeks with either a single or a dual n-back intervention. We investigated transfer effects on working memory capacity and Gf comparing the two training groups' performance to controls who received no training of any kind. Our results showed that both training groups improved more on Gf than controls, thereby replicating and extending our prior results. 相似文献

The utility of the self-report Children’s Anxiety and Pain Scale Anxiety subscale (CAPS-A) in comparison to the widely used,
observer-rated Modified Yale Preoperative Anxiety Scale (mYPAS) in assessing anxiety in children undergoing day surgery procedures
was examined. The CAPS-A test-retest reliability, concurrent validity with the Modified Yale Preoperative Anxiety Scale (mYPAS),
and sensitivity to expected increases in anxiety at stressful times during the preoperative period were examined. Levels of
observer-rated (mYPAS) and self-reported anxiety (CAPS-A) were obtained from 61 children (3 to 6 years) undergoing day surgery
procedures. The CAPS-A demonstrated adequate test-retest reliability. Concurrent validity between the CAPS-A and mYPAS scores
was poor. The CAPS-A failed to show sensitivity to the expected increases in anxiety at stressful time-points. Thus, an alternative
scoring strategy for the CAPS-A was proposed (i.e., child’s refusal to point was scored as high anxiety). Post-hoc analyses
demonstrated good concurrent and adequate convergent validity with the alternative scoring strategy. 相似文献

Two conditions for a potentially viable pluralism, based on recent interpretations of the work of George Herbert Mead, are discussed: (1) a shared conception of the psychological person acting in the biophysical and sociocultural world, and (2) a willingness to engage across differing sub-disciplinary perspectives. Even with these conditions in place, any such pluralism still faces significant challenges in avoiding ever-present challenges of creeping imperialism and interdisciplinary gloss. 相似文献
