Grounded in expectancy value theory (EVT), a moderated mediation model predicting children’s physical activity (PA) enjoyment was tested. Ability beliefs and subjective task value were initially investigated as mediating the relationship between social support from friends and PA enjoyment. It was hypothesized that children play an active role in this socialization process with support seeking self-efficacy moderating the mediated relationships. Findings revealed PA social support from friends and PA enjoyment was mediated by PA ability beliefs, but this mediated relationship was conditional on children having average-to-high levels of support seeking self-efficacy. The mediated relationship between PA social support from friends and PA enjoyment through subjective task value was not moderated by support seeking self-efficacy. Results support the importance of instilling confidence in children to seek out PA support in order to maximize opportunities for PA enjoyment and suggest pathways may be more complex than originally posited in EVT.  相似文献

We investigate the role of strengths use in the workplace by drawing on self-determination theory (SDT) to propose that strengths use at work can yield performance benefits in terms of task performance and discretionary helping, and that the social context, in the form of leader autonomy support, can promote employees’ strengths use. Further, consistent with an interactional psychology perspective, we contend that the relationship between autonomy support and strengths use will be stronger among individuals with strong independent self-construal. We tested the model using matched data from 194 employees and their supervisors and found evidence for the relevance of strengths use at work, even after accounting for the role of intrinsic motivation. In addition to providing practical implications on developing employee strengths use and how to do so, this study advances theory and research on workplace strength use, SDT, and positive organizational behavior.  相似文献

The goal of this work was to test a theoretical model of relational catalyst (RC) support provision that promotes thriving in non-adverse times. We tested a pathway proposed by Feeney and Collins that explains how RC support in the context of close relationships might lead to thriving. We proposed that once RC support has been received, it functions through the mechanisms of being perceived to be responsive to one’s needs and promoting perceived capability. Perceived capability should promote indices of thriving including self-esteem, goal accomplishment, growth, and specific and general availability of support. This model was supported in two studies of married couples using observational and longitudinal methods surrounding the support of goal strivings. Results indicate that (a) partner support of goal strivings predicted important indicators of thriving over time, and (b) both received and perceived RC support work together and play important roles in predicting these outcomes.  相似文献

This article examines the relationship between perceived organizational support, proactive personality, and perceived employability in a sample of workers over 50. An online questionnaire assessing these variables were filled by 213 employees. Results confirmed that individual dispositions have a significant impact on perceived employability but also indicated that organizational context may have a greater impact on employability. The implications of the findings are discussed, and suggestions are offered for future research on employability.  相似文献

The authors aimed to compare the weight bearing on hands during sit-to-stand (STS) movement in children with cerebral palsy (CP) and typical children (TC), verify its effect on postural oscillation, and analyze the relationship between weight bearing on hands and postural oscillation. Twenty children with CP (Gross Motor Function Classification System levels I and II) and 35 TC performed STS with and without anterior hands support. Mann-Whitney test compared weight bearing between groups. Wilcoxon test investigated differences in postural oscillation between the conditions with and without anterior hand support for both groups. The Spearman correlation tested the relationship between weight-bearing and postural oscillation during the hand support condition. Children with CP bore more weight on hands than TC to perform STS. The hand support reduced postural oscillation during the second phase of STS in both groups. In the CP group, greater weight bearing was related with lower postural oscillation in the beginning of STS. Although children with CP were able to perform STS without support, they bore more weight on their hands to perform the task than TC. Moreover, children with CP and TC use mechanical and somatosensory information to modulate their postural control during STS in different ways.  相似文献

The authors examined several issues related to the motor learning benefits resulting from giving learners choices. In 2 experiments, participants practiced a novel task, throwing a lasso. In Experiment 1, giving learners a choice ostensibly irrelevant to performance (color of mat under target) resulted in enhanced learning relative to a control group. The choice group also reported more positive affect. Experiment 2 compared the effectiveness of task-irrelevant (mat color) versus task-relevant (video demonstrations of the skill) choices. In both choice groups, each participant was yoked to a participant in the other group, and each received the same mat color or saw the video demonstration, respectively, as chosen by their counterpart in the other group. In the control group, participants were yoked to their respective counterparts in each of the choice groups. On a retention test, the 2 choice groups did not differ from each other, but both outperformed the control group. The affective and learning effects seen when learners are given choices, and the fact that task-relevant and task-irrelevant choices resulted in similar learning benefits, are consistent with a content-neutral mechanism for the effects of choice on learning, as described in the OPTIMAL theory of motor learning (Wulf &; Lewthwaite, 2016 Wulf, G., &; Lewthwaite, R. (2016). Optimizing performance through intrinsic motivation and attention for learning: The OPTIMAL theory of motor learning. Psychonomic Bulletin &; Review, 23, 13821414. https://doi.org/10.3758/s13423-015-0999-9.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]).  相似文献

为考察自我厌恶对大学生同伴关系的影响机制以及抑郁和社会支持在其中的作用,采用中文版自我厌恶量表、同伴关系量表、抑郁自评量表和青少年社会支持评定量表对443名大学生进行调查。结果发现:(1)自我厌恶与大学生同伴关系呈显著负相关;(2)抑郁和社会支持在自我厌恶对大学生同伴关系的影响过程中起链式中介作用。结果表明,通过降低大学生的自我厌恶和抑郁水平,同时充分发挥社会支持的作用,有助于提升大学生的同伴关系。  相似文献

This study examined the effects of life events and social support on depression in 200 dialysis patients. The instruments used included the Beck Depression Inventory, a modified version of Sarason's Life Experiences Survey and a Social Support Inventory (SSI) constructed by the authors. The SSI consisted of five quantitative measures and three measures of perceived social support. These measures were found to be internally consistent and stable over time. Results showed that clinically depressed dialysis patients reported fewer positive life events and appraised life events more negatively than non‐depressed patients. The total number of life events and the number of negative life events were not found to differentiate between depressed and non‐depressed patients. With regard to social support variables, results showed that depressed patients reported less frequent actual contact and telephone contact with others and perceived a smaller amount and less availability of social support and less satisfaction with perceived social support along the functional dimensions of emotional, informational, appraisal and instrumental support and social companionship. The results were found to provide support for a main effect model of social support and not for a buffering model. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

This paper is concerned with a specific type of problem, namely dynamic decisions, for which most techniques fail to provide adequate solutions. Here, we present two of the most promising optimization techniques, partially observable Markov decision processes (POMDP) and dynamic decision networks (DDN), while arguing which is the most suitable for this problem domain.
