ObjectivesKimiecik and Stein's (1992) flow model proposed that personal and situational factors affect the experience of flow. Singer, 1988, Singer, 2000 argued that different mental processes underlie self-initiated and reactive performances. The first purpose of this study was to examine main and interaction effects between imagery use and confidence on flow state in different performance contexts. The second purpose was to assess main and interaction effects between flow state, imagery, and confidence on self-paced service and externally-paced groundstroke performance in tennis.DesignThis field study used a repeated-measures design.MethodA pilot study was conducted to inform the set up of the two performance contexts. Flow states were assessed on two separate occasions, (a) for the service performance, and (b) for the groundstroke performance. A total of 60 junior tennis athletes completed imagery and confidence measures before the field test.ResultsA significant interaction between imagery and confidence was found for flow state in the groundstroke but not in the service task. No significant interaction effects were found for performance outcome. Flow state significantly predicted groundstroke performance, and imagery and confidence predicted service performance.ConclusionsThe examination of flow in different performance contexts is challenging. Imagery and confidence are central to the experience of flow. Flow state appeared to be more important for the externally-paced than self-paced task. The relationship between flow and performance is complex, which requires the conceptual expansion of Kimiecik and Stein's (1992) flow model.  相似文献

The aim of the present study was to investigate how saccadic selection relates to people’s awareness of the saliency and identity of a saccade goal. Observers were instructed to make an eye movement to either the most salient line segment (Experiment 1) or the only right-tilted element (Experiment 2) in a visual search display. The display was masked contingent on the first eye movement and after each trial observers indicated whether or not they had correctly selected the target. Whereas people’s awareness concerning the saliency of the saccade goal was generally low, their awareness concerning the identity was high. Observers’ awareness of the saccade goal was not related to saccadic performance. Whereas saccadic selection consistently varied as a function of saccade latency, people’s awareness concerning the saliency or identity of the saccade goal did not. The results suggest that saccadic selection is primarily driven by subconscious processes.  相似文献

The deterioration of performance over time is characteristic for sustained attention tasks. This so-called “performance decrement” is measured by the increase of reaction time (RT) over time. Some behavioural and neurobiological mechanisms of this phenomenon are not yet fully understood. Behaviourally, we examined the increase of RT over time and the inter-individual differences of this performance decrement. On the neurophysiological level, we investigated the task-relevant brain areas where neural activity was modulated by RT and searched for brain areas involved in good performance (i.e. participants with no or moderate performance decrement) as compared to poor performance (i.e. participants with a steep performance decrement). For this purpose, 20 healthy, young subjects performed a carefully designed task for simple sustained attention, namely a low-demanding version of the Rapid Visual Information Processing task. We employed a rapid event-related functional magnetic resonance imaging (fMRI) design. The behavioural results showed a significant increase of RT over time in the whole group, and also revealed that some participants were not as prone to the performance decrement as others. The latter was statistically significant comparing good versus poor performers. Moreover, high BOLD-responses were linked to longer RTs in a task-relevant bilateral fronto-cingulate-insular-parietal network. Among these regions, good performance was associated with significantly higher RT-BOLD correlations in the pre-supplementary motor area (pre-SMA). We concluded that the task-relevant bilateral fronto-cingulate-insular-parietal network was a cognitive control network responsible for goal-directed attention. The pre-SMA in particular might be associated with the performance decrement insofar that good performers could sustain activity in this brain region in order to monitor performance declines and adjust behavioural output.  相似文献

Interviews with 15 emigrant South African psychologists revealed that they left South Africa mainly for two reasons, the policies of the government and the academic situation. In this article, we report on this group's interest in psychology, commonalities between them, and their views on South African psychology.  相似文献

SUMMARY

Two studies examined the spiritual experiences of older women shortly after their husbands' deaths. The central question was, in the process of becoming and being a widow, do the older women begin a reflective dialogue with existential questions and initiate spiritual journeys as recent widows? One study is based on the widows within a random sample of older adults. The second study involved in-depth interviews with 15 recent widows. Both studies included Batson's measures of means, ends, and quest religious orientations. There was more evidence of an “ends” (intrinsic) orientation among the widows than “means” (extrinsic) for religious involvement; there was also no change over time in these orientations. Their quest orientation, however, became significantly less prevalent in the follow-up. It seems that women indeed quested, and by follow-up engaged their faith for religious consolation. Data from Study 2 revealed two themes: religious involvement provided a sense of continuity and direction, and through faith and prayer the women were able to (re)find meaning and purpose to life.  相似文献

ABSTRACT

As older adults approach the end of their lives, it is not uncommon to find a decrease in subjective well-being. However, a number of studies have indicated that elders with an intrinsic rather than extrinsic religious orientation often are able to keep a high level of subjective well-being even if they are close to death. In a previous quantitative study, only intrinsic religiosity was indirectly and positively related to subjective well-being in a sample of 103 relatively healthy older adults and 19 hospice patients (aged 61 +), mediated by shared spiritual activities and purpose in life. Extrinsic religiosity, by contrast, was indirectly and negatively related to subjective well-being. To explore in greater depth how religious orientation might influence subjective well-being at the end of life, we used the method of objective hermeneutics to examine semi-structured qualitative interviews with three older male hospice patients (aged 79, 80, and 98) on religion/spirituality and attitudes about death and dying. Results of the analyses revealed that the intrinsically religious respondent maintained his sense of cosmic purpose in life, which continued to be a source of satisfaction for him, unaffected by his terminal illness. The two extrinsically religious respondents, however, did not find solace in their religion and, hence, were unable to cope with their physical and emotional dependence and vulnerability. The findings suggest that an intrinsic religious orientation is most likely to be related to a cosmic sense of purpose in life, which facilitates subjective well-being even in the face of death.  相似文献

The authors compared the associations among perceived maternal socialization goals (self-development, filial piety, and collectivism), perceived maternal parenting styles (authoritative, authoritarian, and training), and the social-emotional adjustment (self-esteem, academic self-efficacy, and depression) between Chinese and European American young adults. The mediation processes in which socialization goals relate to young adults’ adjustment outcomes through parenting styles were examined. Results showed that European American participants perceived higher maternal self-development socialization goals, whereas Chinese participants perceived higher maternal collectivism socialization goals as well as more authoritarian parenting. Cross-cultural similarities were found in the associations between perceived maternal authoritative parenting and socioemotional adjustment (e.g., higher self-esteem and higher academic self-efficacy) across the two cultural groups. However, perceived maternal authoritarian and training parenting styles were found only to be related to Chinese participants’ adjustment (e.g., higher academic self-efficacy and lower depression). The mediation analyses showed that authoritative parenting significantly mediated the positive associations between the self-development and collectivism goal and socioemotional adjustment for both cultural groups. Additionally, training parenting significantly mediated the positive association between the filial piety goal and young adults’ academic self-efficacy for the Chinese group only. Findings of this study highlight the importance of examining parental socialization goals in cross-cultural parenting research.  相似文献

Research shows that challenging jobs stimulate employee learning and retention. Nevertheless, empirical knowledge on what influences the amount of challenging tasks employees perform in their job is lacking. In this study, we examined the extent to which the performance of challenging tasks is related to employees' and supervisors' goal orientations. We found a positive relationship between employees' mastery-approach orientation and the performance of challenging tasks. Furthermore, if supervisors had authority over the tasks of their employees, supervisors' goal orientations were related to employees' task challenge. Performing challenging tasks was negatively related to supervisors' performance-approach orientation and positively related to supervisors' performance-avoidance orientation.  相似文献

Research on work engagement has mainly focused on the role of job and personal resources and has ignored the possible impact of personal demands workers develop with regard to their work. The aim of our study was to test the reciprocal relationships that job resources, personal resources, and personal demands, operationalized as performance expectations, share with work engagement. Three-wave longitudinal data were collected in a Belgian public institution (N?=?473). Results confirm the causal effects of job resources, personal resources, and performance expectations on work engagement. Reciprocal relationships are not significant. Results are discussed with regard to the impact of changes in job and personal resources and performance expectations on work engagement. Practical implications including reinforcement of Human Resources practices such as appraisal interviewing and career management are also discussed.  相似文献

Seligman recently introduced the PERMA model with five core elements of psychological well-being: positive emotions, engagement, relationships, meaning, and accomplishment. We empirically tested this multidimensional theory with 516 Australian male students (age 13–18). From an extensive well-being assessment, we selected a subset of items theoretically relevant to PERMA. Factor analyses recovered four of the five PERMA elements, and two ill-being factors (depression and anxiety). We then explored the nomological net surrounding each factor by examining cross-sectional associations with life satisfaction, hope, gratitude, school engagement, growth mindset, spirituality, physical vitality, physical activity, somatic symptoms, and stressful life events. Factors differentially related to these correlates, offering support for the multidimensional approach to measuring well-being. Directly assessing subjective well-being across multiple domains offers the potential for schools to more systematically understand and promote well-being.  相似文献
