This study explored the relationship between religiosity, hope, and subjective well-being among 430 South African university students (n = 324) and their family members (n = 104) (70.2% female; 88.4% black; 8.4% white). Data were gathered utilising measures of religiosity, hope, satisfaction with life, and affect balance. We applied structural equation modelling to examine both the direct effects of religiosity on hope, as well as the indirect effects of religiosity on life satisfaction and positive and negative affect via hope as mediator. Findings suggest pathway and agency hope to mediate the relationships between religiosity and life satisfaction, positive affect, and negative affect. Specifically, religiosity predicted higher levels of life satisfaction and positive affect, and lower levels of negative affect via agency hope. The results suggest agency hope to mediate the relationship between religiosity and subjective well-being. 相似文献

This study aimed at testing a structural model of athlete flow in a sample of South African students. A quantitative, cross-sectional research design was implemented. Participants completed self-report measures at pre-arranged times that were in close proximity to the completion of athletic activity. Student athletes (n = 235) participating in South Africa's two major sports, football and rugby, were surveyed. The instruments utilised in this study included the Short Flow State Scale-2, the Questionnaire on Experience and Assessment of Work, and the Generalised Self-Efficacy Scale. The results indicated positive relationships between the variables and established predictor paths. Teammate relationships and self-efficacy were established to as the best predictors of flow experiences of athletes. 相似文献

Insomnia is a too general term for various subtypes that might have different etiologies and therefore require different types of treatment. In this explorative study we used cluster analysis to distinguish different phenotypes in 218 patients with insomnia, taking into account several factors including sleep variables and characteristics related to personality and psychiatric comorbidity. Three clusters emerged from the analysis. The ‘moderate insomnia with low psychopathology’-cluster was characterized by relatively normal personality traits, as well as normal levels of anxiety and depressive symptoms in the presence of moderate insomnia severity. The ‘severe insomnia with moderate psychopathology’-cluster showed relatively high scores on the Insomnia Severity Index and scores on the sleep log that were indicative for severe insomnia. Anxiety and depressive symptoms were slightly above the cut-off and they were characterized by below average self-sufficiency and less goal-directed behavior. The ‘early onset insomnia with high psychopathology’-cluster showed a much younger age and earlier insomnia onset than the other two groups. Anxiety and depressive symptoms were well above the cut-off score and the group consisted of a higher percentage of subjects with comorbid psychiatric disorders. This cluster showed a ‘typical psychiatric’ personality profile. Our findings stress the need for psychodiagnostic procedures next to a sleep-related diagnostic approach, especially in the younger insomnia patients. Specific treatment suggestions are given based on the three phenotypes. 相似文献

The aim of this study was to investigate coping self-efficacy and aspects of psychosocial well-being amongst youth from marginalised backgrounds. A total of 794 black South African marginalised youth (males = 54%, females = 46%, age range between 18 and 30 years) voluntarily participated in this cross-sectional study. The participants completed surveys of coping self-efficacy, mental health, and mood disorder. Structural equation modelling was applied to construct an explanatory model for coping self-efficacy and psychosocial well-being among the marginalised youth. The resulting structural model showed that coping self-efficacy significantly and positively predicted the emotional and psychological dimensions of psychosocial well-being among the youth. Psychosocial well-being was associated with of a lower risk for symptoms of depression, anxiety, and stress in these marginalised young people. 相似文献

Mantra is a free and open-source software package for object tracking. It is specifically designed to be used as a tool for
response collection in psychological experiments and requires only a computer and a camera (a webcam is sufficient). Mantra
is compatible with widely used software for creating psychological experiments. In Experiments 1 and 2, we validated the spatial and temporal precision of Mantra in realistic experimental settings. In Experiments 3 and 4, we validated the spatial precision and accuracy of Mantra more rigorously by tracking a computer controlled physical stimulus
and stimuli presented on a computer screen. 相似文献

Visual search is modulated by action intentions 总被引:3,自引:1,他引:2
The influence of action intentions on visual selection processes was investigated in a visual search paradigm. A predefined target object with a certain orientation and color was presented among distractors, and subjects had to either look and point at the target or look at and grasp the target. Target selection processes prior to the first saccadic eye movement were modulated by the different action intentions. Specifically, fewer saccades to objects with the wrong orientation were made in the grasping condition than in the pointing condition, whereas the number of saccades to an object with the wrong color was the same in the two conditions. Saccadic latencies were similar under the different task conditions, so the results cannot be explained by a speed-accuracy trade-off. The results suggest that a specific action intention, such as grasping, can enhance visual processing of action-relevant features, such as orientation. Together, the findings support the view that visual attention can be best understood as a selection-for-action mechanism. 相似文献

We define a variant of the standard Kripke semantics for intuitionistic logic, motivated by the connection between constructive
logic and the Medvedev lattice. We show that while the new semantics is still complete, it gives a simple and direct correspondence
between Kripke models and algebraic structures such as factors of the Medvedev lattice.
