On a gambling task that models real-life decision making, children between ages 7 and 12 perform like patients with bilateral lesions of the ventromedial prefrontal cortex (VMPFC), opting for choices that yield high immediate gains in spite of higher future losses (Crone &; Van der Molen, 2004). The current study set out to characterize developmental changes in decision making by varying task complexity and punishment frequency. Three age groups (7–9 years, 10–12 years, 13–15 years) performed two versions of a computerized variant of the original Iowa gambling task. Task complexity was manipulated by varying the number of choices participants could make. Punishment frequency was manipulated by varying the frequency of delayed punishment. Results showed a developmental increase in the sensitivity to future consequences, which was present only when the punishment was presented infrequently. These results could not be explained by differential sensitivity to task complexity, hypersensitivity to reward, or failure to switch response set after receiving punishment. There was a general pattern of boys outperforming girls by making more advantageous choices over the course of the task. In conclusion, 7–12-year-old children—like VMPFC patients—appear myopic about the future except when the potential for future punishment is high. 相似文献

We discuss the statistical testing of three relevant hypotheses involving Cronbach's alpha: one where alpha equals a particular criterion; a second testing the equality of two alpha coefficients for independent samples; and a third testing the equality of two alpha coefficients for dependent samples. For each of these hypotheses, various statistical tests have been proposed. Over the years, these tests have depended on progressively fewer assumptions. We propose a new approach to testing the three hypotheses that relies on even fewer assumptions, is especially suited for discrete item scores, and can be applied easily to tests containing large numbers of items. The new approach uses marginal modelling. We compared the Type I error rate and the power of the marginal modelling approach to several of the available tests in a simulation study using realistic conditions. We found that the marginal modelling approach had the most accurate Type I error rates, whereas the power was similar across the statistical tests. 相似文献

This study investigated the psychosocial well-being of an indigenous cultural community in South Africa, using a sequential explanatory mixed-methods design. Data on life satisfaction and emotional, social and psychological well-being were collected from 521 local residents (48% female) of Ndumo in KwaZulu-Natal, South Africa using the Satisfaction-with-Life Scale and Mental Health Continuum. In addition, interviews were conducted with 20 Ndumo residents (35% female). Findings revealed that community members had above-average levels of psychosocial well-being and exhibited significant resilience towards countering socio-economic under-resourcing, including poverty and unemployment. The community resources found to aid resilient living included being able to live off the land, a pleasant climate, personal safety, hope for a better future, and instrumental, material, and social support from philanthropic organisations. 相似文献

The aim of this research was to explore a group of black South Africans' experiences of telling their untold stories of survival about the apartheid era. The expectation was that if they did become more aware of these alternative stories, it could have a far-reaching effect on their lives. A qualitative study was conducted with a group of seven black South African survivors of the apartheid era, ranging in age from 42–62 years (males =5, females =2). These participants formed part of an earlier study investigating their perceptions regarding factors that helped them to survive the apartheid era. For the present study, unstructured interviews were conducted focusing on their subjective experiences after the initial study. Analysis of the data yielded seven prevalent themes, namely a positive experience that made a difference, gaining of a positive attitude, not all white people are bad, transgressing the past and moving on, awareness of personal strengths, forgiveness and starting to talk to family and friends. The participants became aware of their untold stories of survival and experienced a positive change within themselves, towards others, the past and the future. 相似文献

The nature of quality of life in residential care facilities: the case of White older South Africans
Lizanlé van Biljon 《Journal of Psychology in Africa》2013,23(3):201-207
This study describes the nature of quality of life (QoL) from the perspective of older South Africans (n?=?41) in residential care facilities (female =?75%; age range 62–95 years). The residents participated in individual in-depth interviews and focus groups. They also set down their narrative reflections on their QoL in journals. Data were analysed by means of interpretative phenomenological analysis. Findings reveal the resident older South Africans regard QoL as a spiritually informed worldview of life events, coping with challenges and being mindful of others. The residents perceived QoL to include proximity and quality and reciprocity with others. QoL among older people is context and people specific. 相似文献

The objective of this study was to identify occupational stressors for professional nurses in South Africa. A cross-sectional survey design was used. A stratified random sample of professional nurses (n=818; females?=?97%) in hospitals in South Africa was used. The Nursing Stress Indicator (NSI) was administrated together with a biographical questionnaire. Three internally consistent stress factors, namely lack of organisational support, job demands and nursing-specific demands, were extracted. The most severe stressors for professional nurses included staff shortages, inadequate salaries and excessive administrative duties. Work overload, fellow workers not doing their job, health risks posed by contact with patients and demands of patients were also identified as stressors. Stress was associated with specific factors, including age, position (rank), care unit, and work experience. 相似文献

The study investigated the relationship between employees’ experience of performance management and work engagement. Participants were a convenience sample of employed adults (N=202; females=59%, middle management?=?48%, White?=?54%, tenure more than 9 years?=?48%) in an organisation in the vehicle and asset-based finance industry. They completed the Performance Management Questionnaire (PMQ) and Utrecht Work Engagement Scale (UWES). Multiple regression analysis was used to determine the proportion of variance of work engagement that is explained by employees’ experience of performance management. Results revealed that only empowerment significantly predicted work engagement. These findings suggest that when employees experience performance management as empowering, they are also likely to have higher levels of work engagement. 相似文献

This study investigated the role of individual resources, notably self-efficacy, gratitude, and hope, in subjective well-being of white dormitory students at a historically white institution of higher learning. Using a convenience sample of white students (N?=?227), we tested the role of generalised self-efficacy, gratitude, and hope as indicators of a latent factor, labelled personal resources, in a structural equation model with subjective well-being as the latent output variable, measured by self-esteem and satisfaction with life. Path analyses indicated a reasonable fit between the data and our hypothesised theoretical model which proposed positive relations between levels of generalised self-efficacy, gratitude, dispositional hope, self-esteem and satisfaction with life. White students were psychologically doing well, considering above-midpoint levels obtained for levels of generalised self-efficacy, gratitude, dispositional hope, and satisfaction with life However, scores obtained for self-esteem and adult dispositional hope were below the mid-point and neutral respectively, indicating that White students do not agree that they experience high levels of these two psychological strengths. White female students experienced higher levels of hope, gratitude, and life satisfaction, while no significant gender differences were found for generalised self-efficacy and self-esteem. The results of this study highlight the potential for using psychological strengths to promote well-being in racially diverse students. 相似文献

Starting from the context in which there is an increasing emphasis on ecclesial revitalisation and churchplanting, the analytical model of the Australian National Church Life Survey (NCLS) research is introduced and described in its background and characteristics. The model shows particular interest in a specific church profile which is created based on local church surveys. The article describes the profile, examines the theological concepts and argues for in-depth empirical research in a Dutch context concerning the use of the profile. 相似文献
