Exploring the Reliability and Validity of the DAT-K in Grade 11 Learners in a Historically Disadvantaged School in Johannesburg,South Africa

This study explored the reliability and validity of the Differential Aptitude Test—Form K (DAT-K) in a sample of 75 learners (mean age = 17.1 years, SD = 1.13) from a previously disadvantaged school in Johannesburg. Adequate reliability coefficients were obtained but coefficients were higher for nonverbal than verbal subtests. Face validity was judged to be adequate but construct validity was questionable. All subtests correlated within cluster (verbal, non-verbal) but all the subtests with the exception of the Comparison subtest loaded highly on a single factor. Examination of the influence of language as a variable suggested that learners whose home language was an African language did significantly poorer on all the DAT-K subtests except for the Comparison subtest. These findings lend support to the arguments that psychological testing in South Africa is problematic particularly in individuals who do not speak English as their first language.     

Maternal Response to Father-Daughter Incest: Experiences of Mothers Following Disclosure

This study explored the impact of the disclosure of sexual abuse of the daughter by the father or father figure on the mother. Data were collected from seven mothers aged between 31 and 48 years whose daughters had a history of sexual abuse by the biological father, stepfather or live-in boyfriend. The children's ages ranged between 5 and 11 years with disclosure having taken place in the last two years before data collection. Data were collected using an interview schedule. The results obtained from the thematic content analysis indicate that the mothers were traumatized by the disclosure of the sexual abuse. The most prevalent symptoms were anger, anxiety, guilty, depression, insomnia, headache and fatigue. It is recommended that mothers be provided with psychological intervention in order to assist them deal with the trauma associated with the disclosure of the father-daughter incest.     

Psychological Well-Being and the Metabolic Syndrome in African and Caucasian Women in South Africa

This study explored the association between comprehensive psychological well-being and the metabolic syndrome (MS), as well as whether women without MS markers differ significantly from women with MS (three or more markers) on specific facets of psychological well-being. African (N=102) and Caucasian (N=115) women completed self-report questionnaires on psychological well-being, and biological markers for MS were determined. Results indicated a significant association between comprehensive psychological well-being and the MS in Caucasian women, but not in the case of African women. Caucasian women without MS had higher levels of perceived support from friends and family, environmental mastery, purpose in life, sense of coherence, affect balance and positive relationships than those with MS. African women without MS had higher levels of positive relationships and an optimistic explanatory style, but lower levels of perceived support from family. Further research is indicated.     

Gender,Spirituality and Psychological Well-Being

The aim of this study was to determine whether gender moderates the relationship between spirituality and psychological well-being. A secondary data analysis based on a cross sectional survey was implemented. A convenience sample of 508 participants (males = 143, females = 365; age range 18–65 with 66% in the 18–25 category) from the North-West Province of South Africa completed questionnaires on spirituality and psychological well-being after informed consent was obtained. Findings show that gender moderates the relationship between spirituality and psychological well-being. This moderation effect was stronger in the case of existential well-being rather than religious well-being as components of spiritual wellbeing, and also stronger in one of the sub-groups. Future studies may explore the role of contextual factors such as cultural orientation and other socio-demographic variables in this moderation effect, as well as gender based perceptions and practices of spirituality with a view to facilitate gender sensitive psychological well-being programmes.     

Intensive mindfulness training-related changes in cognitive and emotional experience

This study examined the role of intensive mindfulness training on changes in day-to-day experiential processing, psychological symptoms, resilience, and well-being in two groups of community adults (N = 69). Using both quasi-experimental and longitudinal methods, the study found that intensive training, operationalized as 10–12 hours of formal mindfulness practice per day for 1 month, was significantly related to increases in training-specific experiential processing capacities, namely trait mindfulness and decentering (reperceiving), in comparison to pre–post-training wait-list controls. In both training groups combined, mindfulness, decentering, and acceptance increased over the pre-training to 1-month follow-up period. Intensive mindfulness training was also related to declines in anxiety and enhanced both subjective well-being and self-compassion from pre-training to follow-up in the two training groups. Finally, increases in trait mindfulness and acceptance were related to improvements in psychological symptoms, well-being, and resilience. Future directions for this novel area of mindfulness research are discussed.     

Are courageous actions successful actions?

When asked to describe a courageous action they have taken personally, people overwhelmingly describe an action with a successful outcome (Pury, Kowalski, & Spearman, 2007 Lopez, SJ, O’Byrne, KK and Peterson, S. 2003. “Profiling courage.”. In Positive psychological assessment: A handbook of models and measures, Edited by: Lopez, SJ and Snyder, CR. 185–197. Washington, DC: American Psychological Association. [Crossref] , [Google Scholar]). Study 1 replicated these findings in observations of other people. Fifty participants described a courageous action taken by another person and made parallel ratings to Pury et al. Participants in Study 1 also described actions with overwhelmingly successful outcomes. In Study 2, 152 participants rated otherwise identical scenarios differing in success of outcome and attribution (internal vs. external) for outcome. Successful actions were rated as more courageous than unsuccessful outcomes, although this effect was attenuated for external attributions. Thus, we suggest that successful outcome is an unarticulated part of implicit theories of courage.     

Choosing optimal causal backgrounds for causal discovery

In two experiments, we studied the strategies that people use to discover causal relationships. According to inferential approaches to causal discovery, if people attempt to discover the power of a cause, then they should naturally select the most informative and unambiguous context. For generative causes this would be a context with a low base rate of effects generated by other causes and for preventive causes a context with a high base rate. In the following experiments, we used probabilistic and/or deterministic target causes and contexts. In each experiment, participants observed several contexts in which the effect occurred with different probabilities. After this training, the participants were presented with different target causes whose causal status was unknown. In order to discover the influence of each cause, participants were allowed, on each trial, to choose the context in which the cause would be tested. As expected by inferential theories, the participants preferred to test generative causes in low base rate contexts and preventative causes in high base rate contexts. The participants, however, persisted in choosing the less informative contexts on a substantial minority of trials long after they had discovered the power of the cause. We discuss the matching law from operant conditioning as an alternative explanation of the findings.     

Judgements about the relation between force and trajectory variables in verbally described ballistic projectile motion

How accurate are explicit judgements about familiar forms of object motion, and how are they made? Participants judged the relations between force exerted in kicking a soccer ball and variables that define the trajectory of the ball: launch angle, maximum height attained, and maximum distance reached. Judgements tended to conform to a simple heuristic that judged force tends to increase as maximum height and maximum distance increase, with launch angle not being influential. Support was also found for the converse prediction, that judged maximum height and distance tend to increase as the amount of force described in the kick increases. The observed judgemental tendencies did not resemble the objective relations, in which force is a function of interactions between the trajectory variables. This adds to a body of research indicating that practical knowledge based on experiences of actions on objects is not available to the processes that generate judgements in higher cognition and that such judgements are generated by simple rules that do not capture the objective interactions between the physical variables.

Psychological Adjustment to Breast Cancer

Breast cancer remains a highly prevalent and extraordinarily stressful experience for hundreds of thousands of women each year in the United States and around the world. Psychological research has provided a picture of the emotional and social impact of breast cancer on patients' lives, and of factors associated with better versus worse adjustment. Psychosocial interventions have been beneficial in decreasing patients' distress and enhancing their quality of life. Recent research also suggests that psychological factors may be related to potentially important biological disease-related processes. In addition to providing an understanding of the psychological factors in breast cancer, research in this area has provided a framework for research on adaptation to health-related stress in general.
