Bilingual language processing after a lesion in the left thalamic and temporal regions. A case report with early childhood onset.

This case study concerns an 18-year-old bilingual girl who suffered a radiation lesion in the left (dominant) thalamic and temporal region when she was 4 years old. Language and memory assessment revealed deficits in auditory short-term memory, auditory word comprehension, nonword repetition, syntactic processing, word fluency, and confrontation naming tasks. Both languages (English and Dutch) were found to be affected in a similar manner, despite the fact that one language (English) was acquired before and the other (Dutch) after the period of lesion onset. Most of the deficits appear to be related to verbal (short-term) memory dysfunction. Several hypotheses of subcortical involvement in memory processes are discussed with reference to existing theories in this area.     

The Ponzo illusion with auditory substitution of vision in sighted and early-blind subjects

We tested the effects of using a prosthesis for substitution of vision with audition (PSVA) on sensitivity to the Ponzo illusion. The effects of visual experience on the susceptibility to this illusion were also assessed. In one experiment, both early-blind and blindfolded sighted volunteers used the PSVA to explore several variants of the Ponzo illusion as well as control stimuli. No effects of the illusion were observed. The results indicate that subjects focused their attention on the two central horizontal bars of the stimuli, without processing the contextual cues that convey perspective in the Ponzo figure. In a second experiment, we required subjects to use the PSVA to consider the two converging oblique lines of the stimuli before comparing the length of the two horizontal bars. Here we were able to observe susceptibility to the Ponzo illusion in the sighted group, but to a lesser extent than in a sighted non-PSVA control group. No clear effect of the ilusion was obtained in early-blind subjects. These results suggest that, at least in sighted subjects, perception obtained with the PSVA shares perceptual processes with vision. Visual experience appears mandatory for a Ponzo illusion to occur with the PSVA.     

Development of a fully automated system for delivering odors in an MRI environment

We describe the development and evaluation of a computer-controlled system for delivering odors in a magnetic resonance imaging (MRI) environment. The system allows a timely presentation of different odors in synchrony with MRI sequences and participant’s inspiration phase. The rise/fall time of odor deliverance has been optimized to generate prompt and strong stimulations. Equipped with a user-friendly programming interface, the system can be used reliably in a wide range of experimental paradigms. We have paid particular attention to developing a portable system that is relatively easy, rapid, and inexpensive to replicate. The equipment has been tested in a 3-Tesla MRI in a boxcar paradigm, in which stimulation conditions alternated with rest periods (no stimulation). The experiment demonstrated the good functioning of the device and its efficiency in producing the expected activation in the olfactory cortex; it also revealed some methodological and technical aspects to be improved.     

Gender Differences in PTSD diagnostic Criteria and Suicidal Ideation in a South African Police Sample

The study examined gender effects on PTSD symptoms to predict of suicidal ideation in a sample of South African police. A male (N = 161) and a female group (N = 56) of South African police officers were assessed by means of the Posttraumatic Diagnostic Scale and a short version of the Adult Suicide Ideation Questionnaire. Linear and stepwise regressions were used to determine which PTSD symptom criteria best predict suicide ideation. Hyperarousal was the primary predictor of suicide ideation in males. For females, intrusive memories was the primary predictor of suicide ideation, and of general problems.     

Job characteristics: their relationship to job satisfaction,stress and depression

This study investigated the influences of job characteristics on job satisfaction, stress and depression among South African white collar workers. Participants were managers in full-time employment with large organisations. They completed the Job Diagnostic Survey, the Perceived Stress Scale and the Beck Depression Inventory. A regression approach was used to predict job satisfaction, stress and depression from job characteristics. Job characteristics (skill variety, task identity, task significance, autonomy and feedback) predicted job satisfaction, as well as stress and depression. Job characteristics are weak predictors of perceived stress and depression. Work related factors, such as interpersonal relations and organisational culture, may better predict mental health in work settings.     

Where New Age and African Religion Meet in South Africa: the case of Credo Mutwa

A recent development among New Agers in South Africa and abroad is an interest in African traditional religion. In South Africa these two divergent groupings meet in the work of the traditional healer, Credo Mutwa. This article explores the life and teachings of Mutwa who is renowned as ‘High Sanusi of the Zulu people’ as well as keeper of ancient wisdom, writer, poet, sculptor, painter, and authority in the fields of, among others, Zulu folklore, nature conservation, astrology and extraterrestrial life. Points of convergence and divergence among New Age thought and spirituality, African Traditional Religion and the unique interpretations of Credo Mutwa are examined. It is suggested that New Agers who focus on the glamour of the ecstatic experience of the ‘sangoma’ (isangoma, traditional healer/diviner) in exploring African traditional religion are depriving themselves of much of what African traditional religion and culture have to offer in terms of spiritual development. In this regard, some concluding remarks are offered on the fruitfulness of the concept of ubuntu (‘humanness’).     

Tactics and empathy: Defences against projective identification

In this paper the author argues that interpretations made when the analyst has not done the emotional work of recognising and bearing what kind of object she has become in the patient's psychic reality will be experienced as empty tactics – even lies – rather than interpretations of integrity. However, interpreting from a position of bearing the truth of the patient's perception will be technically difficult and indicate turmoil as the analyst struggles to take in the patient's view of her. If the analyst avoids integrating her own picture of herself with the patient's picture (despite giving voice to the patient's picture) the split inside the analyst will be felt and intensify the patient's need to split. Vignettes demonstrate how the analyst, believing she is trying to understand, may become a projective‐identification‐refusing object and the issue of the analyst's disclosure of her countertransference is examined. Ultimately, the author argues, a capacity to receive and bear projective identification requires empathy with both patient and analyst‐as‐patient's object, engaged in a process about which both are ambivalent.     

Diverse thinking-style preferences in a university course in mathematics

At the University of Pretoria during 1999 the thinking-style preferences of three groups of students (ns = 50, 31, and 13) taking a first course in calculus were assessed using the Herrmann Brain Dominance Instrument. Analysis affirmed diversity in thinking-style preferences among the students and that the groups' scores represent a composite range of such preferences. Clearly, teachers of mathematics should be aware of and accommodate this diversity in instructional activities.     

Exploratory study of mindfulness in modern-day sport psychology consulting relationships

This study explored sport psychology practitioners’ mindfulness in relation to the quality of consulting relationships and value within contemporary practice. A total of 34 sport psychology practitioners from South Africa (n = 22, females = 41%) and the United Kingdom (n = 12, females = 25%) (Private practice = 68%; 15+ years’ experience = 44%) participated in this study. Data were gathered, using the Five Factor Mindfulness Questionnaire (FFMQ-SF), Working Alliance Inventory Short-Revised Form (WAI-SRT), and interviews. Spearman’s rank order correlation and thematic content analyses were employed to analyse the data. Higher levels of practitioners’ mindfulness were associated with superior consulting relationships. Specifically, positive correlations were observed between mindfulness attributes of observing, describing, non-reacting ability, and quality of the therapeutic bond, agreement on goals, and agreement on goals and tasks with clients respectively. Thematic analysis suggested mindfulness to facilitate accurate attending to present-moment experiences, and empathetic understanding of clients’ unique needs.
