A Group of Sexually Abused Adolescents' Perceptions of their Future Life-Roles: An Exploratory Study

Sexual abuse of adolescents can have detrimental effects on their perceptions of their different future life-roles. We investigated such perceptions of students with a history of sexual abuse (n=163) as well as typically developing others (n=237). Participants completed the Life-role Inventory of the then called Human Sciences Research Council (Langley, 1990). Between-group comparisons were carried out. Adolescents with a history of sexual abuse reported negative perceptions of themselves fulfilling some of their roles in the future, being committed to these roles and attaching value to them, compared to typically developing others.     

The Term “Self-Directed Learning”—Back to Knowles,or Another Way to Forge Ahead?

The term self-directed learning has since its seminal definition in 1975 by Malcolm S. Knowles acquired a range of meanings, which has led to communication difficulties about this subject. Examination of self-directed learning from a biblical ontological–anthropological perspective reveals that, although the notion of self-directed learning as a mechanistic or deterministic process should be questioned, Knowles and colleagues were correct in ameliorating the “process part” of the definition of self-directed learning by emphasizing the freedom and agency of the learner as steward of creation. Researchers wishing to deviate from the approach by Knowles and colleagues are compelled to explain what the term designates in their particular project.     

Residual attentional capacity amongst young and elderly during dual and triple task walking

Walking is considered an automatic function which demands little attentional resources. Thus a residual attentional capacity is available for a concurrent task (dual task). Minor age-related deficits in postural control may minimize the residual attentional capacity, however this may not be detected by a simple examination of the individuals gait performance. This study investigated the use of challenging dual task combinations to detect age related changes in gait performance. Eleven community-dwelling elderly (mean age 76 years) and 13 young subjects (mean age 26 years) participated in the study. The participants walked along a figure-of-eight track at a self-selected speed. The effect of introducing a concurrent cognitive task and a concurrent functional motor task was evaluated. Stride-to-stride variability was measured by heel contacts and by trunk accelerometry. In response to the cognitive task the elderly increased their temporal stride-to-stride variability by 39% in the walking task and by 57% in the combined motor task. These increases were significantly larger than observed for the young. Equivalent decreases in trunk acceleration autocorrelation coefficients and gait speed were found. A combination of sufficiently challenging motor tasks and concurrent cognitive tasks can reveal signs of limited residual attentional capacity during walking amongst the elderly.     

The relation between gap discrimination and auditory stream segregation

Gap discrimination and stream segregation were examined using sequences of 2, 4, 8, or 16 tones. The frequency differences between tones ranged from 1/24 to 2 1/2 octaves. Judgments of stream segregation show large intersubject variability, whereas gap thresholds are comparatively stable. Gap thresholds and streaming judgments are both affected by the frequency separation between tones. However, only streaming judgments are affected by presentation rate. Gap-threshold functions show no discontinuities or plateaus with increasing frequency differences and faster presentation rates. These results suggest that stream segregation is not a primary factor limiting gap-discrimination performance in tonal sequences.     

The Need for and Possibility of a Christian Forgiveness Education in Schools

Individuals and communities occasionally need asking and giving forgiveness. Because the process of forgiving is not always well understood, it has become necessary to consider including forgiveness education in school pedagogy and in formal school programs such as Citizenship Education. This possibility is illustrated with examples from South Africa and The Netherlands. To date, forgiveness education has mostly taken the form of brief research interventions. It is recommended that forgiveness education, also from a Christian viewpoint, be given a more prominent place in school curriculums as well as in teacher education programs.
