Twenty years after the advent of democracy in South Africa (SA), there have been some successes in the achievement of greater equality, access and inclusion for many persons with disabilities. The move towards inclusive education may, however, have had unanticipated embodied consequences for people positioned discursively as included, but who in fact may in some respects be further marginalised than they had been under apartheid. We describe ethnographic research conducted in a special needs school in SA to explore the lived experiences of children with cerebral palsy and their involvement in physical activity. Our study shows how inclusive educational practices in SA have impeded involvement in sport for some children with motor impairments because of resource limitations and other historic reasons. This paper raises important questions about the role of community psychology in recognising, naming and contributing to action around injustices, which may be hard to see but which can have profound effects on the lives and bodies of those who experience exclusion.

Strength training is often prescribed for children with cerebral palsy (CP); however, links between strength gains and mobility are unclear. Nine children (age 14?±?3?years; GMFCS I-III) with spastic CP completed a 6-week strength-training program. Musculoskeletal gait simulations were generated for four children to assess training effects on muscle forces and function. There were increases in isometric joint strength, but no statistical changes in fast-as-possible walking speed or endurance after training. The walking simulations revealed changes in muscle forces and contributions to body center of mass acceleration, with greater forces from the hip muscles during walking most commonly observed. A progressive strength-training program can result in isometric and dynamic strength gains in children with CP, associated with variable mobility outcomes.  相似文献

Multilevel analysis is an appropriate tool for the analysis of hierarchically structured data. There may, however, be reasons to ignore one of the levels of nesting in the data analysis. In this article a three level model with one predictor variable is used as a reference model and the top or intermediate level is ignored in the data analysis. Analytical results show that this has an effect on the estimated variance components and that standard errors of regression coefficients estimators may be overestimated, leading to a lower power of the test of the effect of the predictor variable. The magnitude of these results depends on the ignored level and the level at which the predictor variable varies, and on the values of the variance components and the sample sizes.  相似文献

The modality effect occurs when audio/visual instructions are superior to visual only instructions. The effect was explored in two experiments conducted within a cognitive load theory framework. In Experiment 1, two groups of primary school students (N = 24) were presented with either audio/visual or visual only instructions on how to read a temperature graph. The group presented with visual text and a diagram rather than audio text and a diagram was superior, reversing most previous data on the modality effect. It was hypothesized that the reason for the reversal was that the transitory auditory text component was too long to be processed easily in working memory compared to more permanent written information. Experiment 2 (N = 64) replicated the experiment with the variation of a reduced length of both auditory and visual text instructions. Results indicated a reinstatement of the modality effect with audio/visual instructions proving superior to visual only instructions. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Physiological, cognitive, and emotional factors were examined throughout the treatment of a psychotic child. Heart rate, latency and accuracy in task performance, behavioral indices of stress (e.g., muscular tension, facial expression), and frequency of autistic mannerisms were measured concurrently. Both contemporaneous relationships and patterns of change suggested that autistic behaviors were organized and psychologically meaningful. Self-stimulation, conflict, and negativism (deliberate erroneous performance) occurred predictably, were intimately related, and were associated with specific patterns of heart-rate change. The changing function of self-stimulation across treatment and the centrality of negativism in this child's disturbance were discussed.This research was supported in part by a Program Project Grant from the National Institute of Child Health and Human Development to the Institute of Child Development, University of Minnesota (1 PO1 IID05027).  相似文献

This study was an attempt to determine whether the role choice dimension of Holland's theory was applicable to vocational high school students. The results of the study indicate that students with a clear role choice have significantly higher mean achievement scores, are more satisfied with their training program and have a lower attrition rate than students with an unclear role choice. These results seem to suggest that school counselors should listen to what students say they want to do in their work role.  相似文献

The state-dependent theory of the relationship between affective states and memory holds that recall will be best when the affective state at recall matches that during learning. Sequential happy, neutral, and sad affective states that were either consistent (e.g., Happy-Happy) or inconsistent (e.g., Sad-Neutral) were experimentally induced in preschool children prior to encoding and then again prior to retrieval (free and cued recall, recognition memory). Facial ratings indicated that the inductions were effective in inducing affect. Nevertheless, emotional states did not influence children's ability to recall items under free or cued conditions, and recognition memory was essentially perfect for all subjects. Thus, there was no evidence for state-dependent learning or for a positive loop between subjects' positive affect at retrieval and memory for positively rated information. Results are discussed in terms of the generally inconsistent findings in the literature on the role of affect in children's memory and factors that may limit affective state-dependent learning in children.This research was supported by Research Grant No. 11776 from the National Institute of Child Health and Human Development to Marion Perlmutter, by Grant BNS 78-01108 from the National Science Foundation to John C.
