The Phonological Processing Deficit (PPD) hypothesis remains the most influential theory to explain why some children fail to acquire appropriate reading skills. However, current research suggests that there may be other deficits operating, and that the phonological processing deficit may be just one manifestation of a deeper underlying anatomical syndrome that originates in the cerebellar or vestibular areas of the brain. Claims that exercise regimes or programmes of vestibular stimulation may provide a ‘cure’ for developmental dyslexia (specific reading difficulties) prompt scepticism among the scientific community and raise concerns about the exploitation of vulnerable parents. The paper provides a review of research into the causes of specific reading difficulties at the behavioural, cognitive and biological level of explanation, and considers whether or not there is any theoretical basis for the use of exercise-based intervention programmes. Following consideration of recent findings from a range of scientific disciplines, it is concluded that such ‘unconventional’ methods of intervention may draw some theoretical support from the scientific literature, although researchers are cautioned to be wary of comorbidity issues. It is also concluded that more rigorous and independent evaluations of the success (or otherwise) of exercise-based interventions are needed. 相似文献

The authors report an investigation of a five-step structured study-group approach to promoting a?self-sustaining learning community that supports teachers in developing the ‘habits of mind’ necessary for improving literacy acquisition and development for urban African American students attending a low-performing, high-poverty elementary school. The authors report that over a two-year time period the conversations among the teachers at the study-group meetings changed to be more positive about the children, to make linkages between themselves and the culture the children bring to school, to enthusiasm for sharing their own strategies and engaging in public reflection, and collaborating in developing new instructional approaches. 相似文献

This essay applies Richard Gregg's theory of protest rhetoric to 705 American social movement songs from 1800 to 1985 to discover how songs enable protestors to identify against others and thus to locate themselves positively in the social hierarchy. Songs are ideal messages for ego‐enhancement because they are movement‐centered, concerned with social relationships, and highly self‐directed. Terms denoting innocent victimage and wicked victimizer dominate the selected songs, and the vision of reality is negative, dangerous, threatening, and unfair. Relatively few songs emphasize the unity, virtue, wisdom, or bravery of protestors. The self‐image contained in songs does not appear to express a strongly positive identity or locate the oppressed very high in the symbolic or social hierarchy. This self‐image would seem to fulfill three ego functions essential for the early phases of social movements: raising consciousness, allaying guilt, and reclaiming or proclaiming one's ego. However, a different self‐image is needed as movements grow, confront opposition successfully, achieve some goals, suffer setbacks, and splinter into factions. This analysis of songs indicates that protestors have difficulty making the essential transition from a self‐image of victim to one of power, worth, and virtue. They cannot extricate themselves from symbolically defensive positions in a hostile environment. 相似文献
