Examination of data from the Infant Health and Development Program, a comprehensive program to avert health and intellectual impairments associated with premature low birthweight, does not show any enduring and meaningful effects on cognitive development resulting from the program. Discusses findings in terms of intelligence and its mutability.…

Long-term effects are not maintained unless: intervention sets off a chain of positive consequences, and the whole life span is taken into account. Long-term change efforts should incorporate familial and psychosocial…

The current and future state of intelligence testing of educable retarded children are discussed in terms of prediction, diagnosis, and remediation. Individual testing formats, task analysis, transfer of training, social nature of testing, degree of contextual support, and Neisser's distinction between academic intelligence and everyday thinking…

The working memory hypothesis that the development of span in children is related to increasing proficiency in the use of an articulatory loop was tested in two studies with 120 Canadian children in grades 5 and 6 and 11 and 12. Some support was found for the hypothesis. (SLD)
