Two experiments were conducted to test the hypothesis that category recall is related to the quantity conservation of mass, weight, and volume. The predicted association between conservation level and category recall was observed. (JMB)

An alternating sort-recall procedure was used in three experiments to train third-, fifth-, and seventh-grade students in the use of organizational techniques as memory aids. (Author/JMB)

The availability and application of particular memory strategies by deaf children and adults was examined. In the first study, 20 younger (mean age, 6 years, 3 months) and 20 older (8 years, 8 months) children's use of rehearsal strategies was examined with a serial probe task. All four types of stimuli (animals, nonsense shapes, hands, print)…

This paper discusses studies of visual dyslexia, the nature of visual processes involved in word recognition, and the contribution of visual memory to word recognition. The paper concludes that, though defects in the physiological aspects of visual processing can lead to reading difficulties, evidence does not indicate the existence of visual…

Assessment of 60 children (ages 9-15) with learning disabilities resulted in a group with relatively intact visual planning and mental flexibility skills and a group clearly dysfunctional in these areas. Comparison of the two subtypes on measures of academic skills, visual memory, visual-motor integration, and motor speed indicated significant…

This article uses a self-organizing systems (SOS) framework to explain the complexity of learning disabilities (LD) and suggest that traditional classification schema may be inadequate. It explains principles of self-organizing systems and reviews research concerning reading and math disabilities and the roles of language, attention, working…

This study of 1,657 children (ages 7-16) found that although children with dyslexia had higher intelligence quotient scores than poor readers, the 2 groups did not differ in performance on reading, spelling, phonological processing, or most language and memory tasks. The performance of both reading-disabled groups was significantly below that of…

The paper presents a discussion of human mental processes as they relate to learning disabilities. Pathognomonic symptoms associated with disturbances to brain areas or functional systems are discussed, as well as treatment procedures. This brain behavior relationship is offered as a basis for a classification system that is seen to more clearly…

This study investigated the role of knowledge base organization in elementary school students' memory performance. In a preliminary study, students in grades 2, 6, and 10 rated words from three semantic categories for their category representativeness. Results disclosed age-related changes in how children rate words for high and low typicality.…
