A serial recognition task was used to compare performance of two age groups of learning disabled children (mean chronological ages 8.1 and 10.6) with 2- and 3-dimensional representations of nonlabeled 8-point random shapes. (Author/JMB)

Using strict and lenient mathematics achievement cutoff scores to define a learning disability, respective groups of children who are math disabled (MLD, n = 15) and low achieving (LA, n = 44) were identified. These groups and a group of typically achieving (TA, n = 46) children were administered a battery of mathematical cognition, working…

Compares the development of working memory in normally achieving children and learning disabled children. Results show a growth of working memory as a function of age. Deficits in working memory for subtypes of learning disabled children are discussed. (RJC)

A stages-of-learning model was used to examine effects of picture-word manipulation on storage and retrieval differences between disabled and nondisabled grade 2 and 6 children. Results showed that disabled students are poorer at memory tasks and in developing the ability to reliably retrieve information than nondisabled children. (Author/RH)
