Tests the developmental memory lag hypothesis with 22 learning disabled boys on two- and three-dimensional nonverbal tasks. Finds age-equivalent recall patterns similar to those of normal children and consistent age-related differences in nonverbal recall, thereby negating the developmental lag hypothesis. (RL)

This study addressed the extent to which performance on selected verbal and nonverbal measures contributed to the prediction of inflection learning with 20 normal boys (ages 4 to 5). Results suggested that inflection learning may be tied more to other language abilities than to nonverbal cognitive skills in normally developing boys. (DB)
