In Experiment 1, serial recall of supraspan digit sequences after a short delay and acquisition of a repeated digit sequence were compared in learning disabled and nondisabled children. The results showed that short-term recall and acquisition rate were lower in learning disabled than in nondisabled children, and short-term recall and acquisition rate were positively correlated. In Experiment 2, serial recall of supraspan color sequences and acquisition of this type of information were compared in learning disabled and nondisabled children. Short-term recall and acquisition rate were positively correlated. In Experiment 3, the sequence length presented to each child exceeded the number that each child could recall perfectly after a short delay. Results of this experiment showed that acquisition in learning disabled and nondisabled children was more similar than when all children acquired the same amount of information. The present findings are consistent with previous suggestions that those processes such as attention and memory that are responsible for low recall in learning disabled children are also responsible for slow acquisition in these children.
A lthough a discrepancy between intelligenceand learning is one major criteria for identifying learning disabled children, the basis for their slow learning is not completely understood. Recent findings suggest that deficient mnemonic processes (e.g., rehearsal) may be responsible for poor recall in these children. For example, recall of subspan information (three items) decreases more rapidly in learning disabled than nondisabled children (Bauer 1977a, b). In immediate free recall of supraspan lists (6 to 12 items), learning disabled children recall a smaller number of the first few items of each list than nondisabled children, and in delayed free recall, they recall a smaller number of the first and last few items presented (Bauer 1977, Tarver, Hallahan, & Kauffman 1976). Evidence from a variety of sources suggests that rehearsal is required for adequate recall in the memory tasks in which recall in learning disabled children is 30
