Abstract
Memory research shows that one way to optimize memory is to begin with training trials that are close together (massed) and gradually expand the intervals between trials as a subject progresses. This study explored whether an expanding trials procedure improved memory in five boys with autism (ages 3–6 years, IQ 46–73) who were receiving behavioral treatment. ABAB reversal designs tested the effects of massed versus expanding trials for each subject on two tasks, chosen to be appropriate to that subject’s level of functioning. Subjects remembered correct responses trained in expanding trials much more often than responses trained in massed trials.
