Executive Functioning and Memory Strategy Use in Children with Autism

The Influence of Task Constraints on Spontaneous Rehearsal

An executive functioning deficit in autism should be reflected in a low level of active strategy use on memory tasks. This study was a direct examination of memory strategy use in two problem-solving situations by children with autism. Two groups with autism were tested, one high-functioning group and one with moderate cognitive impairments. All participants took part in two memory experiments to examine the effect of changing the nature of the learning situation on strategy use: one experiment used a serial recall task, and the other a recall readiness task. In contrast to previous studies, significant spontaneous strategy use was found on both memory tasks, particularly among the high-functioning group. Similarly, changing task structure was found to have an important impact on increasing strategy use, particularly for the moderate-functioning group. However, the overall rate of strategy use for the children with autism was still lower than would be expected for non-handicapped groups. The results support an executive functioning deficit interpretation, but a deficit that is less extensive among high-functioning individuals. Practical implications of the study in terms of cognitive training are also discussed.
