Abstract
Attentional processes in individuals with high-functioning autism were compared with a matched control group. Participants for the study were 103 children and adults with autism and 103 control subjects. Measures administered corresponded to Mirsky et al.'s (1991) factor analysis of tests of attention. Diminished performance was noted on measures that loaded on the Focus-Execute and Shift factors, but not on the Sustain and Encode factors. For tests in which psychomotor speed was used as the score, and the difference between groups was significant, covariance analyses were performed, using tests of basic motor functions as covariates. This procedure led to attenuation to the point of nonsignificant differences in the case of some of the attention tests. Thus, this comprehensive analysis of attention in individuals with high-functioning autism only found differences on measures in which the task placed demands on cognitive flexibility or psychomotor speed. Thus, purported attention deficits in autism may actually be primary deficits in complex decision making or psychomotor abilities.
