59 (31 typical and 28 ASD) children (BD and VOC > 6 or known average/above average academics but did not complete BD or VOC: 1 typical child became upset, and 1 ASD child did not meaningfully engage in VOC) completed the task. In 57 task completers with VOC scores, typical children had higher scores (12.17 +/− .517) than ASD children (10.26 +/− .491) [t(54.999) = 2.677; p = .010]. In this group mean RT had a significant negative correlation with VOC (r = −.372, p = .004). Because this is an RT study, we then matched the groups on VOC by eliminating 5 typical (and 0 ASD) subjects with VOC >= 16, resulting in the 52 children described in this table.
Positive SWAN scores indicate superior attention and negative scores reflect ADHD symptoms.
T-Test dfs for CBCL scores reflect corrections for unequal variance.
