interactions for any domain. Finally, NAC had higher GCIS scores (reflecting worse performance) than TNAD (p ≤ .04). It should be noted that no TNAD had a GCIS higher than 3 while three NACs had a GCIS of more than 4 (5, 5, 6). A second Mann-Whitney U test with these NAC outliers removed yielded no significant difference between Groups (p = 0.123). In order to determine whether the four outlying GCIS accounted for the Group difference in the Attention domain (reported above) we repeated the Attention domain analysis without these subjects. The Group difference was still significant (p < .001).
