Analyses using the Z-scores computed based on standardized norms yielded the following: There were no significant Group, Gender, or Group by Gender effects for the average Z-score across the nine domains. The MANOVA on NP domain Z-scores yielded a significant main effect for Group (F (9, 104) = 2.368, p < .019), a trend toward a significant main effect for Gender (F (9, 104) = 1.753, p < .087) and no Group × Gender interaction (p > .11). In light of the significant Group main effect, we examined individual domain scores (See Figure 1). For the Attention domain, TNAD performed better than NAC (F (1, 112) = 14.215, p < .001). Men (across both groups) performed better than women in the Spatial Processing domain (F (1, 112) = 4.298, p < .041), but there were no significant Group × Gender 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
