*
All scores except for those from the VABS are T-Scores (mean=50, SD=10). VABS scores are Standard Scores (mean=100, SD=15).
**
These differences are significant after controlling for multiple ANOVA or MANOVA comparisons with the False Discovery Rate (q<0.05), and using Tukey’s hsd (p<0.05) for post-hoc analyses.
