a
Denotes the two groups that are significantly different from each other. If no notation in any groups, all three groups are significantly different from each other.
^
Denotes that these two groups are marginally significant from each other (p<.10) whereas all other groups are significantly different from each other at a minimum of p<.05.
Note: Lower SSP scores indicate higher symptom severity. N=21 High-SOR ASD, 21 Low-SOR ASD, 26 TD except for Generalization analyses where N=21 High-SOR, 20 Low-SOR, 26 TD.
