T-test IQ measure comparisons between TS and HC groups. The various subscales of the WISC-III are provided for several subsamples of the participating subjects (i.e., excluding subjects with ADHD (n = 5), subjects with OCD (n = 4), and all subjects receiving medication (n = 9))
| TS vs. HC (n= 40) | TS(ADHD excluded) vs. HC (n = 35) | TS (OCD excluded) vs. HC (n = 36) | TS (Not medicated) vs. HC (n = 31) | |||||||||
