  1. aMeans of unadjusted individual median response times; bindividual adjusted response times were natural logarithm transformed before comparison.
  2. Paired t-test, alpha level = 0.0125.
  3. 22q11.2DS, chromosome 22q11.2 deletion syndrome; df, degrees of freedom; FXS, fragile X syndrome; SD, standard deviation; TD, typically developing; TS, Turner syndrome.
