  1. Mean, standard deviation (SD) and range for age and standardized scores on reading, math fluency and intelligence for participants with Time 1 data (n = 132) and for participants with longitudinal data (n = 63).
  2. Note. Reading Fluency: Word Reading Efficiency standard score on the Test of Word Reading Efficiency (TOWRE); Math fluency: Standardized score on the Math Fluency test from the Woodcock-Johnson III (WJ-III); Intelligence: Full IQ standardized scores on the Wechsler Abbreviated Scale of Intelligence (WASI) (verbal + performance).
