Results indicated no significant (standard scores) age sample, suggesting stability during individuals DS, although several participants performed at floor standard scores Leiter-R, limiting interpretation. Growth scores, however, provide a metric absolute ability level, allow examination all participants, minimize effects. from analysis growth gain levels (growth score values) over adolescents varied by subdomain. Maternal did not explain variability or that our sample DS.
