Analyses of ANT performance for TD girls and girls with 22q11.2DS, FXS, or TS. (A) Group analyses of response times for the neutral and no cue conditions. Response time to the neutral condition, covaried for age, showed a marginally significant difference in responses for girls with TS compared to TD girls (P=0.055). Units are the natural logarithm of the adjusted median response time (ln adjRT). (B) Group analysis of alerting index score, covaried for age, showed that girls with a NDD responded similarly to TD girls (P=0.61). Index scores are measured as the difference score for each index condition pair. (C) Group analyses of response times for the valid and invalid cue conditions. For the adjusted response times to the valid condition, covaried for age, there was a significant difference in responses between girls with TS and TD girls (P=0.03). (D) Group analysis of orienting index score, covaried for age, showed that girls with a NDD responded similarly to TD girls (P=0.35). (E) Group analyses of response times for the congruent and incongruent flanker conditions. For the adjusted response times to the congruent condition, covaried for age, there was a significant difference in responses for girls with TS relative to TD girls (P=0.02). (F) Group analysis of executive control index score, covaried for age, showed that index scores for girls with FXS and girls with TS were significantly larger than for TD girls (P=0.07). Error bars represent standard error. 22q11.2DS, chromosome 22q11.2 deletion syndrome; FXS, fragile X syndrome; ln adjRT, natural logarithm of the adjusted median response time; TD, typically developing; TS, Turner syndrome.
