Dyadic social gaze and eye contact were examined in fragile X [fra(X)] males and in non-fra(X) autistic males as a function of age and level of communicative ability. Lag sequential analysis showed that responsive eye contact was highly correlated with age and communicative ability in non-fra(X) autistic males but not in fra(X) males. Older, more communicative non-fra(X) autistic males exhibited more responsive eye contact than their fra(X) cohorts. Implications of these observations for theory and intervention are discussed.
