Note: LRC: Low-risk controls; HRA-: High-risk autism with no clinical diagnosis; CSBS: Communication and Symbolic Behavior Scales. All eye-tracking variables averaged across the three emotional faces. Mullen Scales of Early Learning Early Learning Score (MSEL ELC) partialed out of all CSBS correlations. Correlations (r) shown with p-value in parentheses.
