Table 3.

Number of valid trials used for the analyses of Initial first looks, Looking time and Smiles, for each condition (1: Face vs. Toy; 2: Towards vs. Away; 3: Variable vs. Invariant) and each outcome group (LR, HR-no ASD, HR-ASD). ^*Number of valid trials out of 12 total trials for condition 1 and 2 and out of 26 total trials for condition 3. (Average number of valid trials, SD and Number of participants).
