Social contact (disaggregated). Time in social contact is the proportion of time a pair of children were in social contact divided by the time both children were present in the classroom. This figure disaggregates the DD group into O/DD and ASD. Social contact is the proportion of time in social contact out of the total time shared with each individual peer. Social contact is between 0.2 and 2 m and mutual relative orientation < 45°. Children in concordant dyads (O/DD-O/DD/ASD-ASD/TD-TD) spent a greater proportion of time in social contact than discordant dyads (DD-TD, p < 0.001), and O/DD-O/DD (p < 0.001) and ASD-ASD (p = 0.014) dyads were in social contact less than TD-TD dyads.
