Correlations between the movement index (MI) and behavioural indices in each time window. (A) Overall averaged time-series data of the MI after the first onset of body stillness in the TD children (n = 17) and children with ASD (n = 17). (B) Time series of the correlation coefficients between the MI and social ability as evaluated by the SRS total scores. A positive value indicated that a higher rate of body movement was associated with a lower social ability. (C) Time series of the correlation coefficients between the MI and adaptive behaviour as evaluated by the Vineland Adaptive Behavior Scales. A positive value indicated that a higher rate of body movement was associated with severe maladaptive behaviour. (D) Time series of the correlation coefficients between the MI and ADHD symptoms as evaluated by the ADHD-RS. A positive value indicated that a higher rate of body movement was associated with higher ADHD symptoms.
