Reciprocity in Interaction: A Window on the First Year of Life in Autism

Figure 2

Trajectories of infant’s total motor activity versus infant’s vocalizations. (a) Trajectories (from T1 to T2) of total motor activity (b) and vocalizations total (c). Infants with ASD compared to TD infants show a reduced rate/min of motor activity at T1 and a reduced rate/min of vocalizations at T2. (b), (c) Means and standard deviations (error bars). **𝑃≤0.01; *𝑃≤0.05.
