On drawing trials, there was a significant effect of curvature ( p < .00001) and marginally significant effect of group ( p = .059) on beta value, such that average beta values on straighter portions of movement were significantly greater in the ASD ( M = 0.23) compared to TD group ( M = 0.19; p = .028), while more curved portions did not differ by group (ASD M = 0.35, TD M = 0.34, p = .81).

a trend toward significancep = .09so close (0.05 < p ≤ 0.1)

Kinematic Metrics On tracing trials, there was a trend toward significance ( p = .09), with the ASD group demonstrating greater beta values, further from the 2/3 PL “ideal” value ( M = 0.36; M stands for mean) compared to the TD group, which was in line with the 2/3 PL ( M = 0.33; Cohen’s d = 0.46).
