Relation of ASD Symptomatology to grip control. Association between Autism Diagnostic Observation Schedule – Composite Severity Scores (ADOS-CSS) for the autism group (ASD; red circles) and (A) force accuracy (proportion of mean force to target force) and (B) force variability (standard deviation; log₁₀ scale) in Newtons (N) during visually guided (Vis; solid points) precision gripping. (C) Association between ADOS-CSS scores for the ASD group (red circles) and the slope of logarithmic force decay (square root scale) during memory guided precision gripping (Mem; empty points). Error bands represent standard error
