Statistically Characterizing Intra- and Inter-Individual Variability in Children with Developmental Coordination Disorder.

摘要: Previous research investigating children with Developmental Coordination Disorder (DCD) has consistently reported increased intra- and inter-individual variability during motor skill performance. Statistically characterizing this is not only critical for the analysis interpretation of behavioral data, but also may facilitate our understanding processes underlying DCD. Thus, primary purpose was to demonstrate utility a flexible statistical technique, random coefficient model (RCM), that characterizes in without We analyzed data from sensorimotor adaptation task which participants executed discrete aiming movements under conditions rotated visual feedback. To highlight advantages approach, we contrasted results RCM those traditionally employed general linear (GLM). The revealed differences between two groups GLM did detect; and, characterized trajectories change each individual. provides researchers an opportunity probe deficits at individual level provide new insights into heterogeneity
