Which statement describes dissociation in developing movement?

Dissociation in developing movement means moving body segments independently rather than as one rigid unit. As children grow, they gain the ability to separate movements of the trunk, pelvis, and limbs, allowing more refined, purposeful actions like reaching with one arm while keeping the trunk stable or turning the head without moving the torso. This increasing independence of body parts—the ability to dissociate movements—reflects maturation of intersegmental coordination. The option describing increased dissociation of body segments best captures this progression. In contrast, greater bilateral symmetry and rigid, non-segmented movement reflect earlier, less differentiated movement patterns, and decreased trunk control would hinder dissociation.
