Visual online control processes are acquired during observational practice

• We examined motor learning following observational practice and physical practice.
• The observational practice and physical practice groups learned the timing goals.
• Kinematic data showed that visual online control processes are coded during observation.

This experiment examined whether visual online control processes are coded during observational practice. Participants physically practised an aiming sequence while yoked participants either observed (observational practice) or did nothing (control). Two target sizes were used to vary the importance of visual online control processes. Constant error and variable error indicated that participants acquired the timing constraints through physical practice and observational practice. Kinematic data confirmed that the physical practice and observational practice groups executed similar movement control. Physical practice did result in a performance advantage, but only under large target conditions. These findings indicate that visual online control processes can be effectively acquired through observational practice.
