Factors Affecting Sensory and Motor Learning

Participant is told there will be a mismatch between their target finger and the visual indicator of target finger position. They will be shown a diagram explaining this.

Foamboard under mirror removed, making the mirror see-through and the hand directly visible. Mismatch between target hand and visual indicator will be directly visible.

After the participant points at each target, a cursor indicating final pointing position will be displayed briefly. The visual indicator of the target hand will be displaced.

After the participant points at each target, a cursor indicating final pointing position will be displayed briefly. The visual indicator of the target hand will not change, but the cursor indicating pointing hand position will change.

The visual indicator of the target hand will be displaced, but there will be no cursor to indicate the pointing hand's position.

Participants will not be told anything about the visuo-proprioceptive mismatch. Instead, they will be asked simply to attend to the target positions.
