Factors Affecting Sensory and Motor Learning
Indiana University
300 participants
Apr 29, 2022
INTERVENTIONAL
Conditions
Summary
How participants perceive the position of their own hand in various contexts will be examined. This will include changing the visual display to suggest the hand is in a slightly different position, and asking participants to indicate where they think it is by pointing with their other hand.
Eligibility
Inclusion Criteria3
- Between the ages of 18-45 years old
- Right-handed.
- Covid has been found to have neurological effects in some people, but mostly the effects on sensorimotor control and neurophysiology are unknown. So we will only include individuals who report being free of Covid symptoms in week preceding testing.
Exclusion Criteria4
- Past or present history of seizure, stroke, any brain or peripheral nerve disease, severe head trauma, or spinal cord surgery.
- Learning or attention conditions such as ADHD.
- Orthopedic or pain conditions, or a history of seriously injured bones, joints or muscles in either arm.
- Lack of normal or corrected-to-normal vision.

Interventions
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.
