Basic Science Clinical Trial
Official title:
Factors Affecting Sensory and Motor Learning
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.

Age group | 18 Years to 45 Years |
Eligibility | Inclusion Criteria: - 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 Criteria: - 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. |

---|---|---|---|---|
Primary | Realignment | Measured by comparing where the subject points on a touchscreen when indicating perceived position of visual and proprioceptive targets early vs. late in the behavioral task. | 1 day | |
Secondary | Visuo-proprioceptive weighting | The degree to which participant relies on vision vs. proprioception when both are available. Measured by comparing where the subject points on a touchscreen when indicating perceived position of visual vs. proprioceptive targets. | 1 day | |
Secondary | Target estimation variance | Variance with which participant estimate visual and proprioceptive target positions. Computed from where subjects point at targets on a touchscreen. | 1 day. |
