Examining how people perceive the position of their hand
Factors Affecting Sensory and Motor Learning
This study tests how people figure out where their hand is by using what they see and feel, to see if being aware of mistakes in their perception or getting feedback from moving their hand makes a difference.

What this trial studies
This study investigates how individuals estimate the position of their hand using visual and proprioceptive cues. Participants will be exposed to various visual displays that suggest their hand is in different positions and will indicate where they believe it is by pointing with their other hand. The research aims to understand how the brain integrates sensory information and adjusts for mismatches in perception. Two experiments will test the effects of conscious awareness of sensory mismatches and the impact of movement feedback on hand position estimation.
Who should consider this trial
Good fit: Ideal candidates are right-handed individuals aged 18-45 who are free of Covid symptoms and have no history of neurological or orthopedic conditions.
Not a fit: Patients with a history of neurological disorders, learning conditions, or significant orthopedic issues may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance our understanding of sensory integration and improve rehabilitation strategies for individuals with sensorimotor disorders.
How similar studies have performed: While the specific approach of this study is novel, previous research has explored sensory integration, indicating potential for meaningful insights.
Eligibility criteria
Show full inclusion / exclusion criteria
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.
