Author Information

Primary Institution: University of Illinois at Chicago
Hypothesis
Can error augmentation enhance motor learning in tasks involving large distortions?
Conclusion
Error augmentation leads to improved performance in motor learning tasks, even with large sensory discrepancies.
Supporting Evidence
- Subjects trained with error augmentation reached targets quicker by 0.4 seconds.
- Error-augmented subjects had a reduced maximum perpendicular distance by 0.5 cm.
- Error-augmented subjects stopped moving their arms less frequently during trials.
Takeaway
When people practice reaching in a virtual world where their movements are flipped, they learn to reach better and faster if they see their mistakes highlighted.
Methodology
Subjects performed targeted reaching in a virtual reality environment with error augmentation applied to their movements.
Limitations
The study only included healthy subjects and may not generalize to populations with motor impairments.
Participant Demographics
10 healthy subjects with no history of orthopedic or neurological disorders.
