Abstract
:
The guidance hypothesis suggests that continuous feedback during learning may lead to feedback dependency,
with errors decreasing when feedback is provided and increasing when it is removed. This study investigates
the effect of continuous (CVF) versus non-continuous visual feedback (NCVF) on motor learning using a
muscle- controlled serious game. Subjects played the game for three consecutive days, with each day
consisting of seven training sets and one learning control set without feedback. One group received CVF
during training, while the other received NCVF. To assess transferability, the results of the learning control
sets were compared between groups. Time to success during training decreased for CVF, and average time to
reach the longest correct time period in the learning control set was higher for CVF compared to NCVF. The
number of missed goals decreased for CVF, aligning with the expected positive impact of continuous feedback
during training. However, the results for the learning control sets were inconclusive. While CVF showed a
potential dependency on feedback, the decrease in missed goals indicates improved motor learning. More test
days and subjects are required to confirm the findings and draw definitive conclusions regarding the guidance
hypothesis.
