Summary
Motor control theories suggest movement is governed by recognition. This study found active movements deteriorated without feedback, unlike passive ones, suggesting recall and recognition are separable in slow movements.
Area of Science:
- Motor control
- Human movement science
- Cognitive psychology
Background:
- Motor learning theories propose that movement control relies on recognition processes.
- Performance in slow positioning movements is hypothesized to be independent of response mode (active vs. passive).
Purpose of the Study:
- To investigate whether recall and recognition are separable processes in slow motor movements.
- To test the hypothesis that movement performance is independent of response mode if governed solely by recognition.
Main Methods:
- Two groups of subjects learned a criterion slow positioning movement.
- One group performed actively, the other passively.
- Knowledge of Results (KR) was withdrawn after the acquisition phase for both groups.
Main Results:
- No significant performance differences were observed between active and passive groups during acquisition trials.
- Upon KR withdrawal, the active group's performance deteriorated significantly.
- The passive group's performance remained stable after KR withdrawal.
Conclusions:
- The findings suggest that recall and recognition are distinct components in the control of slow movements.
- The type of information available to the performer (active vs. passive) influences movement stability after feedback withdrawal.
- This challenges theories suggesting slow movements are governed solely by recognition.
