Abstract

Introduction: This study aimed to directly manipulate feedback during physical execution and action observation to determine whether feedback acts as a mediating variable in the different effects of physical practice, observational practice, and motor imagery.
Methods: Sixty right-handed students participated in the study and were randomly assigned to six groups: physical practice, observational practice, mental (motor imagery) practice, physical practice without feedback, observational practice without feedback, and a control group. Participants practiced golf putting for one day (9 blocks of 18 trials each). Each training group performed the task according to their assigned condition—physically, observationally, or through motor imagery. In the physical without feedback and observational without feedback conditions, participants were prevented from observing the ball's stopping point. Performance was measured using two variables: shot accuracy and the number of dynamic degrees of freedom.
Results: In terms of movement accuracy, results showed that removing feedback in both physical and observational practice reduced performance to the level of mental imagery. However, regarding the number of dynamic degrees of freedom, motor imagery significantly differed from the no-feedback groups. Removing feedback in these two conditions did not bring their performance to the level of mental practice.
Conclusion: These findings were interpreted based on underlying cognitive and perceptual mechanisms. It was argued that physical practice is perception-based, while motor imagery relies on memory representations and is therefore more cognitively driven. Observational practice, in contrast, appears to involve a bidirectional perceptual-cognitive process.
