Abstract

To test mechanisms underpinning action prediction, we directly controlled experience in a dart-throwing
training study. A motor-visual group physically practiced throwing darts and a perceptual training group
learned to associate dart throw actions (occluded video clips) with landing outcomes. A final control
group did not practice. Accuracy was assessed on related prediction tests before and after practice
(involving temporally occluded video clips). These tests were performed while additionally performing
simple, action-incongruent secondary motor tasks with either the right (observed throwing arm) or left
effector, in addition to an attention control task. Motor proficiency tests were also performed. Although
both trained groups improved their prediction accuracy after training, only the motor-visual group
showed interference associated with the right-arm secondary motor task after practice. No interference
was shown for the left-arm motor task. These effects were evidenced regardless of whether predictions
were made in response to video stimuli or static clips. Moreover, improvements on the motor proficiency
test were only shown for the motor-visual group. These results show evidence in support of motor
simulation processes during action prediction among observers with motor experience. Prediction
accuracy can be achieved via non-motor processes (for the perceptual group), but there was no evidence
that physically experienced performers could effectively switch processes to maintain prediction
accuracy
