Episode notes
Prospective Control in Action
- Prospective control links movement to information, guiding actions without predicting future events.
- Maintaining the relationship between movement and perceptual information leads to successful interception.
Continuous Control and Angle of Approach
- Continuous control allows for adjustments based on environmental information, unlike ballistic predictive control.
- The angle of approach effect demonstrates how hand kinematics are influenced by the ball's approach angle.
Movement Reversals and Perspective Control
- Movement reversals, where the hand moves away from and then back to the interception point, support perspective control.
- This seemingly unnecessary movement is explained by the changing online information guiding the hand.
