Document Summary

How movements and actions interact with themselves or other movements: combination of body movements with parameters that is smooth, well timed and efficient. Speed-accuracy trade-off: faster you move, the less accurate/ more mistakes you"ll make, fitts law: relation between movement time (mt), distance (d), target width (w, index difficulty: w increases, movement easier. Impulse variability explanation: force variability- force production increases with increasing force. Approach max force, variability must decrease: muscle impulse- increase in force of contraction, increase in force variability, discrete movements, we increases as discrete movement is faster or moving a farther distance.
