This chapter is concerned with the cost of time in motor control. It concentrates on a theory that assumes that the purpose of movements is to attain a rewarding state at a minimum effort. It describes a very simply model of the human eye plant, and then observes a set of motor commands that bring the eyes to the target while minimizing a cost. This chapter shows that the motor commands that move the eyes reflect a specific cost of time, one in which passage of time discounts reward. It suggests that the motor commands that move the body may be a reflection of an economic decision regarding reward and effort.Less
