The degrees of freedom problem,which the nervous system must solve so that a person can achieve the action goal of a complex motor skill,involves determining:
A) If an open-loop or closed-loop system is needed to control the action
B) The amount of force needed to achieve an action goal
C) The organization of muscles,limbs,and joints needed to achieve an action goal
D) Which environmental cues are relevant for performing the skill

Question

Quizplus · Accepted Answer

The degrees of freedom problem refers to the challenge of organizing the many degrees of freedom (i.e. the many ways in which the limbs and joints can move) involved in a complex motor skill in a coordinated and effective way. Therefore, determining the organization of muscles, limbs, and joints needed to achieve an action goal is the most relevant factor in solving the degrees of freedom problem. The other options (A, B, and D) can be important considerations in motor control, but they do not directly address the issue of degrees of freedom.
