Arnold Gesell pioneered the NMT theory that the development of this faculty depends on the inhibition of subcortical centers in the brain. Researchers in Alberta developed the AIMS to capture more context about the development of this faculty than the Bayley and Peabody scales. An Indiana University experiment overturned major assumptions about this faculty’s development by first adding weights to subjects and then placing them in water. Nikolai Bernstein theorized that development of this faculty required mastering redundant (*) “degrees of freedom.” Developmental psychologists cite a “gross to specific” pattern in this faculty and break down milestones which begin with the galant, (10[1])fencing, and stepping reflexes. For 10 points, name this faculty, the ability (10[1])to control muscles to perform specific actions. ■END■
