ex0429

Can active exercise shorten the time it takes an infant to walk alone?
 Twelve, one week old, male infants from white, middle-class families
 were randomly allocated to one of two treatment groups. Those in the
 active-exercise group received stimulation of the walking reflexes
 during four 3 minute sessions each day from the beginning of the
 second through the end of the eighth week. Those in the other group
 received no stimulation.
