Two Groups of Infants Were Exposed to the Mobile Procedure

Two groups of infants were exposed to the mobile procedure in which they learned to activate a mobile by kicking their legs. After 13 days, one group of infants watched as the experimenter jiggled the mobile over their heads. How did the infants in the two groups behave when placed in the mobile procedure at day 14?

A) Both groups did a moderate amount of kicking.
B) The infants who saw the mobile jiggled at day 13 kicked more than the babies who did not observe the jiggling.
C) The infants who did not see the mobile jiggled at day 13 kicked more than the babies who watched the experimenter jiggle the mobile.
D) Neither group appeared to remember the association between kicking their legs and the movement of the mobile.
