One day Ellie takes her 2-month-old baby, Eric, to her friend's home where Eric is put in a rocking cradle. Eric lays quietly at first, but soon learns that if he wiggles and waves his arms the cradle will rock. Several weeks later, Ellie and Eric return to the friend's house. How would you expect Eric to respond when he is once again placed in the cradle?

B) Eric is likely to remember the cradle and start wiggling and waving his arms as soon as he is placed in the cradle.
C) Eric is likely to remember how to make the cradle move only if Ellie gives him a cue by rocking the cradle right after he is put in it.
D) Eric is likely to remember how to make the cradle move but will no longer be interested in making it move.
