In One Study, Preschoolers Who Liked to Draw Were Told

In one study, preschoolers who liked to draw were told they could earn a certificate with a large gold star and a red ribbon. Other children drew a picture but either didn't get an award or got one unexpectedly. A week later, the experimenter returned to observe what activities the children chose to engage in during free-play time and found which of the following?

A) The children who got their expected award for drawing spent only half as much time drawing as those who did not get an award or who received it unexpectedly.
B) The children who got their expected award for drawing spent double the amount of time drawing as those who did not get an award or who received it unexpectedly.
C) The children who did not get an award spent only half as much time drawing as those got their expected award for drawing.
D) There were no differences in the behavior of the children who got their expected award and those who did not get an award or who received it unexpectedly.
