Suppose you study two mothers who have new babies but who have different attitudes about how to care for a crying baby. Ruthie believes that every time her baby cries, she should be picked up and comforted. Glenda believes that picking up a crying baby will reinforce the crying and the child will become harder to care for. Research on this topic suggests that whose child is likely to cry less at age 1 year?

a. Ruthie's baby will probably cry less, due to a stronger development of trust and attachment. b. Glenda's baby will probably cry less, due to a stronger development of reality and responsibility. c. Glenda's baby will probably cry less, because she will learn that crying does not lead to reward. d. Ruthie's and Glenda's babies will probably cry about the same amount, regardless of how their mothers attend to their crying.
