When a new baby arrives in the family, the older child will sometimes cry more than usual and be more insistent about receiving caresses (Clucluo) from the parents. This is an example of: a. Regression. b. Acting out. c. Rationalization. d. Repression.

The correct answer is a. Regression.<br /><br />Regression is a defense mechanism where an individual reverts to an earlier stage of development in order to cope with stress or anxiety. In this case, the older child is exhibiting behaviors that are typical of a younger child, such as crying more and seeking attention from the parents. This regression to earlier behaviors is a way for the older child to cope with the feelings of jealousy or insecurity that may arise with the arrival of a new baby in the family.
