In your psychology courses, you will study how various cultures respond to psychological concepts and what effect it has on the way people behave. For instance, one culture may have a particular way of disciplining children completely different from another culture's methods.

The paper may explore how the child would grow up differently from one culture to the next and discuss the psychological advantages and disadvantages each culture has on a child.

Ideas include "Predictive Parenting for 18-Month-Olds," "Parent and Infant Dependencies" and "Time Out for Your Child: Psychological Friend or Foe."
