Interest in understanding cultural influences on mental processes and behaviors continues to grow in all areas of psychology, and new research and new knowledge on this topic is created constantly. Much of this new information has brought about increased awareness and appreciation for the complex and complete relationship between culture and psychology and has transformed much of how psychologists think about human nature, society, and behavior.
At the same time, the blossoming of cultural psychology and cross-cultural research has also made us acutely aware of some of the most important and basic principles of psychology, allowing us to delve more clearly and forcefully into questions about basic human nature for all. Thus, our improvements have allowed us to streamline better what we know to be true human universals—aspects of psychology that are true for all—as well as culture-specific. Moreover, we are better able to create syntheses about how the same topic can be both universal and culture-specific at the same time, and to develop hypotheses and ideas about the source of both universality and cultural similarity.
