nature vs. nurture
Developmental psychology is a field of study that focuses on how individuals develop and change over the course of their lifetimes. One of the key intellectual issues that is relevant to developmental psychology is the nature versus nurture debate, which addresses the extent to which our development is influenced by genetic factors (nature) versus environmental factors (nurture). Developmental psychologists study how both nature and nurture interact to influence our development, and they seek to understand the roles that genetics, the environment, and other factors play in shaping our psychological and behavioral characteristics.
