Developmental psychology tries to study how thoughts, feelings, and behaviors, emerge and change from infancy through to adulthood. This is a vast field, so in this brief introduction we will focus largely on Piaget's stages, developed by psychologist Jean Piaget. We will also talk about some of the methods researchers use to study child development, such as longitudinal studies, cross-sectional studies, and age of onset studies. We will also tackle the age old question of nature vs. nature. There's a lot to talk about, so let's dive right in!
