Professor’s Note: In our investigation of psychological ideas of behavior we situated our conversation within the nature versus nurture debate. We found that neither behavior is wholly innate or wholly learned, but that it is both. However, we furthered this perspective by analyzing that behavior can be changed overall and is not fixed. Furthermore, that this change is contingent upon economic, social, and ecological contexts. The following essays by Paola Acosta and Ajourdee Joseph engages this perspective through an analysis and explanation of the contributions of theorist Jean Piaget, Michael Merzenich, J.B. Watson, Sigmund Freud, and Jonathan Metzl.
