Origins of the Study of Abnormal Behavior and Psychology:
The study of abnormal behavior and the eventual development of psychology primarily originated from philosophy and medicine. Before becoming a recognized academic discipline in the late 19th century, inquiries about the mind and behavior were pursued within philosophical contexts. Early treatments and explanations of abnormal behavior were also deeply rooted in medical practices of the times.
Even prior to its academic formalization, aspects of psychology existed in natural science, like biology, due to its focus on the biological underpinnings of behavior. Moreover, being impacted by social interactions, psychology encompasses features of social sciences as well. The late 19th century marked a paradigm shift as psychology transitioned from philosophical speculation to more systematic, scientific inquiry.
