The origin of behavioralism is Hawthorne works experiment and human relations movement.
This is because the human relations movement seeks to study the behavior of people in groups or a given workforce group. In this sense, it is ideal that behavioralism seeks to exude approaches to emphasizing a given objective and allows for quantification of approaches that explain and predict the behavior of the people. This theory originated from both Hawthorne works experiment and the human relations movement that both sought to understand how social relations and setups may affect the motivation and satisfaction rate on employees. This development was based on Hawthorne’s works experiment that sought to define the behavior of people from a social relations angle.
