Clark L. Hull and Neobehaviorism

Clark L. Hull is credited with being one of the first psychologist to refute the idea of Methodological Behaviorism. Hull believed that certain unobservable events of behavior could be defined so that they could be measured. To do this he thought that deductions should be drawn between the environment and the behavior itself. He suggested that there were "intervening variables" that correlated between the cause and effect of a behavior. This came to be known as "Neobehaviorism". I found this be an interesting concept especially because I had never read or heard about it before. I have taken many psychology classes and not once did I learn about Hull and Neobehaviorism. It does make sense to me though that there are certain factors or "variables" that cannot be directly observed that influence behavior.
