Deletion of Behavior theory

Comment: As per , I attempted to make it look more like a disambiguation by copy and pasting definitions from each individual article. Maybe someone who knows more about the subject can verify my work and/or simplify it. My only question is whether "learning theory" would be referred to as "behavior theory," but I left it there anyway
