Radical behaviourism is an offshoot of behaviourism first described by B.F Skinner. Radical behaviourism is different from the previous idea of behaviourism because it accepts that internal states such as emotions and feelings exist and treats them as another behaviour to be studied. It also doesn’t concentrate on the “tabula rasa” argument, because it includes genetic and inherited explanations of behaviour.
One radical behaviourist is Clark Hull, who believed all human behaviour could be explained in terms of physics and maths- he was quoted as saying “a psychologist should not only understand mathematics, but think in mathematics”. Hull’s Mathematico-Deductive Theory was based on the factors affecting the gap between Stimulus and Response- known as “E”- and tried to transform these factors, such as Inhibition, Fatigue and Motivation, into mathematical functions.
This produced mathematical formulae that he believed explained behaviour, such as;
E = (sHr x D x K x V) – (sIr + Ir) +/- sOr.
However, because Hull thought mathematically, he defined all of these variables so precisely that they weren’t able to be generalised to other situations- this made his work limited meaning it was not widespread in psychology. Hull’s later work was studying hypnosis, trying to prove the extreme claims of hypnotists. While he did manage to show that things such as hypnotic memory loss existed, he also showed that hypnosis isn’t a special state but a form of suggestion, and some people are more suggestible than others.
The main method of radical behaviourism is Operant Conditioning, and they also use a lot of animal experiments in the same way as behaviourism. Skinner was famous for the “Skinner box” (although he hated that term); a Skinner box was simply a box containing the animal, a thing that could be changed such as a lever, and a way of delivering a reward, such as a food tube. This invention may sound either fairly pointless or pretty cruel,but was actually neither; it was used in many different types of experiment, and was also operated by Skinner on a strict “no punishment” policy.
