Outline the behaviourist approach and compare to the biological apporach

The behaviourist approach believes that all behaviour is learnt directly through operant and classical conditioning. Classical conditioning is learning through association, where a neutral stimulus becomes a conditioned stimulus when combined with an unconditioned stimulus. Whereas operant conditioning is learning through reinforcement, there are three types of reinforcement, positive reinforcement, negative reinforcement and punishment. The aim of positive and negative reinforcement is to increase a certain behaviour, however the aim of punishment is to decrease a certain behaviour. Behaviourist also believe that behaviour should only be studied if it can be observed and measured therefore rejected introspection and they also believe that learning is the same in all species therefore animals can replace humans in experimental research. One difference between the biological and behaviourist approach is that the biological approach believe in a nature viewpoint, as this approach believes that behaviour is controlled my your genes, hormones and neurochemistry whereas the behaviourist approach believe in a nurture viewpoint as this approach believes that all our behaviour is learned through the environment. One similarity between the behaviourist and biological approach is that they are both deterministic and imply that humans have no free will. Another similarity between the biological and behaviourist approach is that they both have practical applications that help improve the quality of life of humans.
