Behavioural Model of Abnormality Conditioning
Classical conditioning Pavlov Dogs
Watson & Raymer (1920) Little Albert
Operant conditioning
'Association' 'Reinforcement' Good behaviour rewarded, bad behaviour punished -Addictions
-Eating disorders
-OCD Token economy 'based on lab experiments that
deal with observable behaviour. Behaviourable psychologists are
concerned with the learning of
behaviours through experience' Treatment Strengths and
weaknesses Systematic desensitisation Flooding Token economy Phobias Paraphilias Effectiveness Effective but traumatic Ethics Choy et al (2006) Good behaviour rewarded Jones (1924) Newman & Adams
(2004) Little Peter, phobia of rabbits
MV, phobia of dogs Autoerotic asphyxiation Martz (2003) Case studies less effective
