Bulimia Nervosa
• Operant conditioning– Binge eating make the person feel better
when anxious/depressed– But this leads to anxiety about feeling full– Purging reduces anxiety about feeling full– In both cases, negative reinforcement
• Social learning– Not a major role, but might play a part
e.g. in dancing schools where BN is prevalent
