Document Summary
Ps101 - lecture 22 - treatment of psychological disorders part 4. Maladaptive behaviours are the problem, not a symptom. Maladaptive behaviours can be unlearned through classical and operant conditioning, modeling. Phobias - exposure to feared cs in the absence of ucs. Flooding: real exposure; flooded with real life stimuli. Systematic desensitization: eliminate anxiety through counterconditioning (ex. Implosion: like flooding, but imaginative scenes spider and relaxation); steps: Condition an aversion to a cs (ex alcoholic drink) Use positive reinforcement, extinction, negative reinforcement, punishment (least desirable option) Successful when traditional therapies are difficult to implement. Learning skills by observing and imitating a model who performs a socially skillful behaviour. Study how drugs affect cognitions, emotions, behaviour. B) available neurotransmitters will cross the synaptic cleft: reuptake can occur. Norepinephrine - mood based (attention, motivation, pleasure, reward) Serotonin - mood and anxiety based (obsessions/compulsions) Dopamine - mood and anxiety based (alertness, energy) Prevent reuptake: monoamine oxidase (mao) inhibitors.
