Document Summary
Flooding (implosive therapy): extinction paradigm, presenting feared object - produce elimination of the fear, based on extinction via cs-alone presentations, presenting cs over and over until fear diminishes. Involves arousal of intense anxiety: become less popular, but still widely used. Systematic desensitization therapy: eliminate conditioned fear without experiencing intentionally. Instead of extinction, use counter conditioning: based on counterconditioning, generalization, eliminate fear to one member of the fear category, and it generalizes to other members of the category, e. g. , fear of heights. Final stage is to experience it first hand. Improves low levels of anxiety: modelling, watching other perform feared actions. Etiology of anxiety: behavioural symptoms, avoidance and escape behaviours, panic disorder, phobias, ritualistic & repetitive behaviours, compulsions in ocd, cognitive symptoms: Intrusive thoughts: obsessions in ocd, recollections in ptsd, strong, persistent fear, psychological processes, response inhibition, ocd, emotion regulation, all anxiety disorders, defence mechanisms, brain structure, function, chemistry, genetic bases.
