Document Summary
Phobic objects = cs for learned fear: generalization to similar stimuli. Why limited range of phobic objects: evolutionary/genetic predisposition. Over the multimillion year of evolution, we came to be prepared genetically to show fear for some objects over others. Better prepared to developed conditioned fear to some stimuli.

Slower to extinguish condition fear to those prepared stimuli (like rats,, snakes, etc. ) than to extinguish fear conditioned to non-prepared regular stimuli (knives, puppies) Hardly anyone who has a fear of snakes had an encounter with snakes. Flooding (implosive therapy: based on extinction via cs-alone presentations. Involves arousal of intense anxiety with cs is present. Can be dangerous for people who have heart conditions for example: stanfil and levis. Tested this model on individuals who had a strong phobia of rats. Test the strength of their fear of rats.
