Document Summary

Physiological, and subconscious responses, no conscious control over actions. Innate responses, like drooling/salivating, birds being responsive to visual stimuli, no exp. Complex collections of neurons processing different stimuli. Trained rats to press level for food. Separates rats into groups, when tone doesn"t play, we"re also going to shock the rats, random punishment (some groups got shocked during silence between shocks) Some rats learn there is no difference between tone periods and non-tone periods because of random shocking. Some rats realize that tone is responsible of shock. Suppression ratio - ratio between rat"s activity in condition period and non-condition period (tone period when shocked and relationship to suppression activity, and rate of fore-conditioning, how likely were they to suppress before any conditioning) There is a direct relationship between how predictable the suppression is, and the shock. Classical conditioning, predictable behavior may be helpful, while in operant conditioning, it may cause more confusing than anything else.
