PS261 Chapter Notes - Chapter 3: Corneal Reflex, Conditioned Taste Aversion, Fear Conditioning
Document Summary
If human and nonhuman animals only had the behavioural mechanisms described in chapter 2, they would remain rather limited in the things that they could do. Habituation and sensitization involve learning about just one stimulus, but events in the world do not occur in isolation. Cause and effect relationships in the world ensure that certain things occur in combination with others. The simplest mechanism whereby organisms learn about the relations between one event and another is classical conditioning. Systematic studies of classical conditioning began with ivan pavlov, and was also discovered by edwin. Pavlov"s classical conditionings were an extension to his work with digestion in dogs; found that stomach secretions occurred when the dogs saw the people feeding them or even the sight of food. Stomach secretions elicited by food-related stimuli were referred to as psychic secretions because they seemed to be a response to the expectation or thought of food.
