PSYC 198 Lecture Notes - Lecture 4: Sensory Memory, Operant Conditioning Chamber, Alarm Clock
Document Summary
Learning: a change in thought or behavior resulting from experience: stimulus: anything in the environment to which an organism might react, response: any behavior resulting from a stimulus. Behaviorism: focused on observable changes in behavior; disregarded everything else (like emotions, thoughts, etc. : stimulus (internal thought process in mind was disregarded) response. Classical conditioning (ivan pavlov): learning associations between stimuli. Ivan pavlov studied digestion and discovered classical conditioning on accident: dogs salivated when they saw meat. Then paired meat with the sound of a metronome. At first, nothing happens when hearing the tone.

Unconditioned response is the milk production (milk let down). Conditioned response is milk production from the baby crying: going to the dentist could cause anxiety/pain. Learn to pair the sound of drilling with the unpleasant experience of being at the dentist.
