PS102 Lecture Notes - Lecture 1: Operant Conditioning, Classical Conditioning, Observational Learning
Document Summary
Learning - change in behaviour due to experience. Conditioning - association between environmental stimuli & the organism"s response. Could create any type of profession out of one person. Not just a change in behaviour, a change in knowledge. Unconditional stimulus- a stimulus that naturally triggers a response (also known as neutral) Conditioned stimulus- a stimulus introduced to trigger a response. Unconditioned stimulus (us) + conditioned response (cr) --------- Food (us) + bell (cr) ---- drool (ur) A previous neutral stimulus produces a response through association with a stimulus already associated with a response. Neutral or unconditioned stimulus must occur before the conditioned response. Extinction - weakening to eventual disappearance of a learned response. Higher order conditioning - react to a new stimulus. Stimulus discrimination - respond differently to two or more stimulus. Objects associated w/ positive feelings = learning to like. Fear can be learned through association ie. john watson little albert study.
