PS100 Lecture Notes - Lecture 13: B. F. Skinner, Reinforcement, Operant Conditioning
Document Summary
Spontaneous recovery- conditioned stimulus that diminished will pop back up again. Generalization- scared of spiders makes you scared of everything related to it. Discrimination- conditioned response occurs to one stimulus but not to another. Thorndikes law effect- satisfying outcomes increase probability. Chaining- using one conditioned stimulus to train another and make it have the same response. What"s the most efficient schedule?- forward short delay. Variables that affect- interval of time, response dominance (relative strengths of natural response) Pavlov"s- study salivation response in dogs (natural association) Conditioned response- trained to act a certain way (salivating because of bell) Unconditioned response- happens due to stimulus (salivating cause of food) Assumes that behaviours are voluntary, under our control. Primary reinforces: stimuli that are reinforcing because they satisfy biological needs (e. g food, drink) Secondary reinforces: acquire reinforcing properties through association with primary reinforces (e. g money, praise- will only work if its from the right person, someone who has value/ must understand value)
