Document Summary
Fixed- reinforcement after a given amount of time or responses. Variable- on average, you get reinforcement after a given amount of time or responses, but the exact reinforcement is random. Ratio- based on number of behaviors (i. e. ratio of responses to reinforcements) Fixed ratio- reward after a certain number of behaviors (e. g. earning a bonus for every 5 cars sold) Variable ratio- reward after a random number of behaviors (e. g. slot machines) Fixed interval- reward after a certain amount of time (e. g. paycheck every 2 weeks) Variable interval- reward after a random amount of time (e. g. receiving an email or message response) With ratio schedules the more you press it the more you will get your food. Dashes are places where reinforcements are actually happening. They produce more rapid responding than intervals. Variable ratio is most resistant to extinction. Intermittent is only reinforcing sometimes; giving dog a treat for doing something. You coach someone into doing a complex behavior.
