How to Produce a new response | Shaping (reinforce closer and closer approximations to response we want) |
Operant conditioning | Learning an association between the response and consequences |
schedules of reinforcement | rules that specify when a response will be reinforced |
Fixed Ratio schedule (FR) | Reinforcement is contingent on the last of a fixed number of responses |
Variable Ratio Schedule (VR) | Reinforcement contingent on last of a variable number of responses emitted since last reinforcer. |
Fixed Interval Schedule (FI) | A response is reinforced after a fixed amount of time has elapsed since last reinforcer. |
Variable Interval Schedule (VI) | A response is reinforced after a variable amount of time has elapsed since last reinforcer. |
Differential Reinforcement of Other Behavior (DRO) | A reinforcer is delivered when fixed amount of time has elapsed since last response. |
Fixed Time Schedule (FT) | A reinforcer is delivered when a fixed amount of time has elapsed since last reinforcer. |
Two parts of Law of Effect | Reinforcement and Punishment also extinction |
Reinforcement | If response is followed by favourable consequence it will be more likely to happen again.(presentation of appetitive event or removal of aversive) |
Punishment | If response followed by unfavorable consequence it will be less likely to happen (aversive shown or apetitive removed) |
Extinction | If response used to be followed by reinforcement, but no longer, it will be less likely to happen again. |
Escape | response terminates ongoing aversive event |
Avoidance | response prevents onset of aversive event. |
continuous reinforcement | every response reinforced |
intermittent reinforcement | only some responses reinforced, usually according to schedules of reinforcement |
2 ways of Discrimination Training | Intradimensional 'within' Interdimensional 'between' |
Intradimensional Training | s+ and s- on the same Stimulus Dimension e.g red vs green, 13mm line vs. 9mm line |
Interdimensional training | S= and S- aren't on the same stimulus dimension. (e.g yellow key vs white key w/black vertical line). |
Stimulus Control | The extent to which stimuli that precede or accompany operant behaviour come to affect rate or probability of that behaviour. |
Discrimination | behaving differently in the presence of different stimuli. |
