Document Summary
Increase probability of behaviour: 2 ways to reinforce behaviour. Decrease probability of behaviour: 2 ways to prevent behaviour: positive reinforcement/pleasant stimulus doesn"t have to be reward. E. g. , emailing a professor get quick response increase frequency of emailing: extinction: knocking on office door no one responds reduce knocking. Increase behaviour add good stimulus (positive reinforcement), or take away bad stimulus (negative reinforcement: decrease behaviour take away good stimulus (extinction) , or add bad stimulus (punishment) Reinforcement is the process by which stimuli strengthen behaviours. I want a quiet dog: positive reinforcement, he gets a treat if he waits at the door quietly, add pleasant stimulus, negative reinforcement, tied up until he is quiet, remove unpleasant stimulus, note: not punishment. Punishment vs negative reinforcement: punishment follows an undesired behavior it reduces the occurrence of the undesired behavior, negative reinforcement involves removing an unpleasant stimulus when a. Desired behavior occurs it increases the occurrence of the desired behavior.
