Document Summary
The s is the variable before the response and reinforcement that indicates that a contingency will not occur (s ---> response --x--> reinforcement) Ex. child gets rewarded w/ a dessert if he eats his vegetables. (sd is the environment; his parents house/ s would be his grandparents house, where this contingency would not happen) Sarah learned a contingency between polite behaviour and reward. She will be polite with other authoritative figures around but not as much, and her politeness will decrease with different kinds of people around her. Sarah"s parents don"t pay enough attention to sarah"s polite behaviour, this might lead to extinction of the contingency. Ex. the authority figures sarah usually is polite around begin to not notice her polite behaviour, this might lead to sarah restricting her polite behaviour to her parents (original sd) In a lab, experimenters can manipulate variables: sd, s , and presentation of reinforcers.
