Edf 6221 Test 2 Questions & Correct Answers

Fixed ratio (FR) {Ans: The same amount of reinforcement is delivered based on number of responses. Report in responses (ex. FR3). Post reinforcement pause. Good for building new responses. Fixed schedule allows for more fine grain manipulation than interval}Shaping behaviors refers to the reinforcement of ___ ___ of a terminal behavior {Ans: successive approximations}Thinning reinforcement {Ans: 1. Gradually increase responding requirement 2. Provide directions or rules regarding reinforcement}Shifting criterion {Ans: The gradual increase of the criterion for reinforcement. Sometimes called changing criterion}Behavioral chaining {Ans: Reinforcing responses when they occur in a sequence so that they form a complex behavior. Help strengthen new behaviors and weaken maladaptive ones.}Fixed interval (FI) {Ans: The same amount of time elapses when the reinforcement is delivered. Report the unit of time in schedule (ex. FI 2 minutes). Post reinforcement pause will occur. Responses increase closer to the interval. Overall slow to moderate effects on behavior}Variable Interval (VI) {Ans: An average of unit of time. Report as either median or mean (median with outliers) (ex: 1, 2, 3, 4, 5 seconds = VI 3 seconds). Unlikely to see a post reinforcement pause. Will keep a moderate rate of responding
