Schedules of ReinforcementII. Five most common partial reinforcement schedulesa. Fixed ratio schedule (FR-10) b. Variable Ratio schedule of reinforcement (VR-10)c. Fixed interval schedule of reinforcement (FI - 30sec)d. Differential Reinforcement of high rates of responding (DRH)e. Variable interval schedule of reinforcement.Current Lecture I. Schedules of Reinforcement- Rules that specify the relationship between responding and reinforcement. II. 5 typesa. Fixed ratio schedule (FR-10) reinforcement made available after a fixed number of responses. 10x - pellet of food, 10x pellet of food. Fixed ratio produce high rates of responding followed by a post reinforcement pause. b. Variable Ratio schedule of reinforcement (VR-10) reinforcement made available after an average varying number of responses. on average every 10th response. they produce steady responses. steadily responding because it could be the next or the 20th. They are difficult to extinguish. you extinguish them by no longer reinforcing. rat keeps pressing because learned to do it without reward. Ex. gambling behavior. slot machines. once gambling is established it is hard to get rid of. c. Fixed interval schedule of reinforcement (FI - 30sec) - reinforcement made available for the first response after a fixed or set period of time. (FI - 30sec). scalloping is the pattern of behavior associated with responding of fixed interval schedules of reinforcement. ex: in this class 5 week FI schedule of reinforcement. don’t work, cram,expect reinforcement (good grade).d. Differential Reinforcement (DRH) - of high rates of responding you must move behavior from fixed interval to DRH. high rates of responding, ex: studying, med school.e. Variable interval schedule of reinforcement. reinforcement made available after an averaging varying period of time. you get steady responding because nobody knows when it is coming. ex: pop
