apter 6 16) Your roommate is taking a self-paced course that requires three papeier three finish all three papers in the first two weeks but, after quickly finishing t has done nothing. This behavior pattern is due to over the semester. He expected to he first paper three weeks ago, he a. the partial reinforcement extinction effect b. the post-reinforcement pause. c. the variable ratio schedule of reinforcement d. the variable interval schedule of reinforcement. 17) For 30 ten-minute trials, a rat received a food pellet every other lever press. reinforcement schedule of This rat was on a a. fixed interval b. fixed ratio c. variable interval d. variable ratio 18) If a ratio requirement is increased from an FR 100 schedule to an FR 500 schedule, the subject will ofen pause periodiceally before completion of the ratio requirement. These pouses are due to a. the post-reinforcement pause b. the ratio strain. c. the ratio run. d. the interval scallop. pigeon in a Skinner box periodically receives access to food after pecking on a key. Sometimes the pigeon has to peck 3 or 4 times, sometimes 5, and sometime more. On average, the bird was reinforced every 5th peck. Thi s pigeon was on a schedule of reinforcement. a. fixed interval b. fixed ratio c. variable interval d. variable ratio 20) You notice that the pigeon in the laboratory you just entered has a particular way of pecking at the key in its cage. The pigeon seems to increase its rate of pecking towards the end of a two-minute period, food is made available, and then pecking slows until the end of the next two minutes. You surmise that the pigeon is on a a. fixed ratio schedule. b. variable ratio schedule. c. fixed interval schedule d. variable interval schedule. 21) A cumulative recorder marks a scalloped patten of responding when subjects are on a: a. fixed ratio schedule. b. fixed interval schedule. c. variable ratio schedule. d. variable interval schedule. 22) Your friend is taking a class with exams scheduled every three weeks. You expect that he will study: a. at a high steady rate throughout the semester b. at a rapid and steady rate once he gets started, followed by periods of no studying. c. very little following an exam but with increasing rates at the end of the three weeks d. at a low steady rate throughout the semesterExplanation / Answer
Note: This response is in UK English, please paste the response to MS Word and you should be able to spot discrepancies easily.
(Answer) (1) (B) The post-reinforcement pause – because after high reinforcement and completion of the task, the reinforcement has stopped and he does not respond to the roommate’s beckoning.
(2) (A) Fixed Interval. The rats are offered reinforcement with each alternate lever press. This is a fixed quantity with a steady ratio of rewards.
(3) (A) The case has all the signs of a post-reinforcement pause
(4) (D) Variable Ratio. Because the pigeons were consistently reinforcing for a reward that appeared at varying periods.
(5) (C) Fixed interval schedule - follows the typical pattern of low rate responses to high rate responses at fixed intervals.
(6) (B) Fixed interval schedule has the main characteristic of graphs appearing in a scalloped pattern.
(7) (C) Because I am applying the fixed interval schedule to surmise his behavioural patterns.
