Question

dr. arceneaux has developed several alternative plans to increase the number of online practice quizzes students complete. which plan below is incorrectly matched with the reinforcement schedule?

one bonus point for every two online practice quizzes completed—fixed - ratio

one bonus point awarded every two weeks if two or more quizzes have been completed—fixed - interval

all of the available are correctly matched.
one bonus point awarded every two weeks on average if two or more quizzes have been completed recently—variable - ratio

Explanation:

In operant - conditioning, a fixed - ratio schedule rewards after a fixed number of responses. One bonus point for every two quizzes is fixed - ratio. A fixed - interval schedule rewards after a fixed time period if the behavior occurs. One bonus point every two weeks if two or more quizzes are completed is fixed - interval. A variable - ratio schedule rewards after a variable number of responses, and a variable - interval schedule rewards after a variable time period. The statement "one bonus point awarded every two weeks on average if two or more quizzes have been completed recently" is a variable - interval, not variable - ratio.

Answer:

one bonus point awarded every two weeks on average if two or more quizzes have been completed recently—variable - ratio
