Question

If reinforcement is delivered after each number of responses listed, which of the following is a variable ratio of 7 (VR7)?

a) Every 7 responses
b) After a random number of responses that averages to 7
c) Every 5 responses
d) After a fixed number of responses

Answer 1

A variable ratio (VR7) reinforcement schedule is one in which reinforcement is delivered after a varying number of responses, with an average of 7. Option b) After a random number of responses that averages to 7 is the correct answer for VR7.

Step-by-step explanation:

A variable ratio (VR7) reinforcement schedule is one in which reinforcement is delivered after a varying number of responses, with an average of 7. Option a) Every 7 responses is a fixed ratio reinforcement schedule, as the number of responses required is constant. Option b) After a random number of responses that averages to 7 is the correct answer for VR7, as the number of responses needed for each reinforcement varies but averages out to 7. Option c) Every 5 responses is another fixed ratio reinforcement schedule. Option d) After a fixed number of responses is a fixed ratio reinforcement schedule as well. In a variable ratio schedule, the unpredictability of when the reinforcement will occur is a key characteristic. This randomness helps to maintain a high and steady rate of responding because individuals are uncertain about when their behavior will be rewarded. This type of reinforcement schedule is often associated with persistent and resistant behavior.
