Question

Which schedule of reinforcement provides a reward after a random number of responses?

• A. Fixed Ratio (FR)
• B. Variable Ratio (VR)
• C. Fixed Interval (FI)
• D. Variable Interval (VI)

Answer 1

Answer:

B. Variable Ratio (VR)

A variable ratio (VR) schedule of reinforcement provides a reward after a random number of responses. This schedule is highly effective in maintaining behavior because the unpredictability of the reward keeps the individual engaged. A common example is a slot machine, where payouts occur after a random number of plays, making it highly addictive. In contrast, fixed ratio schedules provide rewards after a set number of responses, while interval schedules provide rewards after a certain period of time.
