Question

Al must build 25 radios before he receives $20. What schedule of reinforcement is being used?

a variable-ratio schedule

a continuous schedule

a fixed-ratio schedule

a fixed-interval schedule

a partial-interval schedule

Answer 1

This is called a FIXED RATIO schedule of reinforcement.

What this means is that a reward is given,
after an EXACT NUMBER of actions.

In this case,
Al gets his reward ($20)
after he builds EXACTLY 25 radios.

Does that make sense?
