Question

i am trying to train my new puppy several new tricks. when he correctly performs a trick, i sometimes give him a treat, and sometimes i dont. this creates a very high rate of correct behaviors. what schedule of reinforcement am i using?
a fixed ratio
b variable ratio
c fixed interval
d variable interval

Explanation:

To determine the reinforcement schedule, we analyze each option:

• Fixed ratio: Reinforcement after a fixed number of responses (e.g., every 3 tricks). The scenario does not mention a fixed number.
• Variable ratio: Reinforcement after a variable number of responses (e.g., sometimes after 1 trick, sometimes after 3). The puppy gets treats "sometimes" for correct tricks, matching variable responses.
• Fixed interval: Reinforcement after a fixed time (e.g., every 5 minutes). The scenario focuses on responses (tricks), not time.
• Variable interval: Reinforcement after variable time intervals (e.g., sometimes after 2 minutes, sometimes after 10). The scenario is about responses, not time.

The key is that the treat is given for a variable number of correct responses (tricks), which matches the variable ratio schedule.

Answer:

B. Variable ratio
