Answer: Fixed Ratio.
Explanation:
Operant conditioning refers to the strengthening or weakening of specific behaviors through a set of rewards and punishments.
A fixed-ratio schedule of reinforcement involves the reinforcement of a response after a fixed number of responses. The trainer rewards the subject if a set number of responses are provided.
This kind of schedule of reinforcement allows a high and steady rate of responding with solely a short pause following the reinforcement.
