What term refers to the rules that determine when and how reinforcements are delivered?

• A. Schedules of Reinforcement
• B. Punishment
• C. Shaping
• D. Extinction

Answer: (A)

Schedules of reinforcement are the rules that determine when and how reinforcements are delivered. These schedules specify the pattern and timing of reinforcement, shaping how a behavior is repeated. For example, a fixed-ratio schedule reinforces after a set number of responses, prompting rapid responding with a brief pause after each reward; a variable-ratio schedule reinforces after an unpredictable number of responses, producing high and steady response rates; a fixed-interval schedule reinforces after a fixed amount of time, often causing a surge in responding as the time for reinforcement approaches; a variable-interval schedule delivers reinforcement at unpredictable times, leading to a steady but moderate rate of responding. This framework explains why different reinforcement patterns produce different behavior, persistence, and response shapes. The other terms describe related ideas but not the pattern of reinforcement delivery: punishment aims to decrease behavior, shaping is about reinforcing closer approximations to a target behavior, and extinction is the stopping of reinforcement that leads to a decrease in a behavior.
