A schedule of reinforcement refers to the specific pattern and timing according to which reinforcement is delivered following a behavior. Reinforcement is a fundamental concept in learning theory, particularly in operant conditioning, introduced by B. F. Skinner. In operant conditioning, behavior is influenced by its consequences. When a behavior is followed by a reinforcing stimulus, the likelihood of that behavior occurring again increases. The schedule on which reinforcement is provided significantly affects the rate of learning, the strength of the learned behavior, and its resistance to extinction. Reinforcement schedules are broadly classified into two categories: continuous reinforcement and partial (intermittent) reinforcement. In continuous reinforcement, every correct or desired response is reinforced. This schedule is most effective during the initial stages of learning because it helps individuals quickly understand the relationship between behavior and its consequence. For example, a teacher praising a student every time the student answers correctly encourages the student to continue participating. However, behaviors learned through continuous reinforcement are more likely to disappear when reinforcement is no longer provided. Partial or intermittent reinforcement occurs
