What type of reinforcement occurs when only some responses receive reinforcement?

The concept of intermittent reinforcement refers to a schedule of reinforcement in which only some of the desired responses are followed by reinforcement. This approach contrasts with continuous reinforcement, where every correct response is reinforced. Intermittent reinforcement can strengthen a behavior over time, making it more resistant to extinction. It creates a situation in which the individual is unsure when the next reinforcement will occur, often leading to higher rates of response.

This type of reinforcement is commonly observed in various training and behavioral modification settings, as it can maintain behavior more effectively in the long term. The unpredictability of reinforcement can encourage persistence in engaging with a task or behavior, as the individual learns that while not every attempt will produce a reward, there is still a chance of reinforcement with repeated efforts.
