Final answer:
A mixed schedule of reinforcement alternates between two or more basic reinforcement schedules in a random sequence. Examples include variable ratio and fixed ratio reinforcement schedules that depend on an unpredictable or predictable number of responses, and fixed and variable interval schedules that depend on a set or varying amount of time, respectively.
Step-by-step explanation:
The compound schedule you're referring to is known as a mixed schedule of reinforcement. It's a procedure in operant conditioning where two or more basic schedules of reinforcement operate alternatively and randomly. For instance, a variable ratio reinforcement schedule rewards behavior after an unpredictable number of responses. This results in a high and steady rate of response since the subject doesn't know when the next reinforcement is coming. This unpredictability is similar to a gambler's behavior while playing a slot machine; each spin is a new chance for a reward.
Another schedule is the fixed ratio reinforcement schedule, which delivers reinforcement after a predictable number of responses have been made. This predictability can result in a high rate of response with a brief pause after the reinforcement is delivered.
Additionally, a fixed interval reinforcement schedule offers reinforcement after a predetermined amount of time has passed. This can lead to a scallop-shaped pattern of responding due to a post-reinforcement pause. Lastly, with a variable interval reinforcement schedule, reinforcement comes at varying and unpredictable time intervals, which maintains a moderate, steady rate of response.
