Which type of schedule consists of alternating schedules associated with different stimuli?

The correct answer is found in the concept of schedules of reinforcement. A multiple schedule is defined as a type of schedule that consists of two or more independent schedules of reinforcement that occur in alternating succession. Each schedule is associated with a specific stimulus, allowing the individual to understand which type of reinforcement is available. This setup enables the practitioner to evaluate the responses under different conditions, making it useful for understanding behavior in various contexts.

In a multiple schedule, the key feature is that the stimuli signaling the different schedules are present, so the individual can discriminate between them. This aids in teaching behaviors more effectively, as the subject learns to respond differently based on the cues presented.

Options that involve concurrent schedules, chained schedules, and mixed schedules differ in structure and purpose. In a concurrent schedule, multiple reinforcement options are available simultaneously, but they do not have the alternating structure with distinct cues like in a multiple schedule. A chained schedule involves a series of linked responses where each step must be completed in order to receive reinforcement, without alternation of stimuli. Mixed schedules also lack the clear signals associated with different schedules, creating a situation where reinforcement is delivered without any indication of which schedule is in effect at any moment. Thus, the characteristics and applications of multiple schedules distinctly highlight their importance
