Final answer:
The correct answer is A) Tandem schedule because it is the same as a multiple schedule but without discriminative stimuli.
Step-by-step explanation:
The correct answer is A) Tandem schedule because it is the same as a multiple schedule without discriminative stimuli. In a multiple schedule, different discriminative stimuli are used to signal different reinforcement schedules. However, in a tandem schedule, there are no discriminative stimuli to signal the schedules.
For example, in a multiple schedule, a red light might signal a fixed ratio schedule and a green light might signal a variable ratio schedule. In a tandem schedule, the behavior is reinforced without any specific cues or stimuli.
So, in this case, a tandem schedule is the same as a multiple schedule but without discriminative stimuli.
