Problem: The four-term contingency is an expansion of the classic three-term contingency (Antecedent → Behavior → Consequence) by adding motivating operations (MO). At Morningside, instruction is carefully arranged so that: Motivating Operation (MO): The student is in a state that makes learning or the skill desirable. Discriminative Stimulus (SD): Clear cues signal the opportunity to respond. Response (R): The student emits the correct behavior. Consequence (C): Immediate, specific feedback reinforces learning. Morningside teachers use this framework to ensure that every skill is taught in a context where reinforcement is meaningful and learning is highly likely. Reword and add to it. Need Assignment Help?
