Part 1a: Describe an original example of a 3-term contingency. Could you be sure to give adequate detail in explaining each term (antecedent, behavior, reinforcer)?

Part 1b: Using THE SAME example from 1a, expand the contingency from 3 to 4-terms. Then explain how doing so enhances the example and may lead to more effective intervention.

This only needs no more than five sentences.
