Answer:
The correct answer is C.
Explanation:
Techniques for establishing new behaviors are shaping (successive approximations), chaining, and fading. Shaping is the establishment of a final behavior (one that the person does not possess or that very rarely emits) through the differential reinforcement of behaviors that are increasingly similar or close to it. Generally, shaping refers to differential reinforcement of changes gradual changes in the topography of a behavior, but it can also refer to differential reinforcement of gradual changes in other characteristics of the behavior such as frequency, duration, latency or magnitude, or differential reinforcement of gradual changes in the product of the behavior (for example , number of exercises solved).
