Final answer:
Jarren's method of training his dog to play dead by rewarding incremental steps toward the final desired behavior is a classic instance of shaping, a technique used in operant conditioning.
Step-by-step explanation:
Jarren training his dog to play dead through a series of smaller steps, such as giving a treat each time the dog crouches down, is an example of shaping. This technique involves reinforcing successive approximations of a target behavior. In shaping, it is highly effective to use positive reinforcement, adding a desirable stimulus, like a treat, to increase the likelihood of the behavior occurring again. Shaping allows an individual to learn complex behaviors that they are unlikely to exhibit spontaneously, by breaking the behavior down into achievable steps and rewarding each of them.
