Question

when we train a dog to roll over, we successively reward behaviors that are closer and closer to the final activity we want to see. which of the following describes this procedure?
o successive approximations
o shaping
o partial reinforcement
o variable reinforcement

Explanation:

Shaping is a behavior - modification technique in which successive approximations of a desired behavior are reinforced. In the case of training a dog to roll over, each behavior that gets closer to the final "roll - over" (successive approximations) is rewarded. Partial reinforcement (reinforcing only some of the behaviors) and variable reinforcement (reinforcing on a variable schedule) do not specifically describe the process of rewarding closer and closer behaviors. While successive approximations are part of the shaping process, the term "shaping" is the over - arching procedure that encompasses rewarding successive approximations.

Answer:

shaping
