Samantha taught her 4-year-old cousin how to do jumping jacks. first, she rewarded him for jumping up and down on the spot. then, she rewarded him for jumping up and down while alternating wide-leg landings with narrow-leg landings. finally, she rewarded him for doing this kind of jumping while also raising his arms from his sides in time to each of his wide-legged jumps. this learning strategy best illustrates the process of:

the process of shaping.

Explanation:

Shaping is the process of establishing a behavior that hasn’t been learned or performed by an individual. Shaping is also  defined as the procedure which involves reinforcing behaviors. Target behavior is also known as successive approximations. This method was developed by Skinner, who is famous for his theories that involve learning behaviors through reinforcement.

The theory of shaping involves reinforcing behavior that are successively closer to the approximations of the desired and targeted behavior.

How vital the process of shaping is says the fact that not always an organism will display the exact target behavior spontaneously. By reinforcing the behavior that is closer to the desired behavior, the required behavior can be taught/learned. Step by step, the procedure of reinforcing different behaviors, the ultimate behavior will be achieved, and it’s called Successive Approximations.
