Answer:
Shaping
Step-by-step explanation:
Behavioral shaping was first developed and carried out by B.F Skinner. It involves using reward to reinforce desired behavior. The reinforcement is continuously carried out through the use of reward as the person gets closer and closer to the desired behavior. For example the mother of Ajay gradually increased the amount of time Ajay played quietly and she only reinforced with reward as Ajay kept the desire time ( 10 minutes, 20 minutes) She did not reinforce the previous 10 minute but the 20 minutes and only reinforced after the half hour set on Wednesday. After the final desire has been achieved, she will reinforce the final response.
