The correct answers are extinction; operant.
Answer 1: Extinction refers to the process in which a previously reinforced or learned behavior stops occurring when the behavior is no longer reinforced. For instance, if you previously rewarded your dog for giving you a high five and then gradually stopped rewarding your dog for giving you a high five, your dog will likely stop giving you high fives.
Answer 2: Operant conditioning refers to learning technique in which learning takes place due to outcomes of either rewards or punishment. For instance, if a child is rewarded with candy each time he helps set the dining table, he will learn that setting the dining table is a positive behavior and will continue doing so.
