If environment didn't play a part in determining an individual's traits and behaviors, then identical twins should, theoretically, be exactly the same in all respects, even if reared apart. But a number of studies show that they are never exactly alike, even though they are remarkably similar in most respects. (Powell, 2013)
In operant conditioning, when you reward a behavior, chances are that same behavior is likely to occur again in the future. When a behavior is punished, it becomes less likely that it will occur again in the future. These principles underlie the concept of operant conditioning, a set of learning techniques that utilizes reinforcement and punishment to either increase or decrease a response. For example, when a child is rewarded for cleaning her room, she becomes more likely to repeat the same behavior later on. (Cherry, 2012)
The nurture theory holds that genetic influence over abstract traits may exist; however, the environmental factors are the real origins of our behavior. This includes the use of conditioning in order to induce a new behavior to a child, or alter an unlikely behavior being shown by the child. According to John Watson, one of the strongest psychologists who propose environmental learning as a dominating side in the nature vs nurture debate, once said that he can be able to train a baby randomly chosen in a group of 12 infants, to become any type of specialist Watson wants. He stated that he could train him to be such regardless of the child's potentialities, talents and race. (Sincero, 2012)
True, there is a shared environment. Siblings may have the same parents, live in the same home, eat the same meals, attend the
