Why Do They Do That? Consistent Reinforcement

One of the best explanations for children’s behavioral issues is the concept of reinforcement. All of us have heard about the effects of positive reinforcement or “reward.” We have heard that one of the ways to get children to obey is to give them an immediate reward for specific behaviors. In the opposite way, people think that the way to change or eliminate a behavior is to give a negative reinforcement or a punishment.

The one thing that parents don’t often consider is something we call the “candy aisle phenomenon.”  For psychologists, this is the type of reinforcement that is most important. Here is how it works. A child is in the candy aisle and asks his/her mother for a piece of candy. Mom says, “no.”  In fact, Mom says “no” on every one of the next 5 times that her child asks. So far, so good. Unfortunately, the next time the child asks, the mother gives in. The child has learned to keep up with the questioning for a longer time. This is what we call “intermittent reinforcement.” The behavior in question is reinforced or rewarded sometimes, but sometimes it is not. What happens is that you child has learned to keep trying! After this type of reinforcement, the behavior is very difficult to change. In fact, it is the type of response that is the strongest in prolonging the behavior.

Many parents tell me that they don’t use this type of reinforcement, that it is not a problem for them. What I think happens is that parents don’t notice how frequently they engage in this type of reinforcement. In public, it is often easier to give in rather than have your child melt down, right in the middle of the candy aisle. And, as you have noticed, children do have the capacity to wear you down, even with the best of intentions!

What should a parent do?  First, be careful when you tell a child “no.” You must be really willing to enforce it. If you are not sure, then don’t give a response. This is true of situations that involve both major and minor issues. It is true of items in the candy aisle, of promises to go somewhere (“No, I will not take you to Target”), or of possibilities of major purchases. “No” needs to mean “No.”

So, what if you have told your child “No” but then find out the situation has changed. Can you change your mind?  Of course. But, (and this is an important “but,”) you change your mind because YOU choose to, not because he/she has relentlessly campaigned for it. This may sound like a minor distinction, but it really isn’t. It is quite important. It avoids the intermittent reinforcement (of his/her nagging behavior) and that is key!

Why Do they Do That? It’s Developmentally Appropriate

Often, parents ask me why children engage in certain behaviors.  We have looked at a variety of reasons—because the behavior achieves the intended purpose, because it meets some sensory needs or because it is because it is part of a cycle of behavior that is characteristic of children with Down’s Syndrome.  Are there other reasons?  Yes there are.

One reason that hasn’t been discussed is that the behavior is developmentally appropriate.  If you have ever wondered why your preschooler insists on throwing everything off his/her high chair tray, you will understand the developmental explanation.  Children at his/her age are just learning about object permanency, and he/she is experimenting.  Does a toy that is tossed off the tray continue to exist? When they see it on the floor, it is proof that it continues to exist, It takes a number of repetitions before a toddler can have the principle firmly established.  Unfortunately, the repetitions are usually very unpleasant for adults who are involved!

Similarly, there are many actions that are developmentally appropriate. “No!” from a two-year-old is hardly surprising.  Eye-rolling from a teenager is also developmentally appropriate.  I find that many four year old boys seem to develop a pattern of challenging authority, somewhat like we see in preadolescent males. This is not really “bad” behavior, but is a pattern that does present some challenges to caregivers. These elements of growth are developmental, but can also be difficult.

Children with special needs often show a similar pattern of developmentally appropriate behaviors even though their cognitive profile may not be the same. Some parents are surprised to have their impaired teenagers begin to show typical “push back” behaviors that are characteristic of non-handicapped teens. Disabled two year olds will also develop the “no” stage in spite of their handicapping conditions. Young adults with disabilities do develop a desire to have relationships with the opposite sex and often want to leave home to establish their own independent lives. Sometimes these behaviors are not understood and parents are often unprepared to deal with these “normal” types of behavior.  Interestingly, the types of parental response to these behaviors is usually the same—good limits, appropriate amounts of freedom and lots of teaching of appropriate behavior.
