Not unlike our adolescents’ changing body shape, different regions of the brain mature at different times and the prefrontal cortex, which has been likened to the brain police, does not fully develop until early twenties. This region of the brain checks all the information coming from other parts of the brain before releasing it. For instance, we might read something which will arouse a murderous rage in us, but the prefrontal cortex will come along and tell that part of the brain to ‘quieten down’.
As Karl Pibrab, the director of Brain Research and Informational Sciences at Radford University in Virginia, puts it, ‘The prefrontal cortex is the seat of civilization.’
So until the prefrontal cortex is fully developed, most teenagers don’t have the ability to make good judgements, control their emotions, prioritize, or multi-task, as in make the right decision between watching TV, ringing a friend, doing a chore they’ve been asked to do or finishing their homework. This means that they do not intentionally do the wrong thing just to wind parents up. As Richard Restak, a neuropsychiatrist and author of The Secret Life of the Brain said, ‘The teenage brain is a work in progress that we’re only beginning to understand.’ (So what chance do we have?!)
Work by Marvin Zuckerman, a professor of psychology, has found that new experiences, especially those with an element of risk, tap into a part of the teenager’s brain which links with emotional centres that produce feelings of intense pleasure. Add to that the research which shows that during adolescence, the temporary decline in the production of serotonin in their brain will probably make
‘It’s not my fault I haven’t done my English, washed up or let the dog out – it’s my under-developed prefrontal cortex!’
them act more impulsively, and you may begin to realize why our adolescents might still jump into a car with a friend who’s had a drink despite our warnings.
Finally, findings of Francine Benes, a neuroscientist, show that one of the last developments of the adult brain is the nerve coating called myelin, which acts like the insulation on an electric cord, allowing electrical impulses to travel down a nerve quicker and more efficiently. That is why a toddler is less co-ordinated than a ten year old. But this process may not be complete until their early twenties. Some of these nerves that become sheathed during adolescence connect regions of the brain that control emotion, judgement and impulse control. This happens earlier in girls than boys, which probably explains why girls are more emotionally mature than boys, whose myelin levels may not reach the same level until the age of thirty. (Thirty? Surely scientists mean seventy!)
Healthy Sources of Stimulation
Trying new experiences is a normal and healthy part of growing up, and as parents we need to try and encourage fairly safe sources of stimulation. Where one child may find it in a drama production at school, another will prefer the excitement of a BMX trick bike, and some children will be lucky enough to go skiing, or diving. Unfortunately, many children don’t have the option or encouragement to find a sport or interest to stimulate them, and resort to crime or drugs.
So try and encourage your teenagers to take up new interests if they don’t already have any.
The good news is that if all this scientific research is proven over a length of time, even very troubled teenagers can still learn good judgement and restraint.
Anyway, even if all this scientific research is absolutely correct, it’s best we don’t let our teenagers know, otherwise every time we ask them why they haven’t done their homework or cleared the dishes, they’ll reply, ‘But it’s not my fault, mum, it’s my under-developed prefrontal cortex!’
Where does it all go wrong?
No teenagers are perfect, and to be honest if you had a fifteen-year-old daughter who sat at home every evening wearing the sensible clothes you had chosen, never rang or went out with her friends, agreed with your every opinion, never experimented with her hair and make-up, only listened to your music and kept her room perfect, would you be deliriously happy or seriously worried? Believe me, you should be seriously worried.
Adolescents are at the crossroads between being an adult and a child and it is highly frustrating for them (and you). It is a time when they realize they can be independent from their parents yet still need their guidance, love and support, not that they’ll ever consciously accept that fact. All teenagers want to be adults but don’t have the maturity to master adult behaviour. They will often act childishly yet take umbrage if treated like one. And teenagers positively luxuriate in a world of non-responsibility; they can sit in front of a TV all day without a care in the world, make themselves sandwiches and leave the bread, filling and plates all over the kitchen.
Adolescence is a time of experimentation, and difficulties arise when parents lose the balance between allowing their teenagers to experience their new independence whilst still setting boundaries.
Trusting your teenagers is the key to their self-respect and respect of you. Most conflicts between parents and teenagers will stem from small, simple matters, such as getting in late, school work, untidy bedrooms and not helping around the house; all issues which can be settled with negotiation and compromise. Teenagers only rebel when they have something to rebel against.
Parents simply cannot parent teenagers the same way they necessarily parented them as children; their behaviour must change if they want to change their teenager’s behaviour.
For the past twelve years parents have guided and nurtured their children and now they have to step back in some areas. Although we are still there for love and support we must let our children learn new life skills, so we have to stop being over-protective or over-guiding in coping with every day problems. But teenagers still need boundaries as adolescence is a very confusing time and knowing their limits is comforting, although they may well occasionally cross them. Teenagers who are not given boundaries will be unhappy and feel depressed, although outwardly they would argue otherwise.
Many parents find it difficult to understand that, just because their adolescents choose to spend more time with their friends than they do with their family, they don’t love them any less. They will love and respect us far more for accepting they are now independent of constant parental supervision and given more responsibility to prove it. Parents also find it difficult to adjust to the emotional distance some teenagers put between them, but again this is not because their love for their parents has changed, they are in their own way weaning themselves off us. Teenagers still seek their parents’ approval and if parents are constantly criticizing them they will seek approval elsewhere. Adolescents will not turn to parents who constantly say, ‘No,’ routinely judge, order, criticize or are not open to negotiation.
There will be times when your frustration and anger boil over, your heart rate shoots up and you want to shout and scream and even shake or hit them. ‘How could they have done that?’ ‘Why don’t they ever do as they are asked?’ ‘Why don’t they ever think of anyone but themselves?’ ‘Why do they have to leave such a bloody mess everywhere?’ Overload can be sparked by the smallest issue, even a look or a shrug. First, it’s normal to feel like this, you’re a parent not Francis of Assisi. You have your own anxieties and stress from other parts of your life which will obviously overflow into how you deal with your teenagers on some days. When you get to overload, lock yourself in your bedroom, lie on the bed or go outside and take a five minute break. Take some deep breaths, look at a few photos of your teens when they were young children and smile, hard as this may seem. You might even have a good cry with the frustration of it all – well don’t worry, you’re not alone, we all feel like that sometimes. And don’t feel guilty that you felt so mad you wanted to become physical; it was just anger. But it is much better to get yourself back under control before you tackle them over an issue. You can always resort to honesty, ‘Come here and give me a hug to remind me why I love you, otherwise I may have to kill you.’
