Teen Brains Wired to Make Lousy Decisions [Guest Post]
Posted May 24 2009 10:13pm
Ever scratch your head and wonder what your teen was thinking when they made a decision that was clearly going to have negative consequences? You saw the right choice; why couldn’t they?
Two reasons: teen brains aren’t fully grown up, and teens use a different part of the brain to make decisions than you do.
Get used to scratching your head for a few more years. Your teen’s “good decision making” part of the brain won’t mature until they are in their late twenties. This slow growing part of the brain is called the prefrontal cortex. Think of it as the CEO of the brain. It is responsible for rational, logical decision making, future planning and understanding consequences. Since this part of the brain is still maturing, teen brains’ are wired to rely more another area of the brain to make decisions. It’s called the limbic system.
The limbic system is the part of the brain that is responsible for what scientists call the 4 F’s: feeding, fighting, fleeing and sexual reproduction. (You can fill in that F.) The 4 F’s are all about survival, pleasure in the moment, and emotions. The limbic system is fabulous to help your teen run away from or fight off danger, but lousy at helping them decide if sneaking out of the house in the middle of the night with their buddies is a stellar move.
It is important for parents to understand the teen brain so they don’t flip out when their teen makes lousy decisions Parents should use those lousy decisions as teachable moments rather than shame their teen and scream, “What were you thinking?” The fact of the matter is they probably weren’t thinking. At least not like an adult would think. With the limbic system as the “steering wheel” for teens, sneaking out in the middle of the night feels like a fine choice when it is suggested.
One way to help your teen learn to connect more with their prefrontal cortex is to ask your teen to think through consequences of actions before they are presented with the situation. Let them “role play.” You may need to list possible outcomes of decisions so they have a better understanding of what might happen. The key is to present the information in a neutral way and allow your teen to have as much control over their choices as possible . If you always make your teen’s decisions, they won’t have the chance to figure out their own lives. Some research suggests that teens who take some risks and don’t get hurt by them, actually grow up to be more successful than teens who don’t take some risks. That’s not to say you want your teen making lousy decisions all the time. But look on the bright side. They are growing and learning, one lousy decision at a time.
