The brains of adolescents react more responsively to receiving rewards. This can lead to risky behaviour, but, according to Leiden University research, it also has a positive function: it makes learning easier.
Alcohol abuse, reckless behaviour and poor choice in friends: all these are inextricably linked to puberty and adolescence. In the late teens, young people test their limits, and in many cases, push beyond their limits. This is due in part to increased activity in the corpus striatum, a small area deeply hidden away inside the brain. According to previous research, that part of the brain in young people is more responsive to receiving rewards.
Sensitive
Leiden University scientists are now able to show that this increased activity in the corpus striatum does not have only negative consequences. 'The adolescent brain is very sensitive to feedback,' says Sabine Peters, assistant professor of developmental and educational psychology and lead author of the article. 'That makes adolescence the ideal time to acquire and retain new information.'
Peters used a large data set for her research with MRI scans. Over a period of five years, no fewer than 736 brain scans were made of a total of 300 subjects between the ages of 8 and 29. According to Peters, the data set is about ten times larger than that of most comparable studies. In the MRI scanner, participants had to solve a memory game. During that game, the researchers gave feedback on the participants' performance. Read more...
