Study Reveals Why Kids and Teens Turn Egocentric Rather Than Introspective
Neuroscientists at Georgetown University Medical Center have shown why children and young adolescents veer toward the egocentric rather than the introspective.
In findings the researchers say that the five scattered regions in the brain that make up the default-mode network (DMN) have not started working in concert in youngsters aged six to nine. These areas light up in an fMRI scan, but not simultaneously.
The DMN is only active when the mind is at rest and allowed to wander or daydream. This network is believed to be key in how a person introspectively understands themselves and others, and forms beliefs, intentions, and desires through autobiographical memory.
By ages 10 to 12, the researchers found that these diffuse regions start functioning together as a unit, and at ages 13 to19, they acted in concert, just like they do in adults.
"These results suggest that children develop introspection over time as their brains develop," said the study's first author, neuroscientist Stuart Washington, who will be presenting the results.
