Scans suggest IQ scores reflect brain structure

[摘要] Researchers say that a remarkable data set on the developing brain adds to the idea that IQ is a meaningful concept in neuroscience. The study suggests that performance in IQ tests is associated with changes in the brain during adolescence. The research team tracked a group of more than 300 children as they aged from 6 to 19, running them through a series of cognitive tests. IQ is determined by combining scores from tests of a range of verbal and non-verbal abilities.
