The study compared the performance and brain activity of children who were intellectually gifted or of average intelligence. 13 intellectually gifted (4 girls, 9 boys; M age = 12.0 yr., SD = 0.2) and 13 average children (5 girls, 8 boys; M age = 11.9 yr., SD = 0.3) participated in a task-switching experiment. The children performed a task repeatedly (single-trial blocks) or switched between two different tasks (mixed-trial blocks). Intellectually gifted children performed quicker than the average group for both mixed and single-trial blocks. The electroencephalography P300 amplitude was larger in the mixed compared to the single-trial condition, but this effect was observed only in the gifted children. The results support the notion that gifted children are characterized by a faster maturation that leads to an ‘adultlike’ brain activity.
