N. Jausovec, DIFFERENCES IN EEG ALPHA-ACTIVITY BETWEEN GIFTED AND NON-IDENTIFIED INDIVIDUALS - INSIGHTS INTO PROBLEM-SOLVING, The Gifted child quarterly, 41(1), 1997, pp. 26-32
The study investigated differences in electroencephalography (EEG) alp
ha activity between gifted and non-identified students. Seventeen gift
ed and 17 non-identified students. participated in the experiment. The
ir EEG was recorded while they solved four problems. Two measures were
used: 1) an asymmetry index or differences in hemispheric activity an
d 2) the overall difference between a relaxed mental state and problem
solving. The findings can be summarized as follows: First, gifted stu
dents in a relaxed mental condition showed greater left hemispheric ac
tivation than did non-identified students. In contrast, during problem
,solving, non-identified students showed greater left hemispheric acti
vity than did gifted students. Second, gifted students exhibited a hig
her overall hemispheric activation in a relaxed mental state and explo
ring the problem, and a lower activation when problem solving was invo
lved, than did non-identified students.
