Thirteen high intelligent (H-IQ) and 13 low intelligent (L-IQ) individuals solved two figural working-memory (WM) tasks and two figural learning tasks while their EEG was recorded. For the WM tasks, only in the theta band group related differences in induced event-related desynchronization/synchronization (ERD/ERS) were observed. L-IQ individuals displayed greater theta synchronization in the later phases of task completion (1000-2000 ms) as compared to H-IQ individuals. For the learning tasks group related differences in the three alpha bands were observed. In the upper alpha band L-IQ individuals showed greater ERD in the frontal brain areas, whereas H-IQ individuals displayed greater ERD in the parieto-occipital brain areas.
13名高智商（H-IQ）个体和13名低智商（L-IQ）个体在解决两项图形工作记忆（WM）任务和两项图形学习任务的同时记录了他们的脑电图。对于工作记忆任务，仅在θ波段观察到组间诱发事件相关去同步化/同步化（ERD/ERS）的差异。与高智商个体相比，低智商个体在任务完成后期（1000-2000毫秒）表现出更大的θ同步化。对于学习任务，观察到三个α波段的组间差异。在α上波段，低智商个体在前脑区域表现出更大的ERD，而高智商个体在顶枕脑区域表现出更大的ERD。
