Abstract
EEGs of four children, ranging in age between 4 and 11 years, were measured to investigate the learning process for a particular capability in the brain. The following points were seen. From the analysis of α waves : (1) Concentrating ability increased with age. (2) For the younger children, concentrating without materials to gaze at seemed to be difficult. From θ waves : (1) Fmθ was sometimes observed. From β waves : (1) Linguistic assignments activated the left hemisphere. (2) Even with frequent visual stimulation, functions of the right hemisphere, such as making a momentary decision or inner visualization, were not presented clearly.
