Abstract
A distinct theta rhythm of EEG in the frontal midline area during performance of mental tasks has been called Fm theta. One of the characteristics of Fm theta is individual differences in its appearance. The effects of various mental tasks and its repetition on appearance of Fm theta were investigated. Adding, correcting wrong words, short-term memory (STM) and counting cubes were imposed 6 times on 7 male students who didn't generate Fm theta at the previous experiment. Counting cubes evoked more Fm theta than the other three mental tasks. In every task the first trial showed little Fm theta, and the appearance time of Fm theta was enhanced by repetition. Type I of Spielberger's State-Trait Anxiety Inventory (STAI-I) demonstrated a higher state anxiety level of the subjects at the first trial. It may be concluded that the amount of Fm theta corresponds to the level in concentration of attention.
