The effects of mathematical, spatial and verbal task difficulty on EEG alpha amplitude and mean frequency asymmetry were investigated. Twenty right-handed subjects with no familial left-handedness (10 female, 10 male) were presented 3 levels of difficulty for each type of task. Difficulty was varied through increasing the rate of auditorily presented numerical stimuli. Also examined were EEG alpha correlates with measures of performance anxiety, subjective difficulty, loss of vigilance… CONTINUE READING
