The relationship between RT and EEG activation, as defined by measurements of both amplitude and frequency (period) of waves from the dominant hemisphere, was investigated. A 250-c/sec. tone that was presented without a preparatory warning signal was the stimulus. Within-subject correlations from 99 Ss supported the hypothesis of an association between EEG activation and behavioral arousal. Frequency of the waves was a better predictor of RT than amplitude.
