    Abstract:
    Clicks were delivered in trains of 2,5 s duration at click repetition rates of 5 or 8/s to provoke rhythmical activity in the vertex-EEG ('driving response') and to condition the driving response to neutral stimuli in a discrimination paradigm. The Eysenck Personality Inventory was administered to define an independent personality variable, i.e. extraversion-introversion; the interaction of background activity, driving and conditioned driving response with the personality dimension was analyzed. In the background EEG there was a significant difference in the absolute power of the fast alpha-band between introverts and extraverts. Driving was only observed in the fundamental frequency of acoustic stimulation, not in the first harmonic. There was no interaction between driving response and extraversion-introversion or resting EEG activity. Classical conditioning of the driving response was successful with introverts only. Results were interpreted within the framework of Eysenck's personality theory. The possibility to study neurophysiological correlates of memory processes in humans by means of conditioned driving responses is discussed.
