Extraversion‐introversion, Neuroticism and the Eeg

Occipital EEG was monitored during habituation trials to a regularly presented auditory stimulus. The subjects were selected in accordance with a factorial design which varied extraversion–introversion and neuroticism independently. A double‐blind procedure was adopted for recording, scoring and statistical analysis. The EEG of extraverts and introverts was not differentiable; however, high neurotic groups were shown to have significantly greater EEG abundance than low neurotic groups across several frequency bands. There were no readily explicable interactions between the personality variables. For all subjects, two distinct response patterns appeared: (i) EEG attenuation (trials 1–3) and (ii) EEG augmentation (trials 4–20). Recovery time from stimulation may be longer than 10 sec. Both attenuation and augmenting responses are subject to the law of initial values. There were no differences in response amplitude or in speed of habituation for the personality groups
