Abstract
Abstract Measures of amplitude of auditory Event-Related Potentials—in particular the P300 wave— were compared with measures of extraversion and introversion to determine whether there is a correlation between electroneurophysiological findings and psychological traits. Our results showed that the P300 wave—measured by electrodes placed at the Fz, Cz, and Pz sites—had greater amplitude in introverts. We found no significant differences between introverts and extraverts with respect to latency of the P300 wave.

The P300 (P3) event-related potential was obtained from 100 undergraduates with a 2-tone auditory discrimination task and replicated trial block procedure and was negatively correlated, most strongly at the Pz electrode site.

The multiplicity of components provides the field with more degrees of freedom in attempting to relate electrophysiological activity to behavior, and the likelihood increases that the field may be able to obtain ERP correlates of more of the dimensions involved in behavior.

The late positive component (P3) of the feedback evoked potential was investigated in two tasks: the detection of near-threshold auditory stimuli, and the estimation of 1 s time intervals and found that the feedback P3 component was highly dependent upon the probability of the Feedback, and relatively independent of its confirming or disconfirming meaning.

Event-related potentials were measured in normal young subjects during a memory-scanning paradigm modified from one proposed by Sternberg, and memory processes associated with the P3 complex in the 'odd-ball' task and the long-lasting positivity in the memory- Scanning task are discussed.

P3 amplitude was determined by principal components analysis and it was found to be significantly larger for the introverts than for the extraverts, interpreted as evidence that P3 amplitude is sensitive to individual differences in the allocation of attention.
