The effect of motor-response-deprivation on contingent negative variation (CNV). III: relation with Maudsley Personality Inventory (MPI).
The contingent negative variation (CNV) was correlated with Maudsley Personality Inventory (MPI) in 43 healthy adults as follows: (1) The conventional CNV with motor-response showed a negative correlation with the scores of extroversion in the MPI (E-scores). The recovery of the conventional CNV after verbal extinction showed both a negative correlation with the E-scores and a politive correlation with the scores of neuroticism (N-scores). (2) The motor-response-deprived CNV in the stimuli and nonresponse sessions (Sa and Na) showed no correlation with the MPI, because they fluctuated according to the subject's attentiveness. On the other hand, the CNV in the discrimination session (Da) with constant attentiveness to stimuli showed a positive correlation with the N-scores. (3) The response times in the control and response sessions showed a positive correlation with the N-scores in males and a negative correlation in females. The correlation with the E-scores was nearly opposite.
