The Psychophysiology of Extraversion and Neuroticism

Electrodermal Response Lability-Stability: Individual Difference Correlates

“…This state of affairs continued to hold when several more studies were subsequently reviewed (O'Gorman, 1983). Both O'Gorman (1977) and Stelmack (1981) offered a variety of criticisms of those studies reporting null findings, most notably the use of low intensity stimuli in the assessment of specific lability. Nevertheless, the accumulated findings suggest a weak inverse relationship between EDR lability and extraversion.…”

Intelligence and Cognitive Control

“…Stelmack (1981), reviewing literature on N, indicated that the relation between neuroticism and psychophysiological responsiveness has not been reported with sufficient consistency to prove H. J. Eysenck's prediction on the biological determinants of N trait. However, postulated that neuroticism is related to individual differences in excitability and emotional responsiveness.…”

Regional patterns of cortical blood flow distinguish extraverts from introverts

“…Both studies of electrodermal orienting reactions and of conditioning tend to find the predicted differences between extraverts and introverts only under low to moderately arousing conditions (Levey & Martin, 1981;Stelmack, 1981). These findings have been linked to the main hypothesis by the added assumption that introverts are pushed beyond an optimum point by stressful conditions, resulting in decrements of performance and responsivity (Eysenck, 1967(Eysenck, , 1983.…”
