Anxiety and depressive disorders and the five-factor model of personality: a higher- and lower-order personality trait investigation in a community sample.

We describe in detail normal personality traits in persons with psychiatrist-ascertained anxiety and depressive disorders in a general population sample. We investigated Revised NEO Personality Inventory traits in 731 community subjects examined by psychiatrists with the Schedules for Clinical Assessment in Neuropsychiatry. All of the lifetime disorders of interest (simple phobia, social phobia, agoraphobia, panic disorder, obsessive-compulsive disorder (OCD), generalized anxiety disorder, major depressive disorder (MDD), and dysthymia) were associated with high neuroticism. Social phobia, agoraphobia, and dysthymia were associated with low extraversion, and OCD was associated with high openness to experience. In addition, lower-order facets of extraversion (E), openness (O), agreeableness (A), and conscientiousness (C) were associated with certain disorders (specifically, low assertiveness (E) and high openness to feelings (O) with MDD, low trust (A) with social phobia and agoraphobia, low self-discipline (C) with several of the disorders, and low competence and achievement striving (C) with social phobia). Neuroticism in particular was related to acuity of disorder. Longitudinal study is necessary to differentiate state versus pathoplastic effects.

Trends in the psychophysiology of individual differences.

Pavlov's typology of higher nervous activity was the first systematic approach to the psychophysiology of individual differences. Pavlov's theory has been further developed by Teplov, Nebylitsyn and their pupils in the Institute of Psychology in Moscow. In particular, Nebylitsyn has delineated a new property of the nervous system and has shown that it is different from strength of nervous system. In the Western research context we can compare the relationship between these two parameters to that between arousal and conditioning level. Eysenck's theory of the physiological bases of extraversion/introversion is discussed in relation to Nebylitsyn's theses and Gray's conception of arousability. Finally, it is suggested that future work in the psychophysiology of individual differences should stress the study of the ontogenetic development of the physiological variables.

The absent mind: further investigations of sustained attention to response.

We have previously demonstrated that performance on a brief and conceptually simple laboratory task (the Sustained Attention to Response Test: SART) was predictive of everyday attentional failures and action slips in brain injured patients and normal control participants. The SART is a go-no-go paradigm in which the no-go target appears rarely and unpredictably. Performance on this measure was previously interpreted as requiring sustained attention to response rather than a putative 'response inhibition' capacity. Three further studies are presented which support this claim. They demonstrate that performance is crucially determined by the duration of time over which attention must be maintained on one's own actions that this demand underpins the task's relationship to everyday attentional lapses. In keeping with a number of recent studies it suggests that inefficiencies in the maintenance of attentional control may be apparent over much briefer periods than is traditionally considered using vigilance measures and analysis.

Reaction to punishment, reflectivity, and passive avoidance learning in extraverts.

Passive avoidance learning occupies a central role in accounts of disinhibited behavior, ranging from psychopaths' persistent criminality (Hare 1970) to extraverts' gregariousness (Gray, 1972). To explore the mechanism underlying passive avoidance deficits, we assessed the relation of extraversion, neuroticism, and response latency after punishment to passive avoidance learning by using two successive go/no go discrimination tasks. The tasks were designed to examine two aspects of subjects' reactions to punishment: response speed on trials immediately following punishment (Experiment 1) and time to terminate punishment feedback between successive trials (i.e., reflectivity; Experiment 2). Consistent with previous findings, the results of Experiment 1 showed that extraverts commit more passive avoidance errors than introverts do (Newman, Widom, & Nathan, 1985) and fail to pause following punished errors (Nichols & Newman, 1986). In Experiment 2, only neurotic extraverts displayed this pattern of performance differences. In both experiments, longer pausing following punishment predicted better learning from punishment for both introverts and extraverts. These results suggest that, in the presence of salient cues for reward, extraverts' characteristic reaction to punishment interferes with processing punished errors and may contribute to their more general propensity for impulsive, nonreflective action.

Extroversion and reminiscence following a frustrating paired-associate task.

Two experiments were reported relating extroversion to reminiscence following a frustrating paired-associate (PA) task. In the first experiment a group of 30 male and female college students was randomly assigned to one of two tasks in which they learned a PA list of high or low stimulus similarity. All PA lists were mixed lists composed of half solvable and half unsolvable (randomized) stimulus-response items. Recall for solvable items was tested immediately, 15 min, and 30 min after criterion was reached. Results indicated a significant difference between high and low stimulus similarity with superior recall for low similarity. The predicted reminiscence effect for high stimulus similarity recall was present but not significant. Comparison of recall scores for extroverts and introverts indicated a significant difference in recall favoring the introverts. The second experiment made a similar test of recall for two groups of S s that had been established as extreme extroverts or introverts (N = 8 in each group). The superiority of recall for introverts was replicated, and a reminiscence effect was found for the extroverts. Results were discussed in relation to Eysenck's formulation and previous conflicting results.
