The relationship between oral character traits and extraversion/neuroticism

The present study was a factor-analytic study attempting to uncover the relationship between the psychoanalytic concept of oral traits and the personality dimensions of E and N. Two hundred and fifty-four Ss completed the Eysenck Personality Inventory (EPI) and thewritten form of the 19 oral scales designed by Goldman-Eisler. The data was subjected to factor analysis. It was found that five factors were necessary to account for the majority of the observed common variance. The extraction of five factors was contrary to the extraction of two factors in the Goldman-Eisler study. Path analysis, using multiple regression, was performed to find to what extent E and N influenced the 19 oral scales. It was found that 15 of the 19 scales were significantly causally influenced by E and N. Because there were discrepancies between the correlations in the present study and those reported by Goldman-Eisler, and discrepancies in the number of factors to emerge were found, it was decided to subject the original correlation matrix of the Goldman-Eisler study to re-analysis. The results of this re-analysis demonstrated serious mathematical flaws in Goldman-Eisler's results.     

The relationship between extraversion and verbal-imagery learning style in twelve-year-old children

The extraversion score of 12-yr-old children was compared with a measure of their verbal-imagery learning style and their immediate recall performance on concrete and abstract prose passages. Learning style was assessed by the verbal-imagery code test which attempts to monitor the presence of verbal associations and images during information processing. The test gives a ration which when high indicates high imaginal and low verbal performance, and when low the reverse. Extraversion was found to be significantly negatively correlated with the verbal- imagery code ratio. Further, a significant interaction between extraversion and passage type in their effect on recall was observed. Extraverts were superior on the abstract passage, while introverts did best on the concrete material. The findings were consistent with the interpretation that extraverts are verbalisers and introverts are imagers.     

The relationship between the EPI extraversion score and impulsiveness on a perceptual-motor task

This paper describes an investigation of the relationship between extraversion and impulsiveness. These two traits were measured respectively by the Eysenck Personality Inventory (EPI) and the IES Arrow-Dot test. The subjects were 50 males and 50 females matched for age. Arrow-Dot impulsiveness was found to correlate significantly with extraversion in both samples. In the female sample Arrow-Dot impulsiveness correlated only significantly with the ‘impulsiveness’ component of extraversion. In the male sample both the ‘impulsiveness’ and ‘sociability’ components of the extraversion factor contributed about equally to its variance.     

On the relationship between explicit and implicit self-concept of extraversion and neuroticism

Indirect methods such as the implicit association test (IAT) could complement traditional self-report questionnaires of personality traits. However, it is unclear whether IAT scores and self-report scores of nominally the same personality trait measure the same construct or overlapping but distinct constructs. To investigate how IAT and self-report personality scores relate to each other, we conducted a web-based data collection where participants completed self-report personality questionnaires (n = 432) and IATs for extraversion (n = 393) and neuroticism (n = 385). We found that extraversion self-report and IAT scores were more strongly correlated with each other than corresponding neuroticism scores. Overall, our findings suggest that although extraversion and neuroticism self-report and implicit measures are related, they do measure distinct constructs.     

The dynamic role of personality States in mediating the relationship between extraversion and positive affect

One of the most noteworthy and robust findings in personality psychology is the relationship between extraversion and positive affect. Existing theories have debated the origins and nature of this relationship, offering both structural/fixed and environmental/dynamic explanations. We tested the novel and straightforward dynamic hypothesis that part of the reason trait extraversion predicts trait positive affect is through an increased propensity to enact extraverted states, which in turn leads to experiencing more positive affect states. We report 5 experience sampling studies (and a meta‐analysis of primary studies) conducted in natural environments and laboratory settings in which undergraduate participants (N = 241) provided ratings of trait extraversion, trait positive affect, extraversion states, and positive affect states. Results of primary studies and the meta‐analysis showed that relationships between trait extraversion and trait positive affect were partially mediated by aggregated extraversion states and aggregated positive affect states. The results supported our dynamic hypothesis and suggested that dynamic explanations of the relationship between trait extraversion and trait positive affect are compatible with structural explanations. An important implication of these findings is that individuals might be able to increase their happiness by self‐regulating their extraverted states.     

The hardy personality and its relationship to extraversion and neuroticism

Hardiness is conceptualised as a personality characteristic which encompasses three component traits (commitment, challenge and control), and acts as a resistance resource mitigating the adverse effects of stressful life events (Kobasa, 1979). A number of empirical studies in the U.S. have demonstrated its role in moderating stress-illness relationships, but hardiness has not received much attention in the U.K. In the present article, data from a U.K. sample (N = 87) are used to examine (i) the psychometric characteristics of the current version of Kobasa's hardiness measure, and (ii) the relationships of hardiness, and its component scales, to the Eysenck dimensions of extraversion, neuroticism and the lie scale.Hardiness scores were found to be negatively related to age, but did not differ significantly between males and females, and were not influenced by social desirability biases. The alpha value for the reliability of the overall scale was 0.89. Scores on the components of commitment, challenge and control were strongly related to extraversion (positively) and to neuroticism (negatively), the canonical correlation being 0.60. Multiple regression analysis showed that age, gender and the Eysenck dimensions jointly accounted for 37% of the variance in hardiness scores. These results are discussed in relation to psychometric issues and relevant literature findings.     

The relationship between psychometric intelligence and inspection time

The relationship between psychometric intelligence and inspection time (IT) is reviewed. Results are contradictory, which makes questionable the reliability of this relation. Moreover, the hope that IT constitutes a measure of ‘culture fair’ intelligence has not been confirmed and its correlation with tests considered to be culture fair and tests supposedly influenced by culture are not very different. The results do not allow us to establish a greater correlation between IT and specific factors of intelligence like verbal, spatial or numerical ability. Procedural problems apparent in measuting IT could explain, in part, the variability in results.     

The relationship of Laing's concept of ontological insecurity to extraversion and neuroticism

Four components were extracted from Laing's concept of ontological insecurity and operationally measured. The desire to be noticed was found to be correlated with extraversion while doubts in one's existence was related to neuroticism. The desire to be remembered after death and the rootedness of the mind in the body were not related to extraversion or neuroticism scores.     

The relationship between estimates of foreperiod duration and simple time reaction

The relationship between estimates of foreperiod length and simple reaction time (RT) was examined using constant foreperiods. It was learned that neither the average accuracy nor the variability of the foreperiod estimates necessarily manifested themselves in appropriate simple RT change. Of secondary interest was the discovery that the average accuracy of foreperiod duration estimations differed greatly from that obtained for similar time lengths in a time-estimation task. Finally, an attempt was made to determine whether subjects actually utilized the directional knowledge of results inherent in the imperative stimulus to influence their foreperiod duration judgments. Unfortunately, the evidence obtained did not permit a definite answer regarding this possibility.     

Cosmetic surgery and the relationship between appearance satisfaction and extraversion: Testing a transactional model of personality

Few studies have tested potential explanatory mechanisms for the high stability of extraversion. In this study, the relationship between extraversion, appearance evaluation, and cosmetic surgery was investigated to examine such mechanisms. The “Big Five” personality traits were assessed in 155 female cosmetic surgery patients prior to and 6 months after surgery, as well as from a representative sample of 907 women. Patients showed higher extraversion scores prior to surgery than were found in the representative sample; further, extraversion scores increased after surgery, while the increase diminished when controlled for appearance evaluation. The results are in accordance with a transactional model, whereby extraverts engage in actions that reinforce extravert tendencies, which may account for the high stability of extraversion.     

The relationship between three auditory inspection time tasks and general intelligence

Three inspection-time tasks measuring the amount of time required to discriminate differences in pitch, loudness and phase were administered alongside the Multidimensional Ability Battery and Raven’s Advanced Progressive Matrices to 75 undergraduate students. The auditory tasks were administered adaptively, and thresholds were estimated by fitting a logistic function to each set of data. After correcting for restriction of range the three thresholds intercorrelated significantly, and correlated between −0.33 and −0.68 with scores on the ability tests. A composite auditory inspection time score correlated between −0.35 and −0.42 with the ability measures (−0.50 to −0.54 after correction). Although strategy-use enhanced performance on the pitch inspection-time task, strategy use was unrelated to intelligence and did not mediate the correlation between inspection time and intelligence.     

The relationship between reaction time and intensity in discrete auditory tasks

The effect of signal intensity upon reaction time (RT) was studied in three auditory RT tasks in which the signal was a tone of high or low frequency. Experiment I showed the well-known negative gradient with intensity of simple RT when the subject was instructed to ignore the frequency and give the same response to both tones. But when the subject had to discriminate the frequency in a choice RT task, the RT/intensity relationship appeared to be U-shaped. Experiment II showed that when the subject was required to make a response to one signal but withhold it for the other, a task which requires discrimination of the frequency of the tone but removes the necessity to choose between overt responses, no increase in RT at high intensities was obtained. The results indicate that it is the response choice stage rather than the stimulus encoding stage which is retarded at higher energy levels. Experiment I also demonstrated that visual and auditory leading signals have similar facilitating effects without affecting the RT/intensity relationships.     

Beneath the Surface: Uncovering the relationship between extraversion and organizational citizenship behavior through a facet approach

To date, an empirical link between the broad factor extraversion and organizational citizenship behavior (OCB) has not been found. We propose that a facet conceptualization of extraversion including surgency, sociability and positive emotions predict an individual's level of citizenship behaviors in opposing ways, thus masking the predictive ability of a broad factor of extraversion. In study one, we establish the foundation for predictive differences by documenting differential relationships between the facets of extraversion and the type of organizational cultures potential job applicants are attracted to. In study two, analysis of peer rated OCB from 117 individuals working in various organizations supports the superior predictive ability of the facets over that of the broad factor.
