Relationship between speed of information-processing and two major personality dimensions — Extraversion and neuroticism

Relationship Between the Big-Five Personality Dimensions and Speed of Information Processing Among Adolescents

“…A secondary cause of the obtained correlation is Eysenck's (1967) prediction of higher extraverts results in exterior conditions of heightened arousal, which are to a certain extent present in our research due to the competitive atmosphere of testing in groups and the optimal time of the day for the testing. These findings are consistent with the ones of Reeve et al (2006) and they slightly vary from the results provided by Sočan and Bucik (1998), which got correlations of the same sign, although somewhat higher. However, the findings are clearly different from the zero correlation in the research of Stough et al (1996), Luciano et al (2004) and Bates and Rock (2004), probably due to an essential difference of the SIP measures.…”

“…The highest relationship between SIP and Extraversion could stem from the nature of SIP tasks in this research which are motorically demanding. Sočan and Bucik (1998) report that Brebner's predictions say that extraverts tend to demonstrate fast and frequent motor reactions. Although motor mobility in this research is not specifically measured, it can be assumed this is the core of the Extraversion-SIP correlation.…”

“…5 A more probable limitation in reaching higher personality dimensions-Er-SIP correlations is the mentioned low variability of Er-SIP, which is the consequence of low error rates in the speed tests. However, Sočan and Bucik (1998) calculated the correlation between the error rate in a perceptual speed test with personality dimensions and obtained the correlation r=0.23, p<0.03 for one of the Extraversion subdimensions.…”

“…Sočan and Bucik (1998) studied the relationship between SIP, Extraversion and Neuroticism starting with Eysenck's arousal theory (Eysenck, 1967) and the Brebner-Cooper Extraversion model (Brebner, 1980). In addition to individual reaction times measures of SIP, Sočan and Bucik (1998) used three pencil and paper SIP tests and two different Extraversion and Neuroticism questionnaires.…”

In addition to individual reaction times measures of SIP, Sočan and Bucik (1998) used three pencil and paper SIP tests and two different Extraversion and Neuroticism questionnaires. The results showed: (1) a modest negative correlation between Extraversion and response time in most of SIP tests; (2) a modest positive correlation only between Neuroticism and decision time in the reaction time test, whereas the correlations between Neuroticism, movement time and all response times in pencil and paper SIP tests were zero; (3) curvilinear correlations between Extraversion scales and response times in SIP tests were not significantly higher than associated linear correlations; (4) only two curvilinear correlations between Neuroticism scales and response speed in SIP tests were significantly higher than associated linear correlations; (5) error rate in different SIP tests was not correlated significantly with any of the Neuroticism scales, and it was correlated significantly with only one Extraversion subscale (Sočan & Bucik, 1998).…”
