RELATIONSHIP BETWEEN THE BIG-FIVE PERSONALITY DIMENSIONS AND SPEED OF INFORMATION PROCESSING AMONG ADOLESCENTS

Abstract

A developmental research of the relationship between the Big-Five and speed of information processing (SIP) was conducted with the aim of considering the personality-intelligence relationship. Personality dimensions were assessed by International Personality Item Pool (IPIP) questionnaire, while SIP and related test errors (Er-SIP) were assessed by Cognitive Abilities (KS2-2) pencil and paper perceptual speed test. The sample consisted of 1063 adolescents (378 males) at the age range from 14 to 18. The preliminary analyses showed that: (1) age related changes of SIP were weak and those of personality dimensions barely existed, (2)modest gender differences are found for all personalitydimensions except for Intellect, and they are not found for SIP and Er-SIP, (3) reduced variability and significant distribution skewness systematically appeared only at Er-SIP, and (4) personality dimensions-SIP relationship was not curvilinear. The main analyses showed that: (1) SIP had low positive correlations only with Extraversion and Agreeableness, (2) Er-SIP didn't correlate with personality dimensions at all and (3) personality dimensions-SIP relationship mostly insignificantly depends on age and gender.
