Abstract

This experiment used a circle tracing paradigm to extend our recent theoretical development concerning the contributions of extraversion and neuroticism to impulsive performance on continuous motor tasks. Subjects (N = 137) completed the Eysenck Personality Questionnaire and were randomly assigned to 1 of 2 circle conditions: The goal condition provided subjects with a salient behavioral end point for their tracings, whereas the no-goal condition promoted behavioral uncertainty. In both conditions, Ss were asked to trace the circle under neutral and inhibition instructions. Using Gray's impulsivity and anxiety dimensions to group subjects, impulsive subjects under inhibition instructions displayed significantly faster tracing speed than nonimpulsive subjects in the presence of a salient goal, whereas anxious subjects appeared behaviorally impulsive in a situation promoting uncertainty and response conflict. Conceptualizing impulsivity and anxiety in terms of extraversion and neuroticism, with impulsive Ss as neurotic extraverts and anxious Ss as neurotic-introverts, it is proposed that Ss' level of extraversion determines the type of stimuli to which they are responsive, and that level of neuroticism influences the magnitude of this reaction.
