Abstract
The purpose of this study was to examine the relationship between Eysenck's personality dimensions and conditionability in verbal respondent conditioning. EPI was administered to 705 students, and 42 subjects with extreme scores and 13 with moderate scores were selected. They were assigned to four groups: 12 stable extraverts, 15 stable introverts, 15 neurotic introverts, and 13 ambiverts. Nonsense syllables as CS were paired with words with various affective tones. After a conditioning session using 15 CS-UCS pairs, all subjects were asked to recall the nonsense syllables, and estimate their affective tones. The number of syllables recalled and rated affective tones were used as indices of conditionability. The results showed that when negative words were used as UCS, introverts were more readily conditioned than extraverts. However, no significant relationship between neuroticism and conditionability was found.
