Personality of the learner is another controversial matter being considered a factor influencing foreign language acquisition. A widely-held belief claims that extroverted learners learn more rapidly and are more successful than introverted learners. Krashen (1981, according to Ellis, 1985:120) argues that “an outgoing personality may contribute to acquisition.” Likewise Rossier (1976, as quoted in the same source) found out that his subjects’ oral fluency correlated significantly with extroversion/introversion. However, there are some research results that contradict the above findings. Naiman et al. (1978, quoted in Ellis, 1985) found no significant relationship between extroversion/introversion and proficiency. Similarly, Swain and Burnaby (1976, according to the same source) did not find the expected relationship between the measures of sociability and talkativeness on the one hand and proficiency on the other in the early stages of acquisition of French as a L2. Similarly, social skills and inhibition are considered segments of one’s personality possibly influencing foreign language acquisition; however, research findings about their actual effect are rather controversial.
