Personality and Second Language Learning: Trends and Insights from a Bibliometric Perspective

This study investigates the relationship between personality types among second language (L2) learners through a bibliometric analysis. Personality traits, particularly the Big Five, are recognized as key predictors of L2 success. However, despite numerous empirical findings, the strength and nature of these correlations often show significant inconsistencies. Utilizing CitNetExplorer and VOSviewer, this study analyzes 161 research articles sourced from the Web of Science database. The analysis highlights major contributors, organizations, and countries in this field, emphasizing the impactful work of highly cited scholars, as well as leading research regions. The findings indicate that Openness, Conscientiousness, and possibly Agreeableness are significantly correlated with L2 achievement, while Neuroticism tends to show marginal or no correlation. These general trends are complicated by methodological inconsistencies in measures of L2 achievement and personality assessment tools. This study advocates standardized protocols for cross-cultural research and suggests further exploration using alternative personality measures. Additionally, personalizing teaching strategies based on learners’ personality types may enhance L2 outcomes.
