There has been an increased interest in L2 learners’ motivation and autonomy over the past several decades, and both variables are recognized as characteristics of successful language learners. The L2 motivational self system (L2MSS) is a recent approach to L2 motivation research that sheds light on many aspects of a language learners’ self. Additionally, autonomy is known to promote long-term foreign language learning success. Understanding these measures and what variables influence them can help educators determine how to best help their students achieve success in language learning. This study examines Taiwanese university students’ ideal L2 selves and autonomy as measured on questionnaires. This study seeks to examine whether any differences exist between Taiwanese students who attended normal, comprehensive, or vocational high school programs in Taiwan. The results show that while differences exist and several of the L2MSS and autonomy variables are strongly correlated, there are no significant differences between students in these three groups. The results suggest that there may be other variables not measured in this study which do have an impact on a learners’ L2MSS and/or autonomy.

This study explores the relationship between language competence and intercultural communicative competence (ICC) among English as a Foreign Language (EFL) learners through a mixed-methods approach. A sample of 196 Chinese EFL learners was divided into three proficiency groups (low, intermediate, and high), with data collected through Likert-scale questionnaires and semi-structured interviews involving 16 participants. Quantitative analysis revealed that higher language proficiency is linked to improved overall ICC scores and its specific dimensions. The Kruskal-Wallis H test confirmed significant differences in overall ICC, attitude, and skill across proficiency levels, with attitude showing the strongest effect. Spearman's correlation analysis demonstrated small but significant positive correlations between English proficiency and overall ICC, attitude, and skill. Qualitative findings further enriched the quantitative results, emphasizing the foundational and catalytic role of language competence in enhancing ICC and its dimensions. However, participants acknowledged that language competence alone is insufficient for fully successful intercultural interactions. This study expands Byram’s model by offering detailed insights into the intricate relationship between language competence and various ICC dimensions. The study recommends that to fully cultivate ICC, it is essential to integrate the development of language competence into instructional practices.
