Delving into L2 Learners’ Perspective: Exploring the Role of Individual Differences in Self-Evaluation of L2 Speech Learning

Misalignment between second language (L2) self-perception and actual ability is often observed among L2 learners. In order to further understand this phenomenon, the current study investigated how the roles of individual differences (IDs; especially experiential and cognitive IDs) influence the learners’ self-assessment accuracy. To this end, L2 speech samples elicited from 97 Japanese learners of English were analyzed via self-evaluation and expert evaluations. Subsequently, learners’ IDs profiles, including working memory, phonological memory, implicit learning and auditory processing, were linked to (a) the gap between self- and expert evaluation scores and (b) the type of inaccurate self-evaluation (i.e., overconfident vs. underconfident evaluations). The study illustrates the complex relationships between L2 learners’ linguistic knowledge, cognitive abilities, experiential profiles and self-perception.
