This study explores the relationship between lexical access and proficiency level in L2 speech production. Forty-one participants (intermediate and advanced learners of English as a foreign language) performed a lexical access task in L2 which yielded two measures: reaction time (RT) and naming accuracy (NA). The statistical analysis point to a facilitatory effect of semantic related word distractors on L2 picture-naming for the experimental and control conditions in both proficiency groups. In addition, only the mean difference in NA scores for the control and experimental conditions between proficiency groups reached statistical significance. That is, advanced learners overpassed the intermediate ones in number of words correctly named. Results also indicate a partial relationship between RT and NA scores. Findings are explained in light of research on L2 speech production, lexical access and working memory, taking into account the development of L2 proficiency and L2 lexical representations.
