This study investigates whether working memory capacity (WMC) varies across languages and in the course of L2 speech proficiency levels. Following suggestions in Finardi and Weissheimer (2009) and Prebianca (2010), who found that WMC varied as a function of L2 speech proficiency, the present study assessed three proficiency levels (elementary, intermediate and advanced) and two languages (L1-Portuguese and L2-English). Two WM tests were used, one in the L1 and another in the L2, both in the speaking mode. Sixty adult learners of English as a foreign language participated in the study: 19 elementary, 19 intermediate and 22 advanced learners. Results of Kruskal-Wallis and Mann-Whitney tests corroborate Finardi and Weissheimer (2009) and Prebianca (2010) suggesting that WMC measured with a speaking span test in L2 seems to conflate the relationship between speech proficiency levels and WMC.
