The importance of additional language learning (ALL) is on the rise, but we do not yet have a full understanding of how learners with different characteristics approach this task. Here, we discuss the potential impact of attention-deficit/hyperactivity disorder (ADHD), a prevalent learning disability, on classroom ALL. Learners with ADHD show difficulties in the attention networks of sustained attention and executive control. It is critical, therefore, to ask how these difficulties of learners with ADHD might manifest in the demanding task of ALL, but to date there is very limited research examining this issue. The current paper sets out a theoretical framework for examining ALL in learners with ADHD, reviews the extant literature, and most importantly calls for future research to examine the way in which learners with ADHD manage the process of ALL, in an effort to highlight the involvement of sustained attention and executive control in ALL more generally.
