“…In this article we will consider a number of types of memory, namely, phonological short‐term memory (PSTM), working memory capacity, declarative memory, and procedural memory. PSTM, the short‐term store for auditory information and articulatory rehearsal as measured by simple span tasks, has been implicated in vocabulary acquisition (Baddeley, Papagno, & Vallar, 1988; Gupta, 2003; Martin & Ellis, 2012; Papagno, Valentine, & Baddeley, 1991), and grammar abstraction (Ellis, 2012; Robinson, 1997; Speidel, 1993; Verhagen & Leseman, 2016). Working memory capacity, defined as the ability to not only hold but also simultaneously process items in short‐term memory and measured by complex span tasks, has been linked to the noticing of grammatical regularities in language and on‐line language processing (Coughlin & Tremblay, 2013; Mackey, Adams, Stafford, & Winke, 2010; Mackey, Philp, Egi, Fujii, & Tatsumi, 2002; Sagarra & Herschensohn, 2010).…”
