“…However, some SLA researchers have argued that attention and subsequent learning may not necessarily involve conscious awareness (e.g., N. C. Ellis, 2005;Leung & Williams, 2012, 2014Tomlin & Villa, 1994;Truscott & Sharwood Smith, 2011;Truscott, 1998Truscott, , 2015. This view represents a stance within another current debate in SLA on whether L2 learning occurs implicitly (i.e., without awareness) or explicitly (with awareness), as upheld by other researchers (e.g., DeKeyser, 2003(e.g., DeKeyser, , 2007Leow & Cerezo, 2016;Robinson, 1995). These questions remain up for debate in SLA, and no definitive conclusions have been reached as to the scope, mechanisms, and measurement of implicit learning, especially considering methodological issues when tapping into implicit learning processes (see, e.g., DeKeyser, 2003;Leow, 2015;Rebuschat, 2013;Rebuschat & Williams, 2011).…”
