“…Methodological syntheses in L2 research have been both broad and narrow in focus, with some attending to individual substantive domains (e.g., interaction in Plonsky & Gass, 2011; L2 writing in Liu & Brown, 2015) and others concerned with different aspects of research design, analyses, and reporting practices, such as instrument development (Derrick, 2016), factor analysis (Plonsky & Gonulal, 2015), multiple regression (Plonsky & Ghanbar, 2018), use of effect sizes (Norouzian & Plonsky, 2018; Plonsky & Oswald, 2014), reliability coefficients (Plonsky & Derrick, 2016), statistical assumptions (Hu & Plonsky, 2019), and others (e.g., Al-Hoorie & Vitta, 2019; Plonsky, 2013). Furthermore, methodological syntheses have also focused on individual research tools, such as grammaticality judgment tasks (Plonsky, Marsden, Crowther, Gass, & Spinner, 2019) and eye-tracking (Godfroid, 2020), as well as instructed second language development (Sok, Kang, & Han, 2019). Most pertinent to the present study is Marsden et al's (2018) review of SPR tasks, which demonstrated a number of inconsistencies in how SPR data are cleaned and handled.…”
