“…Nevertheless, the claim that immersion learners typically have strong L2 comprehension is well supported as they reliably demonstrate L2 skills sufficient for completing appropriate grade-level content (Alanís, 2000;Cazabon, Nicoladis, & Lambert, 1998;Cheng, Li, Kirby, Qiang, & Wade-Woolley, 2010;Genesee, 1987;Harley, Hart, & Lapkin, 1986;Knell et al, 2007;Lindholm-Leary, 2011;Swain & Lapkin, 1982;Turnbull et al, 2001). Assessments that measure L2 proficiency by tracking immersion learners' holistic listening and reading comprehension (e.g., Genesee, 1981;Harley & Hart, 1997;Siegel et al, 2010;Swain & Lapkin, 1982;Turnbull et al, 1998) are certain to have more validity in predicting academic success than a psycholinguistic experiment, yet such assessments offer little evidence about the precise nature of immersion learners' comprehension of particular linguistic features. As a result, how these populations interpret specific components of L2 morphosyntactic structures is a relatively unresearched topic.…”
