“…Cognate facilitation effects in children have been found both in vocabulary acquisition and in lexical processing. Most vocabulary acquisition studies have found cognate facilitation in the L2 (Bosma et al, 2019;Chen et al, 2012;Comesaña et al, 2012Comesaña et al, , 2019Hancin-Bhatt & Nagy, 1994;Kelley & Kohnert, 2012;Malabonga et al, 2008;Méndez Pérez et al, 2010;Proctor & Mo, 2009;Puimège & Peters, 2019;Robinson Anthony et al, 2020;Tonzar et al, 2009;Valente et al, 2018;Von Holzen et al, 2019) and this effect has been shown to be gradual: the more overlap between the L1 and the L2 word, the easier it is to acquire the new L2 word (Bosma et al, 2019;Valente et al, 2018;Von Holzen et al, 2019). A study with L1 English speakers in an L2 Spanish immersion program, however, showed that cognates can also enhance L1 vocabulary acquisition (Cunningham & Graham, 2000).…”
