“…Many studies on early FL learning conducted in European countries do not report any differences between minority language and majority language students in standardized comprehension or writing tests of the FL (e.g., Schoonen et al, 2003;Wilden & Porsch, 2016), and some studies even report significant disadvantages for minority language students as a group already at the primary school level (e.g., Elsner, 2007). However, when individual differences in cognitive skills and social background are controlled for, some selective advantages of minority language learners emerge (e.g., Hesse, Göbel, & Hartig, 2008;Maluch et al, 2015), yet multilingual boosts do not extend across all groups of learners (Göbel & Vieluf, 2017). In a recent study on German 9-10-year-old 3rd-and 4th-grade primary school minority and majority language students, Hopp, Vogelbacher et al (2019) reported that both cognitive and linguistic skills in the minority language contribute significantly to vocabulary and grammar skills in FL English.…”
