“…This perspective, broadly referred to as a social-ecological or systems framework, has been widely explored in the context of human development (e.g., Bronfenbrenner, 1977 ). Inspired by this and other related approaches within the language sciences ( de Bot, 2008 ; de Bot et al, 2007 ; Douglas Fir Group, 2016 ; Haugen, 1972 ; Sachdev & Bourhis, 2001 ; Steffensen & Fill, 2014 ; Yim et al, 2019 ), we developed a Systems Framework of Bilingualism ( Titone & Tiv, 2023a ; 2023b ; Tiv, Kutlu, Gullifer, et al, 2022 ) to operationalize the many layers of socio-ecological contextual information, including interpersonal and ecological language dynamics , using cross-disciplinary quantitative tools such as social network analysis and geospatial demographic analysis. Although these approaches have been discussed in the context of language acquisition (e.g., de Bot, 2008 ; de Bot et al, 2007 ), writing development (e.g., Baba & Nitta, 2014 ), foreign language anxiety (e.g., Mahmoodzadeh & Gkonou, 2015 ), irony comprehension ( Tiv et al, 2023 ), and speech perception ( Kutlu, 2020 ; Kutlu et al, 2022a , 2022b ), other facets of the bilingual experience have not yet been considered.…”
