“…In monolingual English-speaking children, it is noted that this shift generally occurs by about age 8 years (Nelson & Nelson, 1990). In bilingual children, this shift occurs earlier, at around age 6.5 years as evidenced in Spanish-English bilingual children (Peña, Bedore, & Zlatic-Giunta, 2002) and 6 years in Mandarin-English bilingual children (Sheng & Lam, 2015). In contrast to monolingual children, bilingual children add new words across both of their languages, and this increased number of words may drive them to adopt more efficient taxonomic-organization strategies at an early age.…”
