“…Research into differences between monolingual and bilingual performance and processing is not only relatively new, but has also produced conflicting findings, which fuels the existing social ambivalence relating to the acquisition of two languages in childhood. As a result, many parents and teachers worry that speaking a minority language at home or at school may hamper their children's achievement in the dominant language (see Gundarina & Simpson, 2021), despite a large body of more recent research that debunks this common belief (e.g., Papastefanou et al, 2019;Papastergiou & Sanoudaki, 2021).
