The Ser radio has echoed an investigation conducted by Dr Cristian Farias, PhD student in our research group. In this research, to determine this influence, the researcher compared monolingual older people with bilingual ones. Half of the bilinguals were from a very young age (before the age of four) and the rest, from a more mature age (after eighteen). The study involved 90 people, 60 of whom were bilingual with residence in Mallorca and 30 monolinguals and residents of Punta Arenas, Chile.
