The relationship between second language acquisition and nonverbal cognitive abilities.

This research investigated the relationship between acquiring a second language (L2) through immersion and non-verbal cognitive abilities in children. Using a longitudinal design, the study assessed children's executive functions (like inhibitory control, attentional shifting, and working memory) before and after one year of immersion. Findings showed that better executive function skills predicted more success in L2 acquisition and improved native language skills (L1). The study highlights that L2 immersion may enhance cognitive functions, suggesting a reciprocal relationship between bilingualism and cognitive development.

Engaging in immersive language learning could benefit brain health by enhancing executive functions like memory, attention, and cognitive flexibility. While this study was specific to children, adults might also gain similar cognitive advantages. However, benefits could vary, as this was an observational study with no control group.
