Foreign language learning can improve response inhibition in individuals with lower baseline cognition: Results from a randomized controlled superiority trial

This study investigated the impact of foreign language learning on executive attention and cognitive functions in older adults (65–80 years old) through a randomized controlled trial. Participants took a 3-week intensive Spanish course. While overall cognitive improvements weren't significant, those with lower baseline cognitive performance showed gains in response inhibition, a key executive function. This suggests foreign language learning may especially benefit individuals more vulnerable to cognitive decline.

Older adults may consider learning a new language to engage their brain, particularly if they face early cognitive challenges. While benefits may vary, the activity promotes mental engagement and executive function improvements. As the research was limited in scale, further studies are necessary to confirm widespread effects.
