More parents in Indonesia are introducing foreign languages to their children at an early age, reflecting growing interest in the potential cognitive benefits of multilingual learning beyond communication skills.

Research cited by language-learning platform Duolingo suggests that learning a new language regularly engages memory, attention, problem-solving and cognitive flexibility. A study by Baycrest and York University found that adults who used Duolingo for about 30 minutes daily over four months showed measurable improvements in executive function, including working memory, focus and adaptability.

“Learning a new language does more than expand a child’s vocabulary — it also helps train how they recognize patterns, connect information, and adapt to different contexts. Across various studies, these abilities have been linked to the development of cognitive flexibility, which serves as an important foundation for learning and problem-solving in everyday life,” said child, adolescent and family psychologist Ayoe Sutomo. She added that consistency, enjoyable learning experiences and parental supervision remain key factors in helping children succeed in language acquisition.
