ABSTRACT
Purpose We report a preliminary study that prospectively tests the potential cognitive enhancing effect of foreign language (FL) learning in older adults with no clear signs of cognitive decline beyond what is age typical. Because language learning engages a large brain network that overlaps with the network of cognitive aging, we hypothesized that learning a new language later in life would be beneficial. Method Older adults were randomly assigned to 3 training groups: FL, games, and music appreciation. All were trained predominately by a computer-based program for 6 months, and their cognitive abilities were tested before, immediately after, and 3 months after training. Results FL and games, but not music appreciation, improved overall cognitive abilities that were maintained at 3 months after training. Conclusion This is the 1st randomized control study providing preliminary support for the cognitive benefits of FL learning.
