Though we have long suspected that learning a foreign language can help to sharpen the mind, a new study has used EEG recordings to show just how much of an effect language learning has on our brains. The experiment showed that knowing more than one language helps to boost brain elasticity—a trait associated with the brain’s ability to change and improve over time. Results showed that the brain’s electrical activity in participants who already knew a foreign language was higher, and the more languages someone mastered, the faster the neuron network coding information about new words was formed.(more)
