Neuroscientists have finally figured out why speaking a new language is so hard for adults
Spanish researchers used fMRIs to track neural activity as participants read, listened to, and spoke new languages over time. They found that as participants gained proficiency, their brains recruited from both hemispheres to read and comprehend; notably, their neural activity patterns for comprehension varied widely from person to person. But speech production remained firmly cornered in the left hemisphere, with minimal change.
Translation: It’s much easier to learn to read and understand than it is to speak fluently. This also suggests that speaking is hardwired to the left hemisphere, while comprehension is flexible, engaging more plasticity.
They also found that when first learning, the neural activity of native and new languages appear similar in the brain, but as students improve, the two languages’ neural activity becomes more distinct.
The take home message here: If speaking beautifully isn’t a priority, you’ll likely find more success learning to understand and read.
