The benefits of speaking multiple languages can be seen in the brain, according to a South Korean study of young children.
Researchers in Hong Kong have found that all languages convey information at similar rates, regardless of whether they are spoken faster or slower.
Genetic and environmental factors have an equally strong influence on a pattern of brain activity associated with language ability.
No matter what language they speak, children learn words of quantity such as ‘all’, ‘some’ or ‘none’ in the same order.
Babies whose mothers speak a tonal language exhibit a more melodic crying pattern, according to a study.
