New research found out that babies exposed to multiple languages have better music sensitivity in the first year of infancy. Compared to infants growing up and learning only one language, individuals who grow up listening and learning more than one language are more sensitive to the subtle pitch variations in language. Using music pitch, both babies were set to test for sensitivity. Results showed that bilingual babies can distinguish between to violin notes better than their monolingual counterparts.
Learning two different languages at the same time makes a child form a more detailed and complex system. With overlapping sounds, better acoustic comprehension is achieved. The experience of distinguishing differences between two languages is not confined in learning language alone but extends to non-speech perception such as music. They also pay attention to input acoustic details which becomes an exercise to the brain and the ears.
As bilinguals, the effect of its benefits is not restricted to the language domain. In fact, when they talk, all the language they know are activated by the brain. Scholars stated that babies growing up learning two languages have better cognitive abilities such as executive control. The practice from an early age has life-long benefits and makes them more adaptive, abstract and creative when they grow into adult. Positive results are manifested early in the infancy period.
Aside from keen sensitivity to language and music, they are also able to perform better at identifying and detecting new information, switching to new rules and response targets while suppressing the old learned rules, better degree of brain plasticity, recognition between languages, learning two speech structures simultaneously, interpretation of speech, sensitivity of visual cues, social communication skills and bigger working memory.
Though there are old claims quoting that children growing up as bilingual have slower cognitive growth and mental trajectory, modern research showed just as the contrast. Bilingual children can separate the two languages early on and that their language development is not different from that of a monolingual; in fact, they develop better. Raising your child knowing and learning two different languages may change your perception, cognition and even brain structures.
