Infants can sense colours even before they can speak
Infants aged between five and seven months are able to categorise colours in their brain, even before the acquisition of language, according to Japanese researchers. A long-held theory called Sapir-Wharf hypothesis claims that languages define our perceptions.
Tokyo: Infants aged between five and seven months are able to categorise colours in their brain, even before the acquisition of language, according to Japanese researchers. A long-held theory called Sapir-Wharf hypothesis claims that languages define our perceptions.
Colour perception is also considered to be subject to this theory since colours are called by their names in daily communications. However, according to the new study, the category of colours can be independent of language, at least in the early stage of development in an infant's visual system.
The researchers from Chuo University, Japan Women's University and Tohoku University tested 5-7 months old infants to see if brain activity is different for colours in different categories. The brain activity was measured by a near infrared specrtoscopy technique which realises comfortable measurement of brain activity in infants.
