Infants can sense and respond to colours even before they learn to communicate. Sapir-Wharf hypothesis claim that it is language that defines our sensitivity. Japanese researchers have proved that infants between five and seven months are able to distinguish between colours. Their brains are more responsive to colours as a stepping step to sense.
The advanced version of the same theory says that the language can be independent of the names of the colours in the growth of infants in relation to the visual sensory of infants.
The researchers at Chuo University, Japan Women’s University and Tohoku University had their research done on 5-7 months old infants to understand the reception of the brain to different colours belonging to different divisions of the visual light.
An infrared spectroscopy technique was used to measure the activity of the brain in infants.
The Journal of Proceedings of the National Academy of Sciences published a research work which found that the brain showed significant responses when colours of green and blue were altered whereas the brain did not respond to the single shades of green. The study was done separately for the left and right hemispheres of the brain.
Brain activity that causes difference in colour was not to be found in the occipital region
which actually plays a major role in the visual processing.
