Do anyone think why little kid paints trees blue or grass red?

Here we have a nice result about the query. A research made by a researcher from University of Wisconsin. It is because the kids can't connect together the colour and shape of an object. The reports say that the brain stores colour and shape in different groups of neurons, young children have not yet developed the ability to link the information stored in each.

To verify, the expert asked 28 four-year-olds and 28 five-year-olds to view images of up to three shapes on a computer screen for a squat time. After that children were shown a new image and asked whether it was the same as the previous.

They found that even though the 4 year kids could find out when a new colour had been introduced, they did not give the impression to notice if two of the shapes had just swapped their original colours. The 5 year kids had no such problem, signifying that the ability to merge the dissimilar types of visual information develops after the child's 5year, the study claimed.

The research will be presented at the annual meeting of the Cognitive Science Society in Amsterdam at the end of July.
