Why else would so a number of of us automatically assume carrots are orange, grass is green and apples are red?
In two experiments by Holger Mitterer and Jan Peter de Ruiter from the Max Planck Institute for Psycholinguistics, perception of color and color constancy (the........Go to the Psychology news blog (Added on 7/22/2008 8:30:44 PM)
