“….the human visual system is capable of simultaneously processing several traits of a single object.”


“Our eyes are drawn to several dimensions of an object—such as color, texture, and luminance—even when we need to focus on only one of them…points to the ability of our visual system to integrate multiple components of an item while underscoring the difficulty we have in focusing on a particular aspect of it.

“Even when we want and need to focus on one dimension of things we come across every day, such as the texture of your cat’s fur rather than its lightness, we have difficulty doing so because our eyes want to survey several features at once…when a visual task becomes difficult, we find that humans cannot ignore a visual dimension even if it harms their performance.”
