"The traditional view of the brain's visual system suggested that when you see an object, your brain breaks it down into basic features—such as color, shape, and texture—and then reassembles these features to help you recognize and categorize it.
According to this view, the ultimate aim is to assign an object to aspecific category, like recognizing that a dog is an animal. However, Martin Hebart, a group leader at the Max Planck Institute states, "Our results have shown that recognition and categorization are important goals of our vision, but by no means the only ones." Hebart adds that behaviorally relevant signals are found at all stages of visual processing, and these signals extend beyond mere recognition.
They identified 66 different dimensions based on behavioral data gathered from more than 12,000 participants.
These dimensions do more than just help categorize an object as, for example, a dog or an animal. They also explain various attributes like color, shape, and the typicality of an object—such as how typical a dog is as a representative of the animal category.
This broader set of dimensions allows a deeper understanding of how the brain perceives and makes sense of the environment....... the brain does not only recognize and categorize objects; instead, it processes a wide array of characteristics, engaging all perceptual processing stages."
