Two of the “10 characteristics of CVI” are color and complexity. This means bright, highly-saturated hues that are solid colors (with little or no patterns) tend to be easier for someone with Cortical Visual Impairment to visually process.
Red is one of the first colors our brains learn to process as infants, so it’s no wonder Elmo is often a favorite of little ones with CVI! He is solid, bright red and easily identifiable with his simple eyes and big, orange nose.
Another CVI characteristic is novelty, which means a child with CVI will be drawn to the familiar since new people/places/things are much more challenging to visually process. Someone with CVI cannot simply “look” and learn what something new is; they must learn the distinct, salient features that categorize objects for what they are, which means new things require building a new framework of understanding in the brain…whereas familiar objects are ones the brain has already learned to “see” (process).
