Competing in Visual “X” Games

Competing in Visual “X” Games

My colleague, Dr. Len Press says: "One of the reasons that visual difficulties are overlooked is the superficial or simplistic notion equating vision with activity in the occipital cortex at the rear of the brain.  Don’t get me wrong — I’m a big fan of V1 and all of the processing that goes on in the rest of the “Vs”.  But that’s only a small portion of what constitutes vision.  The sketch above is from a generally informative blog about Autism Spectrum Disorders that describes individuals with ASD as often having extreme visual strengths. Such extremist statements mask the extent of difficulties experienced by individuals with ASD.  One cannot dissociate the influence of executive control and other avenues of top-down knowledge on visual perception, one reason why the visual brain is so easily subjected to illusions....."
