abstract：:As part of an investigation into real-world drawing, eye movements and eye-hand interactions have been recorded for twenty subjects of varying drawing experience drawing simple straight and curved lines and a square. Two modes of eye-hand behaviour were observed. In the first, named 'close pursuit', fixations closely ...

The congenital type, which is not accompanied by detectable brain damage or malformation, was recently found to be far more common than previously known. Therefore, one should expect that at least a few biographies or autobiograph...
