ABSTRACT
It has been proposed that magnocellular deficits cause the reading problems in dyslexia. However, how magnocellular deficiencies are supposed to cause these problems is unclear. Recently it has been proposed that reading performance is limited by the L-/M-cone inputs to the magnocellular system. However, as explained in this review, this is problematic for a number of reasons. Particularly difficult is the linking of L- and M-cone sensitivity specifically to the magnocellular system.
Notes
Chase et al. (Citation2007, p. 229) wrote, “These MC pathway abnormalities may affect motion perception in dyslexics.” In this connection, they cite seven papers out which four deal with coherent motion.
