摘要：Scientific views on reading have remained controversial even after a considerable amount of
research in several disciplines. Psychological research on word recognition considers this a
process of grapheme to phoneme conversion and most theories assume that reading depends
heavily on metalinguistic knowledge and therefore is a language based phenomena. This view
gives less importance to visual theories of reading. However recent work in the neuroscience
and psychophysics of visual processing suggests that many important aspects of visual word
recognition are based on visual processing and that seemingly low level factors exert
considerable influence on reading speed and accuracy. This view has serious implications for
understanding psychological mechanisms of reading as well as processing limitations,
stemming from brain abnormalities, found in visual word recognition in dyslexics.
