A parallel distributed processing model of visual word recognition and pronunciation is described. A key feature is the assumption that there is a simple, uniform procedure for computing a phonological representation from an orthographic representation for irregular words as well as regular words. (SLD)

A study assessed the role of orthographic structure in college students' perceptual recognition and judgment of letter strings. Lexical status, word frequency, bigram frequency, log bigram frequency, and regularity of letter sequencing were orthogonally varied across a series of experiments. Six-letter words and their anagrams were used as test…

A study investigated the concept of visual memory and its relationship to the spelling process by examining the attempts of a group of Australian elementary school children to spell a selection of words containing silent consonants. Subjects, 360 second, third, and fourth grade students divided into three spelling ability groups, were given 20…
