Abstract
What are the cognitive/linguistic mechanisms necessary for the literate adult to spell a familiar word accurately or to attempt to spell an unfamiliar word or pronounceable nonword? In developing a model of single word/nonword spelling, one might postulate that accurate spelling can be accomplished solely by means of access to a system of rules specifying which graphemic units are assigned to component phonemic units of a phonological sequence. This phoneme-grapheme conversion system, used for phonologically assembled spelling, would, however, only allow for accurate spelling of pronounceable nonwords since any phonologically plausible spelling on a nonword is considered accurate. Reliance on this system for assembling spelling of words, however, is quite problematic. This is due to the opaque relationship between phonemes and their graphemic realisations in English. Thus, for example, the word /kot/ could be misspelled as “cote,” “kote,” “koat,” etc. by use of phonemegrapheme correspondence mappings (see Morton, 1980; Ellis, 1982). The point is that while any phonologically plausible spelling for a nonword is considered accurate, any phonologically plausible spelling for a word just won’t do. In order to spell all English words accurately, one needs to have access to a lexical system containing whole-word spelling representations (i.e., a graphemic output lexicon). That is, the unique spelling for each word must be addressed in this system. Since pronounceable nonwords do not have entries in the graphemic output lexicon, they can only be provided a phonologically plausible spelling (in this type of cognitive architecture) by use of the nonlexical phoneme-grapheme conversion system.
