WHY DETECTING A MISSPELLING IN 'LENGUAGE' IS EASIER THAN IN 'LANGUEGE': SEGMENTAL AND SUPRASEGMENTAL INFLUENCES ON ORTHOGRAPHIC PROCESSING.

Abstract
Four studies were conducted to determine the range of phonological information that can affect orthographic processes during reading under different conditions, and to investigate how the influence of phonology on orthography is affected by other relevant factors, such as linguistic context and individual differences in reading-related skills. Study 1 employed a spelling decision task in which phonemic, lexical stress, and syllabic variables were factorially manipulated in misspelled words. Both phonemes and lexical stress affected the speed and accuracy with which misspellings were detected, indicating that both segmental and suprasegmental phonological information can influence orthographic processing. Study 2 comprised two separate experiments designed to compare phonological effects on orthographic processing in a spelling decision task versus a lexical decision task. Both stress and phoneme effects were reduced in the lexical decision experiment relative to the spelling decision experiment, suggesting that the influence of phonology on orthography is stronger when more extensive phonological processing is required or allowed by a task. Study 3 included two series of analyses examining the roles of phonological feedback and individual differences in Study 2 outcomes. The analyses indicated that better spellers are less sensitive than poorer spellers to the influence of phonological feedback during reading, which supports the hypothesis that phonological feedback is a mechanism for orthographic learning. Study 4 embedded stimuli in a proofreading passage to test the hypothesis that the role of stress in reading is enhanced when upcoming stress patterns can be more easily predicted. Misspellings were detected more often in words misspelled in stressed syllables, and in words that were less predictable from context. Spelling error detection for more predictable words was improved when the misspelling occurred in a stressed syllable. These results were consistent with our hypothesis, and suggest that stress plays a greater role in orthographic processing under more natural reading conditions compared to isolated-word reading. Taken together, these studies suggest that phonological information, including both segmental and suprasegmental phonological information, can affect orthographic processing during reading, and that the influence of phonology on orthography can be moderated by reading task, linguistic context, and individual characteristics of the reader.
