Development of context-sensitive pronunciation in reading: The case of ‹c› and ‹g›.

Writing systems sometimes deviate from one-to-one associations between letters and phonemes, but the deviations are often predictable from sublexical context. For initial ‹c› and ‹g› in English, deviations from the typical /k/ and /g/ pronunciations are influenced by adjacent context (the following vowel, as in center vs. canter) and nonadjacent context (the presence of a Latinate vs. basic suffix, as in gigantic vs. giggling). We conducted two experiments with participants ranging in reading level from early elementary school to university to study the development of context use. Experiment 1 focused on adjacent context, and Experiment 2 also examined nonadjacent context. Use of context developed slowly, and readers at all levels were not as influenced by it as would be expected given the contextual effects in the English vocabulary. We discuss possible reasons for these phenomena and the need to teach children to use context more effectively.
