Learning to read with underdeveloped phonemic awareness but lexicalized phonological recoding: a case study of a 3-year-old

Case studies on very precocious readers are useful for examining what sources of knowledge and processes are necessary in the acquisition of reading. This is a case study of a 40-month-old child with a word reading age of 8 years 6 months. Tests indicated that she had no phoneme awareness beyond initial phonemes, and that her productive spelling was undeveloped. In reading she was highly proficient at rapid phonological recoding, both by correspondences that were contextually sensitive and those that were not. The former determined her high level of irregular pronunciations for irregular consistent non-words. Experiments indicated that she had well-specified orthographic lexical representations. It was concluded that her phonological recoding was an implicit process based on sublexical relations induced from her lexical representations rather than explicitly taught letter-sound correspondences. The implications of the results for major developmental models of reading acquisition are examined.
