“…Because young children do not exhibit the same sensitivity to phonetic detail that adults do, researchers have suggested that children store words holistically, perhaps in terms of prosodic structure and/or overall acoustic shape or perhaps in terms of some coarsely defined phonetic features (e.g., Ferguson & Farwell, 1975;Treiman & Baron, 1981). Some researchers have posited that childrenÕs lexical representations are stored holistically only until the onset of the vocabulary spurt at approximately 19 months of age (Ferguson, 1986;Ferguson & Farwell, 1975;Locke, 1988;Menyuk & Menn, 1979;Studdert-Kennedy, 1986). Others have argued that holistic lexical representations continue throughout early childhood until the lexicon is restructured as either a precursor to or a consequence of learning to read 1 (e.g., Fowler, 1991;Jusczyk, 1986;Metsala & Walley, 1998;Treiman & Baron, 1981;Walley, 1993).…”
