The persistence of individual differences in phonological development of 10 normally developing children observed at age one and again at age three was studied. The children differed considerably in rate of vocabulary acquisition and relative phonological maturity and also in their general approach to learning. (Author/JDD)

Using Locke's 1983 model, analyzes one tendency, consonant use in babbling and early words, and phonological word-selection patterns in 10 children, aged 8 to 16 months. Individual differences were found in all three domains analyzed, with some increase in uniformity across subjects with increasing knowledge of language. (Author/SED)

While the first utterances of the child learning L1 are mostly one-word constructions, many of them are routine words or phrases that the child learns…

A discussion of word acquisition rates and strategies is based upon a 6-month case study of an Estonian-speaking child who gradually and systematically relaxed phonotactic constraints to allow greater complexity in word production. In addition to the cognitive tools of assimilation and accomodation as described by Piaget, the child used a further…
