  • Title: Phonological changes during the transition from one-word to productive word combination.
    Author: Aoyama K, Peters AM, Winchester KS.
    Journal: J Child Lang; 2010 Jan; 37(1):145-57. PubMed ID: 19323858.
    Abstract:
    We investigated developmental changes during the transition from one-word to two-word production, focusing on strategies to lengthen utterances phonologically and to control utterances suprasegmentally. We hypothesized that there is a period of reorganization at the onset of word combinations indicated by decreases in both filler syllables (Fillers) and final syllable lengthening (FSL). The data are from a visually impaired child (Seth) between 1; 6.21 and 1; 10.26. Seth produced many Fillers until 1; 9 when their number decreased for about two weeks after which they changed in nature. FSL was observed until 1; 8, but diminished at 1; 9. These two regressions coincide with the onset of word combination.
