ABSTRACT

It is important to consider children’s whole-word productions as a measure of phonological development. The purpose of this study is to estimate whole-word abilities in two-year-old children. Four measurements to look at whole-words were proposed: the proportion of whole-word correctness (PWC); the phonological mean length of utterance (PMLU); the proportion of whole-word proximity (PWP); and the proportion of whole-word variability (PWV). Approximately 40-50 minutes of communication data were collected for each child using play materials and picture cards. The results were as follows: First, PWC is mean .43; PMLU is mean 6.60; PWP is mean .85; and PWV is .40. Second, there were high positive correlations between the percentage of consonants correct (PCC) and PWC, PMLU, PWP, but negative correlations between PCC and PWV. Third, there were corrections between all measurements. These measures were relatively easy to apply and should prove to be highly valid and reliable. Fourth, suggested stage by Ingram (2000) is to develop a means to place children into phonological developmental stages based on their whole-word productions. The PMLU score of target words places in stage Ⅴ.
