Early Phonological Development: Creating an Assessment Test
This paper describes a new protocol for assessing the phonological systems of two-year-olds with typical development and older children with delays in vocabulary acquisition. The test (Profiles of Early Expressive Phonological Skills (PEEPS), ) differs from currently available assessments in that age of acquisition, based on lexical norms from the MacArthur-Bates Communicative Developmental Inventories, served as the primary criterion for creating a word list. Phonetic and semantic properties of the words were also considered in selecting items for the test. Productions of words using the PEEPS protocol have been gathered from a group of children with typical development and another group with cleft lip and/or palate. By 24 months of age, the children with typical development produced more than 90% of the target words and the children with atypical development produced 73% of the words. Regarding administration, the time needed for administering the protocol decreased with age.
