Abstract

Protracted Phonological Development (PPD) features phonological patterns that persist beyond expected during development, decreasing intelligibility (Dubasik & Ingram, 2013). This study aims at describing the phonological patterns in Chilean children (3.0 to 3.11 years of age) with PPD, within the Nonlinear Phonology background. This objective sprung from the need to study the suprasegmental and segmental patterns of Chilean children with PPD, given that no research has been conducted based on the Nonlinear Theory among Chilean children. The sample consisted of 5 Chilean children. They had all been diagnosed with PPD and attended kindergartens in Valparaíso, Chile. These children were administered the Spanish Word List, which allowed to obtain a corpus of 500 words. The corpus was later analyzed by means of the suprasegmental measures: i.e.: Whole Word Match (WWM), Word Shape Match (WSM) and segmental measures, expressed in Percentage of Correct Consonants (PCC). Results showed that these children with PPD performed high on accent patterns (99.2%), but at deficit levels on the WWM measures (with 52.2% of correct answers), on the WSM measures (with 73.4%), and on PCC measures (with 89.2%). Consequently, this research provides empirical evidence regarding suprasegmental and segmental alterations in children with PPD, since the values herein obtained are not aligned with the Typical Development (TD) observed in other studies.
