Reduplication Revisited

Functions, Constraints, Repairs, and Clinical Implications

This case study considers the phonological forms of early lexical items produced by 1 normally developing boy, from 19 to 22 months of age, who began to produce all monosyllabic words as bisyllabic. In order to link this empirical data (the apparent creation of increased complexity) with universal tendencies (motivated by the reduction of complexity), the functions of reduplication were revisited. Phonological processes (i.e., reduplication and final consonant deletion) are viewed as repairs motivated by 2 interacting constraints (i.e., constraints on monosyllabic words and on word-final consonants). These longitudinal case study data provide further evidence for a relationship between final consonant deletion and reduplication. A possible treatment approach for similar patterns demonstrated clinically is recommended.
