Interactive influences on phonological behaviour: a case study

An infant girl's unusual phonological behaviour was evaluated in the light of a maternal model which appeared to exaggerate features of normal conversational speech. It is suggested that parental responses to immature speech patterns may account for selected case study behaviours which have been reported in both the child phonology and child fluency literatures. It appears that evaluation of phonological development within an interactive framework may allow a more accurate picture of the conditions under which children learn speech skills. To this end, further study of the phonetic characteristics of input language and patterns of parental feedback to early articulatory attempts is desirable.
