Phonological processes have been used to describe children’s speech for a number of years, but the causes of most processes remain unexplained. In a study investigating possible sources of processes in children’s speech, Aitchison and Chiat (1981) suggested that many developmental phonological processes may be a result of problems in lexical storage and retrieval. One limitation of their study, however, was that they had no adult control group, whose results might have helped clarify their findings. The present research with adults was similar to Aitchison and Chiat’s investigation with children and was intended to provide additional information about whether children’s typical phonological processes generally involve lexical storage and recall difficulties. Caution is advised in assuming that children’s spontaneous phonological processes are generally a result of lexical storage and recall factors.
