The Role of Utterance Length and Position in 3-Year-Olds' Production of Third Person Singular -s

摘要

Purpose: Evidence from children's spontaneous speech suggests that utterance length and utterance position may help explain why children omit grammatical morphemes in some contexts but not others. This study investigated whether increased utterance length (hence, increased grammatical complexity) adversely affects children's third person singular -s production in more controlled experimental conditions.
