Usage-based account of the acquisition of liaison: Evidence from sensitivity to the singular/plural orientation of nouns

Abstract

This study investigates whether children’s production and recognition of obligatory liaison sequences in French depend on the singular/plural orientation of nouns. Certain nouns occur more frequently in the plural (e.g., arbre “tree”), whereas others are found more often in the singular (e.g., arc-en-ciel “rainbow”). In the input, children more frequently encounter these plural-oriented nouns after determiners that indicate plurality (e.g., les, des “the”, deux “two”) and that are often associated with a /z/ liaison (e.g., deux arbres [døzarbr] “two trees”). In Experiment 1, 122 children (3 years 2 months to 6 years 3 months of age) were asked to produce nominal phrases with either /z/ liaisons (i.e., in plural contexts such as deux ours [døzurs] “two bears”) or /n/ liaisons (i.e., in singular contexts such as un ours [ œ ˜ nurs] “one bear”). We found correlations between the plural orientation of the nouns and (a) the probability that they will be preceded by an incorrect /z/ liaison in the singular context and (b) the probability that they will be preceded by a correct /z/ liaison in the plural context. This result was, however, restricted to the younger children. In Experiment 2, 20 children (5 years 5 months to 6 years 3 months of age) were asked to monitor target words in auditorily presented sentences. The results showed shorter reaction times for singular-oriented nouns when preceded by a singular determiner than when preceded by a plural determiner. Conversely, plural-oriented nouns were responded to faster when preceded by a plural determiner than when preceded by a singular determiner. Results are discussed within the framework of a two-stage model of liaison acquisition recently proposed by Chevrot, Chabanal, and Dugua ( Journal of French Language Studies, 17 [2007] 103–128) as well as by Chevrot, Dugua, and Fayol ( Journal of Child Language [in press]).
