The gender and number of a direct object clitic pronoun are based on the gender and number of the noun to which it refers. Grammatical gender is an intrinsic property of the lexical item that is independent from the natural sex of referents, whereas number is a non-intrinsic feature of nouns based on the conceptual level of quantity. The aim of…

A fundamental question in language acquisition research is whether young children have abstract grammatical representations. We tested this question experimentally. French-learning 30-month-olds were first taught novel word-object pairs in the context of a gender-marked determiner (e.g., un[subscript MASC]ravole "a ravole"). Test trials…

Purpose: The authors studied the effect of the cochlear implant (CI) on language comprehension and production in deaf children who had received a CI in the 2nd year of life. Method: The authors evaluated lexical and morphosyntactic skills in comprehension and production in 17 Italian children who are deaf (M = 54 months of age) with a CI and in 2…

Recent evidence from adult pronoun comprehension suggests that semantic factors such as verb transitivity affect referent salience and thereby anaphora resolution. We tested whether the same semantic factors influence pronoun comprehension in young children. In a visual world study, 3-year-olds heard stories that began with a sentence containing…

Two recent papers (de Villiers & Johnson, 2007; Johnson, de Villiers & Seymour, 2005) have claimed that children have difficulty with verbal "-s" until five- six-years-old. This contrasts with perceptual studies showing evidence for sensitivity to the grammatical properties of verbal "-s" as young as 1;4. These apparently conflicting findings can…

This paper presents a large-scale cross-sectional study of Danish children's early language acquisition based on the Danish adaptation of the "MacArthur-Bates Communicative Development Inventories" (CDI). Measures of validity and reliability imply that the Danish adaptation of the American CDI has been adjusted linguistically and culturally in…

In an experiment investigating aspects of children's comprehension of sentences containing the connective "if," young children judged correct and reversed "Y if X" and "If X, Y" sentences as "sensible" or "silly." The comprehension of the role of "if" in sentences appears to be a…

Describes early word usage in four children aged 1.6 to 1.9. The research investigated the children's use of words whose referents are unknown to them. (Author/AM)

Viewing language acquisition as the product of a biased learner who takes advantage of the information available from a variety of sources in his or her environment, this book provides a new way of thinking about the process of language comprehension. The analysis in the book borrows insights from theories about the development of mental models,…

Three experiments on the comprehension and acquisition of temporal terms are described. Methodological innovations were applied to control for possible methodological effects on children's performance. Each experiment involved 24 children aged 3 to 5. In the first experiment, subjects manipulated toys in response to instructions containing the…

Based in part on an Indiana University doctoral dissertation; segments presented to the Midwestern Psychological Association, Cincinnati, Ohio, 1970. Research supported by a National Science Foundation Graduate Traineeship, a Public Health Service Predoctoral Research Fellowship to the author, and a Public Health Service Research Grant to Richard…

Thirty children with a mean length of utterance ranging from 1.00 to 4 and an age range of 1.7 to 5.5 were tested for comprehension of two-noun possessive phrases. Three types of possessive relationships were used to uncover children's knowledge of the semantics and syntax of English possession. (Author/AM)

Preschool children aged 2.6 to 5.0 were presented with reversible active and passive sentences in four comprehension test settings. The children's response patterns were analyzed in terms of individual response patterns. Extralinguistic cues accounted for the most common patterns. (Author/AM)

Investigated whether children age 2; age 0-2; and 2 years used grammatical and caregiver cues in sentence comprehension and how different types of cues interacted. Children listened to sentences and identified pictures. Results indicated that children used caregiver cues (e.g., short length and position of key words) in sentence comprehension.…

Ten objects were used to assess comprehension, production, and imitation of comparative and superlative suffixes in 100 children ranging in age from two years, six months, to four years, six months. (Author/AM)
