This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of…

Adults create and update predictions about what speakers will say next. This study asks whether prediction can drive language acquisition, by testing whether 3- to 4-year-old children (n = 45) adapt to recent information when learning novel words. The study used a syntactic context which can precede both nouns and verbs to manipulate children's…

This study examines whether children's decontextualized talk--talk about nonpresent events, explanations, or pretend--at 30 months predicts seventh-grade academic language proficiency (age 12). Academic language (AL) refers to the language of school texts. AL proficiency has been identified as an important predictor of adolescent text…

Variability in children's language acquisition is likely due to a number of cognitive and social variables. The current study investigated whether individual differences in statistical learning (SL), which has been implicated in language acquisition, independently predicted 6- to 8-year-old's comprehension of syntax. Sixty-eight (N = 68)…

Recent evidence has suggested that sleep may facilitate language learning. This study examined variation in language ability in 29 toddlers with Down syndrome (DS) in relation to levels of sleep disruption. Toddlers with DS and poor sleep (66%, n = 19) showed greater deficits on parent-reported and objective measures of language, including…

Two-year-olds use the sentence structures verbs appear in--"subcategorization frames"--to guide verb learning. This is syntactic bootstrapping. This study probed the developmental origins of this ability. The structure-mapping account proposes that children begin with a bias toward one-to-one mapping between nouns in sentences and participant…

In two studies, two year olds learned a novel word for a particular stuffed animal. When the animal was familiar, children interpreted the novel word as a proper noun. When the animal was unfamiliar, children frequently interpreted the novel word as a count noun referring to a kind of object. (BC)

Three experiments presented nonsense verbs to two-year-olds either in syntactic isolation or embedded within a transitive syntactic frame. Found that children had identifiable action biases in the absence of syntactic information and that these biases were shifted by the addition of a transitive syntactic frame. (MDM)

This study examined the relationship between syntax discrimination and other language skills with 50 children each in kindergarten, first grade and second grade. Also, the children were asked to imitate and show comprehension of normal and scrambled grammar sentences. (Author/JH)

The Developmental Sentence Scoring (DSS) procedure was used to collect normative information about the syntax development of male and female children. (SB)

Results indicate that at least three factors contribute to the linguistic complexity of "wh-questions" and help to determine sequence of acquisitions: the syntactic function of the individual "wh-forms," the relative semantic complexity of different verbs, and contingency relations in discourse. (MP)

Investigates whether patient animacy affected the acquisition of the passive construction of syntax of 32 children aged two-five years. Results indicate that children who were taught the passive with animate patients produced more passives in the teaching phase than did comparable children who received inanimate patients. (RJC)

Samples of the language used by 4 children were recorded longitudinally between 1.5 and 3 years of age. Children's expressions of motion were categorized into expressions involving a source, path, or goal of motion. There were developmental changes, including an increase in the use of words relating to goals as children grew older. (BC)

English- and Japanese-speaking children aged four and five were asked to say the opposite of statements. Statements varied in truth value and unmarked/marked membership of antonym pairs. Findings did not support a universality hypothesis; differences were found between the two groups in the use of semantic and syntactic denial. (Author/CB)
