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…

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…

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)

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)

Complex complements are clausal objects containing tensed verbs (e.g., that she cried) or infinitives (e.g., to cry), following main verbs of communication or mental activities (e.g., say, want). This research examined whether English- and Cantonese-speaking 4-year-olds' complement understanding uniquely predicts their representation of other…
