A longitudinal study, intended to produce a profile of the relationship between cognitive, social, and linguistic development in Danish children, had as subjects a boy and a girl aged 11 and 8 months, who were observed until they reached age 3. Naturalistic language used by the children and their parents, videotaped during regular visits, was…

A study of the awareness of verb transitivity in the spontaneous speech of two two-year-old native speakers of Quiche was accomplished by examining three factors: transitive terminations given to verbs, subject markers on the verbs, and syntax.

Two experiments were conducted on the use and combination of three cues that differentiate active from passive verbs: a form of the auxiliary "be," the morphology of the passive participle of the verb, and the case-making preposition "by." In the first experiment, 59 children aged 2.9 to 5.10 years were asked to interpret sentences with one, two,…

A study of the late acquisition of the passive in Zulu used data from transcripts of naturalistic speech gathered in a longitudinal study of several children's speech development between 1.10 and 3.6 years of age. It was hypothesized that the productivity of the passive construction in Zulu is a factor facilitating acquisition. A range of…

Two studies examined the development of major properties of reflexives and pronouns in English language acquisition by applying the theory of binding of reflexives and pronouns to potential antecedents in the sentence. The children ranged in age from 2.6 to 6.6 years. In the first experiment, the children were presented with two pictures and were…
