Examines phonetic variation in multisyllable babbling of infants from 7 to 11 months of age. The investigation was to verify assumptions that, in infant vocal development, there is a systematic increase in the phonetic variation of these babbles, and separate stages of repetitive and nonrepetitive babbling are posited.

This study constitutes the beginning of a longitudinal investigation of phonological development of four children from birth to 2 years. Little variation was found in mean fundamental frequency. Duration, within-utterance range and variability did show developmental change. (RM)

The use of the verbs "go" and "come" was examined in the spontaneous speech of seven two-year-olds. As verbs of motion, the words were used in the context of describing the contour of movement rather than as means of relating end-points of a journey. This is considered crucial in explaining children's difficulty in discriminating the verbs in…

This paper discusses C. Chomsky's 1969 paper on children's syntactic development and the subsequent studies made to test her findings. Later studies indicate that Chomsky's results were not clearly differentiated, and a slight alteration in procedure changes results significantly. (CHK)

Vocalizations of two female infants, recorded over a five-week period after the first emergence of cooing were studied. It was found that the features of the more primitive sound types regrouped themselves in comfort sounds. The implications for theories of prespeech development are discussed. (EJS)

The development of plurals in two German-speaking children was analyzed, based on observational data. It was argued that the children were learning plurals by rote, conditioned by morphological complexity which cannot be subsumed under any general rule. (Author/NCR)

Spontaneous full passives and related constructions from 234 children, aged 2 to 13, and elicited passives from 262 college students were analyzed. The agentive non-reversible did not appear until after age 9; and until age 11 no child produced both reversible and non-reversible passives. (Author/SW)

Focus is one factor that may account for children's use of single-word utterances after they have acquired the use of multi-word utterances. The possible role that focus may play in children's use of single-word utterances in naturalistic settings, after the acquisition of syntax, was investigated. (SW)

Discusses a study that examines which combination of animate and inanimate actors (anyone or anything performing an action) and patients (the thing that is the object of action) two-year-olds view as prototypical. Results suggest that the actor category is usually acquired first for prototypical sentences with animate actors and inanimate…

Describes a study that investigates the order of acquisition of case-marked pronouns in Hebrew among 105 children between two and five years of age. Results indicate that children begin using case-marked pronouns as early as age two and that the stage of morphological development parallels that of English-speaking children. (SED)

The purpose of the paper was to map the language development of children at infant school and examine spontaneous corrections made by the children of their speech. (Author/NCR)

Data on the acquisition of lexical tone were collected from 17 Mandarin-speaking children. Among other results, it was found that: (1) tone is acquired relatively quickly; (2) mastery of tones occurs well before mastery of segmentals; and (3) Mandarin high-level and falling tones are acquired before rising and dipping tones. (Author/RM)

Two studies were conducted to discover possible patterns in question acquisition. For the production study, questions were collected from 22 children aged two to eleven. In the comprehension study, 100 children, aged three to five, were tested. The test controlled syntax and vocabulary and varied specific "wh-" question-words. (Author/RM)

Describes a study that examines the effect of an adult-child discourse structure on the word combination produced by 17 children at the single-word utterance level. There was a significant difference between pretest and posttest multiword production for the experimental group of six children, but no difference for the control group. (SED)

Describes a study of 40 monolingual Spanish-speaking Peruvian children in which comprehension of six locative phrases was tested. Results are analyzed in terms of developmental sequence, locative acquisition, the effects of intrinsic label on projective locative comprehension, the effects of linguistic form, and the effects of context.
