Examines two issues concerning the acquisition of grammatical morphemes: (1) How is the acquisition of grammatical morphemes influenced by prosodic and phonological characteristics of the language being learned? and (2) What sorts of prosodic and phonological properties do grammatical morphemes have that might aid children in applying particular…

Two experiments investigated the factors that govern children's use of singular and plural forms of count nouns. Experiment 1 used an elicited production task to investigate whether children use referential and/or syntactic information to determine the form of the count nouns when the two sources of information conflict (e.g. "each x, one of the…

Two nonce-word studies examined German-speaking children's productivity with the "Perfekt" (present perfect) from 2;6 to 3;6. The German "Perfekt" consists of the past participle of the main verb and an inflected form of an auxiliary (either "haben" "have" or "sein" "be"). In Study 1, nonce verbs were either introduced in the infinitival form, and…

Children with specific language impairment (SLI) have well-documented problems in the use of tense-related grammatical morphemes. However, in English, tense often overlaps with aspect and modality. In this study, 15 children with SLI (mean age 5;2) and two groups of 15 typically developing children (mean ages 3;6 and 5;3) were compared in terms of…

The purpose of this research was to show how the syntactic and semantic components of the tense-aspect system interact during the acquisition process. Our methodology involved: (1) identifying predicates, (2) finding the initial occurrence of their tense-aspect morphology, and (3) observing the emergence of contrasts. Six children learning Polish…

Examines the relationship between adult recasts of child utterances and the child's acquisition of syntactic structures. Results indicate that maternal recasts of specific morphemes were related to the acquisition of those specific morphemes during certain developmental periods, whereas other grammatical morphemes were facilitated by expansions…

Through discussion and illustrative events, an evolving segment of communication is described during the course of transition of one child's total communication system from the sensorimotor or gestural level at 12 months into the level of use of the adult words "more" and "mine," and associated utterances, at 24 months. (Author/RM)

This study examines the relative contributions of rote-memorization, analogic formation and rule-operation in the production of plurals. Rule-operation was found to be important in that children producing responses characteristic of a given stage did not produce responses for later stages. Contributions of analogic formation and rote-memorization…

Describes a study to determine: (1) the relationship between age and mean length of utterance measured in morphemes (MLU) in a group of normally developing two- and three-year-old chidren; (2) the standard error of MLU; (3) the relationship between MLU and age; and, (4) the ability of MLU to predict children's grammatical development. (SED)

This review analyzes research on acquisition of Hungarian morphology and syntax, specifically, morphological analysis, neologisms, acquisition of first inflections, morpheme order, word order and agreement. Because of Hungarian structure, errors in segmentation of the utterance and the word are minimized. Morphological analysis begins at semantic…

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.…

Three experiments investigated the ability of eight-year old children with poor language comprehension to produce past tense forms of verbs. Twenty children selected as poor comprehenders were compared to 20 age-matched control children. Although the poor comprehenders performed less well than controls on a range of tasks considered to tap…

Describes the presence of a phonological selection strategy and consonant harmony rule in one child's developing phonological system. Evidence suggests that this constant harmony constraint operated across morpheme boundaries, causing a delay in the onset of two-word utterances and influencing the selection of words that could occur in word…

Many recent generativist models attribute grammatical knowledge to young children on the basis that children's language patterns the same way as the target adult language. It has been proposed that the child acquires this knowledge early on in development by a process of parameter setting. Wexler (1996) presents the "Very Early Parameter Setting…

Polysyllabic words from 2 Dutch children from 1;6 to 2;11 were truncated so that they fitted a trochaic (strong-weak SW) pattern, particularly in early samples. Some observations with respect to the (non)realization of determiners suggest an influence of a SW-constraint on the realization of noun phrases. Findings support the hypothesis that words…
