There is growing evidence that the grammatical errors reflected in the speech of young children are often related to the nature of the input in the ambient language. Although theoretical frameworks differ in the degree to which input plays a role, there is acknowledgment that children require more input than previously assumed to resolve apparent…

We tested four predictions based on the assumption that optional infinitives can be attributed to properties of the input whereby children inappropriately extract non-finite subject-verb sequences (e.g. "the girl run") from larger input utterances (e.g. "Does the girl run?" "Let's watch the girl run"). Thirty children…

Previous studies of children with language impairment (LI) reveal an insensitivity to aspect that may constitute part of the children's deficit. In this study, we examine aspect as well as tense in Hungarian-speaking children with LI. Twenty-one children with LI, 21 TD children matched for age, and 21 TD children matched for receptive vocabulary…

The aim of this study was to determine whether children with specific language impairment (SLI) are sensitive to completion cues in their comprehension of tense. In two experiments, children with SLI (ages 4 ; 1 to 6 ; 4) and typically developing (TD) children (ages 3 ; 5 to 6 ; 5) participated in a sentence-to-scene matching task adapted from…

The aim of this study was to uncover factors accounting for the ability of children with specific language impairment (SLI) to learn agreement morphemes in intervention. Twenty-five children with SLI who participated in a six-month intervention program focused on teaching third person singular -s or auxiliary "is"/"are"/"was" showed a wide range…

Current views on the acquisition of PRO can roughly be divided into two areas: lexical and syntactic accounts. We present data on one verb, "decide," that yields data that not only differs from the data for other similar verbs with the same children, but does not lend itself easily to either type of account. Data from a sentence elicitation task…

A group of preschool-aged children with specific language impairment (SLI), a group of typically developing children matched for age (TD-A), and a group of younger typically developing children matched for mean length of utterance (TD-MLU) were presented with novel verbs in contexts that required them to inflect with past tense "-ed."…

Children ranging in age from 1;1 to 1;3 were presented with 16 contrived lexical concepts, each consisting of a nonsense word (eight object words and eight action words) and four unfamiliar exemplars that served as the referents for that word. Overall, the children used 65% of the experimental words one or more times to refer to at least one of…

Children exhibiting a referential orientation seem more likely to acquire new object names than nonreferentially oriented children. Also, children's selection of words may be influenced by the phonological structure of the words. (Author/RH)

Examined input frequency, sentence position, and duration as contributing factors to grammatical inflections. In parents' conversations with and stories aimed at young children, noun plural inflections were more frequent than third singular verb inflections, especially in sentence-final position. Analysis of four mothers' speech when reading…

The speech of each of eight children aged 15 to 24 months was monitored in an informal setting and analyzed for the imitation of nonsense words introduced by the experimenter. In a second session, objects were introduced as referents for the nonsense words. Results failed to support the two initial hypotheses, namely that children imitate in part…

Presents a critical review of studies designed to teach language production skills to children with specific language impairment. The evidence reviewed suggests that a number of training approaches are effective, often resulting in gains that exceed the rate seen in normal development, provided the speaking situation resembles enough the training…

Describes early word usage in four children aged 1.6 to 1.9. The research investigated the children's use of words whose referents are unknown to them. (Author/AM)

Investigates the role of imitation by children in the acquisition of lexical items and factors influencing word acquisition by imitation. Imitation did not appear to facilitate subsequent spontaneous use of lexical items. Results are discussed in terms of conditions which influence imitative behavior in children. (JMB)

Judgments of utterance appropriateness were examined in three, four, five, and six year olds to examine bases for these judgments in a variety of social contexts. The judgments of the six year olds more closely resembled those of a group of adults, but their judgments were not yet free of some of the factors operative for the younger children.…
