Developmental Language Disorder as Syntactic Prediction Impairment
We provide evidence that children with Developmental Language Disorder (DLD) are impaired in predictive syntactic processing. In the current study, children listened passively to auditorily-presented sentences, where the critical condition included an unexpected “filled gap” in the direct object position of the relative clause verb. A filled gap is illustrated by the underlined phrase in “ The zebra that the hippo kissed the camel on the nose... …
Case marking and word order in Greek heritage children
This study examined the linguistic and individual-level factors that render case marking a vulnerable domain in English-dominant Greek heritage children. We also investigated whether heritage language (HL) children can use case-marking cues to interpret (non-)canonical sentences in Greek similarly to their monolingual peers. A group of six- to twelve-year-old Greek heritage children in New York City and a control group of age-matched monolingual …
Novel word learning at 21 months predicts receptive vocabulary outcomes in later childhood
Several aspects of early language skills, including parent-report measures of vocabulary, phoneme discrimination, speech segmentation, and speed of lexical access predict later childhood language outcomes. To date, no studies have examined the long-term predictive validity of novel word learning. We examined whether individual differences in novel word learning at 21 months predict later childhood receptive vocabulary outcomes rather than general…

Relative Clause Gap-Filling in Children with Specific Language Impairment
Information level and young children's phonological accuracy
The influence of information level on the production accuracy of 20 children (22 to 28 months) was examined. The data were children's productions of nouns in sets of utterances referring to triplets of pictures representing noun-verb-noun utterances. In each triplet one noun remained the same, thus decreasing in information value from the first to the third picture (new, moderately old, and old information). Words representing new information wer…
Language characteristics of a linguistically precocious child
This study investigated the language skills of a two-year-old child who displayed apparently advanced communication skills. Analysis of 1,258 child utterances in relation to surrounding discourse structures indicated a high functioning level of contingent forms (retrieved forms). Utterances that contained retrieved forms displayed a higher index of language abilities than utterances that lacked such forms. This type of contingent speech elevated …
Attempted sounds are sometimes not
Young children readily acquire new words with consonants and syllable structures already used accurately (IN words). They have more difficulty acquiring new words with consonants or syllable structures never before produced or attempted (OUT words). In the present study, we examined children's acquisition of a third type of word, containing consonants the children had attempted in the past but never produced accurately (ATTEMPTED words). IN, OUT …
Facilitation of early syntax through discourse structure
The effect of an adult–child discourse structure on children's production of word combinations was examined. Seventeen children at the singleword utterance level (1; 5–2; 1) served as subjects. An experimental group of six children were engaged in vertical structures over 10 sessions, while the remaining children served as a control group. Pre-tests and post-tests revealed a significant difference in the number of spontaneous and elicited multiwo…
Examining relationships between input and language development
With various descriptions of adults' speech to children in hand, investigators have turned their attention to questions concerning the specific nature and extent of relationships between aspects of input and language development. Answering such questions requires some conceptualization of the potential relationships that may exist. Equally important, though, are the statistical and design issues surrounding the inference of these relationships. A…
The role of input frequency in lexical acquisition
The influence of frequency of occurrence in input upon early lexical acquisition was examined within an experimental paradigm. Twelve children (1; 0·21 to 1; 3·15) were presented with 16 contrived lexical concepts, each involving a nonsense word and four referents, over ten experimental sessions. Within each concept two exemplars were presented frequently and two were presented infrequently. Overall the children named more frequently presented ex…

The role of action in early lexical acquisition
The role of action in early lexical acquisition was explored in 12 children (1;0.21 to 1;3.15) through the presentation of 16 contrived concepts, each involving a nonsense word and 4 unfamiliar objects or 4 unfamiliar actions. The investigator performed a familiar action on each experimental object. The experimental actions were performed upon more familiar objects. Subjects' productions of these words and performance of these actions indicated t…
Do children pick and choose? an examination of phonological selection and avoidance in early lexical acquisition
The influence of phonological selection and avoidance upon early lexical acquisition was examined within an experimental paradigm. During 10 bi-weekly experimental sessions, 12 children (1;0.21 to 1;3.15 at the outset) were presented with 16 contrived lexical concepts, each consisting of a nonsense word and four unfamiliar referents. For each child, eight words involved phonological characteristics which had been evidenced in production (in) and …
Again and again
The role of a strategy of reduplication in phonological acquisition and behaviour was examined in terms of: (1) the relationship between adoption of this strategy and children's failure to produce nonreduplicated multisyllabic forms and final consonants when attempting corresponding adult models; and (2) the role of the process of reduplication in production constraints. Comparisons of the phonologies of six children (1; 3–1; 9) classified as red…
Some aspects of child phonology in imitative and spontaneous speech
Child phonologists have made varying assumptions concerning the nature of phonological characteristics of children's imitative utterances and their relationship to the characteristics of spontaneous utterances. This study examined this relationship in children in early Stage I. A task was devised which permitted an inspection of children's unsolicited imitations of nonsense words reflecting syllabic shapes and consonants in and out of the child's…
