Previous research has documented that children count spatiotemporally-distinct partial objects as if they were whole objects. This behavior extends beyond counting to inclusion of partial objects in assessment and comparisons of quantities. Multiple accounts of this performance have been proposed: children and adults differ qualitatively in their…

In two visual world experiments we disentangled the influence of order of mention (first vs. second mention), grammatical role (subject vs object), and semantic role (proto-agent vs proto-patient) on 7- to 10-year-olds' real-time interpretation of German pronouns. Children listened to "SVO" or "OVS" sentences containing active…

Children with language disorders have particular difficulty with verbs, but when this difficulty emerges is unknown. We examined syntactic (transitive, intransitive, ditransitive) and semantic (manner, result) features of two-year-olds' verb vocabularies, contrasting late talkers and typically developing children to look for early differences in…

Production studies show that both Russian-speaking children with specific language impairment (SLI) and bilingual children for whom Russian is a non-dominant language have difficulty distinguishing between the near-synonymous connectives "i" "and" and "a" "and/but." "I" is a preferred connective…

This study investigates Mandarin-speaking children's knowledge of event semantics in interpreting spatial modifiers with "zai" 'at' after a posture verb or before a placement verb. The event-semantic principles investigated include subevent modification (Parsons, 1990) and aspect shift (Fong, 1997). We conducted an experimental study…

We aimed to disentangle contributions of socio-pragmatic and structural language deficits to narrative competence by comparing the narratives of children with autism spectrum disorder (ASD; n=25), non-autistic children with language impairments (LI; n=23), and children with typical development (TD; n=27). Groups were matched for age (6½ to 15…

To understand how children develop adult argument structure, we must understand the nature of syntactic and semantic representations during development. The present studies compare the performance of children aged 2;6 on the two intransitive alternations in English: patient ("Daddy is cooking the food"/"The food is cooking")…

For sixty-seven children with ASD (age 1;6 to 5;11), mean Total Vocabulary score on the Language Development Survey (LDS) was 65.3 words; twenty-two children had no reported words; and twenty-one children had 1-49 words. When matched for vocabulary size, children with ASD and children in the LDS normative sample did not differ in semantic category…

We adapted the semantic fluency task into British Sign Language (BSL). In Study 1, we present data from twenty-two deaf signers aged four to fifteen. We show that the same "cognitive signatures" that characterize this task in spoken languages are also present in deaf children, for example, the semantic clustering of responses. In Study…

Pronoun reversal, the use of "you" for self-reference and "I" for an addressee, has often been associated with Autism Spectrum Disorder (ASD) and impaired language. However, recent case studies have shown the phenomenon also to occur in typically developing and even precocious talkers. This study examines longitudinal corpus data from two…

Investigates young children's understanding of homophones in two different linguistic contexts. Results show that the linguistic context is an important factor in young children's understanding of word meaning. (six references) (GLR)

Classifies explicit verbal comparisons in 53 popular children's books both syntactically and semantically. Comparison types found in these books were contrasted with comparisons used as comprehension stimuli in extant developmental research. Implications for the design of future stimulus sets are discussed. (17 references) (GLR)

A study determined what types of speech act five- to 13-year-olds and adults would define as "promising." Results indicate that children could distinguish between "promising" and "predicting" in terms of the speaker's responsibility for the outcome. (Author/CB)

To investigate the apparent delay in color naming by young children, this study compared natural-kind and color naming (and corresponding comprehension) by 48 young English children who completed testing four times over six weeks. Results indicated that, as opposed to the salience view, the apparent delay in color naming may be explained solely on…

Investigated the hierarchical organization of the semantic system in preschoolers with and without word-finding deficits. Children named a series of objects at multiple levels of the noun hierarchy in response to contrast questions. Children with word-finding deficits had similar abilities to the other children but did not have enough stored…
