We examined whether children rely on linguistic information (i.e. mass vs. count nouns) or object category information (i.e. objects vs. substances) when they name things. A grinder test was used, in which substances (e.g. water) maintain identity through transformation but objects (e.g. a cup) do not. Thirty children aged three through six were asked if the same name could be used for the same item after transformation. The items included pairs of amorphous substances and discrete objects (e.g. water – a cup), perceptually similar discrete objects (e.g. chalk – a crayon), and food items (e.g. corn – a bean). Children accepted the same name for food, ignoring linguistic information, and for objects, relying on linguistic information. In Experiment 2, 32 children aged five through eight were asked if the same name could be used for unfamiliar hardware and food items after transformation when they were labelled by nonsense mass and count nouns. Children tended to use the same name for food, relying on perceptual information. These results are discussed in terms of the active conceptualization about names of objects in relation to object characteristics.

Theories of language processing differ with respect to the role of abstract syntax and semantics vs surface-level lexical co-occurrence (n-gram) frequency. The contribution of each of these factors has been demonstrated in previous studies of children and adults, but none have investigated them jointly. This study evaluated the role of all three factors in a sentence repetition task performed by children aged 4–7 and 11–12 years. It was found that semantic plausibility benefitted performance in both age groups; syntactic complexity disadvantaged the younger group but benefitted the older group; while contrary to previous findings, n-gram frequency did not facilitate, and in a post-hoc analysis even hampered, performance. This new evidence suggests that n-gram frequency effects might be restricted to the highly constrained and frequent n-grams used in previous investigations, and that semantics and morphosyntax play a more powerful role than n-gram frequency, supporting the role of abstract linguistic knowledge in children's sentence processing.

The ability to distinguish ask and tell in Spanish was studied with five groups of native Spanish speakers: adults, 7- and 10-year-olds in a full-bilingual-programme school (BISO), and 7- and 10-year-olds in a non-total BISO school. The interviews included context-present and context-absent items. Differences in these subjects' responses and those elicited by Chomsky (1969) among children acquiring English are explored. Increased age, bilingual schooling, and presence of contextual clues enhanced performance. Relative difficulty of dile and pregúntale, stages in distinguishing these in three types of constructions, and comparisons of first and second language performance are discussed.

If the logic of natural language negation were classical – a simple matter of true and false – then it would be a disaster to answer a question like Is this essay good? with Yes and no. The overwhelming majority of adults (N = 40) asked to resolve this apparent contradiction were found to do so by appealing to the structure of the essay (e.g. Its thesis was good but its argument was not). Three-year-olds (N = 24), when suitably prepared, also appealed to object structure to resolve a similar apparent contradiction. These results are discussed in relation to a non-classical logical model that can handle object structure.

The process of topicalization occasionally produces pleonasms with nominal-pronominal reduplication (NPR). In these structures the topic nominal is often accompanied by a comment clause containing a pronoun which is co-referential with the topic. This article discusses NPR in the language of children ages seven and nine in four different situations, one of which was child-child in free play, three of which were child-adult in retelling stories, describing pictures, and answering questions. The younger children produced more NPR. Influenced by their attitudes toward their interlocutors, the content of the situations and themselves as communicators, all of the children produced little NPR talking to their peers and increasing amounts talking to adults. Examples are given and analysed.

Garman (1974), reporting on twenty Tamil children aged three to five, postulated a linguistic strategy and two prelinguistic strategies to explain the results of a question-picture choice task involving sentences with embedded and subordinate clauses. In a reanalysis of his data, we identify four processing strategies and show that some of Garman's findings are better explained not as the outcome of prelinguistic strategies but as an artefact of the experimental design. In fact the data provide evidence of a grammatical sensitivity which is consonant with a sensitivity – demonstrated in recent language-acquisition studies – to the branching direction of the language being acquired.

All the comments were thoughtful, interesting, supportive of further investigation into this small but complex arena of language acquisition, and suggested new ways to extend the enterprise. Not having space to discuss all the interesting issues to the length they deserve, I will synthesise the highlights of an overall picture of both agreement and questioning.

Some pronouns can refer to entities that vary widely in scope. In some cases, the referent might be a noun phrase, and in other cases it might be a whole proposition. In the cases of pronouns with a noun phrase antecedent, an already existing referent is reactivated from the preceding context. In the case of pronouns with a propositional antecedent, the referent must be reformulated. The interpretation and use of such pronouns was investigated in 150 eight-year-old children in a reading comprehension task. Experiment 1 used a referent specification task and Experiment 2 used a completion task. It was more difficult for children to process a pronoun when its antecedent was a proposition compared to a noun phrase. These results are in line with the linguistic approaches (e.g., Gundel et al., 2005) according to which processing of pronouns with a propositional antecedent is more complex and requires greater cognitive effort.

Previous studies have demonstrated an effect of early vocal production on infants’ speech processing and later vocabulary. This study focuses on the relationship between vocal production and new word learning. Thirty monolingual Italian-learning infants were recorded at about 11 months, to establish the extent of their consonant production. In parallel, the infants were trained on novel word–object pairs, two consisting of early learned consonants (ELC), two consisting of late learned consonants (LLC). Word learning was assessed through Preferential Looking. The results suggest that vocal production supports word learning: Only children with higher, consistent consonant production attended more to the trained ELC images.

Anticipatory coarticulation is an indispensable feature of speech dynamics contributing to spoken language fluency. Research has shown that children speak with greater degrees of vowel anticipatory coarticulation than adults – that is, greater vocalic influence on previous segments. The present study examined how developmental differences in anticipatory coarticulation transfer to the perceptual domain.

Using a gating paradigm, we tested 29 seven-year-olds and 93 German adult listeners with sequences produced by child and adult speakers, hence corresponding to low versus high vocalic anticipatory coarticulation degrees. First, children predicted vowel targets less successfully than adults. Second, greater perceptual accuracy was found for low compared to highly coarticulated speech. We propose that variations in coarticulation degrees reflect perceptually important differences in information dynamics and that listeners are more sensitive to fast changes in information than to a large amount of vocalic information spread across long segmental spans.

Ravid & Tolchinksy (R&T) introduce an important concept for the field of language acquisition and development: linguistic literacy. To be ‘linguistically literate’, they say, one must possess both ‘knowledge of the two major linguistic modalities – speech and writing’ and ‘a linguistic repertoire that encompasses a wide range of registers and genres’. These two statements make clear the great breadth of research that the authors have considered in formulating their model.

Metaphors are key to how children conceptualise the world around them and how they engage socially and educationally. This study investigated metaphor comprehension in typically developing Arabic-speaking children aged 3;01-6;07. Eighty-seven children were administered a newly developed task containing 20 narrated stories and were asked to point at pictures that best illustrated the metaphoric expression. The results were examined through a mixed ANCOVA, testing the effects of chronological age, metaphor type (primary, perceptual) and metaphor conventionality (conventional, novel) on metaphor comprehension. Children could understand some metaphors just after their third birthday, and their comprehension increased with age. Children’s performance was somewhat better on primary than perceptual, and much better on conventional than novel metaphors. These findings are discussed in light of conceptual metaphor theory (Lakoff & Johnson, 2008) and structure mapping theory (Gentner & Markman, 1997), confirming differences in the acquisition of different metaphor types.

Based on the linguistic analysis of game explanations and retellings, the paper’s goal is to investigate the relation of preschool children’s situated discourse competence and iconic gestures in different communicative genres, focussing on reinforcing and supplementary speech-gesture-combinations. To this end, a method was developed to evaluate discourse competence as a context-sensitive and interactively embedded phenomenon. The so-called GLOBE-model was adapted to assess discourse competence in relation to interactive scaffolding. The findings show clear links between the children’s competence and their parents’ scaffolding. We suggest this to be evidence of a fine-tuned interactive support system. The results also indicate strong relations between higher discourse competence and increased frequency of iconic gestures. This applies in particular to reinforcing gestures. The results are interpreted as a confirmation that the speech-gesture system undergoes systematic changes during early childhood, and that gesturing becomes more iconic – and thus more communicative – when discourse competence is growing.

The present study explored developmental differences in preschoolers’ use of reported speech and internal state language in personal narratives. Three-, four-, and five-year-olds attending a laboratory preschool shared 204 stories about ‘a time when you were happy/sad’. Stories were audio-recorded, transcribed, and coded for reported speech (direct, indirect, narrativized) and internal state language (cognitive states, total emotion terms, unique emotion terms). Personal narratives told by five-year-olds included more cognitive states and more narrativized speech than those told by three- and four-year-olds, even when accounting for children’s vocabulary skills, and that reported speech (narrativized, direct) were positively correlated with cognitive state talk. These findings highlight distinct shifts in children’s use of cognitive state talk and reported speech in personal narratives told at age five. Associations between reported speech and internal state language are both informed by and support Vygotsky’s (1978) fundamental claim that psychological processes are socially mediated by language.

Children who receive cochlear implants develop spoken language on a protracted timescale. The home environment facilitates speech-language development, yet it is relatively unknown how the environment differs between children with cochlear implants and typical hearing. We matched eighteen preschoolers with implants (31-65 months) to two groups of children with typical hearing: by chronological age and hearing age. Each child completed a long-form, naturalistic audio recording of their home environment (appx. 16 hours/child; >730 hours of observation) to measure adult speech input, child vocal productivity, and caregiver-child interaction. Results showed that children with cochlear implants and typical hearing were exposed to and engaged in similar amounts of spoken language with caregivers. However, the home environment did not reflect developmental stages as closely for children with implants, or predict their speech outcomes as strongly. Home-based speech-language interventions should focus on the unique input-outcome relationships for this group of children with hearing loss.
