We examined whether and how the degree of meaning overlap between morphologically related words influences sentence plausibility judgment in children. In two separate studies with kindergarten and second-graders, English-speaking and French-speaking children judged the plausibility of sentences that included two paired target words. Some of these word pairs were morphologically related, across three conditions with differing levels of meaning overlap: low (wait-waiter), moderate (fold-folder) and high (farm-farmer). In another two conditions, word pairs were related only by phonology (rock-rocket) or semantics (car-automobile). Children in both ages and languages demonstrated higher plausibility scores as meaning overlap increased between morphologically related words. Further, kindergarten children rated sentences that included word pairs with phonological overlap as more plausible than second-grade children, while second-grade children rated those with high meaning overlap as more plausible than kindergarten children. We interpret these findings in light of current models of morphological development.

The Sentence Structure sub-test (SST) of the Clinical Evaluation of Language Fundamentals (CELF) aims to “measure the acquisition of grammatical (structural) rules at the sentence level”. Although originally designed for clinical practice with monolingual children, components of the CELF, such as the SST, are often used to inform psycholinguistic research. Raw scores are also commonly used to estimate the English proficiency of bilingual children. This study queries the reliability of the SST as an index of children's ability to deal with structural complexity in sentence comprehension, and demonstrates that cognitive complexity induces a considerable confound in the task, affecting 5- to 7-year-old monolinguals (n = 87) and bilinguals (n = 87) alike.

While adult studies show that consonants are more important than vowels in lexical processing tasks, the developmental trajectory of this consonant bias varies cross-linguistically. This study tested whether British English-learning 11-month-old infants’ recognition of familiar word forms is more reliant on consonants than vowels, as found by Poltrock and Nazzi (2015) in French. After establishing that infants prefer listening to a list of familiar words over pseudowords (Experiment 1), Experiment 2 examined preference for consonant versus vowel mispronunciations of these words. Infants listened to both alterations equally. In Experiment 3, using a simplified version of the task with one familiar word only (‘mummy’), infants’ preference for its correct pronunciation over a consonant or a vowel change confirmed an equal sensitivity to both alterations. British English-learning infants’ word form recognition appears to be equally impacted by consonant and vowel information, providing further evidence that initial lexical processes vary cross-linguistically.

This research addressed the question of whether children understand proper names differently from descriptions. We examined how children extend these two types of expressions from an initial object (a truck) owned by the experimenter to two identical objects created by transforming the initial object, both owned by the experimenter. Adults and 5/6-year-olds extended a name (“Tommy”) to only one post-transformation object, but extended a description (“my truck”) to both objects. Adults and 7-year-olds (but not 5/6-year-olds) also extended a description modeled as a name (“called My Truck”) to only one object. Like adults, children understand that proper names identify unique individuals, but that descriptions identify properties.

The present study investigates the production and comprehension of indefinite and definite articles as markers of givenness by typically-developing German-speaking children, from the perspective of information structure theory. The study involves 93 typically-developing children aged four to seven years old with normal language-skills and 20 adults. The results of a story-narration task and a truth-value judgment task reveal that children have more problems with new than with given referents in production as well as comprehension suggesting a “given better than new”-pattern. These findings are explained in the context of perspective-taking capacities and cue weighting theory.

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.

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.

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.

MacWhinney (2004) has provided a clear and welcome synthesis of many strands of the recent research addressing the logical problem of first language acquisition from a non-nativist or non-generative grammar framework. The strand that I will comment on is the one MacWhinney calls the ‘pivot’ of his proposal, namely, that acquiring a grammar is primarily a function of learning ITEM-BASEDPATTERNS (e.g. pp. 23–29, 41, passim). These item-based patterns serve a number of dominant roles within MacWhinney's proposal, including enforcing children's conservatism (thereby reducing greatly their overgeneralizations and need to recover from the same), supporting the probabilistic nature of grammar, and enabling the competition that promotes recovery from the overgeneralizations that do occur. My concern here is primarily with the first role, that of enforcing children's conservatism, and especially with the exclusive use of language PRODUCTION as the demonstrated support of this conservatism.

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.

We examined the size, content, and use of evaluative lexis by 26 English monolingual and 20 Spanish–English bilingual 30-month-old children in interaction with their mothers. We extracted the evaluative words, defined as words referring to cognition, volition, or emotion. Controlling for overall vocabulary skills as measured by the MacArthur-Bates inventories, monolinguals had a larger evaluative lexicon than the bilinguals’ Spanish evaluative lexicon, but no difference was found between monolinguals’ and bilinguals’ English evaluative lexicons. There were differences between the monolinguals and bilinguals in the distribution of evaluative words across semantic categories: English monolingual children used more words pertaining to volition and cognition and talked more about volition than the Spanish–English bilingual children. These results suggest that the development of evaluative lexicons is influenced by cultural differences, and consequently, bilingual children, who are also bicultural, follow a different developmental path in both languages from the path followed by their monolingual peers.

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.

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.
