In a seminal study, Cameron-Faulkner et al. made two important observations about utterance-level constructions in English child-directed speech (CDS). First, they observed that canonical in/transitive sentences are surprisingly infrequent in child-direct speech (given that SVO word order is often thought to play a key role in the acquisition of…

The acquisition of quantifiers is a central topic in cognitive science. The present study investigated the emergence, frequency, and non-target-like production of the universal quantifiers "all," "every," and "each" in child English from a linguistic perspective, based on the data from longitudinal naturalistic…

While monolingual English speakers acquire most pronouns by age 5, acquisition amid prevalent, normative code-mixing, such as in Trinidad, is underexplored. This study examines how Trinidadian 3- to 5-year-olds express third-person subject, object, reflexive and possessive pronouns and factors influencing pronoun choices. Seventy-five preschoolers…

This study investigates the influences of early and intense L2 exposure on children's L1 causative verb production, assessed by an experimental causative verb production task. Turkish expresses causality by morphological and lexical means, whereas English does so by periphrastic and lexical means. Learning L2 English might enhance L1 Turkish…

Polish and English differ in the surface realization of the underlying Determiner Phrase (DP): Polish lacks an article system, whereas English makes use of articles for both grammatical and pragmatic reasons. This difference has an impact on how referentiality is rendered in both languages. In this article, the authors investigate the use of…

During narration, speakers constantly choose appropriate referential forms (nominals or pronominals). Children may engage in this reference marking differently than adults. Discourse- or listener-oriented approaches make different predictions about referential behaviour in cognitively demanding situations: the first predicts a higher number of…

Complex systems of inflectional morphology provide a useful testing ground for input-based language acquisition theories. Two analyses were performed on a high-density (12%) naturalistic sample of two Polish-English children's (2;0 and 3;11) and their parents' use of Polish noun inflection: first, each child's use of inflectional affixes and their…

In this corpus study, it is asked whether young children speaking European French build their early syntax around grammatical or lexical words. Specifically, the study examines the relationship of grammatical and lexical words in three types of syntactic structures (determiner--noun, pronoun--verb and subject pronoun--verb). The corpus included…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

Although a considerable number of studies have shown D(eterminer) elements, i.e. determiners and pronominal clitics, to be particularly vulnerable to impairment in monolingual children with Developmental Language Disorder (DLD), little is known about the use of appropriate or/and grammatically correct referring expressions in the children's…

The early use of first and second person pronouns has been viewed as a sign of emerging social understanding. However, it may also depend on general language development: pronouns do not appear among the first words children acquire. In addition, some languages conjugate verbs for person, and the inflections may thus show similar relations to…

The syntactic structure of sentences in which a new word appears may provide listeners with cues to that new word's form class. In English, for example, a noun tends to follow a determiner ("a"/"an"/"the"), while a verb precedes the morphological inflection [ing]. The presence of these markers may assist children in…

Imageability is the ability of words to elicit mental sensory images of their referents. Recent research has suggested that imageability facilitates the processing and acquisition of inflected word forms. The present study examined whether inflected word forms are acquired earlier in highly imageable words in Czech children. Parents of 317…

Request for information (RfI) is believed to be the universally dominant function of young children's questioning, whereas request for action (RfA) has been reported to be the leading interrogative form used in early child Cantonese. The possibility of crosslinguistic variability prompts further research and comparison with additional languages.…

The study investigates acquisition of verb inflections by four monolingual Hebrew-acquiring children from middle-class backgrounds, audio-recorded in longitudinal, weekly samples at a mean age-range of between 18 and 26 months. Productive use of inflectional morphology is shown to manifest increasing structural specification, as a function of…
