The research presented in this paper aimed to serve two purposes. First, the objective was to understand the relationship between lexical and grammatical spelling. In this way, we studied how the frequency and consistency of verb interacted with the application of grammatical rules. Second, we investigated the dynamics of spelling during the…

The authors define two mathematical cognitive verbs which are fundamental to the development of mathematical thinking and reasoning. They distinguish between 'describing' and 'explaining' in relation to doing mathematics, rather than using them interchangeably.

It has been well-documented that although children around 4 years start to attribute false beliefs to others in classic false-belief tasks, they are still less able to evaluate the truth-value of propositional belief-reporting sentences, especially when belief conflicts with reality. This article investigates whether linguistic cues, verb…

Understanding how a child's language system develops into an adult-like system is a central question in language development research. An increasingly influential account proposes that the brain constantly generates top-down predictions and matches them against incoming input, with higher-level cognitive models serving to minimize prediction…

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…

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…

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

Arabic is characterized by diglossia, which involves the use of two language varieties within a single speech community: Spoken Arabic (SpA) for everyday speech and Modern Standard Arabic (MSA) for formal speech and reading/writing. Earlier research suggests that some Arabic-speaking children with Autism spectrum disorder (ASD) might favor MSA…

This study addresses the question of how the main factors related to input--including the environment in which children are exposed to both languages, the relative timing of the onset of the exposure to them and the amount of input--affect bilingual language acquisition at primary-school age. We examined the data of 42 German Polish bilinguals who…

Italian relative clauses like "Il bambino che bacia la mamma" 'the child that kisses the mom' are ambiguous between a subject reading and an object reading with postverbal subject. However, the latter is scarcely accessible for word order and theory-internal considerations. This study aims at investigating the role of semantic…

Previous research indicates that the development of mood selection in Spanish spans several years and ends in the mastery of mood selection with sentential complements to express complex semantic meanings. The present study investigates this underexplored late stage by examining how Spanish-speaking children acquire adultlike mood selection in…

Two studies examined the role of input distribution in English construction learning, by child learners from a Mandarin first-language background, and the extent to which phonological short-term memory and awareness predicted such learning. In the first study, 4th-grade students of Mandarin Chinese (N = 121) learned the English object-cleft…

The present study explores discourse and long-term effects of structured input (SI) and structured output when delivered in isolation or in combination on the acquisition of the English causative. Research investigating the effects of SI has indicated that it is the causative variable in the positive effects of processing instruction. To provide…

Purpose: We investigated four theoretically based latent variable models of word learning in young school-age children. Method: One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and…

The present study aims at exploring: (a) the role of the educational setting in the acquisition of aspect and executive functions (i.e. updating) skills, (b) the acquisition of the aspectual features in Greek-German bilingual children and (c) the impact of updating on the acquisition of aspect. Imperfective aspect has been found to be acquired…
