This article analyzes the acquisition of the passive voice in Northern East (NE) Cree and pays particular attention to the interaction of frequency effects and language-specific cues in the way children form and employ expectations, the process of anticipating oncoming structure in the ambient language. The passive has long been of interest in…

This article evaluates the acquisition of directionals in Q'anjob'al, a Western Mayan language of Guatemala. The data come from a longitudinal study of two Q'anjob'al monolingual children of Santa Eulalia, Huehuetenango, Guatemala: Xhuw (1;9-2;5) and Xhim (2;3-3;5). The results show how these children acquire the morphological distribution of…

This article focuses on complex predicates in Qaqet, a Papuan (Baining) language of Papua New Guinea, spoken by 15,000 people and still being acquired monolingually in remote areas. A large part of the Qaqet verb lexicon is compositional, consisting of simple verb roots that combine with prepositions or particles/suffixes, jointly contributing to…

The objective of this study was to examine the development of derivational morphological structures in the productive language of Kuwaiti Arabic (KA)-speaking children. Participants were 512 typically developing Kuwaiti children aged 3;0 years to 7;11 years (243 boys and 269 girls). Five age groups at 1-year intervals were tested; each group was…

It has long been noted that verb phrase (VP) ellipsis cancels the polarity sensitivity of the English Positive Polarity Items (PPIs). In recent work, it has been proposed that words for disjunction are governed by a parameter. On one value of the parameter, disjunction is a PPI for adult speakers of many languages including Mandarin Chinese. On…

Studies of the acquisition of verbs tend to focus on one-verb predicates of the prevalent English type. But in hundreds of languages around the world, multi-verb predicates like serial verb constructions are widely used. It could be reasoned that children should begin producing simple, single-verb predicates before they are able to produce…

This study is based on naturalistic speech samples produced by one child learning Cree as her first language (2;01-4;03) and presents the first investigation into the development of preverbs in the language. Preverbs are an optional class of morpheme which precede the lexical verb stem, dividing into grammatical, lexical and directional (deictic)…

Children's acquisition of directional verbs in sign languages has received a lot of attention, but less is known about the sociocultural process of using these verbs, especially in the context of emerging sign languages in diverse language ecologies. Directional verbs are a common grammatical phenomenon of many sign languages in which some verbs…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

While previous work on postverbal subjects in Italian has shown that young children are sensitive to the effects of argument structure and definiteness, little is known about the acquisition of postverbal subjects at the VP-periphery. In response, the present study investigated such subjects under new-information focus by monolingual Italian…

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…

The present study examines the development of the earliest type of complex predicates to emerge in child Hebrew -- extended predicate constructions. These constructions take the form of a modal/aspectual operator followed by an infinitival verb form (e.g., "roce lesaxek" 'want to.play'), and since they serve various discursive functions…

The delayed acquisition of Spanish "ser" and "estar" is generally understood as rooted in the cognitive demands imposed by the integration of semantic-pragmatic and world-knowledge factors associated with their lexical meanings. Here we ask (1) what is the nature of this language world-knowledge integration? and (2) what is the…

The acquisition of verb morphology is often studied using categorical criteria for determining the productivity of a morpheme. Applying this approach to Japanese, an agglutinative language, this study finds no consistent order for morpheme acquisition and that productivity could be explained by sampling effects. To examine morpheme acquisition…

This article examines the input to Argentinian Spanish-learning children from low and middle socioeconomic status (SES). It aims to determine whether the vocabulary composition (nouns and verbs) of their input varies as a function of SES, the addressee and other contextual variables such as the type of activity and the pragmatic orientation of the…
