This study employed an artificial language learning paradigm together with a combined behavioral/event-related potential (ERP) approach to examine the neurocognition of the processing of gender agreement, an aspect of inflectional morphology that is problematic in adult second language (L2) learning. Subjects learned to speak and comprehend an…

This paper reports on partial knowledge in two-year-old children's learning of the regular English plural. In Experiments 1 and 2, children were presented with one kind and its label and then were either presented with two of that same kind (A[right arrow]AA) or the initial picture next to a very different thing (A[right arrow]AB). The children in…

The syntactic bootstrapping mechanism of verb learning was evaluated against child-directed speech in Turkish, a language with rich morphology, nominal ellipsis and free word order. Machine-learning algorithms were run on transcribed caregiver speech directed to two Turkish learners (one hour every two weeks between 0;9 to 1;10) of different…

Nativist and constructivist accounts differ in their characterization of children's knowledge of grammatical categories. In this paper we present research on the process of acquisition of a particular grammatical system, gender agreement in the Spanish noun phrase, in children under three years of age. The design of the longitudinal study employed…

Parents of 592 children between the age of 0 ; 8 and 1 ; 4 completed the Estonian adaptation of the MacArthur-Bates Communicative Development Inventory (ECDI Infant Form). The relationships between comprehension and production of different categories of words and gestures were examined. According to the results of regression modelling the…

Numerous studies have proposed that changes of the human language faculty caused by neural maturation can explain the substantial differences in ultimate attainment of grammatical competences between first language (L1) acquirers and second language (L2) learners. However, little evidence on the effect of neural maturation on the attainment of…

Native English speakers tend to exclude regular plural inflection when producing English noun-noun compounds (e.g., "rat-eater" not "rats-eater") while allowing irregular plural inflection within compounds (e.g., "mice-eater") (Clahsen, 1995; Gordon, 1985; Hayes, Smith & Murphy, 2005; Lardiere, 1995; Murphy, 2000). Exposure to the input alone has…

Two experiments investigated the development of fluency in interpreting adjective-noun phrases in 30- and 36-month-old English-learning children. Using online processing measures, children's gaze patterns were monitored as they heard the familiar adjective-noun phrases (e.g. "blue car") in visual contexts where the adjective was either informative…

Noun-class prefixes are obligatory in most Bantu languages. However, the Sotho languages (Sesotho, Setswana, Sepedi) permit a subset of prefixes to be realized as null at the intersection of "unmarked" phonological, syntactic, and discourse conditions. This raises the question of how and when the licensing of null prefixes is learned. Using…

Six tests of the spontaneous speech of twenty-one English-speaking children (1 ; 10 to 2 ; 8; MLUs 1[middle dot]53 to 4[middle dot]38) demonstrate the presence of the syntactic category determiner from the start of combinatorial speech, supporting nativist accounts. Children use multiple determiners before a noun to the same extent as their…

The aim of this study was to uncover factors accounting for the ability of children with specific language impairment (SLI) to learn agreement morphemes in intervention. Twenty-five children with SLI who participated in a six-month intervention program focused on teaching third person singular -s or auxiliary "is"/"are"/"was" showed a wide range…

This study investigates the acquisition of the discourse/pragmatic notion of topic, based on an experimental task eliciting topic vs. focus subjects. In spoken French, these are obligatorily realized as dislocated vs. nondislocated noun phrases. The results provide overwhelming evidence for the early mastery of topic, even by the youngest children…

An eye-movement monitoring experiment investigated readers' response to temporarily ambiguous sentences. The sentences were ambiguous because a relative clause could attach to one of two preceding nouns. Semantic information disambiguated the sentences. Working memory considerations predict an overall preference for the second of the two nouns, as…

This study examines the role of functional morphemes in the earliest stage of lexical development. Recent research showed that prelinguistic infants can perceive functional morphemes. We inquire whether infants use frequent functors to segment potential word forms. French-learning 8-month-olds were familiarized to two utterance types: a novel noun…

In gender-marking languages, the gender of the noun determines the form of the preceding article. In this study, we examined whether French-learning toddlers use gender-marking information on determiners to recognize words. In a split-screen preferential looking experiment, 25-month-olds were presented with picture pairs that referred to nouns…
