An important issue in theories of word learning is how abstract or context-specific representations of novel words are. One aspect of this broad issue is how well learners maintain information about the source of novel words. We investigated whether listeners' source memory was better for words learned from members of their in-group (students of…

Listening comprehension is a real-time process, yet very little is known about the variables affecting real-time second language (L2) listening. The present study aimed at investigating the effects of syntactic complexity and word frequency on L2 listening. Furthermore, the role of the listener's working memory capacity in listening comprehension…

Models of language learning often assume that we learn from all the input we receive. This assumption is particularly strong in the domain of short-term and long-term grammatical convergence, where researchers argue that grammatical convergence is mostly an automatic process insulated from social factors. This article shows that the degree to…

This article reports the results of the first longitudinal study that systematically investigates the acquisition of verb agreement by hearing learners of a sign language. During a 2-year period, 14 novel learners of Sign Language of the Netherlands (NGT) with a spoken language background performed an elicitation task 15 times. Seven deaf native…

Bilingual children are often exposed to non-native speech through their parents. Yet, little is known about the relation between bilingual preschoolers' speech production and their speech input. The present study investigated the production of voice onset time (VOT) by Dutch-German bilingual preschoolers and their sequential bilingual mothers. The…

In 3 ERP experiments, we investigated how experienced L2 speakers process natural and correct syntactic input that deviates from their own, sometimes incorrect, syntactic representations. Our previous study (Lemhöfer, Schriefers, & Indefrey, 2014) had shown that L2 speakers do engage in native-like syntactic processing of gender agreement but…

This study investigates the pitch properties of infant-directed speech (IDS) specific to word-learning contexts in which mothers introduce unfamiliar words to children. Using a semi-spontaneous story-book telling task, we examined (1) whether mothers made distinctions between unfamiliar and familiar words with pitch in IDS compared to…

This study examined the quantity and quality of parental linguistic input to toddlers with moderate hearing loss (MHL) compared with toddlers with normal hearing (NH). The linguistic input to eighteen toddlers with MHL and twenty-four toddlers with NH was examined during a 10-minute free-play activity in their home environment. Results showed that…

Infants are thought to be sensitive to frequency in the input as a cue for phonological development. However, linguistic biases such as phonological markedness have been argued to play a role too. Since frequency and markedness are correlated, the two assertions could be different interpretations of data that confound frequency and markedness. In…

How does phonological development differ in children exposed to one versus two variants of a single language? If children receive mixed evidence for a phonological contrast (i.e., one language variant in the environment maintains a contrast while another neutralizes it), will they treat this contrast as noncontrastive (i.e., as allophonic)? Or…

The aim of this study was twofold: first, to develop an experimental technique as a tool to investigate learning outcomes of spontaneous, naturalistic second language (L2) learning under controlled laboratory conditions; and second, to explore how this technique can be used to understand the basic conditions and limits of this learning. Two…

This article aims to investigate how Dutch children may eventually converge on a targetlike distribution of "hoeven" 'need,' a modal verbal NPI (Negative Polarity Item), based on its appearance in the scope of merely some but not all of its possible licensers in the language input (i.e., the induction problem). Imitation performance was…

In recent years, a surging uptake of content and language integrated learning (CLIL) has permeated the European context. This article presents the outcomes of a study about the self-reported pedagogical practices of CLIL teachers in the Netherlands. To investigate these teachers' pedagogies, a questionnaire was designed, validated and,…

The ability to detect non-adjacent dependencies (i.e. between "a" and "b" in "aXb") in spoken input may support the acquisition of morpho-syntactic dependencies (e.g. "The princess 'is' kiss'ing' the frog"). Functional morphemes in morpho-syntactic dependencies are often marked by perceptual cues that render…

The relationship between language pedagogy and the content and language integrated learning (CLIL) classroom is a key issue for research into CLIL. In the Netherlands, as in other European contexts, non-native speakers of a target language with a non-language teaching background teach CLIL content lessons. Whilst CLIL teachers teaching their…
