Existing work on the acquisition of polarity-sensitive expressions (PSIs) suggests that children show an early sensitivity to the restricted distribution of negative polarity items (NPIs), but may be delayed in the acquisition of positive polarity items (PPIs). However, past studies primarily targeted PSIs that are highly frequent in children's…

According to rational adaptation approaches of language processing, readers adjust their expectations of upcoming information depending on the distributional properties of the preceding language input. However, adaptation to sentence structures has not been systematically attested, especially not in second-language (L2) processing. To further our…

Prediction in language comprehension has become a key mechanism in recent psycholinguistic theory, with evidence from lexical prediction as a primary source. Less work has focused on whether comprehenders also make structural predictions above the lexical level. Previous research shows that processing is facilitated for syntactic structures which…

While it is known that heritage speakers diverge from the homeland baseline, there is still no consensus on the mechanisms triggering this divergence. We investigate the impact of two potential factors shaping adult heritage language (HL) grammars: (1) cross-linguistic influence (CLI), originally proposed for second language acquisition (SLA), and…

A previous study has shown that children use recent input to adapt their syntactic predictions and use these adapted predictions to infer the meaning of novel words. In the current study, we investigated whether children could use this mechanism to disambiguate words whose interpretation as a noun or a verb is ambiguous. We tested 2- to 4-year-old…

This study investigates the effects of early second-language (L2) acquisition on introduction of characters in narrative discourse by comparing 5- and 7-year-old monolingual (first-language [L1] = Turkish) and bilingual (L1 = Turkish, L2 = English) children. Turkish does not have a grammaticalized article system like English which enables to…

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 study compared the effectiveness of negative evidence and enriched input on learning the verb-noun collocations. There were 52 English as Foreign Language (EFL) learners in this research study and they were randomly assigned to the negative evidence or enriched input groups. While the negative evidence group (n = 27) was provided with…

Number lends itself to the study of how input interacts with transferred first language (L1) knowledge to facilitate or impede second language (L2) learning. We present data from adult English speakers exposed for the first time to Indonesian, a language that expresses number through bare noun phrases, reduplication and numeral + classifier…

We examined how age of acquisition in Spanish heritage speakers and L2 learners interacts with implicitness vs. explicitness of tasks in gender processing of canonical and non-canonical ending nouns. Twenty-three Spanish native speakers, 29 heritage speakers, and 33 proficiency-matched L2 learners completed three on-line spoken word recognition…

The present article examines the effect of variable input on the acquisition of plural morphology in two varieties of Spanish: Chilean Spanish, where the plural marker is sometimes omitted due to a phonological process of syllable final /s/ lenition, and Mexican Spanish (of Mexico City), with no such lenition process. The goal of the study is to…

English sentences containing the universal quantifiers "each", "every", and "all" are highly complex structures in view of the subtleties of their scope properties and resulting ambiguities. This study explored the acquisition of universal quantifier sentences as reflected in the performance of three diverse college-level student groups on a…

Research has shown that the comprehension of definite referring expressions (e.g., "the triangle") tends to be faster for "given" (previously mentioned) referents, compared with new referents. This has been attributed to the presence of given information in the consciousness of discourse participants (e.g., Chafe, 1994) suggesting that given is…

Although it is widely acknowledged that collocations play an important part in second language learning, especially at intermediate-advanced levels, learners' difficulties with collocations have not been investigated in much detail so far. The present study examines ESL learners' use of verb-noun collocations, such as "take notes," "place an…

This study provides an account of the distributional information and the production rates in a particularly rich corpus of German child and adult language. Three structural domains are analysed: the parts-of-speech distribution for a coded corpus of circa one million words as well as the internal constituency of 300,000 noun phrases and almost…
