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…

This study investigates whether there are different first-language-second-language (L1-L2) dependency resolutions by focusing on less-studied crosslinguistic variances in L2 acquisition of Chinese, a null-subject language, by speakers of English, a non-null-subject language. The overt subject pronoun of a Chinese main clause has free orientation…

How does linguistic structure affect children's developing cardinal number knowledge? The bootstrapping theory proposes that children might use syntactic information provided by known words such as quantifiers to bootstrap the meanings of unfamiliar words such as number words. Prior studies of numeral and quantifier development have indicated that…

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…

Learners of a nonnull subject language (e.g., English) whose first language (L1) is a null subject language (e.g., Spanish) can show some optionality in the interpretation of overt subject pronouns in the second language (L2). By exposing L2 learners to nativelike interpretations of pronouns in discourse, we aim at understanding how exposure can…

This study sets out to investigate possible effects of previously learned languages on the acquisition of English as a third language by examining six prepositions (in, on, at, behind, over, to) when they denote spatial relations. Two picture description tasks were employed to find out which of the two known languages (L1 and/or L2) is the major…

Many studies have explored the second language (L2) acquisition of relative clauses (RCs) and whether L2 speakers transfer a resumptive strategy from first language (L1) to L2. While evidence seems to suggest that there are significant L1-L2 differences in the processing of RCs, relatively little is known about the source of non-target-like L2…

This study investigates the acquisition of null subjects by Mandarin Chinese native speakers ('Chinese NSs' hereafter), with different levels of L2 English proficiency, at initial stages of L3 Italian acquisition. The aim is to find out if, when acquiring Italian null subjects, Chinese NSs resort to their L1, which, like the L3, allows null…

The early use of first and second person pronouns has been viewed as a sign of emerging social understanding. However, it may also depend on general language development: pronouns do not appear among the first words children acquire. In addition, some languages conjugate verbs for person, and the inflections may thus show similar relations to…

Traditionally, transfer is described as interference and consequently as an unintentional mechanism. More recently, however, the perception of control in transfer has changed and it is now commonly accepted that transfer can occur both automatically and strategically. Studies have previously employed think-aloud protocols during writing tasks to…

By replicating Cho (2017), this article investigates how second language (L2) learners with an article-less first language acquire two types of English definiteness, anaphoric and nonanaphoric. Mandarin Chinese, as an article-less language, has a demonstrative determiner that shares the same feature set as the English definite article…

This study uses both offline and online tasks in order to investigate whether second language learners of English from an article-less first-language (Mandarin) are able to integrate the indefinite article into their grammar despite the lack of articles in their first language. This article reports on two studies, one on learners' sensitivity to…

This paper compares the initial state of second language (L2) and third language (L3) acquisition for English articles to examine the influence of L2 proficiency on positive transfer from L2 to L3. We tested 36 L1 Turkish/L2 German adolescent learners of L3 English (L3 group), 41 L1 Turkish adolescent learners of L2 English (L2 group), and 10…

This study explores the source of transfer in third language (L3) English by two distinct groups of Catalan-Spanish bilinguals, simultaneous bilinguals and late bilinguals. Our study addresses two research questions: (1) Does transfer come from the first language (L1), the second language (L2), or both? and (2) Does age of acquisition of the L2…

This article explores what kind of second language (L2) input influences Japanese learners' acquisition of adjective ordering restrictions (AOR) in English where Japanese exhibits no AOR. In Study I, an explicit instruction (EI) group (n = 13) and a natural exposure (NE) group (n = 12) responded to a preference task. In Study II, an input flood…
