To become a native speaker, beyond obligatory rules, children need to learn systematic variation in the language, as it is present at all levels of language structure and is an integral part of linguistic knowledge. To give an example in English, speakers sometimes pronounce words ending in -ing with -in' (e.g., working vs. workin') depending on…

This work investigates the acquisition of Spanish dative alternation (DA) in the production of English-Spanish bilingual and Spanish monolingual children. We explore whether "a/para"-datives and dative clitic doubled (DCLD) structures are syntactically derived from one another or, whether they are different structures. We also examine…

Children are known to be fast learners due to their neural plasticity. Learning a non-native language (L2) requires the mastering of new production patterns. In classroom settings, learners are not only exposed to the acoustic input, but also to the unfamiliar grapheme-phoneme correspondences of the L2 orthography. We tested how 9-10-year-old…

This article reports on how, against a background of relatively stable patterns of second language negation, a Japanese-speaking adult learning English made use of a negative formula, "I don't know," and how, in and through interaction, analyzed it into its component parts and began using "don't" more productively.…

This article analyses the styles of English produced by an adult migrant who started to speak the language later in life, and it approaches them from the perspective of quantitative style-shifting and discursive stylization. After defining style and the procedures needed to justify the term "L2," the study describes the focal informant's…

In this study we examined the effect of language experience on the production of second language (L2) allophones. We analysed production data of the Spanish stop-approximant alternation (b d g [similar to] [beta] [delta] [gamma]) from Low Intermediate and High Intermediate level native English/Spanish L2 speakers and five native Mexican Spanish…

What are the effects of experience on subsequent learning? We explored the effects of language-specific word order knowledge on the acquisition of sequential conditional information. Korean and English adults were engaged in a sequence learning task involving three different sets of stimuli: auditory linguistic (nonsense syllables), visual…

We report the results of two studies that investigate the factors contributing to non-native-like ability in child and adult heritage speakers by focusing on oral production of Differential Object Marking (DOM), the overt morphological marking of animate direct objects in Spanish. In study 1, 39 school-age bilingual children (ages 6-17) from the…

Learners frequently experience phonologically inconsistent input, such as exposure to multiple accents. Yet, little is known about the consequences of phonological inconsistency for language learning. The current study examines vocabulary acquisition with different degrees of phonological inconsistency, ranging from no inconsistency (e.g., both…

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…

This study examines an interlanguage in which Moroccan learners of Dutch use non-thematic verbs in combination with thematic verbs that can be inflected as well. These non-thematic verbs are real dummy auxiliaries because they are deprived of semantic content and primarily have a syntactic function. Whereas in earlier second language (L2) research…

This article deals with the interlanguage of adult second language (L2) learners acquiring finiteness. Due to the inaccessibility of bound inflectional morphology, learners use free morphology to mark a syntactic relationship as well as person and number features separately from the thematic verb, expressed by a pattern like "the man is go".…

Three issues of concern in language acquisition are discussed: (1) apparent attrition of the Language Acquisition Device (LAD) by puberty; (2) observable differences among second-language learners with respect to LAD efficiency; and (3) whether explicit rules of grammar can become part of linguistic competence.

A study compared the Swedish tone accent acquisition of native-speaking children (N=2) and nonnative speaking college students (N=12). Both groups overgeneralized one pitch pattern to all bisyllabic words. Children used "Accent 2" (two-peaked) and adults "Accent 1" (one-peaked), analogous to the prevailing patterns of their…

Misinterpretations of the logical subject of infinitives by second language learners and prelingually deaf adults are compared with children's extension of the minimal distance principle during acquisition of infinitive complement structures and other research studies. Later acquisition of certain structure is explained in terms of the sentences'…
