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…

Children are adept at learning their language's speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, 2-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned…

This study analyses variation sets in a sample of child-directed speech (CDS) in Turkish in terms of their structure and effect on child speech. The term "variation set" was first introduced to describe the sequences of repetitions, in which the intention behind expressions stays the same throughout the whole conversation while the form…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

The main purpose of this study is to explore and examine an early bilingual child whose use of English might be different on the account of the context the child uses English. Specifically, it was sought to find out if the child resorted to different phonological varieties as well as different interaction patterns while communicating. The relevant…

The time frame for infants' acquisition of language constancy was probed, using the phonetic variation in a rarely heard accent (South African English) or a frequently heard accent (American English). A total of 156 Australian infants were tested. Six-month-olds looked longer to Australian English than less commonly heard South African accent, but…

The study examined the acquisition of two morphological procedures of noun pluralization in Palestinian Arabic: "Sound Feminine Plural" (SFP) and "Broken Plural" (BP). We tested if noun pluralization was affected by (1) the type of morphological procedure, (2) the degree of familiarity with the singular noun stem, and (3) the…

This study tested the effect of the phoneme's linguistic affiliation (Standard Arabic versus Spoken Arabic) on phoneme recognition among five-year-old Arabic native speaking kindergarteners (N=60). Using a picture selection task of words beginning with the same phoneme, and through careful manipulation of the phonological properties of target…

Adult second-language (L2) learners' perception of L2 phonetic segments is influenced by first-language phonological and phonetic properties. It was recently proposed that L2 vocabulary size in adult learners is related to changes in L2 perception (perceptual assimilation model), analogous to the emergence of first-language phonological function…

This is an expanded version of a paper given at a conference held in Cape Town, South Africa from December 11-13, 2008 entitled "The Native Speaker and the Mother Tongue." In keeping with the conference's themes of exploring and interrogating the notions of "mother tongue" and "native speaker," I consider…

A study of the acquisition of interrogative forms in children of high socioeconomic status reveals that utterances belong more to the colloquial than to the standard range. It is concluded that disadvantaged children would show similar usage, leading to the suggestion that teachers teach language as they use it. (Text is in French.) (CDSH/CLK)

According to the theory of Universal Grammar, the primary linguistic data guides children through an innately specified space of hypotheses. On this view, similarities between child-English and adult-German are as unsurprising as similarities between cousins who have never met. By contrast, experience-based approaches to language acquisition…

In this paper, the patterns of variability in the use of auxiliary verbs in English as a second language from speakers with a Persian ethnic background are compared to those of Persian, and English. The findings of the comparisons between L1, L2, and English help us determine how variable L2 is and what the sources of this variation are. Our…

The study of language acquisition requires that the analyst identify the learner's target and have available a grammatical description of the target. In the case of the Caribbean Creole environment, special caution is required in identifying the learner's target because substantial variation is intrinsic to the input and ambient language. Existing…

This study is a partial replication of a set of studies conducted to investigate the effects of unequal status on speech variation. It was found that, in some respects, first- and second-language variation may be quantitatively different. (52 references) (JL)
