This article provides a conceptual review of the principles of input spacing as they might relate specifically to oral task repetition research and presents some of the common methodological considerations from the broader input spacing literature. The specific considerations discussed include the interaction between intersession intervals and…

Spoken language outcomes after cochlear implantation are highly variable. Some variance can be attributed to individual characteristics. Research with typically hearing children suggests that the amount of language directed to children may also play a role. However, several moderating factors may complicate the association between language input…

Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. This is "syntactic bootstrapping." A learner that uses syntactic bootstrapping to foster lexical acquisition must first have identified the semantic information that a syntactic context provides. Based on the "semantic seed…

The paper discussed in detail the process of language development and the process of language acquisition in early childhood. It also gave a brief overview of the theoretical frame of reference of language development. The paper included an in depth explanation of the importance and impact of overexposure for early second language acquisition and…

Theoretical approaches within the cognitive-interactionist framework (Long, 2015) have identified various aspects of L2 input and characteristics of instruction that predict learners' L2 outcomes. Such strategies of L2 teaching relate to shaping characteristics of communicative activities in which the L2 is embedded and modifying L2 input, L2…

In this commentary, the author defends the Multiple Grammars (MG) theory proposed by Luiz Amaral and Tom Roepe (A&R) in the present issue. Topics discussed include second language acquisition, the concept of developmental optionality, and the idea that structural decisions involve the lexical dimension. The author states that A&R's…

In the early years of the "Journal of Child Language," there was considerable disagreement about the role of language input or adult-child interaction in children's language acquisition. The view that quantity and quality of input to language-learning children is relevant to their language development has now become widely accepted as a…

The articles in this special issue provide a complex picture of acquisition in bilinguals in which the factors that contribute to patterns of performance in bilingual children's two languages are myriad and diverse. The processes and contours of development in bilingual children are influenced, not only by the quantity, quality, and contexts…

Poverty of the stimulus (POS) arguments have instigated considerable debate in the recent linguistics literature. This article uses the comparative method to challenge the logic of POS arguments. Rather than question the premises of POS arguments, the article demonstrates how POS arguments for individual languages lead to a "reductio ad absurdum"…

With the ever increasing number of studies on formulaic language, we are beginning to learn more about the processing of formulaic language (e.g. Ellis et al. 2008; Siyanova et al. 2011), its use in speech (e.g. Aijmer 1996; Wood 2012) and writing (e.g. Hyland 2008a, 2008b) and its application in natural language processing (e.g. Tschichold 2000).…

There is considerable debate regarding the simplification of adults' language when talking to young children with expressive language delays (ELD). While simplified input, also called telegraphic speech, is used by many parents and clinicians working with young children, its use has been discouraged in much of the clinical literature. In addition…

Following from Lewis, Jones, and Baker (this issue), this article analyses the relationship between the new concept of "translanguaging" particularly in the classroom context and more historic terms such as code-switching and translation, indicating differences in (socio)linguistic and ideological understandings as well as in classroom…

The phonetic characteristics of canonical babbling produced by Korean- and English-learning infants were compared with consonant and vowel frequencies observed in infant-directed speech produced by Korean- and English-speaking mothers. For infant output, babbling samples from six Korean-learning infants were compared with an existing English…

This paper discusses different approaches to language acquisition in relation to children's acquisition of word order in "wh"-questions in English and Norwegian. While generative models assert that children set major word order parameters and thus acquire a rule of subject-auxiliary inversion or generalized verb second (V2) at an early stage, some…

This paper identifies a general limitation on printed text as a source of input for language acquisition. The paper contends that printed material can only serve as a source of linguistic input to the extent that the learner is able to make use of phonological information in reading. Focusing on evidence from the acquisition of spoken language and…
