The ''ba, ba, ba'' sound universal to babies' babbling around 7 months captures scientific attention because it provides insights into the mechanisms underlying language acquisition and vestiges of its evolutionary origins. Yet the prevailing mystery is what is the biological basis of babbling, with one hypothesis being that it is a non-linguistic…

This paper reports an experimental investigation of the relative effects of processing instruction, structured input activities and explicit information on the acquisition of gender agreement in Italian adjectives. Subjects were divided into three groups: the first received processing instruction; the second group structured input only; the third…

Recent studies have suggested that cultures vary in subtle ways in the talk about talk that children hear and learn to produce. Twenty-two three-year-old children and their families in respectively Oslo, Norway and Cambridge, Massachusetts were observed during mealtime with the aim of identifying talk-focused talk. The analysis distinguished talk…

We present a hypothesis for a specific kind of code-mixing in young bilingual children, during the development of their two first languages, one of which is considerably weaker than the other. Our hypothesis, which we label the Ivy Hypothesis, is that, in the interaction meant to be in the weaker language, the child uses portions of higher…

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…

One of the great puzzles of language acquisition has been described as poverty of the stimulus: how are complex aspects of language acquired when they appear to be rare or even non-occurring in the input that a learner receives and comprehends? This article presents an emergentist solution to one aspect of this puzzle (involving relative clauses)…

This study investigates the effects of meaningful input- and output-based practice on SLA. First-semester Spanish students (n = 45) were assigned to processing instruction, meaningful output-based instruction, or control groups. Experimental groups received the same input in instruction but received meaningful practice that was input or output…

A lack of reading quantity in EFL (English as a Foreign Language) classrooms has remained one of the most serious problems faced by teachers of English in Japan. Although the extensive reading (ER) approach is regarded as having significant potential in addressing this problem, it is not used in many EFL classrooms. This study investigates the…

This study explored the effect on vocabulary retention of vocalizations involving three cognitive processing depths ("repetition," "manipulation," and "generation"). Eight participants in an English for academic purposes (EAP) context encountered five unknown words when working alone and five different words when working in pairs. In each…

Attempts to determine whether or not explicit information given to second-language learners receiving processing instruction is responsible for the beneficial effects of instruction. Results indicate that these beneficial effects derived from the structured input activities and not from the explicit explanation provided to learners. (22…

Tested preschool monolingual speakers of Spanish and English in their native countries on classification of familiar objects through a task assessing strategies in a free sort, a sort with instructions to use natural gender, and one for the Spanish speakers with instructions to use grammatical gender. Results suggest that instructional context and…

Examined the strength of the association between language exposure estimates and vocabulary learning for simultaneous bilingual infants with differing patterns of exposure to the languages being learned. Findings revealed that the correlation was strong, even for children whose language environments changed by more than 20% between observations.…

Naturalistic mother-child speech between autistic, Down's syndrome, or normal children and their mothers was studied to determine whether imitation facilitates grammar acquisition. Spontaneous utterances were longer and contained more advanced grammar than imitation utterances, indicating that imitation does not play a significant role in grammar…

Attempts to clarify the role of grammar in second-language instruction. It is suggested that changes in language teaching have encouraged the view that grammar is one of several dimensions along which learners need to progress to achieve greater proficiency but that it should not be dominant.

Topics for conversation courses include conversational rules and structure, conversational strategies, functions and meaning in conversation, and social and cultural contexts. The direct teaching of conversational skills involves adding specific language input, increasing the role of consciousness raising, and sequencing communicative tasks…
