Vocabulary can be learned in a variety of ways. The most common of these is incidental learning through listening and reading using context clues to work out the meaning. Vocabulary knowledge can also be enriched through having to produce vocabulary (Joe, Nation, and Newton, 1996) in spoken or written form. The quality and thoughtfulness of the production influences the quality of storage of th...

This study investigated predictors of growth in toddlers' vocabulary production between the ages of 1 and 3 years by analyzing mother-child communication in 108 low-income families. Individual growth modeling was used to describe patterns of growth in children's observed vocabulary production and predictors of initial status and between-person change. Results indicate large variation in growth ...

This article reviews research related to conscious and unconscious processes in L2 and LI vocabulary acquisition. Firstly it presents a summary conceptual analysis of the different aspects of vocabulary acquisition. After demonstrating that most vocabulary acquisition typically comes as a result of incidental learning, it next considers three research areas: (i) the associations between vocabul...

Children with pre- or perinatal brain injury (PL) exhibit marked plasticity for language learning. Previous work has focused mostly on the emergence of earlier-developing skills, such as vocabulary and syntax. Here we ask whether this plasticity for earlier-developing aspects of language extends to more complex, later-developing language functions by examining the narrative production of childr...

The purpose of the present study was to identify any significant relationship between critical thinking ability, L2 vocabulary knowledge, and L2 vocabulary learning strategies of Iranian EFL learners. To this aim, the productive vocabulary levels test was administered to measure the learner’s L2 vocabulary knowledge and observe homogeneity in terms of vocabulary knowledge. At the second stage, ...

It is often assumed that young bilinguals are lexically delayed in comparison to monolinguals. A comprehensive comparison of comprehension and production vocabulary in 31 firstborn bilingual and 30 matched monolingual children fails to find empirical foundation for this assumption. Several raters completed Dutch and French adaptations of the MacArthur Communicative Development Inventories for c...

This experimental study investigated the comparative effects of non-negotiated pre-modified input, negotiation of input without output, and negotiation of input plus pushed output on EFL learners’ comprehension and production. Before starting the study, forty-three male and female adult students at intermediate level took the Preliminary English Test (PET) and 30 of the students who scored one ...
