It has long been recognized that there is a natural dependence between theories of knowledge representation and theories of knowledge acquisition, with the idea that the right knowledge representation enables acquisition to happen as reliably as it does. Given this, a reasonable criterion for a theory of knowledge representation is that it be…

Purpose: This follow-up study examined whether a parent intervention that increased the diversity of lexical noun phrase subjects in parent input and accelerated children's sentence diversity (Hadley et al., 2017) had indirect benefits on tense/agreement (T/A) morphemes in parent input and children's spontaneous speech. Method: Differences in…

Purpose: This longitudinal study compared the development of hand and index-finger pointing in children with typical language development (TD) and children with language delay (LD). First, we examined whether the number and the form of pointing gestures during the second year of life are potential indicators of later LD. Second, we analyzed the…

Spontaneous motion is one of the most basic event types, but different languages use varying patterns to express it. For example, English usually encodes path information in prepositional phrases or adverbial particles, while Korean maps path information onto verbs (Talmy, 1985). This study predicts that this typological difference would affect…

The article discusses an experiment that researched the intentional vs incidental ESP vocabulary uptake in two university groups of third year political science students and addresses the implications of using an authentic audiovisual material as an input text for an ESP course. The procedure of intentional vocabulary learning involved…

A great deal of research undertaken in child language development, neurolinguistics and various branches of functional and cognitive linguistics has shown that a main source of language development is the spoken input to which learners are exposed. Despite the fact that for most adult L2 learners, the greatest exposure to the L2 is the input they…

Microgenetic design or microgenetic method is a scientific method in which the same setting is studied repeatedly in order to observe possible changes in details. Reviewing the current literature, one can conclude that microgenetic methods have positive effects of learning in general and language learning in particular. The main objective of the…

This study examined the quantity and quality of parental linguistic input to toddlers with moderate hearing loss (MHL) compared with toddlers with normal hearing (NH). The linguistic input to eighteen toddlers with MHL and twenty-four toddlers with NH was examined during a 10-minute free-play activity in their home environment. Results showed that…

The relationship between second language (L2) learners' orthographic vocabulary knowledge and extensive reading is quite well researched. However, the way phonological vocabulary knowledge and extensive listening/viewing interacts remains not so well investigated. The current study examines the effect of extensive viewing of English movies…

Student-centered instruction is a shared goal in English as a second or foreign language (ESL/EFL) settings that embrace communicative language teaching (CLT) principles (East 2015). Student-centered classrooms create opportunities for learners to have consistent and meaningful interactions--two-way exchanges of ideas--using their second language…

It is proposed that humans have available to them two systems for interpreting natural language. One system is familiar from formal semantics. It is a type based system that pairs a syntactic form with its interpretation using grammatical rules of composition. This system delivers both plausible and implausible meanings. The other proposed system…

This paper presents an argument for how second language acquisition (SLA) research should be carried out if a researcher is genuinely interested in learner grammar (i.e., knowledge of language), its acquisition and use. SLA research has expanded greatly over many years and currently spans many subfields, but researchers share one main goal: to…

Two eye-tracking experiments tested (a) whether L2 learners benefit from the consistency of input modality (auditory instead of written processing instruction [PI] training) and (b) whether they benefit from training using the same voice as the test voice. Results confirmed a robust effect of PI training on picture-selection accuracy, yet the…

We examined the role of modality in learning second language (L2) grammar and forming implicit (unconscious) and explicit (conscious) knowledge. To this end, we isolated the effects of the physical medium of input (i.e., aural or visual) from those of the presentation method (i.e., word-by-word or simultaneous). We also explored the role of test…

Instructional scaffolding--the use of resources, structures, and verbal interaction to help students do challenging academic work--is known to be essential for effective English language reading instruction for emergent bilinguals (EBs; Goldenberg, 2010; Walqui, 2006). Yet little systematic research examines the scaffolds that teachers use.…
