Researchers in second language (L2) and education domain use different statistical methods to assess their constructs of interest. Many L2 constructs emerge from elements/parts, i.e., the elements "define" and "form" the construct and not the other way around. These constructs are referred to as emergent variables (also called…

This article provides a comprehensive synthesis of research on language attrition to date, with a view to establishing a theoretically sound basis for future research in the domain of second language (L2) attrition. We identify the variables that must be tracked in populations who experience language loss, and we develop a general model for the…

Evaluates two studies concerning the ease of learning Esperanto and concludes that the studies support Esperantists' claims that the language is easier to learn than are natural languages. The claim, however, could be challenged because of the wide range of variable factors involved in language learning. (Author/CB)

Selected language acquisition research findings are examined in the light of the language teacher's daily needs. Research results are reported that provide an empirical basis for selecting and grading materials, determining skills to be taught and their order of presentation, deciding on classroom presentation and procedures, and formulating…

We used event-related brain potentials (ERPs) to investigate the contributions of explicit and implicit processes during second language (L2) sentence comprehension. We used a L2 grammaticality judgment task (GJT) to test 20 native English speakers enrolled in the first four semesters of Spanish while recording both accuracy and ERP data. Because…

Investigates the interaction between the presence or absence of explicit instruction and the variables complexity and morphology/syntax in the acquisition of four second language (L2) structures. Results from computer-controlled posttests confirm the hypothesis that explicit instruction facilitates the acquisition of L2 grammar. (66 references)…

This article reviews previous studies of the effects of implicit and explicit corrective feedback on SLA, pointing out a number of methodological problems. It then reports on a new study of the effects of these two types of corrective feedback on the acquisition of past tense -ed. In an experimental design (two experimental groups and a control…
