In bilinguals and second language learners, the native (L1) and nonnative (L2) languages coexist and interact. The L1 influences L2 production via forward transfer, as is seen with foreign accents. However, language transfer is bidirectional: even brief experience with an L2 can affect L1 production, via backward transfer. Here, we review the…

The present meta-analysis examined the overall average correlation (weighted for sample size and corrected for measurement error) between passage-level second language (L2) reading comprehension and 10 key reading component variables investigated in the research domain. Four high-evidence correlates (with 18 or more accumulated effect sizes: L2…

This review article analyzes the results of several representative English morpheme-order studies conducted in the 1970s in light of current functional-category theory. Comparative analysis found significant discoveries related to category-specific development of functional projections in first language acquisition and cross-categorical…

Examines trends in second language (L2) communication strategy (CS) research. A comprehensive review is included of the relevant literature from the last two decades, with particular reference to the different ways in which CSs have been defined and to the corresponding influences on the organization of strategy taxonomies. (92 references)…

A review of research about second language learning indicates that nonprimary acquisition is sensitive to the center-periphery distinction. There is clear evidence that this construct has reflexes in interlanguage word order with respect to the probability of native word order influence, difficulty, and order of emergence. (CB)
