Most second language acquisition (SLA) research has documented the processes involved in learning second/foreign languages, with few studies focusing on the durability of attained second language (L2) skills once instructed learners/users are no longer receiving formal instruction. The current study examines the effects of continued exposure and…

A large number of children are exposed to more than one language. One well-established method of assessing early vocabulary development in monolingual children is parent report; however, its use in bilingual/multilingual contexts is less established and brings unique challenges. In this methodological scoping review, we reviewed studies of early…

Chinese learners of English often experience difficulty with English tense presumably because their native language is tenseless. We showed that this difficulty relates to their incomplete conceptual representations for tense rather than their poor grammatical rule knowledge. Participants made acceptability judgments on sentences describing…

This study investigated how much practice is necessary for learners to attain durable second language (L2) grammar knowledge. Using digital flashcards, 119 participants practiced translating 12 sentences into an artificial language, followed by feedback, until they had typed all sentences correctly. Participants repeated this activity in one, two,…

In this study, we examined the effect of previewing unfamiliar vocabulary on the real-time reading behavior of first language (L1) and second language (L2) readers. University students with English as their L1 or L2 read passages with embedded pseudowords. In a within-participant manipulation, definitions of the pseudowords were either previewed…

This study examined the relationship of linguistic complexity, captured using a set of lexical richness, syntactic complexity, and discoursal complexity indices, to second language (L2) learners' perception of text difficulty, captured using L2 raters' comparative judgment on text comprehensibility and reading speed. Testing materials were 180…

The present study administered six test instruments to 13- to 14-year-old learners of English in Austria and Sweden (N = 213), countries offering settings with more explicit and implicit learning environments, respectively. Confirmatory Factor Analyses for Austria yielded a factor comprising timed grammaticality judgment tests, an oral narrative…

Some listeners exhibit higher sensitivity to subphonemic acoustic differences (i.e., higher speech gradiency). Here, we asked whether higher gradiency in a listener's first language (L1) facilitates foreign language learning and explored the possible sources of individual differences in L1 gradiency. To address these questions, we tested 164…
