Few adult second language (L2) learners successfully attain high-level proficiency. Although decades of research on beginning to intermediate stages of L2 learning have identified a number of predictors of the rate of acquisition, little research has examined factors relevant to predicting very high levels of L2 proficiency. The current study,…

This article presents a selective overview of studies that have investigated how advanced adult second language (L2) learners process morphologically complex words. The studies reported here have used different kinds of experimental tasks (including speeded grammaticality judgments, lexical decision, and priming) to examine three domains of…

The incidence of nativelikeness in adult second language acquisition is a controversial issue in SLA research. Although some researchers claim that any learner, regardless of age of acquisition, can attain nativelike levels of second language (L2) proficiency, others hold that attainment of nativelike proficiency is, in principle, impossible. The…

This study explored learning and generalization of parts of the Russian case-marking paradigm, an inflecting-fusional system in which affixes simultaneously mark several grammatical features (case, gender, number, animacy). In Experiment 1, adult English speakers (N = 43) were exposed to nouns with transparent gender marking in the nominative case…

McCormack and Hoerl's state of the art review of the development of temporal concepts from the end of infancy to the end of the fifth year shows that young children's conception of time is quite different from that of adults. Adults and 5-year-old children can construe an event from a range of temporal perspectives and can describe it from a…

Describes two experiments which assessed the ability of adult second language (L2) learners to produce and comprehend real, unreal, and past unreal English conditional sentences. Developmental differences are analyzed in relation to distinctive features. The analyses lend support to the explanatory power of markedness theory in explaining L2…
