The interactionist hypothesis holds that conversational interaction facilitates second language (L2) learning by providing learners opportunities to receive meaningful input, modify their output, and attend to language form. Although research has often explored the efficacy of different types of L2 instruction (deductive or inductive), few studies…

Although cross-linguistic research on second language tense-aspect acquisition has uncovered universal tendencies concerning the association between verbal semantics and tense-aspect markers, it is still unclear what mechanisms underlie this link. This study investigates the acquisition of two imperfective aspect markers ("-ko iss-" and…

The article summarizes results from two experimental studies on reactivity. In the first experiment, 24 college-age participants received a computerized treatment that delivered a grammar lesson, practice, and feedback on assignment of semantic functions in Latin. Verbalizations did not induce reactivity on accuracy, but they slowed down posttest…

Research on second language lexical development during reading has found positive effects for word frequency, the provision of glosses, and elaborative word processing. However, findings have been inconclusive regarding the effect of such intervention tasks on long-term retention. Likewise, few studies have looked at the cumulative effect of…

Deaf and hearing students' knowledge of English sentences containing universal quantifiers was compared through their performance on a 50-item, multiple-picture task that required students to decide whether each of five pictures represented a possible meaning of a target sentence. The task assessed fundamental knowledge of quantifier sentences,…

The study reported in this article describes second language (L2) vocabulary learning outcomes associated with adult L2 reading comprehension processes, thus connecting L2 learning with the complex cognitive and linguistic processing involved in reading. The study aimed to determine whether background knowledge moderated the relationship between…

Reviews research on the social interaction and negotiation of second language (L2) learners and their interlocutors. This research illustrates ways in which negotiation contributes to conditions, processes, and outcomes of L2 learning by facilitating learners' comprehension and structural segmentation of L2 input, access to lexical form and…

Two studies investigated the effects of modified interaction on comprehension and vocabulary acquisition among Japanese high school students learning English as a Second Language. The studies found that interactionally modified input resulted in better comprehension and the acquisition of more new words than premodified input. (MDM)

Examines the emergence of the present perfect in the interlanguage of instructed adult learners of English as a Second Language. Findings indicate that adding a new inflection in the tense/aspect system requires establishing new form-meaning associations as well as revising existing ones. (44 references) (Author/CK)
