Hu and Nation's (2000) study, which stipulated that second language (L2) readers need to be familiar with 98% of lexical items for adequate text comprehension, has become highly influential in L2 vocabulary research and pedagogy. However, the 98% critical threshold figure is based on findings from a research project in which a regression analysis…

This study investigated how adult second language (L2) learners of Mandarin Chinese use knowledge of phonological and lexical statistical regularities when acoustic information is insufficient for word recognition. A gating task was used to test intermediate L2 learners at two time points across a semester of classroom learning. Native Mandarin…

This study explored the impact of metacognitive instruction provided in conjunction with corrective feedback, investigating the moderating effects of two types of implicit corrective feedback (input-providing conversational recasts vs. output-prompting clarification requests) that targeted English third-person singular "-s" and…

This article calls attention to a facet of the expertise of second language (L2) learners of Japanese at the intersection of language, memory, gesture, and the psycholinguistics of a logographic writing system. Previous research has shown that adult L2 learners of Japanese living in Japan (similarly to native speakers of Japanese) often…

The present study implemented a sign-repetition task at two points in time to hearing adult learners of British Sign Language and explored how each phonological parameter, sign complexity, and iconicity affected sign production over an 11-week (22-hour) instructional period. The results show that training improves articulation accuracy and that…

In early stages of classroom language learning, many adult second language (L2) learners communicate primarily with one another, yet we know little about which speech stream characteristics learners tune into or the extent to which they understand this lingua franca communication. In the current study, 25 native English speakers learning German as…

Drawing on a large corpus of video-recorded classroom data, the goal of this study was to understand the processes and mechanisms associated with learning in individuals who have had little education in their home countries. In order to accomplish this goal, we measured the socio-interactive behaviors and the expression of personality behaviors in…

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…

Investigates adult second language learners' processing of English syntactically ambiguous sentences in which a prepositional phrase is interpreted as either a noun phrase or verb phrase attachment. Results reveal lexical, syntactic, prosodic, and contextual constraints on processing ambiguous sentences. (87 references) (Author/CK)

Explored the relationship of similarity, dissimilarity, and markedness to second language, specifically English, phonological acquisition. The article hypothesized that the rate of acquisition for a dissimilar phenomenon is faster than for a similar phenomenon. Findings revealed that degree of markedness can increase or decrease rate. (38…

Integrates the phonological research concerns of two language-learning populations: (1) adults acquiring a second language, and (2) children learning to correct functional speech sound errors. The basic theoretical and pedagogical aims overlapped for the two populations, and the results of research on either population had strong potential for…

Three oral testing methods (imitation, completion, and interview) were compared for reliability and validity with 143 adult Egyptian learners of English. Five components (raw score, fluency, pronunciation, grammar, and combined fluency-pronunciation-grammar) were analyzed for each method. Imitation showed the highest validity, with interview and…

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)

Studies on second-language acquisition of reflexives have experienced difficulties assessing learners' knowledge of the binding principles because of problems associated with ambiguous sentences where there is more than one antecedent for a reflexive. In this study, English-as-a-Second-Language students were tested using a variety of sentence…

Examines differences in oral narrative discourse of adult second-language learners of English on narrative tasks simulating the ability to describe events in the Here-and-Now versus the There-and-Then. Results indicate that complex tasks elicit less fluent, but more accurate and complex narration than do simpler tasks. (90 references) (Author/CK)
