This paper discusses the stage of second language acquisition known as attrition and what learners and teachers can do to prevent attrition and promote retention. Attrition is the stage at which a learner's attained proficiency declines due to a reduction of contact with the second language, whether from lack of contact with other speakers of the…

This study compares the effect of using corpus-based materials and activities for the instruction of pragmatic routines under two conditions: implementing direct corpus searches by learners during classroom instruction and working with teacher-developed corpus-based materials. The outcome is compared to a repeated-test control group. Pragmatic…

This study investigates the effects of instruction (input plus focused metapragmatic noticing) on the oral production of conventional expressions, particularly those conventional expressions which perform specific pragmatic functions in English. Using a pre-test-instruction-post-test design we tested 36 university-level students in six intact…

This study investigates the effect of instruction on the acquisition of pragmatic routines used in academic discussion, specifically expressions of agreement, disagreement, and clarification. Thirty-seven learners, including an experimental group of 26 students and a control group of 11 students, participated in the study. Five intact classes…

This article provides a comprehensive synthesis of research on language attrition to date, with a view to establishing a theoretically sound basis for future research in the domain of second language (L2) attrition. We identify the variables that must be tracked in populations who experience language loss, and we develop a general model for the…

The aspect hypothesis (Andersen & Shirai, 1994) proposes that language learners are initially influenced by the inherent semantic aspect in the acquisition of tense and aspect (TA) morphology. Perfective past emerges earlier with accomplishments and achievements and progressive with activities. Although this hypothesis has been extensively…

The study of language development in second language acquisition naturally leads to information about linguistic processes of second language acquisition, but it also sheds light on learners' individual differences. This article examines the acquisition of the future in L2 English and explores how learners in a longitudinal study respond to input,…

Considers the proposed developmental sequence of formula>low-scope>pattern>construction in the emergence of future expression in a longitudinal study of adult learners of English as a Second Language. Findings suggest that the use of formulaic expressions may be subject to individual variation and that learners may use formulaic…

Investigates the nature of input available to learners in the institutional setting of the academic advising session. Results indicate that evidence for the realization of speech acts, positive evidence from peers and status unequals, the effect of stereotypes, and limitations of a learner's pragmatic and grammatical competence are influential…

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)
