Twenty years ago, a state-of-the-art review in "SSLA" marked the coming of age of the study of temporality in second language acquisition. This was followed by three monographs on tense and aspect the next year. This article presents a state-of-the-scholarship review of the last 20 years of research addressing the aspect hypothesis (AH)…

This study explores how Korean-to-English machine translation (MT) systems (e.g., Google Translator, NAVER Papago) deal with Korean passive structures. Cross-linguistically, Korean and English passives show different ways to construct passive-voice sentences from active structure. English passives including with [to be + past participle] may have…

This study examines types and characteristics of data collection tasks used in studies on scope ambiguity in English involving a universally quantified noun phrase and negation, and investigates any differences in comprehension patterns across studies using different tasks. Since Musolino's seminal 1998 study using a truth value judgment task,…

At present, genre analysis of various types of texts has gained much attention by the researchers worldwide. The focus of genre analysis in this study is on the examination of thesis abstracts written by Pakistani students in the field of TEFL in connection with move structure, lexico-grammatical features and style of the writer. The corpus of…

The aim of this study is to investigate the relationship between frequency and language acquisition from many perspectives including implicit and explicit instruction, frequency effects on morpheme acquisition in L2, the relationship between frequency and multi-word constructions, frequency effects on phonetics, vocabulary, gerund and infinitive…

Early research on the Aspect Hypothesis yielded a rigid developmental sequence for the acquisition of grammatical aspect, in which developing L2 learners applied morphemes to mark aspect in accordance with the inherent lexical aspect of verbal prototypes. While studies from a variety of L2 backgrounds have amassed evidence for this hypothesis,…

This essay contributes to the research on the emergence of tense/aspect morphology by reviewing the results and task conditions of studies supporting either the Aspect Hypothesis (AH) or the Default Past Tense Hypothesis (DPTH) for second language (L2) learners of Spanish. The AH has found that past marking emerges based on inherent aspectual…

The paper reviewed studies in word-level processing skills and related areas, and profiled how the development of L2 word recognition and integration skills would contribute to autonomous "kango" (Chinese originated words or words created from Chinese originated words) vocabulary learning. Despite the fact that the acquisition of a…

Introduces the articles in this issue of "Language Sciences," which are dedicated to taking stock of both grammaticalization and so-called "grammaticalization theory." This introduction sets the stage for other papers by surveying the large range of definitions of grammaticalization in the literature and placing them in…

Examines Krashen's (1977) theory that postulates a distinction between language acquisition and language learning, reviewing recent studies on morpheme order, code-focused instruction, and grammatical rules that support the theory. Contrary to what has been claimed, the theory is not insulated against attempts to disconfirm it. (87 references)…

Details six major research findings regarding second-language acquisition, including transitional stages for acquiring syntax; fixed-order emergence of grammatical morphemes; language acquisition progress from unmarked to marked elements; first-language influence; rule-governed learner output; and learner access to input. (27 references) (CB)

This review article analyzes the results of several representative English morpheme-order studies conducted in the 1970s in light of current functional-category theory. Comparative analysis found significant discoveries related to category-specific development of functional projections in first language acquisition and cross-categorical…

Examines the way in which the reading aloud done by a second language learner of English can reveal aspects of the learner's interlanguage. Particular attention is paid to the learner's acquisition of the "-ed" past tense morpheme, and to the acquisition of pronouns. (Author/VWL)

Examines certain instructional effects on second-language acquisition, such as code-focused instruction and classroom interaction. Empirical research on instructional effects are outlined in relation to some basic issues, including learning environment influences and processing constraints. (54 references) (GLR)

An historical overview of research on second language acquisition considers research topics examined in observational/longitudinal studies and experimental studies. The questions that have reappeared across both observational and experimental studies concern: (1) whether second language learning is the same or different from first language…
