Recently there has been some debate about the appropriacy of different lexical units in pedagogy and research (e.g., Brown et al., 2020; Dang & Webb, 2016a; Kremmel, 2016; Laufer & Cobb, 2020; McLean, 2018; Nation, 2016; Nation & Webb, 2011; Vilkaite-Lozdiene & Schmitt, 2020). The lexical unit (word types, lemmas, flemmas, word…

This paper reports on the reanalysis of Suzuki's (2017) experiment and investigated the extent to which learning schedules influence automatization of second language (L2) morphology. Sixty participants were separated into two groups, which studied morphological rules for oral production under short-spacing (3.3-day intervals) and long-spacing…

The current study examined the occurrence and benefits of linguistic alignment in two modalities, face-to-face (FTF) and synchronous computer-mediated communication (SCMC), focusing on stranded prepositions in relative clauses. It further examined how learner characteristics (i.e., working memory, language proficiency, previous knowledge of the…

Numerous studies have demonstrated that native Mandarin speakers have pervasive difficulties processing L2 English agreement morphology. However, less is known about the lexical and morphological cues that may modulate Mandarin speakers' sensitivity to English number agreement. To investigate this, we examined subject-verb agreement processing in…

In this article, we challenge the notion that aptitude--operationalized as grammatical sensitivity as measured by the Words in Sentences section of the Modern Language Aptitude Test--is central to adult second language (L2) acquisition. We present the findings of a study on the acquisition of two properties of Japanese, head-final word order and…

Sixty English as a foreign language learners were divided into high-, intermediate-, and low-level groups based on their scores on pretests of target vocabulary and Vocabulary Levels Test scores. The participants read 10 Level 1 and 10 Level 2 graded readers over 37 weeks during two terms. Two sets of 100 target words were chosen from each set of…

A large body of research has shown that suffixes--both inflectional and derivational--can be primed with adult native speakers, which informs our understanding of storage and access to morphology in mature systems. However, this line of research has not yet been conducted from an acquisition perspective: Little is known about whether or not…

Although claims about explicit and implicit language knowledge are central to many debates in SLA, little research has been dedicated to measuring the two knowledge types (R. Ellis, 2004, 2005). The purpose of this study was to validate the use of the battery of tests reported in Ellis (2005) to measure implicit and explicit language knowledge.…

The present study aims to sensitize SLA researchers to the importance of documenting and controlling for their participants' proficiency in the target language, with the goal of establishing more robust proficiency assessment standards in experimental research. First, this article presents a survey of recent (2000-2008) foreign and second-language…

Investigated the psychological factors that affect access to metalinguistic knowledge in second language (L2) production. A verbalization task was used to assess the metalinguistic knowledge about target uses and a judgment test was administered to determine relative prototypicality of these uses of 64 adult Chinese learners of English.…

Although Keenan and Comrie's (1977) noun phrase accessibility hierarchy (NPAH) has been shown to predict the difficulty order of relative clauses (RCs) in SLA, most studies of the NPAH have been on European languages. This paper tests the prediction for Japanese. Study 1 analyzes RCs in an oral interview corpus from 90 learners of Japanese at four…

The generalizability of previous research claims about the development of automaticity in the adult learning of alphabet arithmetic programs to the context of adult second-language acquisition are examined. Tests with second-language learners of English suggest a transition from algorithm-based processing to memory-based processing. Sample tests…

Variability has been the subject of recent debate in the study of learner interlanguage. Empirical evidence from a longitudinal study suggests that learning follows a systematic route. A grammaticality judgment test is appended. (Contains 19 references.) (Author/LB)

Evaluates two studies concerning the ease of learning Esperanto and concludes that the studies support Esperantists' claims that the language is easier to learn than are natural languages. The claim, however, could be challenged because of the wide range of variable factors involved in language learning. (Author/CB)

This article discusses how research on language transfer in the field of SLA can help to explain the origins of substrate influence in creoles and provide answers to more difficult questions concerning the distribution and verification of substrate features. First, it argues against the view that both SLA and transfer are not involved in the…
