Although many studies have suggested positive effects for speaking or output practice on L2 grammar development, the question of how speaking affects L2 grammar remains. This study specifically examines how output affects the explicit and implicit knowledge of Spanish indirect object pronouns (IOPs). It also investigates levels of L2 grammar…

A "cognitivist" approach to cognition has traditionally dominated second language acquisition (SLA) studies. In this article, I examine two alternative approaches--"extended cognition" and "embodied cognition"--for how they might help us conceptualize SLA. More specifically, I present: (i) summaries of extended and embodied cognition, followed by…

Dual-system models suggest that English past tense morphology involves two processing routes: rule application for regular verbs and memory retrieval for irregular verbs. In second language (L2) processing research, Ullman suggested that both verb types are retrieved from memory, but more recently Clahsen and Felser and Ullman argued that past…

The Aspect Hypothesis assumes that--in early interlanguages--the perfective past spreads from telic to atelic verbs because events occurring in the past are easier to be associated with predicates having an inherent endpoint in their lexico-conceptual representation. In this study it is questioned whether for initial L2ers knowing the general…

Research has described the key role of formulaic language use in both written and spoken communication (Schmitt, 2004; Wray, 2002), as well as in relation to L2 learning (Ellis, Simpson--Vlach, & Maynard, 2008). Relatively few studies have examined related fixed and semi-fixed multi-word units (MWUs), which comprise fixed parts with the potential…

This paper outlines a procedure for language textbook analysis from the perspective of second language acquisition (SLA) principles as a preliminary procedure to evaluation for selection. The aim is to provide a tool that allows comparison of the potential of textbooks for supporting students' language learning. To this end, ten general principles…

The study of language production by adults who are learning a second language (L2) has received a good deal of attention especially when it comes to omission of inflectional morphemes within L2 utterances. Several explanations have been proposed for these inflectional errors. One explanation is that the L2 learner simply does not have the L2…

Data-driven learning (DDL) is an inductive approach to language learning in which students study examples of authentic language and use them to find patterns of language use. This inductive approach to learning has the advantages of being learner-centered, encouraging hypothesis testing and learner autonomy, and helping develop learning skills.…

Some syllables are louder, longer and stronger than other syllables at the lexical level. These prominent prosodic characteristics of certain syllables are captured by suprasegmental features including fundamental frequency, duration and intensity. A language like English uses fundamental frequency, duration and intensity to distinguish stressed…

Within the growing body of work that is sometimes labeled CA-for-SLA, there is a need for more research with longitudinal data. Hellermann and Cole (2009) provide a valuable contribution in this area. However, in doing so, they also make use of an exogenous theory of learning, situated learning theory (Lave and Wenger 1991), and its associated…

Research has demonstrated that second language (L2) vocabulary learning improves when target words are presented in acoustically varied compared with acoustically consistent formats. The present study investigated the extent to which this benefit of acoustic variability is a consequence of difficult encoding demands (cognitive effort hypothesis)…

This article summarizes the individual contributions to this special issue and discusses the advantages and implications of adopting a multilingual approach. The advantages include the possibility of examining language practices in context and providing insights about the way languages are acquired and used. This multilingual approach also opens…

Investigators of first language attrition, early bilingualism and child second language learning have found common ground on a number of important points. The present review of the research will show that the study of unevenness in the early development of two languages reveals more clearly how the critical problems for future research on…

In 1997 I published a paper in Language Teaching entitled "Form-focused instruction and second language acquisition: A review of classroom and laboratory research". The paper reviewed the results of studies investigating the effects of form-focused instruction (FFI) on second language (L2) learning. It was organized around seven questions,…

We examined how age of acquisition in Spanish heritage speakers and L2 learners interacts with implicitness vs. explicitness of tasks in gender processing of canonical and non-canonical ending nouns. Twenty-three Spanish native speakers, 29 heritage speakers, and 33 proficiency-matched L2 learners completed three on-line spoken word recognition…
