Housen, Alex, Ed.; Kuiken, Folkert, Ed.; Vedder, Ineke, Ed. – Language Learning & Language Teaching (MS), 2012
Research into complexity, accuracy and fluency (CAF) as basic dimensions of second language performance, proficiency and development has received increased attention in SLA. However, the larger picture in this field of research is often obscured by the breadth of scope, multiple objectives and lack of clarity as to how complexity, accuracy and…

Housen, Alex; Kuiken, Folkert; Vedder, Ineke – Language Learning & Language Teaching (MS), 2012
The theme of this volume, complexity, accuracy and fluency (CAF) as dimensions of second language production, proficiency and development, represents a thriving area of research that addresses two general questions that are at the heart of many studies in second language acquisition and applied linguistics: What makes a second language (L2)…

Bulte, Bram; Housen, Alex – Language Learning & Language Teaching (MS), 2012
This chapter takes a critical look at complexity in L2 research. We demonstrate several problems in the L2 literature in terms of how complexity has been defined and operationalised as a construct. In the first part of the chapter we try to unravel its highly complex, multidimensional nature by presenting a taxonomic model that identifies major…

Towell, Richard J. – Language Learning & Language Teaching (MS), 2012
The aim of this chapter, which is written from the perspective of psycholinguistic SLA research, is to establish a possible relationship between representations, processes and mechanisms of second language learning and knowledge as defined from within psycholinguistic SLA on the one hand, and the more behavioural performance outcomes such as…

Agren, Malin; Granfeldt, Jonas; Schlyter, Suzanne – Language Learning & Language Teaching (MS), 2012
This chapter addresses the question of the growth of accuracy and complexity in L2 French from the perspective of developmental sequences of morphosyntax, developmental stages and linguistic profiling. The six developmental stages for L2 French proposed by Bartning and Schlyter (2004) are presented and exemplified and new results are added to the…

De Jong, Nivja H.; Steinel, Margarita P.; Florijn, Arjen F.; Schoonen, Rob; Hulstijn, Jan H. – Language Learning & Language Teaching (MS), 2012
This study investigated how task complexity affected native and non-native speakers' speaking performance in terms of a measure of communicative success (functional adequacy), three types of fluency (breakdown fluency, speed fluency, and repair fluency), and lexical diversity. Participants (208 non-native and 59 native speakers of Dutch) carried…

Kuiken, Folkert; Vedder, Ineke – Language Learning & Language Teaching (MS), 2012
The research project reported in this chapter consists of three studies in which syntactic complexity, lexical variation and fluency appear as dependent variables. The independent variables are task complexity and proficiency level, as the three studies investigate the effect of task complexity on the written and oral performance of L2 learners of…

Skehan, Peter; Foster, Pauline – Language Learning & Language Teaching (MS), 2012
This chapter will present a research synthesis of a series of studies, termed here the Ealing research. The studies use the same general framework to conceptualise tasks and task performance, enabling easier comparability. The different studies, although each is self-contained, build into a wider picture of task performance. The major point of…

Gunnarsson, Cecilia – Language Learning & Language Teaching (MS), 2012
The present longitudinal case study investigated the development of fluency, complexity and accuracy--and the possible relationships between them--in the written production of L2 French. We assessed fluency and complexity in five intermediate learners by means of conventional indicators for written L2 (cf. Wolfe-Quintero et al. 1998), while…

Ferraris, Stefania – Language Learning & Language Teaching (MS), 2012
This chapter presents the results of a study on interlanguage variation. The production of four L2 learners of Italian, tested four times at yearly intervals while engaged in four oral tasks, is compared to that of two native speakers, and analysed with quantitative CAF measures. Thus, time, task type, nativeness, as well as group vs. individual…

Myles, Florence – Language Learning & Language Teaching (MS), 2012
The purpose of this chapter is to investigate how complexity, accuracy and fluency interact in early L2 development, when learners' linguistic means are underdeveloped. Learners then resort to rote-learned formulaic sequences to complement their current grammar when it is unable to meet their communicative needs. The interplay between their…

Levkina, Mayya; Gilabert, Roger – Language Learning & Language Teaching (MS), 2012
This paper examines the impact of task complexity on L2 production. The study increases task complexity by progressively removing pre-task planning time and increasing the number of elements. The combined effects of manipulating these two variables of task complexity simultaneously are also analyzed. Using a repeated measures design, 42…

Tonkyn, Alan Paul – Language Learning & Language Teaching (MS), 2012
This paper reports a case study of the nature and extent of progress in speaking skills made by a group of upper intermediate instructed learners, and also assessors' perceptions of that progress. Initial and final interview data were analysed using several measures of Grammatical and Lexical Complexity, Language Accuracy and Fluency. These…
