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…

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…

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…
