This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

Language proficiency is multi-componential in nature and, according to many SLA researchers and L2 practitioners, is best captured by the concepts of complexity, accuracy, and fluency (CAF). Two of the three studies reported in this paper adopted the Cognition Hypothesis (Robinson, 2003) as the means to address the question of whether increasing…

This article evaluates the extent to which syntactic, lexical, and conversational factors can significantly predict the frequency and loci of stuttered moments in children's speech. A synthesis of the experimental and clinical evidence suggests ways in which the assessment and remediation of fluency disorders in children can be tailored to…
