It is a good practice to try to understand matters at hand by first stepping back and adopting an historical perspective, which I will begin this review by doing. Next, I will take up the challenges that each of the authors in the articles in this volume has presented for the study of complexity, accuracy, and fluency (CAF) in second language…

This article critically scrutinizes a number of issues involved in the definition and operationalization of complexity, accuracy, and fluency (CAF) constructs. It argues for maintaining clearer distinctions between CAF, on the one hand, and notions such as linguistic development and communicative adequacy, on the other. Adequacy, in particular,…

Two recent papers (de Villiers & Johnson, 2007; Johnson, de Villiers & Seymour, 2005) have claimed that children have difficulty with verbal "-s" until five- six-years-old. This contrasts with perceptual studies showing evidence for sensitivity to the grammatical properties of verbal "-s" as young as 1;4. These apparently conflicting findings can…

While agreeing with Lardiere that the "parameter-resetting" approach to understanding second language acquisition (SLA) needs rethinking, it is suggested that a more construction-based perspective runs the risk of losing deductive and explanatory power. An alternative is to investigate the constraints on feature assembly/re-assembly in second…

The clearest writing style is one in which the grammatical structures of a sentence most redundantly support the perceived semantic structure; a textured style is one in which the syntactic complexity invests a sentence with distinctive force. (DD)

Advanced learners of second languages and natural language processing systems both demand much more detailed lexical information than conventional dictionaries provide. Text composition, whether by humans or machines, requires a thorough understanding of relationships between words, such as selectional restrictions, case patterns, factives, and…
