In this article I make the point that there has been a continuous focus on second language development in second language acquisition research for over 40 years and that there is clear empirical evidence for generalizable developmental patterns. I will both summarize some of the core assumptions of Processability Theory (PT) as an approach to…

Ute Bohnacker's (2006) article on the acquisition of the verb second (V2) property in German by native speakers of Swedish (also a V2 language) is an attempted rebuttal of Hakansson et al.'s (2002) work on first language (L1) transfer and aspects of the underlying theory on which the work is based: Processability Theory (Pienemann, 1998). The…

Hudson addressed two issues on second-language acquisition: the validity of the multidimensional model and the application of developmental sequence findings to assessment and pedagogy. This response suggests that his lines of argument are based on serious conceptual flaws. (Contains 37 references.) (LB)

Crosslinguistic influence in second language acquisition is examined from a processing perspective. Applying Processibility Theory as the theoretical framework, claims that second language (L2) learners can only produce forms they are able to process. (Author/VWL)

Argues that the teachability of language is constrained by what the learner is ready to acquire. The Teachability Hypothesis, based on this constraint, uses a speech processing approach to explain second language acquisition and contains important psycholinguistic information on which second language teaching methods could be based.

Replies to Mellow's (1996) criticism of the authors' second language acquisition model. The article argues that this model is based on the psychological concept of exchange of linguistic information and that Mellow's evaluation of various types of transformational analysis is irrelevant. The article also addresses several points of detail in…
