The development of effective second and foreign (L2) language learning materials needs to be grounded in two types of theories: (a) a theory of language and language use and (b) a theory of language learning. Both are equally important, insofar as an effective learning environment requires an understanding of the knowledge, skills, and abilities that are being targeted as well as an idea of how learner development progresses. Although the author and colleagues have previously provided a theoretical basis for the construct of L2 pragmatic ability, and thus a theory of language use, the current paper focuses on learner development, particularly on the theoretical orientation towards L2 pragmatic learning. Given this superordinate goal, the paper will briefly review different theoretical paradigms that have been employed in adult L2 pragmatics development research. In the first part of the paper, I will provide an overview of the cognitive, socially oriented, and emergentist perspectives used in research on L2 pragmatic development. Then, based on the different ontological perspectives, I will discuss the affordances and challenges of applying a theoretical perspective to designing L2 pragmatic learning environments, drawing upon the example of the cognitively oriented information processing theory.
