This chapter focuses on formulating North American English (NAE) phonological rules and discussing their pedagogical implications. It begins with a brief account of NAE phonology as a rule-governed system and then outlines feature-based phonology as a theoretical framework in which phonological rules operate. The chapter further defines an inventory of distinctive features for characterizing the NAE phonological system. After discussing rule components and matrix underspecification, the chapter presents phonological rules subsumed under seven categories: deletion, epenthesis, metathesis, reduction, assimilation, dissimilation, and morphophonology. Most rules are couched in three expressions—prose, semi-formal, formal—to meet different needs of readers. Pedagogical implications of phonological rules, discussed in the last section, are explicated in the framework of language transfer and universal grammar. The same section also emphasizes the importance of balancing linguistic analysis and classroom practice.

Current ambulatory technologies are highly relevant for neuropsychological assessment and treatment as they provide a gateway to real life data. Ambulatory assessment of cognitive complaints, skills and emotional states in natural contexts provides information that has a greater ecological validity than traditional assessment approaches. This issue presents an overview of current technological and methodological innovations, opportunities, problems and limitations of these methods designed for the context-sensitive measurement of cognitive, emotional and behavioral function. The usefulness of selected ambulatory approaches is demonstrated and their relevance for an ecologically valid neuropsychology is highlighted.
