An intraverbal assessment was administered to older adults with aphasia, using a hierarchy of questions that required increasingly complex verbal discriminative stimulus control. Five categories of errors were defined and analyzed for putative stimulus control, with the aim to identify requisite assessment components leading to more efficient and…

A theory of sentence production is presented that accounts for facts about speech errors, including (1) the kinds of errors that occur; (2) the constraints on their form; and (3) the conditions that precipitate them. Two simulation models are introduced to illustrate how the theory applies to phonological encoding processes. (Author/LMO)

Outlines a model for understanding the second-language reading process. Uses errors in comprehension to illustrate how the reading comprehension process works. Discusses pedagogical implications and suggestions for teaching students to develop and practice better comprehension strategies using think-alouds. (RS)
