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…

Background: Speech and language researchers study phonological acquisition and evaluate the errors that children make to understand this complex process. This information provides clinicians with a scientific reference for better assessment and intervention services to children with articulation/phonological disorders. Urdu is a language spoken by…

In particular, we investigate whether children's accuracy…
