Clinical Linguistics

Clinical Linguistics: Speech and Language Disorders


This theme investigates language impairments in children and adults; how they originate, and how they are diagnosed and treated.

With expertise spanning speech and language pathology, linguistics, phonetics and psychology, our research in clinical linguistics, speech and language, is strongly interdisciplinary and involves substantial collaborations both within Newcastle and beyond.

We address the universal and language-specific factors underpinning development and disorder, the psycholinguistic processes contributing to outcomes in typical and special populations, and intervention for disorders.

In adult acquired disorders, we focus on language processing in a variety of disorders including aphasia, dementia and motor speech disorders.

Our principal goals overall are:

  • the development of theory underpinning acquired speech and language disorder
  • the application of theory to clinical practice
  • the development of an evidence base in which theoretically motivated assessments and therapies are developed and evaluated.
