Aphasia is an acquired language impairment that affects over 1 million individuals, the majority of whom are over age 65 (). This disorder has typically been conceptualized within a cognitive neuroscience framework, but a behavioral interpretation of aphasia is also possible. analysis of verbal behavior proposes a framework of verbal operants that can be integrated with the work of and to describe the language difficulties individuals with aphasia experience. Using this synthesis of models, we propose a new taxonomy of aphasia based on the observed deficit relations. Assessment and treatment implications are also discussed.
