Clinical neuropsychological conceptualizations of aphasia: Perspectives from neurocognitive linguistics. Objective: To apply tenets of neurocognitive linguistics in order to develop a more comprehensive theoretical model of aphasic syndromes. Data Selection: A review of the neurocognitive linguistics literature, which itself has roots in neuroanatomy, neuroimaging, perceptual neuroscience, neurophysiology, psychology, and cognitive science, may provide the basis for a detailed conceptualization of the structural and functional underpinnings of linguistic systems in aphasics. Data Synthesis: Specifically, Lamb’s neurocognitive theory (1999, 2004, 2006) offers a connectionist perspective of the localization and interaction of linguistically relevant subsystems within a general model of human cognition. This model is based upon well-established findings by Broca, Wernicke, Luria, Geschwind, Goodglass, and key investigators in the fields of neuropsychology and neurology. By drawing upon Lamb’s theory, we posit a unified and visually explicit theoretical model of aphasic syndromes. We aim to: (i) introduce Lambian neurocognitive linguistics as a framework for systematizing current aphasiology research; (ii) expand upon Lamb’s work to develop a comprehensive theoretical model of aphasia and related syndromes; and (iii) incorporate current findings from functional neuroimaging and neuroscience research supporting the newly-developed model. Conclusions: Our proposed connectionist theoretical framework, informed by Lambian neurocognitive linguistics and recent findings in the neuroanatomy and neuroimaging literature, may offer a more systematic analysis of all types of aphasia within a general view of human cognition. The model is visually explicit regarding the neurological location of relevant brain areas and their interconnecting tracts. In sum, we will utilize an interdisciplinary approach to further refine the clinical neuropsychological conceptualizations of aphasia.
