Aphasia - Definitions Flashcards
Major distinctions between aphasia and disorders that resemble it (Darley, 1982)
Aphasia is language specific, aphasia is not a speech disorder, aphasia is not modality bound, does not relate to the etiology of brain damage
Schuell & Jenkins, 1959
• The core deficit in aphasia is a unitary, underlying language deficit, best described along a severity continuum rather than a linguistic one
Wepman & Van Pelt (1955)
the same neural structures perform symbolic and transmission functions, but functions can be differentiated based on symptoms (aphasia vs. apraxia/agnosia)
Brown (1968)
Central Language Processor (CLP): three-level speech and language processing mechanism
o CLP must have
Access to semantic lexicon, grammar of language
Ability to store sufficient amount of incoming language to process/recall in the absence of the signal
Capacity to continuously select most important information from continuous flow of competing internal thought/external stimuli
Hageman, McNeil, Rucci-Zimmer, & Cariski, 1982
o Performance in aphasia is variable not only across days/testing sessions, but can be minute to minute
Miyake, Carpenter, & Just, 1994
o Normal to aphasia continuum – people without aphasia can be made to perform like PWA under certain circumstances
Linebaugh, Coakley, Arrington, & Racy, 1979
o Aphasia can be transient: secondary to epilepsy, can be exacerbated by or only observed following seizure
Utman, Blumstein & Sullivan 2001
o PWA exhibit priming effects
Helm-Estabrooks, 2002
o Evidence that severity of linguistic deficits cannot be predicted based on the severity of non-linguistic cognitive deficits, and/or vice-versa
Murray, 1999
o The relationship between language and non-linguistic aspects of cognitive is varied
many agree that PWA exhibit limited resources and/or disrupted resource allocation
