Abstract
Acquired language disorder is a common consequence of stroke and traumatic
brain injury (TBI). Following the logogen model, this study investigated word processing abilities of
post-stroke and post-TBI patients. Within- and between-group differences in word comprehension,
naming, and reading were observed, as well as predominant errors in performance. Twenty-two post-stroke
and 22 post-TBI patients were tested using tasks from the Comprehensive Aphasia Test-HR
(CAT-HR). Post-TBI patients outperformed post-stroke patients in naming and reading. Both groups
exhibited neologisms, phonological, semantic and unrelated errors, although in different proportions.
In word comprehension and naming, post-TBI patients primarily exhibited semantic errors, whereas
post-stroke patients had equally distributed phonological and semantic errors. In reading, both groups
predominantly produced phonological errors. Error distribution differed only in naming, with post-
TBI patients exhibiting more semantic errors than post-stroke patients. Therefore, performance in
naming differentiated these groups most. Although error analysis is rather insightful, one cannot
expect a particular profile of language disturbances in post-stroke and post-TBI patients. The findings
obtained bear concrete clinical implications, especially those related to the role and meaning of the
errors produced by the patient to determine the exact location of the processing deficits.
