Suppression and Narrative Time Shifts in Adults with Right-Hemisphere Brain Damage
Scharp, Victoria L.; Tompkins, Connie A.
American Journal of Speech-Language Pathology, v22 n2 pS256-S267 May 2013
Purpose: This study examined the functioning of a central comprehension mechanism, suppression, in adults with right-hemisphere damage (RHD) while they processed narratives that cued a shift in time frame. In normal language comprehension, mental activation of concepts from a prior time frame is suppressed. The (re)activation of information following a time frame shift was also assessed. Method: Twenty adults (12 RHD; 8 non brain-damaged) completed a speeded word recognition task while listening to narratives in 2 conditions: shift ("an hour later") and no shift ("a moment later"). Results: There was no group difference in suppression for response time proportion data (shift/no shift), but cluster analyses identified a suppression deficit in 8 of the adults with RHD. There was overlap in suppression function at the narrative and lexical levels. The group with RHD was significantly delayed in mentally (re)activating new information after a time shift cue. Conclusion: Results underscore the generality of suppression functioning in adults with RHD. As such, treatment for a suppression deficit at one level may generalize to another level. An apparent independence of suppression and activation deficits suggests that each may need separate treatment. A better understanding of the nature and boundary conditions of suppression and activation deficits should better inform clinical decisions. (Contains 3 tables.)
