Abstract

Some suggest that traumatic brain injury (TBI) produces dissociation between the macrolinguistic and microlinguistic levels of discourse production. This assumption is based primarily on studies that have found preserved intersentential cohesion and/or intra-sentential processing in narratives produced by these individuals. However, few studies exist, if any, that have investigated the relationship between these processes in TBI speakers who do demonstrate such microlinguistic impairments. This study investigated the relationship between impairments of intersentential cohesion and intra-sentential processing in the discourse of 15 speakers with severe TBI. The results demonstrated a significant relationship between the production of cohesive ties and instances of intra-sentential impairment that suggests that utilization of resources for adequate cohesion appears to negatively affect intra-sentential processing following TBI. We propose that macrolinguistic and microlinguistic processes are not independent of one another, as has been proposed, but share cognitive resources that support the planning and production of both local (microlinguistic) and long-distance (macrolinguistic) relationships expressed through discourse.
