Purpose: Cognitive communication deficits can be difficult to assess in individuals with mild traumatic brain injury (mTBI). However, the use of discourse analysis as a direct and sensitive metric of cognitive communication skills has shown promising clinical utility for other TBI severity levels. This exploratory study investigated discourse production in service members and veterans (SMVs) with uncomplicated mTBI with and without posttraumatic stress disorder (PTSD) and SMVs with neither mTBI or PTSD.

The current study brings together analysis of two speech coordination strategies, entrainment and compensation of articulation, in a preliminary investigation into whether strategy organization is shaped by a challenging communicative context-conversing with a person who has a communication disorder. Method As an initial clinical test case, an automated measure of articulatory precision was analyzed in a corpus of spoken dialogue, where a confederate conversed with participants with traumatic brain injury ( = 28) and participants with no brain injury ( = 48).

Generalization of treatment to untrained materials and to discourse production was also analyzed, as was the durability of the treatment effect.
Method: Participants with aphasia were assessed using standardized measures and discourse tasks at 3 to 4 time points to document behavioral changes throughout each of two 30-hr treatment periods of constraint-induced language therapy.
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 examined the narrative discourse production and executive function (EF) abilities of 46 neuro-typical adults (18-98 years old). Two questions were addressed: Is the analysis of narrative structure sensitive to changes associated with aging? & What is the relationship between measures of narrative structure and EF? Narratives were elicited under two conditions and narrative structure was analyzed for the presence of organizing story grammar elements. Narrative structure was significantly correlated with age as well as linguistic and non-linguistic measures of EF.

Effective conversational discourse requires a complex interaction of linguistic, cognitive, and social abilities [6]. Reduced attention and concentration are among the most common cognitive sequela following CHI [39].

Non-linguistic cognitive skills have recently become an area of focus in aphasia research. One skill that has received in-depth investigation is the role of attention in language tasks. In applying the resource allocation theory to aphasic language deficits, researchers have described performance variablity in language tasks that may result from insufficient capacity, inefficient allocation, or inappropriate allocation of attentional resources [16].

The sensitivity of discourse analyses for delineating subtle cognitive-communicative deficits is well established in the research literature. A variety of useful monologic and conversational discourse measures have been identified including productivity, efficiency, content accuracy and organization, story grammar and coherence, and topic management.

Research demonstrates that auditory and visual information are integrated for speech perception. The strongest evidence of this cross-modal integration is the McGurk effect.

A sample of six stories was obtained with tasks of cartoon-elicited story-telling and auditory-oral retelling. We found deficits in the clinical group with respect to referential cohesion, logical coherence, and accuracy of narration.

Participants were classified, on the basis of their socioeconomic status (SES), as professional, skilled worker, or unskilled worker. Narratives were analyzed using five discourse measures at the levels of sentence production, intersentential cohesion, and story grammar.

However, there is a paucity of information relating to the treatment of such deficits. The present study investigated the treatment of discourse production deficits, specifically story grammar ability, in an individual with TBI.
