Discourse Analysis of Humor After Traumatic Brain Injury.

Purpose Individuals with cognitive communication difficulties after traumatic brain injury (TBI) often experience difficulties with social communication. Humor is a sociolinguistic skill that requires social, cognitive, emotional, and behavioral skills and, when used effectively, may serve to enhance one's social relationships. There is a paucity of research related to the use of humor in individuals with TBI. This study categorizes humor use in individuals with cognitive communication difficulties after TBI and examines the linguistic construction of these humorous exchanges. Method The humorous exchanges of nine individuals who had cognitive communication difficulties after a moderate-to-severe TBI were examined. Conversations were collected from a community-based communication skills group, categorized using thematic analysis methods, and examined linguistically using the discourse analysis tools of systemic functional linguistics. Results All participants demonstrated the ability to use a variety of categories of humor, and discourse analysis methods revealed humor use as a strength for engaging with others. Examples of such engagement include use of humor to elicit attention, assert authority, share information, acknowledge shared difficulties, and demonstrate affiliation toward their communication partners. Conclusions Discourse analysis of humor can provide speech-language pathologists with important information about the linguistic strengths of individuals with cognitive communication difficulties. This has important implications for clinical service provision.
