Interpretation of non-verbal cues by people with and without TBI: understanding relationship intentions.

Background: Although long-term social challenges following traumatic brain injury (TBI) are well documented, the challenges of establishing new relationships following TBI are less understood.

Aims: To examine how the type of non-verbal cues produced by an unfamiliar communication partner impacts feelings of relationship closeness by people with and without TBI.

Methods & Procedures: In this quasi-experimental comparative mixed-group design, participants included 12 male heterosexual adults with moderate/severe TBI and 10 typical comparison peers.

P300 Event-Related Potentials Differentiate Better Performing Individuals With Traumatic Brain Injury: A Preliminary Study of Semantic Processing.

Objective: To measure the effect of traumatic brain injury on the cognitive processing of words, as measured by the P300, in a semantic categorization task.

Participants: Eight adults with a history of moderate to severe traumatic brain injury and 8 age- and gender-matched controls.

Design: A pilot study measuring cognitive event-related potentials in response to word pairs that were either in same or different semantic categories.
