Item Perception and expression of emotion in TBI : identification of emotion, recognition of emotional ambiguity, and emotional verbal fluency(2019-08-08) Czimskey, Natalie Marie; Marquardt, Thomas P.; Henry, Maya L; Sussman, Harvey M; Fingerman, Karen LCommunication and social integration require effective emotional, cognitive, and language processing within the brain. Traumatic brain injury (TBI) results in impaired emotion processing in a variety of contexts including emotion encoded in facial appearance, prosody, and the linguistic content of messages. Individuals with TBI report difficulty in relationship maintenance and social integration post injury as a result of impairments in communication. Emotional communication is frequently ambiguous or incongruous in presentation and its accurate perception is vital to effective communication and interpersonal relationships. Recognition of ambiguity in emotional communication has not been investigated in individuals with TBI. This study evaluated differences in emotion perception and expression between 12 individuals with TBI and 24 individuals without TBI. Three tasks were utilized: 1) emotion identification in 34 congruous and 66 incongruous emotional sentences, 2) identification of ambiguity in emotion in 34 congruous and 66 incongruous emotional sentences, and 3) verbal fluency with emotion category generation. Participants without brain injury demonstrated increased accuracy in emotion identification and emotional ambiguity identification. Participants without brain injury generated more responses in all verbal fluency categories. Both groups were more accurate in emotion identification of congruous sentences, and more accurate in ambiguity identification in congruous sentences. Participants with TBI showed impaired identification of emotion in sentences, impaired identification of emotional ambiguity in sentences, and a reduced number of responses in verbal fluency tasks when compared to individuals without brain injury. Results are discussed in terms of impact on effective communication for individuals with TBI. These findings support that individuals with TBI are impaired in perception of emotion, including ambiguity in emotional communication, and show reduced output in verbal fluency tasks.
