Abstract

bjectives: Traumatic brain injury (TBI) often precipitates socio-emotional problems which impinge on social relationships. Although socio-emotional impairments are debilitating the mechanisms underpinning these are poorly understood. Social interactions are dynamic yet research frequently employs static assessments. We investigated eye scan patterns of TBI and controls viewing static/dynamic facial expressions. Design: Factorial analysis investigated correct response, reaction time, fixation duration/count to areas of interest (eyes, nose and mouth) across six emotions (anger, disgust, fear, happy, sadness and surprise). Methods: 17 TBI participants were recruited from the NHS and age/gender matched controls were recruited using stratified opportunity sampling. Images from the Amsterdam Dynamic Facial Expression Set (ADFES) were presented on a Tobii T120 Eye Tracker screen. Multivariate and correlational methods were used to analyse data. Static Results: Controls displayed greater fixation durations; counts to eyes were more accurate and quicker identifying emotions than TBI participants. The TBI group focused more on the nose compared to controls. Higher scores on the ADFES correlated with quicker responses across all emotions for all participants and positive relationships between empathy, emotion recognition and fixation patterns were revealed. Gaze-patterns for the six emotions differed slightly between the groups although fearful faces induced more/longer fixations and happy faces the least/shortest fixations. Dynamic Results: Controls were more accurate at identifying emotions than the TBI group but no group differences were found for gaze-patterns. Happy faces induced more/longer fixations and sad faces the least/shortest fixations. A positive correlation between correct scores on the ADFES and empathy scores across all emotions for all participants was established. Conclusions: Irregular gaze-patterns could underpin some socio-emotional problems after TBI, highlighting the potential for innovative rehabilitation approaches. Visual strategies underlying the recognition of static/dynamic emotions may differ. The key limitation was the small sample size which will hopefully be rectified in future work
