| Outline of Final Research Achievements |
This study investigated assessment techniques and rehabilitation outcomes of facial expression recognition deficits in head-injured patients by using behavioral and brain activity measures. In behavioral assessment task the recognition threshold values for six basic facial emotions except for “happy” were significantly higher for head-injured patients than for age-matched normal participants. Correlation analysis revealed that in head-injured patients the recognition threshold values for facial emotions were significantly correlated with memory, executive function and social behavior measures. In addition, head-injured patients did not show normal face-specific N170 effect in event-related potential (ERP) assessment task, suggesting a dysfunction of early facial perceptual processing. Intensive cognitive rehabilitation of facial expression recognition influenced not only behavioral measures but also face-specific ERP component (N170) behavior in chronic head-injured patients.
