Abstract
There are few studies comparing the specificity of facial expression recognition in patients with cerebrovascular disease by brain damaged area. There is also no research comparing the top-down and the bottom-up information processing patterns in facial expression recognition of cerebrovascular disorder patients. This study classified the patients as follows:Frontal lobe Stroke (FS) group, Basal ganglia Stroke (BS) group, and Corona radiata Stroke (CS) group. Then, the Top-Down information processing Facial Expression Recognition Task (TDFERT) and the Bottom-Up information processing Facial Expression Recognition Task (BUFERT) were performed on the 3 groups, and the results of the facial expression recognition tasks were compared. Subsequently, the specificity of facial expression cognition in brain-damaged areas was investigated. As a result, the disgust and fear performance in the BUFERT was lower in the FS group and the BS group than in the CS group. The performance on the BUFERT was lower than the TDFERT in all three groups with disgust, indicating that the performance differs depending on the form of facial expression recognition task. On the other hand, happiness was high in both groups, implying that it is a more recognizable expression than other facial expressions.
