Abstract: ObjectiveTo investigate the relationship between the presentation of color knowledge and the motion knowledge. Methods39 patients with brain injury and 39 healthy volunteers were recruited in this study. They were tested with the color attribute judgment task and the motion attribute judgment task. Group analysis and case analysis were taken to investigate the correlation and dissociation between these two tasks. ResultsGroup analysis revealed a positive correlation between the color attribute judgment and the motion attribute judgment task. As for case analysis, 5 patients showed significantly better performance on color attribution judgment than motion attribution judgment. In contrast, another 5 patients showed significantly better performance on motion attribute judgment than color attribute judgment. ConclusionColor knowledge and motion knowledge are represented independently in the brain, which is consistent with the distributed semantic memory theory.
