物体的颜色知识和运动知识的独立性表征

摘要

Objective To investigate the relationship between the presentation of color knowledge and the motion knowledge.Methods 39 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.Results Group 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.Conclusion Color knowledge and motion knowledge are represented independently in the brain, which is consistent with the distributed semantic memory theory.%目的 探讨物体颜色知识和运动知识在大脑中的表征关系.方法 对39例脑损伤患者和39例正常对照组进行颜色知识属性判断测验和运动知识属性判断测验.对数据进行群组分析和个体分析.结果 群组分析显示,患者在这两个任务上的正确率显著正相关;个体分析发现,5例患者在颜色知识属性判断上的成绩显著好于运动知识属性判断,而另外5例患者在运动知识属性判断上的成绩显著好于颜色知识属性判断.结论 物体的颜色知识和运动知识在大脑中存在相对独立的表征,与大脑中概念知识的分布式表征理论相符.
