摘　　要：采用专家-新手范式,运用事件相关电位记录技术,探讨了不同情境下优秀散打运动员预判能力及其神经活动特征。结果发现:优秀散打运动员预判速度快,准确率高,主要与其预判早期精细加工动用的心理资源多、预判晚期大脑皮层激活速度快、动用的心理资源少有关;散打进攻策略预判诱发的ERP成分主要有P1、N1和P3;不同情境影响预判信息加工的速度和准确性;与图片预判相比,视频预判速度慢,准确率高,其可能机制是认知加工时大脑激活时程较长、早期动用的心理资源较少、晚期动用的心理资源较多。This research adopts expert-novice paradigm, using the event related potential recording technique, and discusses the different situations of excellent Sanda athletes have high anticipation ability and its characteristics of neural activity. Resuits： excellent Sanda athletes anticipation speed, and high accuracy, fine machining of main predictions with early use of psychological resources, anticipation late cerebral cortex activation speed, less use of psychological resources; Sanda attack strategy anticipation induced the bio-pin ERP P1 and N1 and P3 ; Different situation influence forecasting information processing speed and accuracy; Compared with pictures anticipation, video anticipation is slow, accuracy is high, and its possible mechanism is that the cognitive processing brain activation time history is longer, the early use of psychological resources is less.the late use psychological resources is more late.
