中文摘要： 运动认知加工包括逐线索搜索、根据线索的情境推理以及错误识别等阶段。运动员运动技能水平与运动认知加工能力呈正相关。目前运动心理学多从行为指标或者不同脑区激活程度进行分析，而没有探讨运动认知加工和脑网络连接间的关系。运动认知加工的脑网络连接模式研究可使我们更清楚认识复杂运动环境下大脑工作模式，也可使我们更全面了解认知加工的特点，有理论和实际应用价值。认知加工涉及额-顶网络和扣带-鳃盖网络等系统的相互连接与作用。额-顶网络负责逐线索控制、注意资源分配，而扣带-鳃盖网络负责任务相关目标维护和根据错误对控制进行调整。本研究以篮球项目为例，通过对高水平运动员在观看运动认知加工不同阶段，即多名运动员跑动方向的搜索、2对1进攻模式下防守队员反应正确性等视频时的行为数据以及相关脑网络连接模式的探讨，分析决定运动认知加工的关键因素，为运动训练实践服务，更为运动认知加工理论提供实践依据。

英文摘要： Motor cognitive processing consists of trial by trial search, cue-based contextual reasoning and error processing.The motor skill levels of athletes correlate positively with motor cognitive processing abilities. Behavioral indicators and cerebral activity have been widely reported in existed studies to explore motor cognitive processing, whose relation to network connectivity was barely discussed. The study on network connectivityof motor cognitive processing show theoretical and application value in the way it enables us to make clear the working mode of the brain in compound movement situations and to understand the features of cognitive processing comprehensively. Cognitive processing involves connectivity within and between two cognitive control networks: a fronto-parietal network for trial by trial control and attention allocation, and a cingulo-opercular network for maintaining task sets and the adjustment of control following errors. In the present study we will examine the crucial factor of cognitive processing by analysing the behavioral data and related network connectivity in high-level athletes who watch basketball videos demonstrating different cognitive processing phases, ie., the visual search of moving direction of multiple model players, the respond accuracy of defenders under 2 versu
