摘　　要：个体的认知活动总是在不同的任务之间转换。有关任务转换中的执行控制的研究,一般把任务转换分为同时性程序和继时性程序两种类型。目前主要有 6 种理论解释:“从注意到行动”理论(ATA)、“前额叶执行”理论(FLE)、执行控制阶段模型(SMEC)、“策略性反应—延迟”理论(SRD)、两成分模型(TCM)以及平行分配加工理论(PDP)。这些理论从不同的角度阐述了任务转换中的执行控制机制。它们之间相对独立而又紧密联系,为探讨个体的认知机制提供了重要的理论基础。Individuals’cognitive abilities are always shifted among different tasks. As to the researches of the executive control in task switching, usually the switching procedures can be divided into two categories: simultaneous-tasks procedure and successive-tasks procedure. At present, in the researches of the executive control in task switching, there are mainly 6 theoretical explanations: Attention-to-Action(ATA) theory, Frontal-Lobe Executive(FLE) theory, Stage Model of Executive Control(SMEC), Strategic Response-Deferment theory(SRD), Two-Component Model(TCM) and Parallel Distribution Process(PDP) theory. These theories explain the executive control mechanism in task switching from different points, and they are relative independent but correlated with each other to some degree, providing an important theoretical base for exploring individuals’cognitive processing.
