摘　　要：在同一实验条件下采用干扰效应和负启动效应双指标考察了三种不同类型工作记忆(WM)负载对特性干扰子加工的影响,旨在求证胡耿丹等人从位置干扰子加工所提出的"双重作用机制"是否适用于特性干扰子加工,以及对Park等人的负载特异机制观点所做的拓展和完善在特性干扰子范畴内是否正确。结果显示:(1)WM负载对特性干扰子的加工亦存在双重作用机制,提示双重作用机制在单一WM负载范围内具有普适性;(2)当目标刺激与干扰子刺激的属性一致时,无论是在位置干扰子还是在特性干扰子视角下Park等人的负载特异机制观点均可一致地被拓展和完善。Hu Gengdan et al put forward the ＂dual acting mechanism＂viewpoint,expanding and improving Park et al＇s cognitive control mechanism viewpoint from the position distractor processing.To examine whether or not the dual acting mechanism was the same with the identity distractor processing,and whether or not the expansion and improvement about Park et al＇s viewpoint was true in the range of identity distractors,the influence of three types of working memory（WM）loads on identity distractors was observed and studied by double indexes of interference effect and negative priming effect under the same experiment condition.The results showed that（1）Dual acting mechanism could also be the same with the identity distractor processing,which suggested the dual acting mechanism had universality in the range of single WM loads.（2）When the target stimulus and distractor stimulus were in the same attribute,Park et al＇s cognitive control mechanism viewpoint could be synchronously expanded and improved in both the visual angle of position distractor processing and the visual angle of identity distractor processing.
