摘　　要：将位置与方向两特征捆绑于一个空间符号,探讨该符号的编码与保持过程与注意的关系。方法:采用系列呈现方式,分别在学习阶段与保持阶段施加中央执行抑制分心任务,考察空间符号的材料类型、分心任务负荷、系列位置对位置、方向及其捆绑关系再认效率的影响。结果表明:(1)与学习阶段同步的分心任务对位置特征符号、方向特征符号和位置—方向捆绑符号产生了相近的削弱作用;(2)与学习阶段同步的分心任务对中间呈现的符号再认影响较大,对最先和最后呈现的符号再认影响较小;(3)与保持阶段同步的分心任务对各个系列位置上的捆绑特征符号再认影响较大。结果说明:(1)捆绑特征符号的编码所需注意资源不多于单一特征客体,对捆绑特征符号的编码是自动化的;(2)捆绑特征符号的暂时保持(8秒)需要较多的注意资源。Through two experiments, this research studied the effects of simultaneous central executive suppression on memory process of spatial symbols with location feature, direction feature, or location - direction binding features. Twenty - two undergraduates took part in the study. The first experiment adopted sequential presentation mode in order to study the effect of sub - task on memory efficiency of location symbols,direction symbols and location -direction binding symbols. The secondexperiment also adopted sequential presenta- tion mode and executed sub - task during symbols maintenance session simultaneously. The results showed that： （ 1 ） Sub - taskthat was simultaneous with training session exerted similar substantial detrimental effect on memory efficiency of location symbol, direction symbol and location - direction binding symbol. （2） Sub - task that was simultaneous with training session exerted a greater detrimental effect on memory efficiency of symbols presented in the middle serial positions, and exerted a smaller detrimental effect on memory efficiency of symbols presented at the first and at last. （3） Sub - task that was simultaneous with maintenance session exerted a great detrimental effect on memory efficiency of binding feature symbols at all 4 serial positions.
