摘要:
 工作记忆中央执行成分在计算加工的诸多过程中发挥重要影响。以82名大学生为被试，采用双任务实验范式考察工作记忆中央执行成分对估算表现的影响。结果发现：1)估算过程需要中央执行成分的参与，增加中央执行成分负荷会导致估算准确率下降；2)无论是否增加中央执行负荷，问题大小效应在估算中均不明显；3)乘法个位数大小顺序会影响估算值的准确性，在有中央执行负荷时数字顺序效应明显。
Abstract:
 Central executive component plays a major impact in many processes of calculation.In the present study，82 students were tested in the dual-task paradigm to examine the role of central executive component of working memory on adults’ estimation performance.The results showed that：1)estimation process required the involvement of the central executive component，increasing the load on the central executive component would lead to decline in the accuracy of estimates；2)whether the central executive load increased or not，the problem size effect in the estimates were not significant；3)the order of single unit size in multiplication estimation would affect the accuracy of estimates，and the numerical order effect with central executive load was obvious.
