Many studies have shown that solving addition and subtraction problems can induce overt shifts of spatial attention. In particular, right-side targets are detected faster than left-side targets when preceded by an addition operation, while left-side targets are detected faster than right-side targets when preceded by a subtraction operation. However, the interaction between space and arithmetic in multiplication or division is hardly studied and remains controversial. In order to make a strong case for the interaction between space and mental arithmetic, we attempted to replicate the spatial-arithmetic association in addition and subtraction (Experiment 1), and at the same time investigated whether shift of spatial attention would also be induced by multiplication or division operations (Experiment 2). We found that solving addition problems facilitated the detection of right-side targets, whereas left-side targets were detected faster after solving subtraction problems. However, no interaction between space and arithmetic operation was observed in multiplication or division. The implication of these findings is discussed.
许多研究表明，解决加减法问题会引发空间注意力的明显转移。具体而言，当加法运算在前时，右侧目标的检测速度比左侧目标快，而当减法运算在前时，左侧目标的检测速度比右侧目标快。然而，乘法或除法中空间与算术之间的相互作用几乎未被研究，且仍存在争议。为了有力证明空间与心算之间的相互作用，我们试图在加减法中复制空间 - 算术关联（实验1），同时研究乘法或除法运算是否也会引发空间注意力的转移（实验2）。我们发现，解决加法问题有助于右侧目标的检测，而解决减法问题后左侧目标的检测速度更快。然而，在乘法或除法中未观察到空间与算术运算之间的相互作用。本文讨论了这些发现的意义。
