Analyses of eye-fixation data in adults suggested that the carry effect in addition is determined by the unit digits of the summands. Correspondingly, we recorded children's eye fixation behavior in a choice reaction paradigm. As for adults the carry effect was most pronounced on the unit digits of the summands. However, children's fixation pattern differed reliably from that of adults in other important aspects. While these data suggested common processes in children and adults for performing a carry in mental addition, children's eye fixation data indicated a less flexible processing style primarily based on calculating the correct result.
对成年人眼动注视数据的分析表明，进位效应还由加数的个位数决定。相应地，我们在选择反应范式中记录了儿童的眼动注视行为。与成年人一样，进位效应在加数的个位数上最为明显。然而，儿童的注视模式在其他重要方面与成年人有可靠的差异。虽然这些数据表明儿童和成年人在进行心算加法时存在共同的过程，但儿童的眼动注视数据表明其处理方式较不灵活，主要基于计算正确结果。
