This paper examines the automatic processing of the numerical magnitude of two-digit Arabic numbers using a Stroop-like task in school-aged children. Second, third, and fourth graders performed physical size judgments on pairs of two-digit numbers varying on both physical and numerical dimensions. To investigate the importance of synchrony between the speed of processing of the numerical magnitude and the physical dimensions on the size congruity effect (SCE), we used masked priming: numerical magnitude was subliminally primed in half of the trials, while neutral priming was used in the other half. The results indicate a SCE in physical judgments, providing the evidence of automatic access to the magnitude of two-digit numbers in children. This effect was modulated by the priming type, as a SCE only appeared when the numerical magnitude was primed. This suggests that young children needed a relative synchronization of numerical and physical dimensions to access the magnitude of two-digit numbers automatically.
本文使用类似斯特鲁普任务的方法，研究了学龄儿童对两位阿拉伯数字数值大小的自动加工过程。二、三、四年级的学生对在物理维度和数值维度上都有所变化的两位数对进行物理大小判断。为了探究数值大小加工速度与物理维度之间的同步性对大小一致性效应（SCE）的重要性，我们采用了掩蔽启动：在一半的试验中对数值大小进行阈下启动，而在另一半试验中使用中性启动。结果表明在物理判断中存在大小一致性效应，这为儿童能够自动获取两位数的数值大小提供了证据。这种效应受到启动类型的调节，因为只有在数值大小被启动时才会出现大小一致性效应。这表明幼儿需要数值维度和物理维度相对同步，才能自动获取两位数的数值大小。
