本研究采用数字-Stroop范式追踪阿拉伯数字自动和有意加工的发展变化。在研究1中，大学生比较了阿拉伯数字的数字或物理大小变化沿着两个维度。在研究2中，对一年级学生（平均年龄= 6岁6个月）、三年级学生（平均年龄= 8岁1个月）和五年级学生（平均年龄= 10岁3个月）进行了测试，以检查数字和身体比较的发育变化。在数字比较任务中，在所有年龄段都发现了大小一致性效应（即，相对于中性对照，促进一致的物理尺寸，并且干扰不一致的尺寸，数值比较）。协助和干涉的模式。在物理比较任务中，物理和数字大小之间的不协调只影响年龄较大的儿童和成人。这些结果有力地表明，数字加工的自动化是随着数字技能的发展而逐步实现的。(C)北京大学出版社.
This study traces developmental changes in automatic and intentional processing of Arabic numerals using a numerical-Stroop paradigm. In Study 1, university students compared the numerical or physical size of Arabic numerals varying along both dimensions. in Study 2, first graders (mean age = 6 years 6 months), third graders (mean age - 8 years 1 months), and fifth graders (mean age = 10 years 3 months) were tested to examine developmental changes in numerical and physical comparisons. In the numerical comparison task, a size congruity effect was found at all ages (i.e., relative to a neutral control, congruent physical sizes facilitated, and incongruent sizes interfered with, the numerical comparison). The pattern of facilitation and interference. however, was modulated by age- In the physical comparison task, the incongruity between physical and numerical size affected only older children and adults. These findings strongly suggest that the automatization in number processing is achieved gradually us numerical skills progress. (C) 2000 Academic Press.
