To discover whether visual serial search time for numbers differed significantly from time for letters, a repeated-measurements design was used with 24 undergraduate women. Performance on number targets 0 to 9 was significantly moe rapid than performance on the letter targets A to J, I to R, or Q to Z. By controlling confounding effects due to redundancy, the possibility that the outcomes might be related to the balance of linear and curvi-linear target features was strengthened.
为了探究数字的视觉序列搜索时间是否与字母的视觉序列搜索时间存在显著差异，对24名本科女生采用了重复测量设计。在0到9的数字目标上的表现明显比在A到J、I到R或Q到Z的字母目标上的表现更快。通过控制冗余带来的混杂效应，增强了结果可能与线性和曲线目标特征平衡相关的可能性。
