In search tasks that are otherwise identical, adults process strings of letters differently from strings of other shapes (Hammond & Green, 1982). This result has implications for word recognition and reading, and it is important to establish its developmental sequence. Two groups of primary school children and an adult control group completed a similar visual search task: determining whether a predesignated target character occurred in a subsequently displayed character string. The mean search latency decreased with age, and the results showed a qualitative difference in the processing of letters and shapes for even the youngest group. However, the left to right processing of letter strings does become more established with age.
在其他方面都相同的搜索任务中，成年人处理字母串的方式与处理其他形状的字符串不同（哈蒙德和格林，1982年）。这一结果对单词识别和阅读有影响，确定其发展顺序很重要。两组小学生和一个成人对照组完成了一项类似的视觉搜索任务：确定一个预先指定的目标字符是否出现在随后显示的字符串中。平均搜索潜伏期随年龄增长而缩短，结果表明，即使是最年幼的组在处理字母和形状时也存在质的差异。然而，字母串从左到右的处理方式确实会随着年龄的增长而更加固定。
