摘要

反应码的空间-数值关联效应(SNARC)指的是小数字促进左反应，而大数字促进右反应的发现。在7岁、8岁和9岁的儿童以及成年人中研究了这种空间关联的发展，使用了一个数字大小对完成任务至关重要的任务和另一个数字大小无关的任务。当数量大小是必要的，SNARC效应发现在所有年龄组。但当数字大小不相关时，SNARC效应仅在9岁儿童和成年人中被发现。这些结果表明，(a) 7岁儿童表示数字大小的方式与成人相似，(b)当感知阿拉伯数字时，儿童在9岁左右就能自动获取数字大小信息。

Developing access to number magnitude: A study of the SNARC effect in 7- to 9-year-olds

The SNARC (spatial–numerical association of response codes) effect refers to the finding that small numbers facilitate left responses, whereas larger numbers facilitate right responses. The development of this spatial association was studied in 7-, 8-, and 9-year-olds, as well as in adults, using a task where number magnitude was essential to perform the task and another task where number magnitude was irrelevant. When number magnitude was essential, a SNARC effect was found in all age groups. But when number magnitude was irrelevant, a SNARC effect was found only in 9-year-olds and adults. These results are taken to suggest that (a) 7-year-olds represent number magnitudes in a way similar to that of adults and that (b) when perceiving Arabic numerals, children have developed automatic access to magnitude information by around 9 years of age.
