In two experiments, we showed that irrelevant numerical information influenced the speed of sentence-picture verification. Participants were asked to verify whether the concept mentioned in a sentence matched the object presented in a subsequent picture. Concurrently, the number word attached to the concept in the sentence and the quantity of objects presented in the picture were manipulated (numerical congruency). The number of objects varied from one to four. In Experiment 1, participants read statements such as three dogs. In Experiment 2, they read sentences such as three dogs were wandering in the street. In both experiments, the verification speed revealed the interaction between response and numerical congruency. The verification times for concept-object match were faster when there was also numerical congruence (compared with incongruence) between the number word and quantity. On the other hand, there was no difference between numerical congruence and incongruence when the concept and object mismatched. The results are interpreted as evidence for the symbol grounding of number words in perceptual representation of small quantities, that is, quantities falling in the subitization range.
在两项实验中，我们发现无关的数字信息会影响句子-图片验证的速度。参与者被要求验证句子中提到的概念是否与随后呈现的图片中的物体相匹配。同时，句子中与概念相关的数字词以及图片中呈现的物体数量被加以操控（数字一致性）。物体的数量从一到四不等。在实验1中，参与者阅读诸如“三只狗”这样的陈述。在实验2中，他们阅读诸如“三只狗在街上闲逛”这样的句子。在两项实验中，验证速度都显示出反应与数字一致性之间的相互作用。当数字词和数量之间也存在数字一致性（与不一致相比）时，概念-物体匹配的验证时间更快。另一方面，当概念和物体不匹配时，数字一致性和不一致性之间没有差异。这些结果被解释为数字词在少量感知表征中的符号基础的证据，也就是说，数量处于一眼识数范围内。
