最近的研究报告说，学龄前婴儿能够区分在特定情态中呈现的大量集合，然而，仍然存在争议；关于他们是否能够执行多模态数量匹配，即将不同感觉模态呈现的集合的数量联系起来。本研究采用违背期望范式对婴幼儿小数的听觉-视觉多模态匹配进行了研究。在熟悉了几个物体连续撞击表面的事件后，6个月大的婴儿交替地呈现两种和三种音调，而每个物体的运动都隐藏在不透明的屏幕后面。然后将屏幕移开，露出两个或三个物体。结果表明，无论声音呈现的频率或持续时间如何，婴儿在数字非等效事件（三音/两个物体和两音/三个物体事件）上的注视时间明显长于数字等效事件（两音/两个物体和三音/三个物体事件）。这些发现表明，婴儿有能力进行小数字的多模态匹配，并且他们可能拥有超出感觉模态的数字抽象表征。
Recent studies have reported that preverbal infants are able to discriminate between numerosities of sets presented within a particular modality There is still debate, however; over whether they are able to perform intermodal numerosity matching, i.e. to relate numerosities of sets presented with different sensory modalities. The present study investigated auditory-visual intermodal matching of small numerosities in infancy by using a violation-of-expectation paradigm. After being familiarized with events of a few objects impacting a surface successively, 6-month-old infants were alternatively presented with two and three tones While the movement of each object remained hidden behind an opaque screen. The screen Was then removed to reveal either two or three objects. Results showed that the infants looked significantly longer at the numerically nonequivalent events (the three-tone/two-object and the two-tone/three-object events) than at the numerically equivalent events (the two-tone/two-object and the three-tone/three-object events) irrespective of the rate or duration of auditory tones presented. These findings suggest that infants are capable of performing intermodal matching of small numerosities and that they might possess abstract representations of numerosity beyond sensory modalities.
