这项研究提供了第一个证据，证明学龄前儿童在数字匹配任务中，当给予关于数字的多感觉信息而不是单一感觉信息时，表现得更准确。三到五岁的孩子学会了在触摸屏电脑上玩数字匹配游戏，要求他们将一个样本数字与一个数字等价的选项数字进行匹配。样本包括一些试验的一系列视觉正方形，其他试验的一系列听觉音调，以及还有一些试验的同步正方形和音调。当提供任何一种单一感觉样本时，儿童在这一匹配任务中的表现是偶然的，但当提供多感觉样本时，儿童的表现显著提高。在单感觉和多感觉试验类型之间没有速度和准确性的折衷。因此，这些发现表明，感觉间冗余可能会提高幼儿匹配数字的能力。
This study presents the first evidence that preschool children perform more accurately in a numerical matching task when given multisensory rather than unisensory information about number. Three- to 5-year-old children learned to play a numerical matching game on a touchscreen computer, which asked them to match a sample numerosity with a numerically equivalent choice numerosity. Samples consisted of a series of visual squares on some trials, a series of auditory tones on other trials, and synchronized squares and tones on still other trials. Children performed at chance on this matching task when provided with either type of unisensory sample, but improved significantly when provided with multisensory samples. There was no speed-accuracy tradeoff between unisensory and multisensory trial types. Thus, these findings suggest that intersensory redundancy may improve young children's abilities to match numerosities.
