Forty-eight newborn infants were tested in one of three multimodal stimulus conditions, in which auditory quantities were presented alongside visual object arrays in two test trials. These tests varied with respect to which side (either left or right) numerically matched the auditory number. The infants looked longer to the test trials in which the left side of the visual display exhibited a quantity that matched the presented auditory quantity. This study provides the first evidence for an untrained, innate bias for humans to preferentially process quantity information presented in the left field of vision.
48 名新生儿在三种多模式刺激条件中的一种条件下接受了测试，在两种测试试验中，听觉数量与视觉物体阵列同时呈现。这些测试在哪个侧面对应（左或右）与听觉数量匹配方面有所不同。当视觉显示的左侧显示与呈现的听觉数量匹配的数量时，婴儿会更长时间地注视测试试验。这项研究首次提供了证据，证明人类有一种未经训练的先天偏好，即优先处理左视野中呈现的数量信息。
