我们调查了婴儿对时空结构的敏感性。在实验1中，圆圈出现在一个统计定义的空间模式。在测试中，11个月大的婴儿，而不是8个月大的婴儿，在一个新的空间序列上看得更久。实验2呈现不同的颜色/形状刺激，但只有位置序列在测试过程中被违反; 8个月大的首选新的空间结构，但5个月大的没有。在实验3中，位置，但不是颜色/形状配对是恒定的，在测试中，5个月大的孩子表现出新奇的偏好。实验4研究了“在线学习”：我们记录了8个月大的婴儿观看时空序列的眼球运动。对可预测位置的扫视延迟减少。我们认为，时序统计信息的空间关系成为婴儿出生后的第一年，辅助多种线索。
We investigated infants' sensitivity to spatiotemporal structure. In Experiment 1, circles appeared in a statistically defined spatial pattern. At test 11-month-olds, but not 8-month-olds, looked longer at a novel spatial sequence. Experiment 2 presented different color/shape stimuli, but only the location sequence was violated during test; 8-month-olds preferred the novel spatial structure, but 5-month-olds did not. In Experiment 3, the locations but not color/shape pairings were constant at test; 5-month-olds showed a novelty preference. Experiment 4 examined "online learning": We recorded eye movements of 8-month-olds watching a spatiotemporal sequence. Saccade latencies to predictable locations decreased. We argue that temporal order statistics involving informative spatial relations become available to infants during the first year after birth, assisted by multiple cues.
