2 experiments with 18-week-old infants employed an interference paradigm to study infant visual memory. The infants were habituated to a repeated stimulus, given several trials with 1 or more interpolated stimuli, and then tested for recognition of the original stimulus. In Experiment 1, both amount of exposure and the similarity of the potentially interfering material to the original habituation stimulus were manipulated. Neither produced a significant interference effect, although some effect may have been shown by subjects who habituated to the interference stimult did demonstrate more clearly long-term retention of the originally remembered material. It was concluded from both studies that infant visual memory is a robust phenomenon, relatively immune to interference under most conditions.
两项针对18周龄婴儿的实验采用干扰范式来研究婴儿的视觉记忆。婴儿先对重复刺激形成习惯化，再进行几次包含1个或多个插入刺激的试验，然后测试其对原始刺激的识别能力。在实验1中，研究者对曝光量以及潜在干扰材料与原始习惯化刺激的相似度这两个因素进行了操控。虽然对干扰刺激形成习惯化的受试者可能表现出了一定效果，即更清晰地展现出对原始记忆材料的长期保持，但这两个因素均未产生显著的干扰效应。两项研究均得出结论：婴儿视觉记忆是一种强大的现象，在大多数情况下相对不易受到干扰。
