在生命的第二年，婴儿表现出视频缺陷效应。也就是说，他们从电视演示中学到的东西明显少于从现场演示中学到的东西。我们预测，反复接触电视演示会增加来自电视的模仿，从而减少视频赤字效应。让6至18个月大的独立群体观看目标行动的现场或录像演示。24小时后测量对目标动作的模仿。视频片段的持续时间是现场演示的两倍。加倍曝光改善了12个月大的孩子的视频缺陷效应，但对15个月和18个月大的孩子没有。6个月大的婴儿模仿电视，但根本没有表现出视频缺陷效应，从现场和视频演示中学习得同样好。研究结果进行了讨论，在知觉的认知理论和双重表征理论。
During the second year of life, infants exhibit a video deficit effect. That is, they learn significantly less from a televised demonstration than they learn from a live demonstration. We predicted that repeated exposure to televised demonstrations would increase imitation from television, thereby reducing the video deficit effect. Independent groups of 6- to 18-month-olds were exposed to live or videotaped demonstrations of target actions. Imitation of the target actions was measured 24 hours later. The video segment duration was twice that of the live presentation. Doubling exposure ameliorated the video deficit effect for 12-month-olds but not for 15- and 18-month-olds. The 6-month-olds imitated from television but did not demonstrate a video deficit effect at all, learning equally well from a live and video demonstration. Findings are discussed in terms of the perceptual impoverishment theory and the dual representation theory.
