Low-level visual features (e.g., motion, contrast) predict eye gaze during video viewing. The current study investigated the effect of narrative coherence on the extent to which low-level visual salience predicts eye gaze. Eye movements were recorded as 4-year-olds (n = 20) and adults (n = 20) watched a cohesive versus random sequence of video shots from a 4.5-min full vignette from Sesame Street. Overall, visual salience was a stronger predictor of gaze in adults than in children, especially when viewing a random shot sequence. The impact of narrative coherence on children's gaze was limited to the short period of time surrounding cuts to new video shots. The discussion considers potential direct effects of visual salience as well as incidental effects due to overlap between salient features and semantic content. The findings are also discussed in the context of developing video comprehension.
低水平视觉特征（例如，运动、对比度）可预测观看视频时的眼球注视。本研究考察了叙事连贯性对低水平视觉显著性预测眼球注视程度的影响。当 4 岁儿童（n=20）和成人（n=20）观看来自芝麻街 4.5 分钟完整小插曲的连贯与随机视频镜头序列时，记录了眼动。总体而言，视觉显著性对成人的注视预测作用强于儿童，尤其是在观看随机镜头序列时。叙事连贯性对儿童注视的影响仅限于新视频镜头切换前后的短时间内。讨论考虑了视觉显著性的潜在直接影响，以及由于显著特征和语义内容之间的重叠而产生的附带影响。研究结果还在发展视频理解的背景下进行了讨论。
