尽管有数百项研究描述了婴儿对实验刺激的视觉探索，但研究人员对婴儿在日常互动中看哪里知之甚少。目前的研究描述了研究移动婴儿自然互动过程中视觉行为的第一种方法。六个14个月大的婴儿戴上了头戴式眼球追踪器，记录下他们与母亲自由玩耍时的凝视。结果表明，婴儿的视觉探索是机会性的，取决于信息的可获得性和婴儿自身身体的约束。在婴儿指示的话语之后，很少有人看母亲的脸，但如果母亲坐在婴儿的眼睛水平，就更有可能。在手动动作和爬行过程中，注视目标是常见的，但在腿部运动过程中，注视障碍物的频率较低。
Despite hundreds of studies describing infants visual exploration of experimental stimuli, researchers know little about where infants look during everyday interactions. The current study describes the first method for studying visual behavior during natural interactions in mobile infants. Six 14-month-old infants wore a head-mounted eye-tracker that recorded gaze during free play with mothers. Results revealed that infants visual exploration is opportunistic and depends on the availability of information and the constraints of infants own bodies. Looks to mothers faces were rare following infant-directed utterances but more likely if mothers were sitting at infants eye level. Gaze toward the destination of infants hand movements was common during manual actions and crawling, but looks toward obstacles during leg movements were less frequent.
