传统上，外部显著性对凝视的外源性控制和知识和背景对凝视的内源性控制被视为竞争系统，婴儿期后期被视为加强对输入的变幻莫测的自上而下控制的时期。在这里，我们发现一岁的婴儿通过头部运动来控制持续的注意力，从而增加被关注物体的可见性。自由活动的1岁婴儿（n= 45）在探索相同物理尺寸的玩具时佩戴头戴式眼动仪和头部运动传感器。物体的视觉大小，一个有据可查的显著性，随着婴儿的时刻到时刻的姿势和头部运动而自然变化。对物体的持续注意力的特征在于对头部运动的严格控制，这种运动创造并稳定了持续注意力所关注的物体的视觉尺寸优势。研究结果显示了外源性和内源性注意力系统之间的合作，并提出了有关持续视觉注意力发展的新假设。
Traditionally, the exogenous control of gaze by external saliencies and the endogenous control of gaze by knowledge and context have been viewed as competing systems, with late infancy seen as a period of strengthening top‐down control over the vagaries of the input. Here we found that one‐year‐old infants control sustained attention through head movements that increase the visibility of the attended object. Freely moving one‐year‐old infants (n= 45) wore head‐mounted eye trackers and head motion sensors while exploring sets of toys of the same physical size. The visual size of the objects, a well‐documented salience, varied naturally with the infant's moment‐to‐moment posture and head movements. Sustained attention to an object was characterized by the tight control of head movements that created and then stabilized a visual size advantage for the attended object for sustained attention. The findings show collaboration between exogenous and endogenous attentional systems and suggest new hypotheses about the development of sustained visual attention.
