视觉注意力的理论表明，诸如警觉性、空间定向、对物体特征的注意和内源性控制等子功能的级联发展。在这里，我们的目的是跟踪婴儿的视觉发育步骤，从一个主要的外源性到更多的内源性控制的处理方式在他们的生命的第一个月。在这项重复测量研究中，51名婴儿在4-16周龄的足月后参加了7次每两周一次的评估。在每次评估中，向婴儿提供相同的静态和动态配对比较刺激。视觉行为进行了评价，一个新引入的评分计划。我们的研究结果证实了建议的视觉发育层次结构，并清楚地证明了我们的评分方案记录在婴儿早期视觉注意力的发展变化的适用性。除了一般的个体发育过程中，我们还讨论了内部和个体间的差异，可能会影响单一的评估，并强调了可靠的评价发展变化的重复测量的重要性。
Theories of visual attention suggest a cascading development of subfunctions such as alertness, spatial orientation, attention to object features, and endogenous control. Here, we aimed to track infants' visual developmental steps from a primarily exogenously to more endogenously controlled processing style during their first months of life. In this repeated measures study, 51 infants participated in seven fortnightly assessments at postterm ages of 4-16 weeks. Infants were presented with the same set of static and dynamic paired comparison stimuli in each assessment. Visual behavior was evaluated by a newly introduced scoring scheme. Our results confirmed the suggested visual developmental hierarchy and clearly demonstrated the suitability of our scoring scheme for documenting developmental changes in visual attention during early infancy. Besides the general ontogenetic course of development, we also discuss intra- and interindividual differences which may affect single assessments, and highlight the importance of repeated measurements for reliable evaluation of developmental changes.
