Infants judged at birth to be at risk for cerebral damage show at 2 to 4 months of age significant differences compared to normal controls with respect to visual behavior at presentation of geometric patterns: Children of the risk group discriminated less consistently between a striped pattern and a homogenous gray surface. Their average time of fixation is significantly longer, and they show increased variance within the test parameters. It was therefore concluded that parameters of visual fixation and discrimination could probably allow for more reliable prognoses for future cognitive development in an infant. A longitudinal study to test this hypothesis is already in execution.
出生时被判定有脑损伤风险的婴儿，在2至4个月大时，与正常对照组相比，在呈现几何图案时的视觉行为存在显著差异：风险组的儿童在条纹图案和均匀灰色表面之间的辨别一致性较低。他们的平均注视时间明显更长，并且在测试参数内表现出更大的差异。因此得出结论，视觉注视和辨别的参数可能有助于对婴儿未来的认知发展做出更可靠的预测。一项检验这一假设的纵向研究已经在进行中。
