在婴儿眼动追踪过程中，由于重复校准刺激和测试过程中的身体运动而引起的模糊是对测量质量的常见限制。在这里，我们系统地调查了使用EyeLink 1000 Plus的婴儿和成人的这些限制。我们比较了注视时间和分散的凝视点引起的刺激类似常用的校准动画。成人组在注视记录过程中还进行了身体运动，这些运动相当于婴儿在测试过程中自发产生的运动。在我们的研究结果中，婴儿对特定校准目标的偏好并不能预测该刺激引起的数据质量，但在其中心或具有全球分布复杂性的目标中表现出最强对比的目标导致了最高的准确性。我们从成人运动任务的注视测量受到运动类型以及目标出现在屏幕上的位置的不同影响。在计划婴儿眼动追踪实验时，应考虑到这些运动对测量的异质性影响。此外，为了提高数据质量，可以通过在精确的校准目标之间交替来促进婴儿对重复校准的耐受性。
During infant eye-tracking, fussiness caused by the repetition of calibration stimuli and body movements during testing are frequent constraints on measurement quality. Here, we systematically investigated these constraints with infants and adults using EyeLink 1000 Plus. We compared looking time and dispersion of gaze points elicited by stimuli resembling commonly used calibration animations. The adult group additionally performed body movements during gaze recording that were equivalent to movements infants spontaneously produce during testing. In our results, infants' preference for a particular calibration target did not predict data quality elicited by that stimulus, but targets exhibiting the strongest contrasts in their center or targets with globally distributed complexity resulted in the highest accuracy. Our gaze measures from the adult movement tasks were differentially affected by the type of movement as well as the location where the target appeared on the screen. These heterogeneous effects of movement on measures should be taken into account when planning infant eye-tracking experiments. Additionally, to improve data quality, infants' tolerance for repeated calibrations can be facilitated by alternating between precise calibration targets.
