We investigated developmental differences in oculomotor control between 10-year-old children and adults using a central interference task. In this task, the colour of a fixation point instructed participants to saccade either to the left or to the right. These saccade directions were either congruent or incongruent with two types of distractor cue: either the direction of eye gaze of a centrally presented schematic face, or the direction of arrows. Children had greater difficulties inhibiting the distractor cues than did adults, which revealed itself in longer saccade latencies for saccades that were incongruent with the distractor cues as well as more errors on these incongruent trials than on congruent trials. Counter to our prediction, in terms of saccade latencies, both children and adults had greater difficulties inhibiting the arrow than the eye gaze distractors.
我们使用一项中央干扰任务，研究了10岁儿童与成年人在眼动控制方面的发育差异。在这项任务中，注视点的颜色指示参与者向左或向右进行扫视。这些扫视方向与两种类型的干扰线索一致或不一致：要么是中央呈现的示意性面孔的目光方向，要么是箭头的方向。与成年人相比，儿童在抑制干扰线索方面有更大的困难，这表现为与干扰线索不一致的扫视的扫视潜伏期更长，以及在这些不一致的试验中比在一致的试验中有更多的错误。与我们的预测相反，就扫视潜伏期而言，儿童和成年人在抑制箭头干扰方面比抑制目光干扰有更大的困难。
