在早期视觉处理过程中，眼睛可以捕捉到环境中显着的视觉信息。显着刺激是否以纯粹自动、自下而上的方式吸引眼球，或者捕获是否取决于任务要求，仍然存在争议。在第一个实验中，我们操纵了显着起始干扰因素的相关性。起始干扰项可能与目标相似或不同。错误扫视潜伏期分布表明，在早期，动眼神经捕获是纯粹自下而上驱动的，与干扰物的相似性无关。后来，自上而下的信息变得可用，导致了偶然的捕获。在第二个实验中，我们操纵了目标位置的显着性信息。显着的起始刺激可以出现在目标位置或非目标位置。错误和正确扫视的延迟分布与第一个实验中观察到的时间过程相似。最初，分布重叠，但后来与任务相关的信息减慢了动眼系统的速度。目前的研究结果揭示了动眼行为中自下而上和自上而下过程之间的相互作用。我们的结论是，显着事件的任务相关性对于吸引眼球的发生并不重要。此外，与任务相关的信息可以与显着性信息结合以启动眼跳，但只是在稍后的时间。
During early visual processing the eyes can be captured by salient visual information in the environment. Whether a salient stimulus captures the eyes in a purely automatic, bottom-up fashion or whether capture is contingent on task demands is still under debate. In the first experiment, we manipulated the relevance of a salient onset distractor. The onset distractor could either be similar or dissimilar to the target. Error saccade latency distributions showed that early in time, oculomotor capture was driven purely bottom-up irrespective of distractor similarity. Later in time, top-down information became available resulting in contingent capture. In the second experiment, we manipulated the saliency information at the target location. A salient onset stimulus could be presented either at the target or at a non-target location. The latency distributions of error and correct saccades had a similar time-course as those observed in the first experiment. Initially, the distributions overlapped but later in time task-relevant information decelerated the oculomotor system. The present findings reveal the interaction between bottom-up and top-down processes in oculomotor behavior. We conclude that the task relevance of a salient event is not crucial for capture of the eyes to occur. Moreover, task-relevant information may integrate with saliency information to initiate saccades, but only later in time.
