动物必须有选择地注意相关的刺激，避免被不重要的刺激分心。跳蛛（跳蛛科）通过协调具有不同能力的眼睛来做到这一点。物体由一对高敏锐度的主眼检查，其狭窄的视野由视网膜运动补偿。主眼与运动敏感的前外侧眼（ALE）在视野中重叠，这将它们的目光引导到新的刺激。使用salicid-specific眼动仪，我们监测的注视方向的主要眼睛，因为他们审查了主要的刺激。然后，我们提出了一个分心刺激可见的ALE，并观察是否主眼反射性地转移他们的目光，它或是否这种反应是灵活的。蜘蛛是否将目光转向干扰物取决于主要刺激和干扰物刺激的性质。这种灵活性表明，高阶处理发生在主眼注意力的管理中。
Animals must selectively attend to relevant stimuli and avoid being distracted by unimportant stimuli. Jumping spiders (Salticidae) do this by coordinating eyes with different capabilities. Objects are examined by a pair of high-acuity principal eyes, whose narrow field of view is compensated for by retinal movements. The principal eyes overlap in field of view with motion-sensitive anterior-lateral eyes (ALEs), which direct their gaze to new stimuli. Using a salticid-specific eyetracker, we monitored the gaze direction of the principal eyes as they examined a primary stimulus. We then presented a distractor stimulus visible only to the ALEs and observed whether the principal eyes reflexively shifted their gaze to it or whether this response was flexible. Whether spiders redirected their gaze to the distractor depended on properties of both the primary and distractor stimuli. This flexibility suggests that higher-order processing occurs in the management of the attention of the principal eyes.
