The effect of saccadic eye movements on threshold perception is investigated theoretically. The proposed model considers eye movements by taking into account the shifting of the stimulus pattern on the retina during the occurrence of an eye movement. Saccades are characterized by high velocity and short duration. These motions cause overshoots in the response of linear filters to certain stimulus patterns. Therefore, the model predicts facilitation effects of saccades in the perception of low spatial frequency patterns and patterns flickering with high temporal frequencies. These results agree with experimentally obtained data presented in a subsequent paper. A simple approach is formulated which approximates the complex shifting function of a saccade by a switching of the pattern.
本文从理论上研究了眼球跳动对阈值感知的影响。所提出的模型通过考虑眼球运动期间视网膜上刺激模式的移动来考量眼球运动。扫视的特点是速度快、持续时间短。这些运动会导致线性滤波器对某些刺激模式的响应出现超调。因此，该模型预测扫视在低空间频率模式和高时间频率闪烁模式的感知中具有促进作用。这些结果与后续论文中给出的实验数据一致。本文提出了一种简单的方法，通过模式切换来近似扫视的复杂移动函数。
