训练猴子将它们的注视方向从1点（注视点）改变到另一点（目标）。如果注视点在新目标出现的同时消失，则扫视反应时间（SRT）为200 ms的量级。如果注视点在新目标出现之前消失150-250 ms（没有可见刺激的间隙），则猴子在较短的反应时间aptx后进行规则的扫视。在差距情况下的动物进行扫视，其具有从新目标开始测量的不超过70-80 ms的反应时间（快速扫视）。E-扫视的反应时间的SD仅为±。如果差距< 180 ms，则在反应时间为140-160 ms的情况下进行越来越规则的扫视。随着间隙持续时间从140 ms减少到0，所有扫视的反应时间为140-160 ms。间隙持续时间从140 ms减少到0，所有扫视都是规则的，在1只动物中，几乎所有的E-扫视都变短并且在< 250 ms之后被校正，这取决于错误的大小：大的错误比小的错误被更快地校正。
Monkeys were trained to change their direction of gaze from 1 point (fixation point) to another (target). If the fixation point was extinguished at the same time when the new target occurred, the saccadic reaction times (SRT) were in the order of 200 ms. If the fixation point disappeared 150-250 ms before the new target occurred (gap with no visible stimulus), monkeys made regular saccades after shorter reaction times of .apprx. 140 ms. Animals in the gap situation made saccades that had reaction times of no more than 70-80 ms measured from the onset of the new target (Express-Saccades). The reaction times of the E-saccades have SD of only .+-. 3 ms. E-saccades occurred with a frequency of up to 80% for gaps of 200-240 ms. If the gap was < 180 ms, increasingly more regular saccades were made with reaction times of 140-160 ms. With gap duration decreasing from 140 ms to 0, all saccades were made with reaction times of 140-160 ms. With gap duration decreasing from 140 ms to 0, all saccades were regular, with SRT increasing linearly to > 200 ms. In 1 animal almost all E-saccades fell short and were corrected after < 250 ms, depending on the size of the error: large errors were corrected faster than small ones.
