Saccade latency. Eye position was sampled at 1 kHz using a scleral search coil. Saccade latency was determined using software custom-written with MATLAB (MathWorks). The saccade latency was measured from the object onset to the saccade onset.

Sequential saccade choice task. The main question of this task was whether a saccade followed by gaze occurred in response to the onset of an object. Saccade detection was triggered when the eye position left a central window (10° square) within 400 ms of object onset, whereas a no-saccade was registered when the eye position stayed within the central window. A saccade response was judged as the acceptance of the object if the eye position stayed within the peripheral window (13° square around the object) for 400 ms, which was followed by an outcome (reward or no reward). Otherwise, the behavior was judged as the rejection of the object, as explained in the “Behavioral procedures” section. The saccade rate (%) was calculated by (the number of trials in saccade to object)/(the total number of trials) × 100 (Figs. 2B and 3C and fig. S3).

Simultaneous saccade choice task. This task examined which object was chosen by the first saccade after two objects (one good and one bad) appeared simultaneously at different positions. The choice rate of bad object (%) was calculated by (the number of trials in first saccade to bad object)/(the total number of trials) × 100 (Fig. 4B and fig. S4).
