Stimulus configuration and fixation statistics. (A) Example stimulus arrangement in the foraging task, with five potential targets (‘T’) and five distractors (‘+’). The animal initiated the task by directing his gaze towards the fixation spot that appeared on one side of the screen. Following a delay ranging from 450 to 700 ms, an array of stimuli emerged, with five potential targets (‘T’) and five distractors (‘+’). Notably, one of these ‘T’ symbols was associated with a reward. To obtain the reward, the animal had to successfully fixate on the reward-associated ‘T’ within a 1.5° window and maintain the fixation for at least 500 ms. This action had to be completed within an 8 s timeframe from the start of the trial. (B) Histogram of the duration of eye fixations on ‘T’s (blue) and ‘+’s (red), excluding the rewarding fixation.
