Left: participants prefer cardinals and upward directions without receiving rewards. Center: after titrating rewards throughout the experiment, downward and cardinal directions provide less reward, i.e., participants are willing to saccade there even though they gain little in comparison. Right: This titration of rewards offsets the internal saccade costs, leading to uniform preference across directions
Responses on an online Stroop task. A bot achieved average RT and accuracy that is in line with recent papers on the Stroop task.
data saturation for gaze heatmaps. Initially, any additional participant will bring the total NSS or AUC as measures for heatmap similarity a lot closer to the full sample. However, the returns diminish increasingly at higher n.

more intense pupil dilations to stimulation at more sensitive body locations
saccade costs (measured with pupil size) against saccade preferences. Affordable saccades are preferred.
