The Cognitive Bias Apparatus uses association-based learning to investigate the influence of cognitive bias on decision making.
The apparatus consists of a two-chamber set-up with a tunnel connecting the chambers. One of the chambers acts as the start box, while the other as the goal box. The goal box consists of two foraging bowls, that have distinct color and odors (scented sand), placed in either corner of the back wall.
The task relies on the subject learning the association between the grade of sandpaper placed in the connecting tunnel with the high reward foraging bowl.
