Decision making has been regarded as the last stage before action in the human information processing, certainly subsequent to sensory sampling and perceptual integration. Previous studies showed that gaze supports the brain in making a decision, especially in preference tasks. Specifically, it has been shown that in two alternative forced-choice tasks subjects exhibit significant tendency to look increasingly towards the chosen event. This behavior is called “gaze cascade effect”.
We study the parameters underlying the Decision Making by means of stylized decisional frameworks such as those devised by economists.
