Some theorists believe that decisions follow from a series of discrete evidence accrual events, wherein evidence is gradually gathered in support of each possible alternative response option. This model simulates an eye saccading around a colour display in an attempt to determine which colour is represented in the display most often.
Feel free to play with this. If the eye is moving too quickly, adjust the speed slider located over the stimulus and/or reduce the saccade size.
