The parietal cortex is the main brain area involved in this visual-spatial activity. 

In everyday life, you need to consider objects’ size, shape, and angles to judge their distance from you. Judging distance and depth (e.g., how far is it from my hand to that cup?), velocity (speed) (e.g., how fast is that car moving toward me?), and size (e.g., will these leftovers fit in that container?) are questions that also rely on skills practiced in this exercise.

You can modify:

• The number of stimuli (5, 10, 15, 20, 25, 30, 40, or 50)
• The time of letter display on the screen (1500, 800, 600, 400, or 200 milliseconds)
• The time of cross display on the screen (1500, 800, 600, 400, or 200 milliseconds)
• The time of circle display on the screen (1500, 800, 600, 400, or 200 milliseconds)
• The time lapse between stimuli (0, 100, 200, 400, 800, or 1000 milliseconds)
• The distance between stimuli (very easy, easy, medium, hard, or very hard)
• The disrupting element (without or with)
