Numerosity adaptation effect

 

The numerosity adaptation effect is a finding that human brains quickly perceive the number of items in a visual display, which influences the perception of the number of items in later displays.

Quote

Evidence exists for a nonverbal capacity for the apprehension of number, in humans [1] (including infants [2, 3]) and in other primates [4, 5, 6]. Here, we show that perceived numerosity is susceptible to adaptation, like primary visual properties of a scene, such as color, contrast, size, and speed. (Burr & Ross, 2008)
