Chosen concept: the just noticeable difference.
Definition: The just noticeable difference is when there are two or more things that look extremely similar but are different by just a very small aspect. It's when we don't perceive something because of what we expect from perceiving, visually, something very similar to it.
Two examples illustrating the just noticeable difference:
a.) Personal experience-I remember when I was child I would play games in coloring books and school magazines where I would have to look at two images and find differences between them, circling the small things I found. The reason it can be so difficult is that when looking at one image you immediately perceive its general appearance, so when you look at the other you become unsure whether something very small and particular was in the first image. This demonstrates that prior visual perception has affected your perception of the other image because your brain notices that it is almost the same at first glance, and glides over the smaller details.
b.) Related to an area of knowledge-This ties into the area of knowledge called the arts. For example, an artist sometimes takes advantage of this aspect of the human brain and can base a painting, for example, off of it. If said artist paints two pieces of art that look the same at first, but he actually painted it in slightly lighter hues or moved the main focus a little to the right, it can be considered an art display to have the two paintings next to each other, as one may have to really study the pictures to find the differences, and may even find they prefer one to the other due to the just noticeable difference.
