Clousure

Closure: explains how humans fill in visual gaps of an image to make it complete.

for example if you see look up in the sky, and see a lot of stars, you will still be able to locate the big dipper even though you only know half of how it looks.

Continuity: states the people tend to group forms in line and patterns as being similar
for example in the following picture with the geese, we perceive the formation to be a big "V"

Similarity: objects that are similar in appearance are perceived to be identical.

for example, in the picture to the left, most people see a horizontal grouping of pink triangles and blue windmill shape.

Proximity: objects that are close together are more likely perceived as being in the same group

the image to the right, shows people that are close together, so we precise these people as being in the same group.
