Closure.

Explanation:

In the artistic context, closure is called the mental process by means of which the viewer of a work of art in which there are no limits defined by clear and detailed lines seeks to give a closure to said figure, trying to delimit it in order to understand its spatial location within the work. In turn, many artists play with this situation, leaving spaces between different figures, looking for the viewer to try to delimit them through this mental process.
