Answer:
figure/ground
Step-by-step explanation:
Figure/ground is the organization matter that is used in the Gestalt psychological as one of the main principles. It is the way the perceptional field is organized and understood. The figure is what is standing in front (mostly black) and the ground refers to the background (usually white), or what is behind the figure.
In a non-visual matter of psychological reading, these themes are represented as subject and background, as well as the positive and negative space. What is positive space and figure is what we are focused on, while the ground or negative space is what we can easily oversee in the background.
