Reading and math are two subjects where accurate perception and understanding of spatial relationships are very important. The importance of being able to perceive objects in relation to other objects is often seen in math problems. The only cues to such math problems are the spacing and order between the symbols. These activities presuppose an ability and understanding of spatial relationships. This is the ability to differentiate objects based on their individual characteristics.
Visual discrimination is vital in the recognition of common objects and symbols.
Visual discrimination also refers to the ability to recognize an object as distinct from its surrounding environment. In terms of reading and mathematics, visual discrimination difficulties can interfere with the ability to accurately identify symbols, gain information from pictures, charts, or graphs, or be able to use visually presented material in a productive way. The ability to recognize distinct shapes from their background, such as objects in a picture, or letters on a chalkboard, is largely a function of visual discrimination. Visual closure Visual closure is often considered to be a function of visual discrimination. This is the ability to identify or recognize a symbol or object when the entire object is not visible.
