Visual Perception


Visual perception is the total process responsible for the reception and understanding of what is seen.  Children with visual perception problems may have difficulty with letter reversals, learning the alphabet, recognizing words, and understanding basic math concepts.  Visual perception skills can be broken down into the following areas:

· Visual discrimination - the ability to distinguish similarities and differences between objects like letters (d, b) or shapes.
· Visual sequencing - the ability to determine or remember the order of symbols, words, or objects.
· Visual figure-ground - the ability to locate a single object within a complex background.
· Visual-motor processing - using feedback from the eyes to coordinate movement of other parts of the body.
· Visual memory - the ability to recall what is seen.
· Visual closure - the ability to know what an object is when only parts of it are visible.
· Visual spatial relationships - (also known as visual spatial orientation) - understanding the position and relationship of objects to oneself and knowing right and left.
· Visual form constancy - the ability to mentally manipulate forms and visualize the resulting outcomes. This skill helps children distinguish differences in size, shape, and orientation. Children with poor form-constancy may frequently reverse letters and numbers.
