CVI Visual Behaviors: Form Accessibility

CVI, a brain-based visual impairment, is the leading cause of childhood blindness. Individuals with CVI tend to display visual behaviors. Form Accessibility is one of these CVI behaviors that needs to be assessed on an ongoing basis.
What is Form Accessibility?
-Individuals with CVI have varying abilities to access objects or learning materials in different forms. Form refers to types of visual materials—real objects, three-dimensional (3D), two-dimensional (2D), abstract or symbolic.
-This assessment area evaluates the most accessible media form based on the individual’s visual abilities and includes evaluation of the visual accessibility of multicolored materials versus solid colored materials and attention to and recognition of 3D and 2D materials.
-Some individuals with CVI can visually attend to and recognize 3D materials but struggle with interpreting flat, 2D materials.
-Oftentimes, realistic 3D and 2D materials can be more visually accessible than cartoon-like or symbolic materials.
-When it comes to CVI, it’s important to know that looking is not understanding.

At Perkins, we synthesize literature and current research to better understand and expand upon our understanding of CVI, so all children with CVI are able to be fully understood.
