“visual perception: The ability to recognize and interpret visual information provided to the brain. Difficulties in visual perception are separate from and unrelated to impairment in the visual system that may diminish visual acuity or result in visual impairment or blindness. Visual perception involves the determination and discrimination of spatial information, as well as performance on tasks such as the discrimination of letters and words, geometric designs, and pictures.
Visual perception is an essential component of learning, especially in regard to reading development and to acquiring classroom information. Difficulties with visual perception may significantly affect and individuals ability to discriminate letters and words, and to work with mathematical information.”
