A reduced ability to make sense of information taken in through the eyes is called visual perception problems, visual perception deficits, or visual processing disorder. These are referred to as functional vision problems.Įven if the visual system is physically intact and works efficiently, the brain must interpret visual information correctly. Other vision difficulties are caused by problems that affect the efficiency of the visual system. These may be present at birth or caused by injury or illness and are referred to as structural vision problems.
Some are caused by physical abnormalities of the eyes or their related structures. There are many different types of vision problems that may occur in children. For example, they struggled to remember the locations of items in a spatial grid. The researchers found that children with dyscalculia showed poor visuospatial memory performance. Szűcs and team (2013) set out to compare various potential theories of dyscalculia in more than a thousand 9-year-old children. Some studies have reported visual perception deficits as components of dyslexia ( Goswami et al., 2010 Stefanics et al., 2011 Vidyasagar & Pammer, 2010 Zhao et al., 2014), while others have associated visual perception deficits with dyscalculia ( Sigmundsson et al., 2010 Zhou & Cheng, 2015). Recent studies have linked visual perception to dyslexia and dyscalculia. Children with visual perception problems have trouble recognizing, remembering, and organizing visual images as needed to understand written and pictorial symbols, which can interfere with many aspects of daily living, most notably learning to read, write, and do math. Visual perception is a highly critical component of a child’s learning. It involves the ability to mentally manipulate visual information as needed to solve problems and to take action in response to environmental demands. Kurtz (2006) defines visual perception as the cognitive component of interpreting visual stimuli. Visual perception and visual processing are often used interchangeably and refer to the brain’s ability to understand what one sees. In other words, perception represents our apprehension of a present situation in terms of our past experiences, or, as stated by the philosopher Immanuel Kant (1724-1804): “We see things not as they are but as we are.” What is visual perception? Thus, a lack of experience may cause people to misinterpret what they have seen.
For example, an illiterate person would not be able to group the lines in the image on the right in the same way and complete the missing lines as you who can read them.
Perceptual ability, therefore, heavily depends upon the amount of perceptual practice and experience a person has already enjoyed. Interpretation of sensory phenomena can only be made based on past experiences of the same, similar, or related phenomena.
