Nonverbal learning disorder (NVLD or NLD) is a proposed neurodevelopmental disorder characterized by core deficits in nonverbal skills, especially visual-spatial processing. People with this condition have normal or advanced verbal intelligence and significantly lower nonverbal intelligence. [ 3 ]
Visuospatial dysgnosia, along with Balint's syndrome, has been connected with Alzheimer's disease as a possible early sign of the disease. [2] Generally, the first symptom of Alzheimer's onset is loss of memory, but visual or visuospatial dysfunction is the presenting symptom in some cases [3] and is common later in the disease course. [4]
A region of space within the visual field is selected for attention and the information within this region then receives further processing. Research shows that when spatial attention is evoked, an observer is typically faster and more accurate at detecting a target that appears in an expected location compared to an unexpected location.

Nonverbal learning disorder (NLD or NVLD), a neurodevelopmental disorder thought to be linked to white matter in the right hemisphere of the brain and generally considered to include (a) low visuospatial intelligence; (b) discrepancy between verbal and visuospatial intelligence; (c) visuoconstructive and fine-motor coordination skills; (d ...
Simultanagnosia (or simultagnosia) is a rare neurological disorder characterized by the inability of an individual to visually perceive more than a single object at a time. . This type of visual attention problem is one of three major components (the others being optic ataxia and optic apraxia) of Bálint's syndrome, an uncommon and incompletely understood variety of severe neuropsychological ...
Visual thinking, also called visual or spatial learning or picture thinking, is the phenomenon of thinking through visual processing. [1] Visual thinking has been described as seeing words as a series of pictures. [2] [3] It is common in approximately 60–65% of the general population. [1] "Real picture thinkers", those who use visual thinking ...
Visuospatial processing refers to the "ability to perceive, analyze, synthesize, manipulate and transform visual patterns and images". [2] Visuospatial working memory (VSWM) is involved in recalling and manipulating images to remain oriented in space and keep track of the location of moving objects. [2]
Visual processing is a term that refers to the brain's ability to use and interpret visual information from the world. The process of converting light energy into a meaningful image is a complex process that is facilitated by numerous brain structures and higher level cognitive processes.
