Cai, D.J., Jiang, Y.V., Makovski, T., Mednick, S.C. (2009). These can lead to the patient losing their spatial memory, and/or their visual memory for specific things. Dyslexia
As the subject encodes the visual patterns researchers are able to directly view the activation of areas involved in visual memory encoding[8]. As we age performance in regards to spatial configurations deteriorates. Damage to the occipital lobes can permanently damage visual perception[5]. However there is debate over whether this is the only reason for reading disabilities, scotopic sensitivity syndrome, deficits in verbal memory and orthographic knowledge are other proposed factors[24]. Often, these people suffer from certain mental disorders, or they may be identified as savants. Retrieved from. That is, the person must be capable of making a vivid visual image in his mind of the stimulus, such as a word, and once that stimulus is removed, to be able to visualize or recall this image without help. The transient system is responsible for controlling eye movements, and processing the larger visual environment around us.
Fu, X., Wang, B. In a task to store and combine two different spatial configurations to form a novel one young people out-performed the elderly. In the second stage participants are asked to copy each of the 10 card designs while the cards are in view[7]. [19] In a study conducted to measure whether visual memory in older adults with age-related visual decline was caused by memory performance or visual functioning, the following were examined: relationships among age, visual activity, and visual and verbal memory in 89 community dwelling volunteers aged 60-87 years. When a person's brain takes in visual information, it is not stored as a single image or set of images.
Bhatt, E., Cattaneo, Z., Merabet, L.B., Pece, A., Vecchi, T. (2008).
[17], Brain damage is another factor that has been found to have an effect on visual memory. The data collected from neuroimaging studies gives researchers the ability to visualize which brain regions are activated in specific cognitive visual memory tasks. A more controversial proposal, however, is that VSTM can be subdivided into two separate storage subsystems, one for spatial information and another for object identity information. A classic test of spatial memory is the Corsi block-tapping task, where an instructor taps a series of blocks in a random order and the participant attempts to imitate them. English thesaurus is mainly derived from The Integral Dictionary (TID). [21] Vision also has an effect on performance. Neuroimaging studies focus on the neural networks involved in visual memory using methods designed to activate brain areas involved in encoding, storage, and recall. Perfect memory of this type is known as photographic or eidetic memory.
Her parents had been told by more than one professional that Maddie would probably never read...

(2007). The subjects resting brain activation level is first determined in order to form a control or 'baseline' to measure from[8]. Iconic memory is responsible for visual priming, because it works very quickly and unconsciously. (1995). Object memory involves processing features of an object or material such as texture, color, size, and orientation.
This test has proven its sensitivity to reading disabilities, nonverbal learning disabilities, traumatic brain injury, attention-deficit disorder, alzheimer's, and other forms of dementia[6].
They also represent images on their visuo-spatial sketchpad in almost life-like vividness. Retrieved from.
During testing participants are presented with 10 cards for 10 seconds with unique designs on each[7]. The findings were that the effect of vision was not specific to visual memory. The sustained system is responsible for fine detail such as word and letter recognition and is very important in encoding words in their correct order.
The dorsal stream pathway is also involved in the guidance of movements (e.g., reaching for an object in space), and is therefore implicated in the analysis of the movement of objects in addition to their spatial locations.
