 Abstractly Related and Spatially Simultaneous Auditory-Visual Objects
While there is a large amount of visual bias in situations when discrepancies between visual and auditory spatial location occur, (Welch and Warren 1980) the correlation of cues from each modality may serve to encourage and reinforce the perception of intended abstract relationships between auditory and visual objects.

Changing the object’s look may fix this, so long as animation and other data doesn’t need to be changed with the new visual features.

The "hard wiring" of the basic visual perception processes, however, doesn't suggest that visual interpretation is an unsophisticated form of understanding any more than the concept of deep structure suggests that language learning is less complex or sophisticated.
Visual communication could also be considered primary because the viewer has to learn as well as manage more of the visual interpretative function independently.
We acquire visual competency through development and experience rather than training--in other words, for our basic nonverbal and visual communication skills we are largely self-taught and that includes such sophisticated skills as making sense of MTV, watching multiple television channels simultaneously, and negotiating freeways as we puzzle out a map.

 Blind Spots:
The relation of language and visual perception might be recognized as the essential ground for a visual sociology seeking to unify the senses rather than privileging vision over other sources of information about the world.
Visual sociologists are not the only ones with this problem.
Only because of this can the camera be considered neutral, a device for gathering visual data from which we then analyze (deduce) certain social patterns and meanings.

 New Theory Links Neurotoxins with Chronic Fatigue Syndrome, Lyme, MCS and Other Mystery Illnesses
In fact, experts suspect that many diseases involve deficits in visual perception, but there's little research relating toxic exposures to differences in visual function before diagnosing disease.
But unlike the brain, he points out, the visual system has few functional outputs (pattern and motion detection, or color discrimination, for example) and we can easily measure them.
"I realized that this meant there were different processes in the eye and brain for detecting different aspects of a visual pattern, and I wanted to understand how they worked," he said.

 AOJ 49: 173-177 "An Ophthalmologist's Approach to Children with Visual Perception and Learning Differences"
The science of learning, including auditory and visual perception, is truly a hybrid of these two disciplines.
Reading requires the centers in the brain concerned with vision, language and memory to integrate and efficiently coordinate the complex series of tasks required to interpret the written symbols on a page and extract meaning from them.3 Auditory processing is mediated similarly to visual processing.4
Although our pediatric, neurology, psychiatry and psychology colleagues have traditionally diagnosed and treated children with learning differences, the fact remains that ophthalmologists are often the physicians initially consulted and we should at least know the "language" of the science of learning.

 Visual perception - Wikipedia, the free encyclopedia
Visual perception is one of the senses, consisting of the ability to detect light and interpret (see) it as the perception known as eyesight, sight or naked eye vision.
The eye's retina performs the first stages of visual perception processing, with the remaining stages of visual perception occurring in the optic nerve, the lateral geniculate nucleus, and the visual cortex of the brain.
Models based on this idea have been used to describe various visual subsystems, such as the perception of motion or the perception of depth.

 Diana Mertz Hsieh: Representationalism and Perceptual Error
On the contrary, Berkeley contends that since the objects of direct perception can only be ideas and since these ideas exist only in the mind, it makes no sense to say that objects exist outside of the mind.
Locke holds the former (that ideas are the objects of direct perception) because physical objects are not in the mind, only ideas are.
In opposition to representationalism, both (direct) realism and idealism agree that perception is direct and unmediated, despite their disagreements about what the object of perception is. (Dancy, 145) In any form of direct perception, no correspondence relationship is possible, since there is only one object of perception.

 Studies in Visual Perception, II.
To test this, we can ask whether swirl perception is easily disrupted by insertion of a small delay between the presentation of its first and second essential elements (as is typical for 'early' visual processes), or resistant to such disruption.
We conjecture that the dividing line between these two families of visual modules comes with the perception of visual edges, so that the 'early' mechanisms could also be characterized as 'edge independent' and the 'late' mechanisms as 'edge dependent'.
This percept always appears when an edge-derived perception of the depth inside a rectangle finds nothing in the appropriate region to which a suitable depth can be ascribed, and when the ascribed surface fit to a boundary like the rectangle cannot be continued amodally behind something which seems to hide a portion of it.

 Minding the gap: visual perception and cinematic gap filling.(Critical Essay) - Style - HighBeam Research
Visual reorganization works by our being able to retrieve images from memory, images that may not have been classified and categorized at the time of perception, but are being determined at the time of this later cognitive operation, the one of gap filling.
But because visual perception and cognition operate differently from language perception and cognition, the existing models are unable to address the effects of visual data on film comprehension.
Although it is clear that the operations of visual perception and cognition are problematic for van den Broek's p ropositional sets, it is not impossible to articulate images into causal sets, but neither is it as easy and automatic as van den Broek suggests it is for reading.

 Touch can change visual slant perception - Nature Neuroscience
The observed adaptation could theoretically occur in visual perception, in proprioception of body parts or in the translation from visual to motor coordinates.
These visual−haptic studies sought concurrent perceptual effects, but we were primarily concerned with persistent effects of haptic feedback on visual perception.
Specifically, when subjects are given haptic stimulation consistent with the texture-specified slant of a visual stimulus, their subsequent visual percepts are closer to the texture slant than they were before training.

 A Moorean Response to Brain-in-a-Vat Scepticism
Now, it seems that we should characterize visual perception in this way – at least in part ‘from the outside’ – if we want to distinguish visual perception from other methods that we do not count as visual perception, for example, Ray’s belief-forming method.
This allows us to say, then, as perhaps we should, that the method of visual perception includes
the lenses of the eyes focussing … light on the retinas, where a pattern of retinal cell stimulation occurs that sends electro-chemical impulses along the optic nerve to the visual cortex, where a pattern of brain cell stimulation occurs with the upshot that the subject has a visual experience.

 2001proposal
The strongest correlations between neural activity and perception were observed in the visual areas of the temporal lobe.
Striking was the great number of neurons in the early visual areas that remained active during the perceptual suppression of the stimulus, a finding suggesting that conscious visual perception may be mediated by only a subset of the cells exhibiting stimulus selective responses.
Perception-related modulations of neural activity were found to occur to different extents in different cortical visual areas.

 FamilyFun: Learning Disabilities: Visual Perception Disorders
Visual perception disorders are the most subtle--and the most difficult to recognize--of the four major types of learning disabilities.
Children with visual perception problems may have related difficulties that include a poor sense of direction, problems judging speed and distance, and difficulties with planning and organizational skills.
While visual perception disabilities can make school very difficult for children, much can be done to help them compensate for the problem.

 SOLVING THE "REAL" MYSTERIES OF VISUAL PERCEPTION:
Even though classic visual phenomena like the illusions and effects displayed in science museums and the specific domains currently discussed by visual scientists, such as colour vision, stereopsis, movement perception, contrast sensitivity, etc., are important and interesting, they are in a way just the tip of the iceberg in the task of understanding vision.
The idea of visual perception involving component extraction is also compatible with Ivo Kohler's (1951) findings, according to which after training with spectacles that transform the visual world in various ways (inverting, reflecting), subjects re-establish normal upright perception in a fragmentary way, with aspects of the environment being corrected, and others not.

 INTRODUCTION
The same oculomotor activity pattern was observed during the visual perception task and during the imagery task.
If the oculomotor information is encoded together with the visual information in the visual perception task, then in the imagery task, the same pattern of oculomotor activity should be present.
Hebb proposed an inherent oculomotor component in visual perception and visual imagery, claiming that if imagery is the reinstatement of a perceptual process, then this process should include eye movements.
