Summary
Visual processing speed is not uniform across the visual field. This review explores how processing speed changes with eccentricity in low-level photopic vision, synthesizing psychophysical and neurophysiological findings.
Area of Science:
- Neuroscience
- Vision Science
- Psychophysics
Background:
- Human vision subjectively appears stable, yet is built from spatially and temporally inhomogeneous visual information.
- Spatial vision inhomogeneities are well-studied, but temporal dynamics, particularly processing speed variations, are less understood.
Purpose of the Study:
- To review and synthesize psychophysical and neurophysiological findings on how visual processing speed varies with eccentricity in low-level photopic vision.
- To identify areas of consensus and disagreement in current research on visual processing speed and eccentricity.
Main Methods:
- Non-systematic review of psychophysical and neurophysiological studies.
- Focus on low-level photopic vision.
- Analysis of how processing speed changes with visual field eccentricity.
Main Results:
- Processing speed in low-level photopic vision demonstrably varies across the visual field.
- Key findings from major investigations are examined, highlighting convergence and divergence.
- Specific patterns of speed variation with eccentricity are discussed.
Conclusions:
- Significant variations in visual processing speed exist across the visual field.
- Further research is needed to resolve outstanding questions regarding temporal dynamics in vision.
- Understanding these inhomogeneities is crucial for a complete model of visual perception.

Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
Parallel Processing
The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...
Visual System
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
Association Areas of the Cortex
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
