Information in the parafovea can influence the processing of a scene.

Only later was it centered in the parafovea.

The fovea is surrounded by the parafovea belt, and the perifovea outer region.

Critical stimulus in parafovea: noncritical and critical trial display.

The parafovea has an outer diameter of 2.5 mm representing 8 of the field of vision.

Information present in the parafovea can interact with information present in the fovea.

Subtle vascular changes in the retina resembling telangiectasia (spider veins) in the parafovea circulation.

A ring-shaped region surrounding the fovea, known as the parafovea, is sometimes taken to represent an intermediate form of vision called paracentral vision.

Parafovea or the parafoveal belt is a region in the retina that circumscribes the fovea and is part of the macula lutea.

The macula is subdivided into the umbo, foveola, foveal avascular zone (FAZ), fovea, parafovea, and perifovea areas.

BY mechanism shows a less steep decline in contour integration across the parafovea than RG mechanism, whereas ACH mechanism shows no loss.

In contrast, when the critical stimulus was presented at fixation and the cross appeared in the parafovea, it was the location of the cross that varied from trial to trial.

Below the pit the other retina layers are displaced, before building up along the foveal slope until the rim of the fovea or parafovea which is the thickest portion of the retina.

Given the distribution of receptors across the retina, and corresponding cortical neural distributions, global letters may simply be more visible in the parafovea than local letters in this view (Kinchla & Wolfe, 1979).

An effect of parafoveal preview has also been found for emotional scenes presented in the parafovea, with people more likely shift their fixation point on emotional stimuli than neutral stimuli, when both options are presented parafoveally.

The benefit the parafoveal preview has is also mediated by how common the word in the parafovea is, with less common words providing less of a reduction in fixation duration when they reach foveal fixation.

In categorization tasks of natural scenes information from the parafovea can be used to determine the gist of a scene well enough for a categorization judgement, though with reduced sensitivity and speed in comparison to foveal vision.

Another possibility, however, is that the limit on the visibility of local letter changes in the parafovea is not only a low-level one, as might be expected on the basis of the decreasing spatial resolution that accompanies increasing visual eccentricity.

In one of these experiments it was possible, by presenting a small black square in each of the four quadrants of the cross, to create as much IB for a critical stimulus located in the parafovea as for the same stimulus at fixation.

Studies have shown that people can tell the difference in the letters of a word in the fovea and near-parafovea (the part of the parafovea closest to the fovea), but not in the outer edges of the parafovea.

As the clarity of information in the parafovea is not as great as in the fovea, the SWIFT model of eye movements in reading, while allowing for parallel processing, accounts for this difference by assigning the parafoveal less processing power the further away it is from the foveal fixation.
