Despite the recognition of AHP often this method is censured to sufficiently handle its failure for the imprecision and latent uncertainty associated with the grading of the decision maker's perception of exact values [ 29].
Current evidence for respiratory allergies also suggests, that the protective effect of farm living is associated mainly with livestock exposure, because the animals mediate the microbial exposure in these environments, but the exact mechanisms behind this perception is still debated [ 54, 55].
As gaze modulated pointing uses different sensors to track and detect user behaviours, its performance relies on the user's perception on the exact spatial mapping between the virtual space and the physical space.
Even though visualizing the square, the inner square and then visualizing the corner triangles folding over is constrained by the results of earlier perceptual experience of scenes with relevant similarities, we cannot draw from it reliable information about exact equality of areas, because perception itself is not reliable about exact equalities (or exact proportions) of continuous magnitudes.
However, the exact mechanisms underlying this phantom perception are still unknown.
In the French psychiatry literature of the late 19th and early 20th centuries, the typical autoscopic hallucination was also labelled as "mirror hallucination" [ 6- 10] and consists of a visual perception of an exact mirror image of oneself, occasionally only one's face or trunk is perceived.
Despite extensive research on ROS signalling, the exact components mediating ROS signalling, ROS sensing, and perception in particular are still unknown.
While the experiment above suggests some involvement of attention in the forward transition, the exact role it plays in the perception of AV synchrony remains unclear.
Preliminary data collected in a simple test of auditory perceptual streaming (see Text S1) also support a link between continuity perception and streaming; more exact perceptual characterizations will be required to rigorously test these ideas in future experiments.
