A subject's vernier (IPA: / ˈ v ɜːr n ɪər /) acuity is the smallest visible offset between the stimuli that can be detected. Because the disalignments are often much smaller than the diameter and spacing of retinal receptors, vernier acuity requires neural processing and "pooling" to detect it. Because vernier acuity exceeds acuity by far ...
PHP takes advantage of visual hyperacuity, also known as vernier acuity—the ability to identify the misalignment of visual objects. Visual hyperacuity is at least 10 times more sensitive than visual acuity, the ability to separate between distinct objects. [4]
The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. So for a vernier with a constant of 0.1, each mark on the vernier is spaced 9/10 of those on the main scale.
Ewald Hering's model, published 1899, of how a Vernier acuity stimulus is coded by a receptor array. Receptors marked c signal a different position code along the horizontal direction from either the position a code or the position b code. [1] The sharpness of our senses is defined by the finest detail we can discriminate.

A medical procedure is a course of action intended to achieve a result in the delivery of healthcare. A medical procedure with the intention of determining, measuring, or diagnosing a patient condition or parameter is also called a medical test .
At the San Diego Naval Medical Center, the eight-week moral injury/moral repair program begins with time devoted simply to allowing patients to feel comfortable and safe in a small group. Eventually, each is asked to relate his or her story, often a raw, emotional experience for those reluctant to acknowledge the source of their pain.
Like experimental procedures, other attempts to apply perceptual learning methods to basic and complex skills use training situations in which the learner receives many short classification trials. Tallal, Merzenich and their colleagues have successfully adapted auditory discrimination paradigms to address speech and language difficulties.
