Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination [ 1 ] : 632 [ 2 ] : 71 and is assumed to reflect how finely innervated an area of skin is.
Spatial discrimination is another form of Two-point discrimination in which the practitioner tests for innervation of the skin with two blunt points of a compass (drawing tool). Just with like 2PD , the patient must be able to discriminate between the two applied points.
It can determine how short a distance between two impressions on the skin can be distinguished. To differentiate between two points and one point of equal area (the sum of the areas of the two points equals the area of the third point), Dr. Sidney Weinstein created the three-point esthesiometer.
Tactile discrimination is the ability to differentiate information received through the sense of touch. The texture discrimination task is a common task used in visual perception learning. Two-point discrimination is the ability to discern that two nearby objects touching the skin are distinct.
Discrimination testing is a technique employed in sensory analysis to determine whether there is a detectable difference among two or more products.
