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. In clinical settings, two-point discrimination ...
Tactile discrimination is the ability to differentiate information through the sense of touch. The somatosensory system is the nervous system pathway that is responsible for this essential survival ability used in adaptation. [1] There are various types of tactile discrimination. One of the most well known and most researched is two-point ...
An esthesiometer (British spelling aesthesiometer) is a device for measuring the tactile sensitivity of the skin (or mouth, or eye, etc.). The measure of the degree of tactile sensitivity is called aesthesiometry. The device was invented by Edward Henry Sieveking. There are different types of aesthesiometers depending on their particular function.
Graphesthesia can be considered as a type of synthetic sensation as it involves a complex interaction between three neural components i.e. Tactile sensation, two point discrimination and cortical component that stores infirmation about the symbol/letter that is being traced in the skin and was learned through some previous experience.
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1] The main functions of the somatosensory system are the perception of external ...
e. Discrimination is the process of making unfair or prejudicial distinctions between people based on the groups, classes, or other categories to which they belong or are perceived to belong, [1] such as race, gender, age, species, religion, physical attractiveness or sexual orientation. [2] Discrimination typically leads to groups being ...
The Lions had plenty of issues besides that 2-point play Saturday. Derrick Barnes whiffed on a would-be safety that led to Lamb’s long TD, Goff threw two interceptions, including one late in the ...
Minimal group paradigm. The minimal group paradigm is a method employed in social psychology. [1][2][3] Although it may be used for a variety of purposes, it is best known as a method for investigating the minimal conditions required for discrimination to occur between groups. Experiments using this approach have revealed that even arbitrary ...
