What Did The 2 Point Discrimination Test Demonstrate? The two-point discrimination test is used to assess if the patient is able to identify two close points on a small area of skin, and how fine the ability to discriminate this are. It is a measure of tactile agnosia, or the inability to recognize these two
What Does Two Point Discrimination Tell You? The two-point discrimination test is used to assess if the patient is able to identify two close points on a small area of skin, and how fine the ability to discriminate this are. It is a measure of tactile agnosia, or the inability to recognize these two points
What Is The Relationship Between Receptive Field Size And The Two-point Discrimination Test? The receptive field varies in size. The larger the receptive field is, the greater the area that it detects changes in but also less precise perception, and vice versa. Hence, areas with the most sensitive two-point discrimination should have a high density
Where Is Tactile Discrimination Best? Localization is most accurate on the palmar surfaces of the fingers, especially the thumb and index finger. On the fingers it should be possible to discriminate two points separated by less than 5 mm; however, on the dorsum of the foot, a distance as great as 5 cm as the
What Is Tactile Agnosia? Abstract. Associative tactile agnosia (TA) is defined as the inability to associate information about object sensory properties derived through tactile modality with previously acquired knowledge about object identity. What does tactile agnosia mean? Tactile agnosia is the inability to recognize objects through palpation in the absence of elementary sensory deficits such
