By way of definition, Aron and Aron (1997) wrote that sensory processing here refers not to the sense organs themselves, but to what occurs as sensory information is transmitted to or processed in the brain. [4] They assert that the trait is not a disorder but an innate survival strategy that has both advantages and disadvantages. [11] [12]
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.
Proponents have also claimed that adults may also show signs of sensory processing difficulties and would benefit for sensory processing therapies, [71] although this work has yet to distinguish between those with SPD symptoms alone vs adults whose processing abnormalities are associated with other disorders, such as autism spectrum disorder. [72]
For many sensory modalities, over a wide range of stimulus magnitudes sufficiently far from the upper and lower limits of perception, the 'JND' is a fixed proportion of the reference sensory level, and so the ratio of the JND/reference is roughly constant (that is the JND is a constant proportion/percentage of the reference level).
Sensory processing is the process that organizes and distinguishes sensation (sensory information) from one's own body and the environment, ...
The purpose of this form of tactile discrimination is to detect any defects in the Central nervous system such as lesions in the Brainstem, Spinal cord, Thalamus, or Sensory cortex. In order for this test to be carried out successfully, it is imperative that the subject's primary sensations be fully functional.

The 1980s, with the introduction of inexpensive computers, opened up a new door for cognitive neuroscience research. Currently, ERP is one of the most widely used methods in cognitive neuroscience research to study the physiological correlates of sensory, perceptual and cognitive activity associated with processing information.
