Explanation:

Identify the instrument in the image

The image shows a caliper (specifically, a vernier caliper or a simple plastic caliper).

Determine the physiological test associated with this instrument

In sensory physiology labs, calipers are used to measure the minimum distance at which two distinct points of contact can be felt as separate. This is known as the two-point discrimination threshold.

Map the test to the corresponding sensory modality

The two-point discrimination test evaluates tactile acuity, which is a component of the somatosensory system, specifically the sense of touch.
