SENSORY PHYSIOLOGY – Tactile Localization Tactile localization is the perception of a stimulus stimulus at a specific location on the body. The precision of locating the origin of the stimulus is associated with the stimulus intensity as well as the receptor density at the stimulus location. The more densely the receptors are located to one another, the more precisely you would expect to locate locate the point of stimulation. stimulation. Since receptors are not distributed evenly across the skin, different parts of the body have have different capacities to locate locate the stimulus. In this activity, we will attempt to determine areas of the body which may contain higher numbers of receptors.
PROCEDURE 1. The subject must sit with his or her eyes closed. 2.
The tester should have one toothpick; the subject should have the second toothpick in their dominant hand.
3.
The tester should touch the back of their of their partner’s non-dominant hand with the point of their toothpick and leave it there, kee ping it in one location.
4.
The subject will take their toothpick and carefully attempt to touch the same spot.
5.
When both toothpicks are on the back of the hand, measure the distance (in millimeters) between the two. This is known as the the error of localization. localization. Record this distance in the table. table.
6.
Repeat the procedure using the same body part, but at a slightly different location.
7.
Average the two distances measured between the two trials.
8.
Attempt this procedure again, this time the subject should hold the toothpick in their non-dominant hand.
9.
Continue this same procedure for each of the remaining body locations listed in the chart.
10. When both partners are finished, each person should use their own data to create a bar graph, plotting the average distance, and answer the questions that follow.

ANALYSIS 1.
As you observe the tactile localization distances measured, how do different areas of the skin compare? Are they the same? Do they vary? Briefly describe your answer.
Is the ability to localize a touch in a region related to how densely the touch receptors are located in a particular region? Briefly explain your answer.
Did you find a difference between the tactile localization of your dominant and non-dominant hands? This is likely not due to a difference in the concentration of touch receptors. What other factors might contribute to this difference?
Using your knowledge from the two-point sensory activity and this one, which regions not tested would likely produce a very accurate tactile localization? Briefly explain your answer.
