Two point discrimination is quite an old technique. The skin is touched simultaneously with two points, various distances apart. If the two points are sufficiently close together, they are perceived as one point. The threshold distance for this effect varies across the body, and can be taken as an indicator of the sensitivity and/or receptor density on that part of the body.

In tactile localisation studies, the skin is touched at various points, on a body part that is out of sight of the participant. The participant then has to indicate (by pointing at a picture of their arm, or clicking on an image on a computer screen) where they think they were touched. It turns out that people aren't that good at this; in fact, some interesting biases emerge.

Where on the body would you expect the error of localization and the two-point discrimination threshold to be lowest?

The error of localization and two-point discrimination threshold are expected to be lowest on body parts with a high density of sensory receptors, such as the fingertips and lips. These areas have a high resolution of touch sensation due to the close spacing of tactile receptors, allowing for more accurate localization and discrimination of sensory stimuli.


What is the relationship between accuracy of subject's tactile localization and results of two point discrimination?

On your fingertip you were closer, on your forearm you were slightly farther away. (don't write this part on your paper, buuuuut be sure this is consistent with what YOU noticed in lab) Your nerve receptors are closer on your fingertip because you were able to sense more.


What is precision grip?

A precision grip is the way you grab an object between the opposed tactile pads of the tips of the thumb and the fingers. Tactile pads are areas of the skin that are especially sensitive to pressure.

What was your hypothesis for the tactile localization activity?

Your teacher does not want to hear the hypothesis from some random person on the internet. The idea is for you to form your own hypothesis - just put down what you guessed would happen and be honest about it instead of trying to cheat.
