22 Active Learning Exercise – 2-point discrimination

This slide show has instructions for measuring the tactile acuity of your fingertip and palm, using the Method of Constant Stimuli. In the process, you will create a psychometric function for each body part, and you will use it to determine what your two-point discrimination threshold is. A low threshold means you can distinguish two points that are very close to each other, which means you have good acuity.
