Investigation: Two Point Discrimination Test
Students investigate the sensitivity of different areas of the skin using a mathematical compass to stimulate mechanoreceptors. The procedure asks students to place the points of the compass on different areas, such as the forearm and the palm and have a test subject report whether one point is being felt or two points. The compass…
