Lab 3 homework
●The experiment used calipers with two points to test sensitivity on both the finger and
forearm.The points are set at six different distances apart including 0,.5,1.0,1.5,3 and 5cm
apart. Next, testing the finger and forearm with the 6 different distances.
●The percentages of the time the two points were felt at each of the distances on the finger
is at 0.0cmis 0% felt 0 times , 0.5cm is 40% felt 2 times , at 1.0cm is 80% felt 4 times, at
1.5cm is 100% felt 5 times, at 3.0cm is 100% felt 5 times, at 5.0cm is 100% felt 5 Times.
●The percentages of the time the two points were gets at each of the distances on the
forearm is at 0.0cm is 0% felt 0 times, at 0.5cm is 0% felt 0 times, 1.0 cm is 0% at 0
times, 1.5 cm is 0% felt 0 times, 3.0 cm is 80% felt 4 times, 5.0 cm is 100% felt 5 times.
●Touch sensitivity on the finger is more sensitive then touch sensitivity on the forearm
because they’re many more sensory neurons on your fingertips
●One area is more sensitive than the other area because there is a larger brain area devoted
to receiving their signals, meaning more sensitivity.
