INSTRUCTIONS: Answer the questions below in association to the results. The experiment has already been performed! Experiment Background: 1. Method of constant stimuli. Decided on 4-6 distances to test, including the smallest ~2mm. The Participant closed their eyes while the Researcher used the compass to gently touch one or two of the prongs onto the participant's skin (just barely touch the surface of the skin). The participant answered "Did you perceive two points?" (yes/no). The Recorder took note of each answer under each distance as well as whether the Researcher did use 1 or 2 prongs. Presented each distance at least 5 times with a mix of 1 and 2 contact points. 2. Method of adjustment. Started at the smallest distance gently touch both prongs to the participant's skin. Gradually spread the prongs until the participant notices two points. Recorded this distance between prongs. Results: Region: Finger tip Distance: 2mm Was there two points? Was there two points? 2 Answer: 2 Yes, there is two points Answer: Distance: 5mm Was there two points? No, there is one point No, there is one point Distance: 8mm Number of points applied by researcher 1 Answer: Yes, there is two points Answer: 0 No, there is one point 2 2 Number of points applied by researcher 1 0 2 3 Answer: Yes, there is two points Answer: 0 2 1 1 Number of points applied by researcher 2 1 0 2 Region: Palm Distance: 2mm Was there two points?
