Bradley and Kjungja (1982) experimented with the perception of subjective triangles. When you look at three points that form a triangle, there is a subjective impression of lines connecting those points to form the contours of the triangle. Bradley and Kjungja asked participants to view the subjective triangle while it was stationary and again while it was rotating in a circle. The participant was instructed to say whether the subjective contours were stronger while the triangle was stationary or while it was rotating. Out of 37 participants, 35 said that the contours were stronger when the triangle was rotating. How could they test whether this difference was significant (although here a formal test isn't really needed)?
