figure 5.7 Studying perception and culture Stimulus materials used in research on cultural factors in perception. Participants were first shown the “Original” image and were then shown a square (with no line in it) of a different size than the original square. Next, participants were asked to draw a line whose absolute length was the same as the original line, or one whose relative length was the same as the original. (The lower two images show lines drawn accurately under these two instructional conditions.)
