45 students were required to sort 216 Frois-Wittmann pictures into a rack containing 6 main bins--(1) love, happiness, mirth; (2) surprise; (3) fear, suffering; (4) anger, determination; (5) disgust; (6) contempt--and an additional discard bin. Analysis of the distribution of pictures in the 6 main bins discloses a scale of continuous rather than discrete categories. The 6 steps are found to be reasonably equal, and the spread of judgments across the gap between steps 6 and 1 indicates that the scale is a recurrent or circular series.
