Examples of purity and intensity scores. Purity scores were based on relative difference of angles between the radius line directly crossing the middle of the field of a given emotion field (e.g., fear) and the radius line crossing through the answer point. In this example the answer “A” received 1 point as it is located directly on the line. Answer “B” received 5 point as α₁ is 5 smaller than α. Answer “C” received 0 points as it is located outside of the emotion field (displayed emotion is not recognized as intended). Intensity scores were calculated as the relative distance of segment “ab” starting from point “a” (border of internal wheel labeled neutral scored 0) to the wheel border—point “b” (scored 1). Thus, answer “A” was scored 58 on the intensity scale.
