The Geneva Emotion Wheel (GEW) is a measurement instrument for the self-report of emotional experience. It differs from instruments that require respondents to rate their feelings on a list of emotion words in that it organizes the emotion words to be rated in a theoretically justified two-dimensional system formed by the valence and power dimensions. 20 words are organized in a wheel-like format in this space, with opposite points of the spikes of the wheel representing the felt intensity. Different partially validated versions of the GEW have been widely used in research already. The GRID paradigm finally allowed determining the definitive location of emotion terms in the valence/power space. The chapter presents the results of an additional study and the most recent version of the GEW instrument.
