This study was performed to evaluate the EmojiGrid for the affective appraisal of odors. Observers (N=56, 24 males, mean age=24.3±4.6) sniffed 40 randomly presented odors (27 food and 13 non-food smells) with a wide range of perceived hedonic valences, ranging from unpleasant and arousing (e.g., feces, fish), via pleasant and calming (e.g., clove, cinnamon) to pleasant and stimulating (e.g., peach, caramel). After sniffing, the participants reported their affective appraisal of each odor using the EmojiGrid. The resulting mean valence and arousal ratings closely agree with those that were obtained with alternative rating tools in previous studies in the literature. Also, we find that the EmojiGrid yields the typical universal U-shaped relation between mean valence and arousal that is commonly observed for a wide range of affective sensory (visual, auditory, tactile, gustatory) stimuli. We conclude that the EmojiGrid can be used as an affective self-report tool for the assessment of odor-evoked emotions.
