A hierarchical taxonomy ofperception of 51 emoji-like drawings based on data from a card sorting study, averaging across US and Chinese participants.
Note. Leaves (outer edge of the hierarchy) correspond to individual drawings. These drawings are paired based on correlations in the proportion of matches with each other drawing. These pairings are then linked iteratively based on the average correlations between the judgment profiles of the two sets of drawings they contain, so as to maximize the correlations in judgments of the drawings that are grouped together. The correlation corresponding to each linkage is represented by its distance from the center, with the grey outer edge corresponding to a correlation of 1 and the inner circle corresponding to a correlation of 0. The branches of the tree are colored according to 5 top-level clusters linked at a correlation greater than 0. All linkages shown correspond to correlations that are significantly higher than would be expected if the linked branches were correlated only by chance, based on the number of leaves contained in each branch (p < .05).
