Sum of confidence ratings from the 18-AFC experiment (Experiment 2) for each stimulus (Stim.) and each category for the first 15 stimuli (of 924). Category profiles are the distribution of category responses for each stimulus and reveal the extent to which multiple category terms apply to the same stimulus. Stimulus profiles are the distribution of stimuli that were allocated to each category and reveal the extent to which category terms are correlated with one another. Stimulus profiles were used to reveal the latent perceptual space of materials for our stimuli (factor analysis; Fig. 4 ), and category profiles were used to calculate material dissimilarity scores between each pair of stimuli (representational similarity analysis; Supplementary Analysis B and Supplementary Fig. 15 ).
