Similarity-judgment RDM. Representational dissimilarity matrix (RDM) showing object-similarity judgments for a set of 92 colored object images. The RDM is based on similarity judgments from 16 human participants, averaged at the level of the dissimilarities. Each entry of the RDM represents the judged dissimilarity between two images. RDM values were transformed into percentiles for visualization (see color bar). The similarity judgments show four main clusters corresponding to humans, non-human animals, natural objects, and manmade objects, and a tight cluster of human faces.
