Perceived and measured similarity provide a way to relate human perception to measured physical differences, and to link both to Psychologically relevant attributes such as memorability and confusability. This work extends previous research using image based measures to case of underlying three- dimensional (3D) face shape. 3D shape has the advantage of being a property of the face not the image. Two groups of nine naive observers were asked to sort animation of twenty randomly generated 3D faces into an unspecified number of groups on the basis of perceived similarity. Co-occurrence of faces in these groups was then converted into a measure of perceived similarity. The correlation with physical measures will be reported. After the sorting task, observers were also given a surprise old/new recognition task based on the twenty faces they had sorted and an additional twenty faces generated in the same manner. New and Old faces were counterbalanced across the two groups of observers. Hits and false alarms identify both memorable faces and faces that can be reliably rejected as not having been seen before. Again, these can be linked to physical and psychological similarity.
