Participants had been 16 college college students who had been blind to the purpose of the experiment. Auditory stimuli used were impression sounds of sixteen real objects of 10 material classes . The stimuli were introduced to the participants in a classroom through a set of speakers. Each sound was repeated 15 times, and the members needed to make the material-category score for every of the thirteen classes by the end of the stimulus repetition. The score task required a seven-point probability ranking, similar to that utilized in the primary experiment however for participants scoring the ratings on a questionnaire sheet. From multidimensional scaling of the squared Euclidean distance of score vectors, we estimated the subjective similarity map of the sixteen sounds .
