Understanding how others perceive the tactile world is essential for human communication. Each individual has a unique and multidimensional tactile perceptual space, which makes it challenging to understand others' tactile perceptions within the spaces. This study investigates the cognitive ability and process of estimating another person’s subjective similarity of various textures, a key aspect of tactile perceptual space. Participants performed tasks to estimate how a target individual would rate the similarity of tactile stimuli pairs. Results showed that participants could partially infer target’s similarity ratings, and their estimated tactile similarity ratings converged toward an intermediate point between their own and the target's. The estimation process included exploration, adaptation, and overgeneralization phases. Moreover, participants' own similarity ratings shifted closer to those of the target after performing the task. These findings suggest that estimating another person’s subjective similarity between textures involves incorporating elements of the target's tactile perceptual space into one's own.
