Abstract
My previous research using NIRS clarified that there are individual differences in the ability to create ideated tactile sensation and some people do not naturally experience any tactile stimulation. In this research phase, some photo colorization practices which focused on tactile sensation were administered to the same participants as in the previous research, and the result clarified that now all participants could ideate tactile sensations during visual observation of photographs. This result suggests that art education is capable to develop long-term potentiation of synapses for visually triggered ideated tactile sensations. Also, related survey research found that 3 to 4 % of respondents had aphantasia, and 40% of university students surveyed had some difficulty recalling visual images. The results of this research suggest that we need support tools based on cognitive diversity inclusion for expression and appreciation processes.
