聴覚と視覚における多感覚情報処理 ―刺激の複雑性との関係

発表者: Charles Spence (オックスフォード大学)
司会者: 菊谷 まり子(金沢大学)

 There has been a dramatic growth of interest in the crossmodal correspondences over the last 50 years or so, with the majority of this research having focused on crossmodal associations between stimuli presented in the auditory and visual modalities. While traditionally conceptualized in terms of
synaesthesia, there is now an extensive body of scientific evidence demonstrating the existence of audiovisual crossmodal correspondences in the general( i.e., non-synaesthetic population) extending all the way from the perceptual affinity between simple sensory features( such as pitch, hue, size, and shape), through to the correspondences that many people feel between musical excerpts and paintings, or even artistic/architectural styles. Over the years, a number of explanations have been put forward for the crossmodal correspondences, including the statistically-, structurally-, semantically-/lexically-, and emotionally-mediated accounts. What is more, commentators from diverse theoretical backgrounds have also suggested a physical basis for the mapping between colour and pitch, given the fact that both can be represented on circular dimensions. Certain correspondences may be based on the shared connotative meaning of stimuli as, for example, assessed by means of the semantic differential technique. There may also be a place for ‘stylistic correspondences’ in the case of complex, culturally-meaningful auditory and visual stimuli, such as music, paintings, and architecture. While the existence of audiovisual correspondences has long been of interest to those artists, such as Scriabin and Kandinsky, who were once inspired by the phenomenon of synaesthesia, gaining a better understanding of the robustness and regularity/automaticity of such crossmodal correspondences is becoming especially relevant to those interested in developing more intuitive, and hence hopefully less cognitive-demanding, audiovisual sensory substitution devices for those who may have lost a sense.
