共感覚と言語習得

For those who do not experience extra-sensory stimulation associated with written and spoken language, the idea of Synesthesia is likely somewhat difficult, at least initially, to fully comprehend. There are many different types of synesthesia, such as taste associated with sound or a type in which perceived sensation, or even pain, is associated with sounds or written words. This discussion will, however, focus primarily on some of the more frequently observed, and researched, types of synesthesia, which are grapheme-color synesthesia, sound-color synesthesia, and spatial-sequence synesthesia. Understanding how these varieties of synesthesia function to facilitate, or in some cases impede, language acquisition can help those who are involved with education to cater their methods to the strengths and needs of the learner. This knowledge may also lead to the discovery of new strategies and methodologies of language instruction and acquisition that benefit learners with and without synesthesia.
