Speechstuff and Thoughtstuff: Musings On the Resonances Created By Words and Phrases Via the Subliminal Perception of Their Buried Parts Douglas Hofstadter Indiana University How do we hear compound words? What effect does calling a brontosaurus by that name have on us, as opposed to Chinese people, who (in some sense of the word) hear it as "thunder dragon"? What if you had grown up thinking of a proton as a "firstbit" and of hydrogen as "waterstuff" -- would this change your view of the world? How? Or would it have no effect at all? These kinds of issues are seldom confronted in cognitive science, and yet for me they lie at the core of language. The talk will be a set of explorations on these and related themes involved words and concepts.
