My associative trails lead me to the 'cognitive plausibility' of hypertext, and to the mythbusters who have soon eradicated it before it could bear fruit. For example Dillon, A. (1996). Myths, misconceptions, and an alternative perspective on information usage and the electronic medium. In J.-F. Rouet, J. J. Levonen, A. Dillon, & R. Spiro, (Eds.), Hypertext and cognition (pp. 25-42). Mahwah, NJ: Lawrence Erlbaum, cited e.g. here.
