Walker (1996) presents a cache model of the operation of attention in the processing of discourse as an alternative to the focus space stack that was proposed previously by Grosz and Sidner (Grosz 1977a; Grosz and Sidner 1986). In this squib, we present a critical analysis of the cache model and of Walker's supporting evidence from anaphora in discourses with interruptions and from informationally redundant utterances. We argue that the cache model is underdetermined in several ways that are crucial to a comparison of the two models and conclude that Walker has not established the superiority of the cache model. We also argue that psycholinguistic evidence does not support the cache model over the focus stack model.

“As a temporal art,” Adorno observed, “music is bound to the fact of succession and is hence as irreversible as time itself. By starting it commits itself to carrying on, to becoming something new, to developing. What we may conceive of as musical transcendence, namely, the fact that at any given moment it has become something and something other than it was, that points beyond itself—all that is no mere metaphysical imperative dictated by some external authority. It likes in the nature of music and will not be denied.”
