“Process and perish” or multiple buffers with push-down stacks?

Abstract

AbstractThis commentary raises two issues: (1) Language processing is hastened not only by internal pressures but also externally by turn-taking in language use; (2) the theory requires nested levels of processing, but linguistic levels do not fully nest; further, it would seem to require multiple memory buffers, otherwise there's no obvious treatment for discontinuous structures, or for verbatim recall.
