ABSTRACT
This conclusion presents some closing thoughts on the key concepts discussed in the preceeding chapters of this book. The book reviews the results of research on language performance and proposes a model of production and comprehension. Although recent developments in linguistics are taken into account, consideration of other requirements of a performance model leads to the conclusion that the grammar the speaker has in mind differs from the grammar as currently conceived of by most linguists. Much experimental research will be pointless as long as it is not based on a much firmer theoretical basis. Such a basis can be provided only by careful consideration of the available data and by using common sense, 'self-conscious common sense', in Quine's words, so as to arrive at a plausible model. Some readers will feel that one have failed to fulfill the expectations raised.
