This chapter introduces the reader to the effects of aging on language production skills. The Introduction outlines the micro- and macrolinguistic dimensions of language processing. The second and third paragraph provide an idea of how aging affects micro- (i.e., lexical and grammatical) and macrolinguistic (i.e., discursive) aspects of language production. A conclusive paragraph reflects on the usefulness of ecological tasks such as discourse production tasks to obtain a coherent picture of language processing in aging.
