Laurent HEURLEY: La révision de texte: l’approche de la psychologie cognitive: During the past 25 years many studies have been done on text revision in cognitive psychology. However, one must aknowledge that revision is still an ill-defined concept. Revision definitions are rarely expressed in operational terms and differ from one researcher to another. This paper aims at clarifying what we mean by text revision by reviewing the main definitions available in cognitive psychology, the methods that are used to analyse text revision and the different subprocesses of the revision process that researchers have identified.
