This special issue of the International Journal of Psychology had its origins in the Quebec 98 Conference on Short-Term Memory, held in Quebec City, Canada, in June 1998. Following this conference, participants were invited to submit contributions based on, and expanding upon, their presentation at this conference. The enthusiastic response made it possible to collect the exciting selection of articles that you will find herein. It must be noted that because of the finite journal space available, the editors and reviewers were faced with the difficult problem of selecting only a limited number of the excellent articles that were submitted. The outcome of this process is this special issue, which we believe provides an up-to-date overview of current research on short-term/working memory, including the challenges, controversies, and recent theoretical advances in this field.
