    Abstract

    Recent reports suggest that enhancement of memory performance while chewing gum is a fairly robust phenomenon. The processes underlying the effect are not known, but may involve glucose delivery, context-dependent effects and arousal mechanisms amongst others. This brief commentary outlines the main findings from these studies and raises some issues regarding interpretation, methodology and future research directions.
