Research is reviewed on the effects of chewing gum on stress, alertness and cognition (including findings from cognitive neuroscience). There is some evidence that chewing gum reduces chronic stress, while effects on acute stress have been less clear in an experimental context. A robust effect of gum chewing on subjective alertness has been observed. However, findings on chewing gum and cogniti...

The experiment examined the prediction that chewing gum at learning and/or recall facilitated subsequent word recall. Chewing gum at learning significantly impaired recall, indicating that the chewing of gum has a detrimental impact upon initial word encoding. In addition, a context-dependent memory effect was reported for those participants who both learned and recalled in the absence of gum; ...

People of all cultures chew gum, and a variety of gums and gum-like substances have been enjoyed for thousands of years. The introduction and subsequent success of Nicotine chewing gum in the 1980’s paved the way for a more general acceptance of chewing gum as a drug delivery system. Improved technology and extended knowledge, together with the inclusion of medical chewing gum in the European P...

In a study published previously in this journal (Wilkinson et al., 2002), the effect of chewing gum on cognitive functioning was examined. The results of this study indicated that chewing a piece of gum results in an improvement of working memory and of both immediate and delayed recall of words but not of attention. In the present study, memory and a variety of attentional functions of healthy...

Two experiments re-examined whether chewing spearmint gum affects initial word learning and/or immediate recall for a word list. Both experiments failed to show effects of chewing gum at learning or recall, nor did they suggest that chewing gum produces a context-dependent memory effect. This was true when extraneous contextual cues at learning and recall were minimised (Experiment 2). Together...
