Summary
The results demonstrate that chewing gum is associated with selective enhancement of tasks assessing aspects of working memory and long-term declarative memory.
Tests of attention demonstrated no enhancement effects as a result of chewing gum, although Simple Reaction Time was significantly slower during the sham chewing condition.
This may reflect allocation of attentional resources to the performance of this unfamiliar behaviour
Such an effect may also underlie the apparent reduction in immediate and delayed word recall scores in the sham chewing condition, suggesting that these processes are involved in memory consolidation.
Chewing gum elevated heart rate significantly above that in the sham chewing and control conditions.
