Does chewing gum affect short-term memory?

Over the last 10 years there’s been a lot of research on whether there is a link between chewing gum and a higher cognitive function. Several different researches have showed that a significant affect exist whereas others have shown no such results. The purpose of this research is to get further results on the subject, by using word recall after verbally presenting the words. Repeated measures where used on a random group of volunteers from the age of 18. There short-term memory was tested in four different recall tests, where two were with chewing gum and two were without. The results didn’t show any statistically significant findings between chewing gums and an improvement in memory recall. Further testing needs to be done on the subject
