Abstract

Although chewing gum improves cognitive functions including attention, memory, alertness, and executive functions, recent studies reported that chewing gum during a cognitive task can differently affect the components of cognitive functions. We examined the effects of taste-and-flavor-free chewing gum on behavioral alertness assessed by psychomotor vigilance test (PVT) in 13 healthy adults. They performed 5-min PVT for three times; before, during the last 5 min of 8-min gum chewing, and 3 min after ceasing it. Sustained attention evaluated as the number of lapses (>1000 ms) improved both during and after chewing gum (P = 0.01). Although marginally significant shortening of overall reaction time to stimuli (RT) was observed both during and after chewing gum (P = 0.05), the fastest 10th percentile RT (RT without the influence of lapses) lengthened only during chewing gum. Our observations suggest that chewing gum may improve sustained attention but elongate reaction time.
