The Response Time of the Stroop Test Is Delayed during Lemon-Flavored Gum Chewing

摘要

In the present study, we examined the cognitive function during mastication of lemon-flavored gum, which is said to enhance cerebral blood flow. Nine healthy subjects (8 female and 1 male) participated in this study. Subjects chewed the gum for 3 min after fasting for 2 h and conducted a Stroop test while continuing to chew. At the end of all answers, gum chewing ended. The response time in the Stroop test was used as an indicator of cognitive function. We set the three conditions (lemon-flavored gum, mint-flavored gum, no gum chewing). There was no significant difference in reaction time between chewing mint-flavored gum and not chewing ( p >0.05). However, the response time during chewing gum with a lemon flavor was significant slower than the conditions with mint-flavored gum and without gum chewing ( p.
