Abstract

Betel nut is a common stimulant in many Asian countries, including Taiwan. However, few behavioral studies focusing on the betel nut chewing effects were reported. The current study examined the effects of betel nut chewing on the useful field of view (UFOV) under sleep deprivation. After one night of deprived sleep, habitual chewers and nonchewers chewed either betel nut or gum before proceeding to the UFOV subtests. In the UFOV subtests, participants needed to identify the central target, divide their attention to the peripheral target, and detect the peripheral target embedded in the distractors while identifying the central target. We report that betel nut chewing could broaden the UFOV size for the habitual chewers, but not for the non-chewers. The implication for people often chewing betel nut for refreshment during long-hour working is discussed.
