Betel nut chewing and selected psychophysiological variables.
28 male operators of earth movers, with an average age of 30 years, after chewing various quantities of betel not, volunteered to participate in a laboratory study of visual choice-reaction time, digit span, eye-hand coordination, pulse rate, and blood pressure. Analysis of variance identified a statistically significant increase in pulse rate only. Given no significant decrement in scores on any work-related measure discussion concerns the possible use of betel put at the work: place and particularly as an antidore for drivers fatigue. Limitations of the study, implications of the findings, and suggestions for research are discussed.
