To test the validity of claims by users that betel chewing heightens alertness and improves motor responses, the effect of betel chewing on simple and choice reaction times (SRT and CRT) was investigated in habitual users. Control consisted of chewing gum and practice groups. Both SRT and CRT were correlated with age. In the SRT task, reaction times were not different among the three groups studied. In the CRT task, only betel and chewing gum groups showed a significant shortening of reaction time, but the betel group had a higher degree of statistical significance in this effect. It is concluded that shortening of CRT from betel chewing is probably partly due to chewing itself and partly due to a cholinergic arousal mechanism.
为了检验槟榔咀嚼能提高警觉性并改善运动反应这一用户声称的有效性，研究了槟榔咀嚼对习惯使用者简单反应时间和选择反应时间（SRT和CRT）的影响。对照组包括嚼口香糖组和练习组。SRT和CRT均与年龄相关。在SRT任务中，所研究的三组之间反应时间没有差异。在CRT任务中，只有槟榔组和嚼口香糖组的反应时间显著缩短，但槟榔组在这一效应上具有更高的统计学显著性。得出的结论是，槟榔咀嚼导致CRT缩短可能部分归因于咀嚼本身，部分归因于胆碱能唤醒机制。
