Abstract

Extant studies have revealed enhancing effects of scent on performance. The role of scent, and emission method, in the context of performing repetitive tasks over prolonged duration in promoting alertness, vigilance, and memory was examined. Seventy-three participants were randomly assigned to one of three conditions (no scent, peppermint scent emitted continuously, or peppermint scent emitted intermittently) while tasked to monitor and identify suspicious cues for close to 2 hr. Pre- and post-intervention surveys, psychomotor vigilance test, and eye tracker were used as study instruments. Results showed that scent directly enhanced information recall and mitigated the deterioration of alertness, especially as subjects became fatigued. Intermittent emission showed stronger effects over continuous emission in marginally enhancing alertness and memory. Scent did not appear to promote greater vigilance. Suggestions for future studies and implications for management of employees in fatigue situations are discussed.

气味和气味释放方法的影响：对工人在疲劳条件下的警觉、警觉和记忆的影响

现存的研究已经揭示了气味对工作表现的增强作用。在长时间执行重复性任务的背景下，气味和释放方法在提高警觉性、警惕性和记忆力方面的作用被检查。73名参与者被随机分配到三种条件中的一种(没有气味，持续散发薄荷气味，或间歇性散发薄荷气味)，同时被要求监测和识别可疑线索近2小时。采用干预前后问卷调查、精神运动警觉性测试和眼动仪作为研究工具。结果表明，气味直接增强了信息回忆，减轻了警觉性的恶化，尤其是在受试者疲劳时。间歇发射对警觉性和记忆力的微弱增强作用强于连续发射。气味似乎并没有提高警惕性。讨论了未来研究的建议以及对员工疲劳状况管理的启示。
