薄荷和依兰精油调节认知表现和情绪

This study provides further evidence for the impact of the aromas of plant essential oils on aspects of cognition and mood in healthy participants.

本研究进一步证明植物精油对健康志愿者的认知和情绪的影响。

One hundred and forty-four volunteers were randomly assigned to conditions of ylang-ylang aroma, peppermint aroma, or no aroma control.

144名健康志愿者被随机分配到依兰气味组、薄荷气味组，无芳香气味组。

Cognitive performance was assessed using the Cognitive Drug Research (CDR) computerized assessment battery, with mood scales completed before and after cognitive testing.

使用认知药物研究（CDR）计算机评定表评估认知表现，认知测试前后完成情绪量表测试。

The analysis of the data revealed significant differences between conditions on a number of the factors underpinning the tests that constitute the battery.

对数据的分析显示，构成评定表的一些因素之间的条件有很大差别。

Peppermint was found to enhance memory whereas ylang-ylang impaired it, and lengthened processing speed.

发现薄荷增强了记忆力，而依兰则使其受损，并延长了处理速度。

In terms of subjective mood peppermint increased alertness and ylang-ylang decreased it, but significantly increased calmness.

基于主观情绪，薄荷增加警觉性，而依兰降低警觉性，但显著增加镇静作用。

These results provide support for the contention that the aromas of essential oils can produce significant and idiosyncratic effects on both subjective and objective assessments of aspects of human behavior.

这些结果支持一个论点，即精油的香气能够对主观和客观评价人类行为的一些方面产生重要的和特别的作用。
