描述了一种与工作类型有关的精油感知香味的感官测试。对香味的感知由13对不同的形容词来描述。每项工作前、后吸入一种香味后记录分数，并通过学生对脑力劳动、体力劳动和听环境音的t检验，检验13个印象描述符的分数变化的统计学意义。然后，根据印象描述符的t检验认为有意义的项目的数量，通过符号检验来评估与工作类型有关的对香水的感知的变化。这项研究考察的精油是薰衣草、迷迭香、芳樟醇、薄荷、马郁兰、豆蔻、檀香、罗勒和酸橙，研究发现，吸入精油会导致不同工作类型的人对香味的主观感受不同；例如，与工作前相比，脑力劳动后吸入罗勒会产生比工作前更好的印象，而芳樟醇、薄荷和酸橙与脑力劳动相比，每种精油都会产生不好的印象。在这些样品中，芳樟醇在感觉测试和便携式前额表面脑电(IBVA-EEG)中产生了最有趣的结果。根据IBVA-EEG测量，在听到环境声音后吸入芳樟醇不仅在感官测试中产生了更好的印象，而且与工作前相比，工作后的β波也有更大的下降；这与脑力劳动的情况相反，例如，脑力劳动导致情绪激动的倾向伴随着β波的增加。(1997年9月29日收到；1998年8月31日经修订后接受)
A sensory test of the perceived fragrance of essential oils in relation to the type of work is described. The perception of fragrance was described by 13 contrasting pairs of adjectives. Scores were recorded after inhaling a fragrance before and after each type of work, and the statisticalsignificance of the change of score for the 13 impression descriptors was examined by Student's t-testfor mental work, physical work and hearing environmental sounds. The change in perception of a fragrance in relation to the type of work was then evaluated by a sign test in terms of the number of items regarded as significant by the t-test of the impression descriptors. The essential oils examined in this study were those of lavender, rosemary, linalool, peppermint, marjoram, cardamom, sandalwood, basil and lime, and it was found that the inhalation of an essential oil caused a different subjective perception of the fragrance depending on the type of work; for example, inhalation of basil after mental work produced a much more favorable impression than that before work, in contrast to the cases for linalool, peppermint and lime with mental work, which each produced an unfavorable impression when compared to that before work. Among these samples, linalool produced the most interesting results in the sensory test and by portable forehead surface electroencephalography (IBVA-EEG). Based on the IBVA-EEG measurements, linalool inhalation after hearing environmental sounds not only resulted in a much more favorable impression in the sensory test, but was also accompanied by a greater decrease in beta waves after work in comparison with that before work; this is in contrast to the case of mental work, for instance, which resulted in a tendency for agitation accompanied by an increase in beta waves.
