摘要

The influence of low concentrations of two odors (lavender and orange) and a non-odorous (control) condition on the performance on two tests (vigilance and calculating ability) was investigated in 293 persons who were unaware of the presence or non-presence of odor. Each subject performed each of the tests twice under different odor conditions. The results indicated that orange odor had a positive influence on performance in both tests, whereas the results obtained under lavender did not differ from those obtained under the control condition. In the mathematical test men made fewer errors than women. No gender difference was found in the vigilance type task of the letter counting test. In the mathematical test the error rate was significantly lower in the second session than in the first. No such learning effect was found in the letter counting task. Performance was not related to independent measures of odor pleasantness and odor familiarity, which were both more positive in people who could identify the odor than in people who could not identify it. Surprisingly, people who could identify the odors showed a better performance on the vigilance test. independent of the odor condition to which they had been exposed. For the calculating task no such difference between the odor identifiers and non-identifiers was found. The results of the experiment do not support the view that the effects of odors on performance are mediated by the feelings of pleasantness that the odors evoke.
