The effect of lemon fragrance on simple mental performance and psychophysiological parameters during task performance

The purpose of this study is to effectively utilize fragrance in order to form a comfortable working environment, for which we obtained necessary data. The subjects were 14 female students. We made them do addition work in laboratories with and without lemon fragrance, and investigated their task performances, physiological changes and mood conditions. Our results showed that, although the existence or nonexistence of fragrance did not affect their work efficiency, it was revealed that fragrance mitigated exhaustion and maintained vigor.
