“…Aromas have been found to bias differentially individual's attention toward either global or local representational levels (for reviews, see Hertz, 2009;Johnson, 2011). The stimulating aroma peppermint is supposed to increase arousal and induce a more focused attentional state, while lavender, a calming olfactory fragrance, is considered to induce relaxation and a broader attentional state (Barker et al, 2003;Basevitch et al, 2011;Ho & Spence, 2005;Ilmberger et al, 2001;Moss, Cook, Wesnes, & Duckett, 2003).…”

Increasing evidence suggests that`aromas have distinctive effects on the allocation of attention in space: Arousing olfactory fragrances (e.g., peppermint) are supposed to induce a more focused state, and calming olfactory fragrances (e.g., lavender) a broader attentional state. Here, we investigate whether odors have similar effects on the allocation of attention in time. Participants performed the attentional blink (AB) task, known to produce a deficit in reporting the second of two target stimuli presented in close succession in a rapid sequence of distractors, while being exposed to either a peppermint or a lavender aroma. In two experiments using a between-subjects and a within-subjects design, respectively, we show that the two odors have specific effects on attentional control: As compared with the calming lavender aroma, the arousing peppermint condition yielded a larger AB. Our results demonstrate that attentional control is systematically modulated by factors that induce a more or a less distributed state of mind.

“…Another research noted that human psychological functioning that includes perception and mood to cognitive processes and behaviors have the potential to be affected by a fragrance (Lenochova´ et al, 2012). (Johnson, 2011) also stated that the human performance in all contexts come from the effect of fragrance.…”

Previous studies have indicated that certain types of fragrance in the vehicle are useful in keeping the driver alert. This study was conducted to evaluate the effect of lavender or vanilla flavor fragrances toward driving performance. Ten human subjects were tested using the driving simulator in three different conditions; driving with vanilla, lavender flavor fragrance and driving without fragrance. A questionnaire was distributed to examine the emotion states of the driver after driving the simulator. Our results indicate that fragrance did not affect the speed reduction. The emotions of the drivers were calm due to the presence of the fragrance.

“…For example, the essential oil of fennel contains a form of estrogen-like compounds that may be effective for female problems such as lactation and menstruation. -Psychological: by inhalation, the olfactory area of the brain (limbic system) undergoes an action triggered by the essential oil molecules and then, chemical and neurotransmitter messengers provide changes in the mental and emotional behavior of the person (Buchbauer, 1993;Johnson, 2011;Shibamoto et al, 2010). Lavender and lemon essential oils are examples for their sedative and relaxant properties.…”
