Inclusion Criteria

Students who are generally healthy, between 18-25 years of age, do not have a psychiatric condition specifically an anxiety disorder or post-traumatic stress disorder, who are not pregnant or possibly pregnant, who have a good (self-reported) sense of smell, no severe allergies, no asthma, will be included in the study. Participants will not be on any prescribed medications other than oral contraceptives. Participants who have a severe cold or the flu at the time of the lab visit will be rescheduled.

Exclusion Criteria

Students who indicate not to be healthy in general, are below 18 years or above 25, to have a psychiatric condition, or, specifically an anxiety disorder or post-traumatic stress disorder, low-average sense of smell, to be pregnant or possibly pregnant, to have severe allergies or asthma will be excluded from the study. Orange odor may have anxiolytic or sedative effects. Participants who are on prescribed medications will be excluded from the study. We will not check whether these are anxiolytics or sedatives in order not to invade the participant*s privacy too much (advice of M.D. involved in study, Dr. Klopping-Ketelaars).
There is no specific reason for excluding pregnant women in the sense that this procedure is potentially harmful for pregnant women (or the unborn foetus), but we think it is undesirable to expose pregnant women to undue stressors.
