Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study is a within-subjects/between-subjects design with five arms and involves comparisons between pre-intervention and post-intervention between: (a) Initial psychological states of the participants, and (b) After inhalation of the stimuli. Participants will be randomly allocated to one of the five experimental arms.
For medium effect sizes assumed (f = 0.25), 5 groups and two measurements in time (pre and post stimulus administration) a minimum of 80 subjects total sample size is needed.
Affective states (relaxation, contentment, happiness, motivation, tension), as well as data on mood; depression, anxiety, and stress will be assessed.
Data about familiarity, pleasantness and intensity of the stimuli will also be collected.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Fragrance 1 Group
At-home administration of one of the four active stimuli (fragrances), according to the following protocol:
1. Participants will complete a series of psychological scales (pre-measurements), tapping into mood, affective states, well-being.
2. Participants will inhale the fragranced stimulus for approximately 10 minutes.
3. After the completion of step 2, participants will engage in a neutral activity for about 15 minutes.
4. Participants will complete a series of psychological scales (post-measurements).
5. Participants will repeat this protocol one week apart.
