We are conducting a pilot study to investigate subjective, physiological, and behavioural measures of stress after exposure to the pheromones (pheromones are chemical substances produced and released into the environment by an animal, especially a mammal or an insect, which affect the behaviour or physiology of others of its species).

Who can take part?

If your answer to each of the following statements is yes, you should be able to take part:

  • I am aged between 18 and 40 years;
  • I have good physiological and psychiatric health;
  • English is my first language, or I have an equivalent level of fluency;
  • I will not drink alcohol or take drugs within 24 hours of the study session;
  • I am not currently pregnant or breastfeeding;
  • I am not a daily smoker;
  • I do not have uncorrected visual, olfactory or auditory impairments;
  • I have no physical illness or abnormalities;
  • I have not had a cold, flu or respiratory infection within the last 4 weeks.

What’s involved?

You would be asked to take part in two separate test sessions, lasting approximately 60 minutes each. During each session, we would ask you to play a computer game using a joystick after being exposed to either a pheromone or a placebo. We would also assess your heart rate and blood pressure and ask you to complete a series of brief emotion and mood questionnaires.

You would be reimbursed £10 for your time.
