The participants were asked to pick up the first test cloth (e.g. A1 ) in both hands and instructed to gently manipulate it close to their nose, noting how intense the perfume was. The participant was then instructed to pick up the blank cloth and treat it in the same way. Lastly the participant picked up the second of the test cloth (e.g. A2), manipulating it close to the nose and judge if it was more or less intense than the first test cloth.
