Adaptation

It is useful to allow the participant to acclimatize to the laboratory setting; simply being there may be highly stressful for some persons and may cause their baseline measurements to be elevated. During this period, the experimenter should take a few minutes putting the participant at ease. Like all parts of the protocol, this portion should be carefully scripted and piloted to ensure it has the desired effect. In some cases, it may be useful to have the subject come in on a day prior to the scheduled laboratory testing so he or she has a chance to get used to the experimental milieu.
