Individual Differences in Placebo Analgesic Effects

Person by Situation Interaction: Matching Suggestions to Participants' Motivational Styles

This study examines the effects of placebo suggestions tailored to match or mismatch individual participants' motivational styles-an issue of person-situation 'fit' with important effects in public health settings, but which has been ignored in past research.

Inclusion Criteria:

• Healthy participants
• Dominant promotion focus or dominant prevention focus (based on our screening)

Exclusion Criteria:

• Currently or recently suffered from chronic pain (based on screening)
• Cannot tolerate heat pain applied to the forearm, based on a calibration task at the beginning of the experiment
