Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Placebo
All participants will participate in two sessions, one with a placebo suggestion that matches the participant's motivational style, and one with placebo suggestion that does not match their motivational style, in a pseudo-random order.
Placebo cream- "promotion" suggestion
Over-the-counter hand cream will be applied to participants' skin, but they will be told that they are given a highly efficient topical analgesic cream. The suggestion will be based on a "promotion" approach (promoting good feelings).
Placebo cream- "prevention" suggestion
Over-the-counter hand cream will be applied to participants' skin, but they will be told that they are given a highly efficient topical analgesic cream. The suggestion will be based on a "prevention" approach (preventing pain).
Control
Each session will also include a control phase, in which the same cream will be applied, and participants will be instructed that the cream has no analgesic effects.
Control cream
In a control condition, with the same cream as in the placebo interventions, participants will be instructed that the cream is a control cream with no effects.
