Research on placebo analgesia commonly focuses on the impact of information about direction (i.e. increase or decrease of pain) and magnitude of the expected analgesic effect whereas temporal aspects of expectations have received little attention so far. In a recent study using short-lasting, low-intensity stimuli we demonstrated that placebo analgesia onset is influenced by temporal information. Here, we investigate whether the same effect of temporal suggestions can be found in longer lasting, high-intensity pain in a Cold Pressor Test (CPT).
