Summary

A behavioral study that will examine how pain perception is affected by different types of conditioning and by context, with a few participants and multiple sessions ("N-of-few" design).

Conditions

  • Healthy

Interventions

BEHAVIORAL

Symbolic conditioning

Participants will learn associations between cues and thermal stimuli with varying temperatures (low vs. high) through symbolic conditioning (no actual heat stimuli, only pictures of thermometers)

BEHAVIORAL

Conditioning

Participants will learn associations between cues and thermal stimuli with varying temperatures (low vs. high) from experience (with actual heat stimuli).

BEHAVIORAL

Instructions

Participants will learn associations between cues and thermal stimuli with varying temperatures (low vs. high) from verbal instructions.

BEHAVIORAL

Counterfactual

Thermal stimuli will be either the better outcome or the worse outcome out of two possible outcomes.
