a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
The general task design is that a heat stimulus is applied to the skin and the participant rates the experienced sensation on a visual analogue scale. For this task, there are 9 runs. Runs 1,2, 4, 5, 6, 8, and 9 are “passive experience” runs, meaning that participants passively experience and rate the heat stimuli. Run 3 and 7 are “regulation” runs, meaning that participants can cognitively “increase” (regulate-up) or “decrease” (regulate-down) pain intensity. For complete details, see:

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.


In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

subjective ratings on a visual analogue scale

An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).


Distinct brain systems mediate the effects of nociceptive input and self-regulation on pain.
