a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Participants are asked to distinguish a gabor display that is "popping out" from one that is not, and rate their confidence on the decision on a scale of 1 (low confidence) to 6 (high confidence). Full details are available:

Medial and Lateral Networks in Anterior Prefrontal Cortex Support Metacognitive Ability for Memory and Perception

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


You must specify conditions before you can define contrasts.

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.

response time
distance between actual location and participant's response
precision (distance apart at which subject perceives each stimulus separately)

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).
