a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
This is an instantiation of the Ultimatum Game (UG) in fMRI. In this game, a proposer is charged with splitting a sum of money with a partner. The responder decides either to accept or reject this proposed offer. If accepted, the money is split as suggested, but if rejected then neither player receives anything. The parterns can be a combination of real people, computers. Offers are preceded by a picture of the partner for that round, and partner pictures are randomly paired to an offer amount. Full details of the task are available: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3594719/

CONDITIONS

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

CONTRASTS

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.

INDICATORS

No indicators have yet been associated.

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).
