a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Subjects performed two alternate tasks, namely tell if a horizontal line is crossed precisely in the middle (LANDMARK) and tell if a horizontal line is crossed at all (DETECTION). The following instructions were used: “Press the button with your left index finger if the line is bisected in the middle otherwise press the button with your right finger” or “Press the button with your left index finger if the line is crossed otherwise press the button with your right finger”.

CONDITIONS

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

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).
