This task tests whether children understand the principle of conservation, or the idea that two objects are still equivalent after a transformation of one of them. Specifically, the "Water Jar Task" tests if children have attained "conservation of liquid quantity." The child is asked to assess if the same amount of water in different glasses is in fact equal.

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.


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).
