In studies of infants, especially those that measure looking behavior, there is usually a sequence of familiarization trials first, to give participants enough opportunity to encode the events, and (sometimes) to teach them a particular expectation. After this phase, infants are then shown the expected and unexpected outcomes.
The validity of this task hinges on how well-controlled the stimuli are. Oftentimes researchers run many conditions in order to narrow in on exactly what aspects of the stimuli participants are responding to.

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).
