a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
The ANT is a task designed to test three attentional networks in children and adults: alerting, orienting, and executive control. Efficiency of the alerting network is examined by changes in reaction time resulting from a warning signal. Efficiency of orienting is examined by changes in the reaction time that accompany cues indicating where the target will occur. The efficiency of the executive network is examined by requiring the participant to respond by pressing two keys indicating the direction (left or right) of a central arrow surrounded by congruent, incongruent or neutral flankers.

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

No contrasts have yet been associated.

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).

"This is the same task as the one called "attention networks task". is duplicated."

Term History


Definition contributed by CWhite about one year ago:The Attention Network Test (ANT), designed by Fan and Posner, requires participants to quickly respond to cues given on a computer screen, while having their attention fixated on a center target.
