The EAT is a modified Go/No-Go response inhibition paradigm providing behavioral and neural indices of both error awareness and inhibitory control. Participants are shown color words (e.g., red, blue, green) printed in congruent or incongruent fonts (as in a Stroop task) such that most stimuli are congruent (80%; e.g., the word “BLUE” in blue font). Congruent stimuli are Go trials requiring a button-press response (eg., button 1). In contrast, participants are to withhold button-presses when either the same color word is repeated on two successive trials (No-Go Rule-1) or an incongruent stimulus is presented (e.g., the word “BLUE” in red font; No-Go Rule-2). Continuously monitoring both No-Go rules is difficult and participants are predisposed to monitor for REPEAT (Rule-1) more so than INCONGRUENT trials (Rule-2). This leads to a sufficient number of errors (~45%), a portion of which remain undetected by participants (~10-20%). The task begins with words presented for 900ms followed by a 600ms inter-stimulus interval (ISI). To equate task performance across groups and maintain overall errors at ~45%, task difficulty dynamically adapts based on individual performance by varying the stimulus presentation and ISI durations. Participants indicate “error awareness” by pressing a separate 'error signaling button' (e.g., button 2) on the trial following a commission error.

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).
