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 \u201cBLUE\u201d 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 \u201cBLUE\u201d 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 \u201cerror awareness\u201d by pressing a separate 'error signaling button' (e.g., button 2) on the trial following a commission error.", "id": "tsk_nzi0bkdoO8a23", "type": "task", "conditions": [], "concepts": [], "indicators": [], "external_datasets": [], "implementations": [{"creation_time": 1520360083545, "implementation_name": "Inquisit", "last_updated": 1520360083545, "implementation_description": "The Inquisit Lab/Inquisit Web implementation of the EAT", "name": "Inquisit", "id": "imp_EQvPlPzTMkrZj", "implementation_uri": "http://www.millisecond.com/download/library/errorawarenesstask/", "relationship": "HASIMPLEMENTATION"}], "citation": [{"creation_time": 1520360130606, "citation_pmid": "", "last_updated": 1520360130606, "citation_desc": "Neural mechanisms involved in error processing: A comparison of errors made with and without awareness", "citation_type": "", "citation_url": "http://linkinghub.elsevier.com/retrieve/pii/S1053811905002715", "citation_comment": "", "citation_authors": "Robert Hester, John J.
