Conflict and interference tasks

A task-relevant feature must be reported while a task-irrelevant feature of the same stimulus or of a distractor pulls toward a competing response; the cost on incongruent trials is the measure.

This family contains 8 tasks and cross-lists 2 more.

Emotional Stroop

Color-naming of emotionally valenced words; RT slowing on threat-related words indexes attentional bias to affective content. Engages 5 processesSelective attentionInterference controlEmotion recognitionAttentional captureConflict monitoring. 1 aliasAffective Stroop, 6 variationsThreat-Related Emotional StroopDisorder-Specific VariantsPositive vs. Negative Emotional StroopPictorial Emotional StroopSubliminal Emotional StroopFace-Word Emotional Stroop.

Eriksen Flanker

A central target flanked by congruent or incongruent distractors; RT and error differences index selective attention and conflict resolution.

Imitation-Inhibition

Execute an instructed finger movement while observing a congruent or incongruent action performed by another person; the congruency effect (faster responses on congruent trials) indexes automatic imitation and the cost of inhibiting observed-action representations.

Implicit Association

Speeded categorization of stimuli belonging to two target concepts and two evaluative attributes using shared response keys; congruence-condition RT difference indexes implicit association.

Navon

Hierarchical letters in which large letters are composed of small ones; RT differences between global and local identification index attentional scope.

Simon

Non-spatial feature (e.g. color) dictates a left/right response while task-irrelevant stimulus location varies; RT cost on incongruent trials indexes spatial response conflict.

Stroop Color-Word

Naming the ink color of color words while ignoring word meaning; RT and error costs on incongruent trials index selective attention and conflict control.

Marked for review

A review mark means the assignment is a judgement call the curator has flagged for a second opinion. On the family an entry is filed under it means “not sure this is the right home”; on a cross-listing it means “not sure this belongs here at all”. The note names the alternative or the doubt. Comments go to the issue tracker.
