Task Difficulty Modulates Brain Activation in the Emotional Oddball Task

Highlights • Increasing task difficulty attenuates brain activation for emotional distractors. • Target-related brain activation increases with task difficulty. • Emotional distractors increase subsequent activation for difficult targets. • Emotion-target interactions in brain activation covary with...
