Document Summary
Cognitive neuroscience methods used to examine cognitive control. Cognitive control (top-down: ability to orchestrate thought and action in accordance with internal goals, conscious internal goals take precedence over automatic processes, exhibited in inhibitory control, selective attention and impulse control. Cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them. Egner and hirsch (2005) what is the mechanism of control regions? fmri study presented participants with congruent and incongruent face-name stimuli (stroop- like task) Face stimuli elicit bold responses in the ffa: using face stimuli -> test whether better cognitive control performance was associated with amplified processing of faces (target), suppressed processing of faces (distractor) or both. When faces are the target, higher cognitive control performance was associated with increased activity in the ffa when compared to low control trials. When faces are the distractor, control performance is not associated with the level of.
