一组可分离的区域被激活，用于与克服优势反应倾向和任务切换相关的执行加工。与克服优生优育有关的区域主要是正面的，可能是参与自上而下偏见以减少冲突的系统的一部分。后脑区域被用来在任务之间切换，并可能在重新配置刺激-反应映射方面发挥作用。楔前活动在两种操作中都是常见的，可能反映了由于更困难的任务要求而增加的视觉注意力。
A dissociable set of regions was active for the executive processing associated with overcoming a prepotent response tendency and task switching. Regions associated with overcoming prepotency were primarily frontal and may be part of a system involved in top-down biasing for conflict reduction. Posterior regions were recruited for switching between tasks and likely play a role in reconfiguring stimulus-response mappings. Precuneus activity was common to both manipulations and may reflect increased visual attention due to more difficult task demands.
