The Stroop effect is considered as a standard attentional measure to study conflict resolution in humans. The response of the brain to conflict is supposed to change over time and it is impaired in certain pathological conditions. Neuropsychological Stroop test measures have been complemented with electroencephalography (EEG) techniques to evaluate the mechanisms in the brain that underlie conflict resolution from the age of 20 to 70. To study the changes in EEG activity during life, we recruited a large sample of healthy subjects of different ages that included 90 healthy individuals, divided by age into decade intervals, which performed the Stroop test while recording a 14 channel EEG. The results highlighted an interaction between age and stimulus that was focused on the prefrontal (Alpha and Theta band) and Occipital (Alpha band) areas. We concluded that behavioural Stroop interference is directly influenced by opposing Alpha and Theta activity and evolves across the decades of life.
斯特鲁普效应被视为研究人类冲突解决的一种标准注意力测量方法。大脑对冲突的反应应该会随时间变化，并且在某些病理状况下会受损。神经心理学斯特鲁普测试方法已通过脑电图（EEG）技术得到补充，以评估20至70岁人群大脑中冲突解决背后的机制。为了研究一生中EEG活动的变化，我们招募了大量不同年龄段的健康受试者样本，其中包括90名健康个体，按年龄分为十年间隔组，这些受试者在进行斯特鲁普测试时记录14通道EEG。结果突出显示了年龄与刺激之间的一种相互作用，这种相互作用集中在前额叶（阿尔法和西塔波段）和枕叶（阿尔法波段）区域。我们得出结论，行为上的斯特鲁普干扰直接受到相反的阿尔法和西塔活动的影响，并且在几十年的生命过程中不断演变。
