对干扰的控制是认知生活的一个普遍特征。干扰控制研究的核心是确定其潜在机制。研究集中在过滤掉分散注意力的知觉信息，导致负启动的过程，以及丢弃导致主动干扰的侵入记忆的过程。关于情景提取过程中是否存在一个单一的过程，即负启动过程和前摄干扰的消解过程，存在着不同的理论。使用功能性磁共振成像，我们将这两种现象结合到一个单一的范例中，发现枕叶皮层的激活与负启动唯一相关，而左侧前额叶皮层的激活增加与主动干扰唯一相关。这种结果模式与依赖于单一过程来解释这两种现象的理论相矛盾。然而，研究结果也表明，共同招聘的右背外侧前额叶皮层和顶叶区域，因此表明，一些控制过程是共享的。
Control over interference is a pervasive feature of cognitive life. Central to research on interference control has been the identification of its underlying mechanisms. Investigations have focused on processes that filter out distracting perceptual information, leading to negative priming, and processes that discard intruding memories that cause proactive interference. Theories differ regarding whether or not a single process during episodic retrieval underlies both negative priming and the resolution of proactive interference. Using functional magnetic resonance imaging, we combined both phenomena into a single paradigm and found that occipital cortex shows activation uniquely related to negative priming, whereas activation increases in left lateral prefrontal cortex are uniquely associated with proactive interference. This pattern of results contradicts theories that rely on a single process to account for both phenomena. However, results also showed common recruitment of right dorsolateral prefrontal cortex and parietal regions and therefore suggest that some control processes are shared.
