在本研究中，事件相关电位被用来阐明进一步的神经签名的积极抑制的（情感）内容的书面文字。通过简单地要求参与者（N= 32）忽略在情感启动（AP）任务中作为启动的单个单词来实现有意抑制。在AP中，关于先验中性目标的评价通常倾向于向先前启动的效价转移，表示AP效应（APE）。为了创造一个合理的覆盖上下文强调词抑制的有用性，参与者被要求避免这种转变，也就是说，作出公正的目标评价。忽略主要词汇被认为是实现这一目标的最有效策略。有效抑制的话的（情感）的内容，建议一个显着的APE目前没有任何进一步的指示，但不为被忽略的话处理，影响多个阶段的处理。在神经元水平上，词抑制的特点是减少早期知觉（左偏词特定N170），后来的注意力（顶叶P300），和情感语义处理（减少后语义不对称）。此外，额外的招聘自上而下的抑制控制过程，这是反映在增加幅度的内侧额叶负性，表现出严重参与故意词抑制。
In the present study event-related potentials were used to shed further light on the neural signatures of active inhibition of the (affective) content of written words. Intentional inhibition was implemented by simply asking participants (N= 32) to ignore single words that served as primes in an affective priming (AP) task. In AP, evaluations about a priori neutral targets typically tend to shift towards the valence of preceding primes, denoting an AP effect (APE). To create a plausible cover-context emphasizing the usefulness of word inhibition, participants were asked to avoid this shift, that is, to make unbiased target evaluations. Ignoring the prime words was suggested as the most efficient strategy to achieve this aim. Effective inhibition of the words’ (affective) content, as suggested by a significant APE present for words processed without any further instruction, but not for ignored ones, affected multiple stages of processing. On the neuronal level, word inhibition was characterized by reduced early perceptual (left-lateralized word-specific N170), later attentional (parietal P300), and affective-semantic processing (reduced posterior semantic asymmetry). Furthermore, an additional recruitment of top-down inhibitory control processes, which was mirrored in increased amplitudes of medial-frontal negativity, showed to be critically involved in intentional word inhibition.
