Rumination is closely related to mental disorders and can thus be used as a marker of their presence or a predictor of their development. The presence of masking and fabrication in psychological selection can lead to inaccurate detection of psychological disorders. Human language is considered crucial in eliciting specific conscious activities, and the use of natural language processing (NLP) in the development of questionnaires for psychological tests has the potential to elicit immersive ruminative thinking, leading to changes in neural activity. Electroencephalography (EEG) is commonly used to detect and record neural activity in the human brain and is sensitive to changes in brain activity. In this study, we used NLP to develop a questionnaire to induce ruminative thinking and then recorded the EEG signals in response to the questionnaire. The behavioral results revealed that ruminators exhibited higher arousal rates and longer reaction times, specifically in response to the ruminative items of the questionnaire. The EEG results showed no significant difference between the ruminators and the control group during the resting state; however, a significant alteration in the coherence of the entire brain of the ruminators existed while they were answering the ruminative items. No differences were found in the control participants while answering the two items. These behavioral and EEG results indicate that the questionnaire elicited immersive ruminative thinking, specifically in the ruminators. Therefore, the questionnaire designed using NLP is capable of eliciting ruminative thinking in ruminators, offering a promising approach for the early detection of mental disorders in psychological selection.
反刍与精神障碍密切相关，因此可作为精神障碍存在的标志或其发展的预测指标。心理选拔中存在的掩饰和编造可能导致心理障碍的检测不准确。人类语言在引发特定的意识活动方面被认为至关重要，在心理测试问卷的开发中使用自然语言处理（NLP）有可能引发沉浸式的反刍思维，从而导致神经活动的变化。脑电图（EEG）通常用于检测和记录人类大脑中的神经活动，并且对大脑活动的变化很敏感。在本研究中，我们使用NLP开发了一份问卷以诱导反刍思维，然后记录对该问卷的脑电图信号。行为结果显示，反刍者表现出更高的唤醒率和更长的反应时间，特别是在回答问卷中的反刍项目时。脑电图结果表明，在静息状态下，反刍者与对照组之间没有显著差异；然而，在反刍者回答反刍项目时，其全脑连贯性存在显著改变。在回答这两个项目时，对照组参与者没有发现差异。这些行为和脑电图结果表明，该问卷引发了沉浸式的反刍思维，特别是在反刍者中。因此，使用NLP设计的问卷能够在反刍者中引发反刍思维，为心理选拔中精神障碍的早期检测提供了一种有前景的方法。
