We designed a semi-structured questionnaire for the introspective evaluation of inner experience of participants undergoing functional magnetic resonance imaging (fMRI) in the resting state. This resting state questionnaire (ReSQ) consists of 62 items organized by five main types of mental activity: visual mental imagery (IMAG); inner language (LANG), split into two subtypes, inner speech (SPEE) and auditory mental imagery (AUDI); somatosensory awareness (SOMA); inner musical experience (MUSI); and mental manipulation of numbers (NUMB). For IMAG and LANG, additional questions estimated association of such activities with ongoing learning, retrospective memories, or prospective thoughts. Using a 0-100% scale, the participant quantitatively rated the proportion of time spent in each mental activity during the resting state fMRI acquisition. A total of 180 healthy volunteers completed the ReSQ immediately after being scanned with fMRI while at rest. Of these, 66% exhibited dominance of a type of mental activity at rest (IMAG: 35%; LANG: 17%; SOMA: 7%; MUSI: 6%; NUMB: 1%). A majority of participants reported either retrospective memories (82%) or prospective thoughts (78%), with 58% of participants reporting both in at least one type of mental activity. Thoughts related to ongoing learning were low (37% of participants). The present results are consistent with those of previous studies investigating inner experience in a natural environment. In conclusion, we provide a robust and easy-to-implement tool for the exploration of mental activities during rest of healthy participants undergoing fMRI. This tool relies on normative data acquired from a 180-participant sample balanced for sex and handedness.
我们设计了一份半结构化问卷，用于对接受功能磁共振成像（fMRI）静息状态的参与者的内在体验进行内省评估。这个静息状态问卷（ReSQ）由 62 个项目组成，分为五种主要的心理活动类型：视觉心理意象（IMAG）；内言语（LANG），分为内部言语（SPEE）和听觉心理意象（AUDI）两种亚型；躯体感觉意识（SOMA）；内在音乐体验（MUSI）；和数字的心理操作（NUMB）。对于 IMAG 和 LANG，额外的问题估计了这些活动与正在进行的学习、回溯记忆或前瞻性思维的关联。参与者使用 0-100%的量表，定量评估在 fMRI 静息状态采集期间每个心理活动所花费的时间比例。共有 180 名健康志愿者在完成 fMRI 扫描后立即完成了 ReSQ，他们在静息时处于休息状态。其中，66%的人在休息时表现出一种心理活动的主导地位（IMAG：35%；LANG：17%；SOMA：7%；MUSI：6%；NUMB：1%）。大多数参与者报告了回溯记忆（82%）或前瞻性思维（78%），其中 58%的参与者在至少一种心理活动中报告了这两种情况。与正在进行的学习相关的思维较少（37%的参与者）。目前的结果与之前在自然环境中研究内在体验的研究结果一致。总之，我们提供了一种强大且易于实施的工具，用于探索接受 fMRI 的健康参与者在休息时的心理活动。该工具依赖于从 180 名参与者样本中获得的、平衡了性别和利手的规范数据。
