Abstract

This narrative review explores the phenomenon of inner speech - mental speech without visible articulation - and its implications for cognitive science and clinical practice. Despite its importance, the many neural mechanisms underlying inner speech remain unclear. We propose classifying inner speech into monologic, dialogal, elicited, and spontaneous forms, and discuss related phenomenological and neural correlates theories. A literature review on PubMed (1990-2024) identified 83 studies. Dialogal forms recruit Theory of Mind networks, compared to monologic forms. Task-elicited inner speech activates the left inferior frontal gyrus more strongly, while spontaneous inner speech engages Heschl's gyrus, suggesting auditory involvement. Evidence regarding aphasia suggests inner speech may be partially preserved even when overt speech is impaired, offering a potential route for rehabilitation. Future research should also address the emotional aspects of inner speech, its role in psychopathology, and its developmental trajectory. Such studies may improve interventions for disorders related to dysfunctional inner speech.Abbreviation: ACC: anterior cingulate cortex; ALE: activation likelihood estimation; AVH: auditory verbal hallucination; BMI: brain-machine interface; CD: corollary discharge; ConDialInt: consciousness-dialogue-intentionality; DES: descriptive experience sampling; DTI: diffusion tensor imaging; dPMC: dorsal premotor cortex; dmPFC: dorsomedial prefrontal cortex; IFG: inferior frontal gyrus; M1: primary motor cortex; MedFG: medial frontal gyrus; MFG: middle frontal gyrus; MTG: middle temporal gyrus; MRI: magnetic resonance imaging; preSMA: presupplementary motor area; PrG: precentral gyrus; SMA: supplementary motor area; SMG: supramarginal gyrus; SPC: superior parietal cortex; SPL: superior parietal lobule; STG: superior temporal gyrus; STS: superior temporal sulcus; TVA: temporal vocal areas; ToM: theory of mind; vmPFC: ventromedial prefrontal cortex.

内在言语的多面性:现象学、神经关联、失语症和精神病理学的含义。
这篇叙述性综述探讨了内在言语现象——没有可见发音的心理言语——及其对认知科学和临床实践的影响。尽管它很重要,但内部言语背后的许多神经机制仍不清楚。我们建议将内在言语分为独白、对话、引出和自发形式,并讨论了相关的现象学和神经相关理论。PubMed(1990-2024)的文献综述确定了83项研究。与单一形式相比,对话形式需要心理理论网络。任务诱发的内部言语更强烈地激活了左侧额下回,而自发的内部言语则激活了颞下回,表明听觉参与其中。有关失语症的证据表明,即使外在语言受损,内部语言也可能部分保留下来,这为康复提供了一条潜在的途径。未来的研究还应该关注内在言语的情感方面,它在精神病理学中的作用,以及它的发展轨迹。这些研究可能会改善对与功能失调的内在语言相关的障碍的干预。缩写:ACC:前扣带皮层;ALE:激活似然估计;AVH:听觉言语幻觉;BMI:脑机接口;CD:必然放电;ConDialInt: consciousness-dialogue-intentionality;DES:描述性经验抽样;DTI:扩散张量成像;dPMC:背侧运动前皮层;dmPFC:前额叶背内侧皮层;IFG:额下回;M1:初级运动皮层;MedFG:内侧额回;MFG:额中回;MTG:颞中回;MRI:磁共振成像;preSMA:预辅助运动区;PrG:中央前回;SMA:辅助运动区;SMG:边缘上回;SPC:顶叶上皮层;SPL:顶叶上小叶;STG:颞上回;STS:颞上沟;TVA:颞声乐区;汤姆:心理理论;vmPFC:腹内侧前额皮质。
