>[!abstract] >Anendophasia is the condition of lacking an inner voice or internal monologue, meaning that a person does not experience the sense of silently "hearing" themselves think in words. Unlike typical inner speech, where individuals narrate, rehearse, or reflect using verbal thought, those with anendophasia may rely more on visual, abstract, or non-linguistic modes of cognition. Though not yet formally recognized in diagnostic manuals, it is discussed in psychology and cognitive science as part of the spectrum of variability in inner experience, alongside phenomena like [[aphantasia]] (lack of visual imagery). >[!references] >- [[Nedergaard & Lupyan, 2024]]: The prevalence of anendophasia in the general population is on the order of 5–10%. Anendophasia has a moderate negative impact on cognitive performance, as people with it adapt using coping strategies (such as voicing out loud what they are trying to figure out or remember). >- [[Lind, 2025]]: Disputes the existence of anendophasia. >[!related] >- **North** (upstream): [[Cognitive psychology]] >- **West** (similar): [[Aphantasia]] (absence of visual imagery) >- **East** (different): — >- **South** (downstream): —
