Can altered states silence internal dialogue?
Short Answer
Yes, altered states can significantly reduce or temporarily eliminate internal dialogue through changes in brain regions responsible for self-referential thinking and verbal processing.
Why This Matters
This occurs because altered states often suppress activity in the default mode network, particularly areas like the medial prefrontal cortex that generate self-talk and narrative thinking. Reduced activity in language centers like Broca's area also contributes to quieting verbal thought processes. This demonstrates how consciousness can shift from its typical verbal-narrative mode to more direct, non-linguistic awareness states.
Where This Changes
The degree of internal dialogue suppression varies significantly across different altered states and individuals. Some states may only reduce the volume or frequency of self-talk rather than eliminating it entirely.
