Noetic consciousness
The sense of knowing something factually — knowing it is true — without re-experiencing it. The counterpart Tulving distinguished from autonoetic consciousness.
Endel Tulving in 1985 proposed three modes of consciousness tied to memory: anoetic (non-knowing, automatic), noetic (knowing), and autonoetic (self-aware re-experiencing). Knowing that Paris is the capital of France is noetic; remembering the trip you took there is autonoetic. Most adult cognition involves both, often together.
SDAM is best described as a severe reduction of autonoetic consciousness with intact noetic consciousness. People with SDAM know the facts of their own lives; what is missing is the layer that normally makes those facts feel re-lived. The distinction matters because it places SDAM as a specific, structured pattern rather than a general memory deficit.
