perseveration, n.All

Perseveration (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a repetition, like Leonardo's doubled "at 7 o'clock" in noting his father's death, that marks hidden affect while draining the entry of emotion.

Perseveration (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the persisting of a psychic process after others have replaced it in consciousness; it flourishes in the vacuum of consciousness left by distracted attention, and strongly feeling-toned ideas tend to perseverate.
