Some psychologists, however, argue that the distinction between long- and short-term memories is ...

Proprioception

... hot/cold as well. (Note: The work of V. S. Ramachandran indicates that despite popular belief, the phantom limb phenomena is actually the result of neural signal bleed through the brain's sensory maps, rather than from stimulation of nerves.)
