One who induced drooling with unfinished dessert (6)
I believe the answer is:
pavlov
'one who induced drooling with unfinished dessert' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for pavlov that I've seen before include "Russian neurophysiologist, famous for his work with dogs" , "Russian who famously observed conditioned responses in dogs" , "Russian psychologist" , "Russian investigator of conditioned reflexes" , "Famous Russian scientist who studied conditioned reflexes in dogs" .)
