Nubuck is a leather conditioning product and can be easily found at stores which carry shoes and handbags. Nubuck products can be ordered on Ebay as well as from online shopping sites.

There is no "fear conditioning"; rather, fear can become a conditioned response via Classical conditioning (Pavlov) or Operant Conditioning (B.F. Skinner).

I can't live without air conditioning in the summer.

Another name for Operant Conditioning is instrumental conditioning.
