Ψ  Three explanations of classical conditioning:

       •  Stimulus substitution - An account of respondent conditioning, no longer widely accepted, stating that the CS becomes a substitute for the US.
 
       •  Contiguity theory - A response that occurs when a stimulus is present will automatically become associated with it.
 
       •  Cognitive perspective - classical conditioning occurs because an organism learns what to expect (is able to predict). Backward conditioning where the UCS occurs before the NS does not work.
