Background

Three well-reproduced findings in the fear conditioning literature are

  1. Spontaneous recovery: increasing time between extinction and test increases responding to the conditioned stimulus (CS).
  2. Reinstatement: after extinction, re-exposure to unconditioned stimulus (US) increases responding to the CS
  3. Renewal: after extinction, returning animal to acquisition context increases responding to the CS
