I am reading paper-listed below-that talks about three terms, Conditioned freezing; Shock sensitization to startle; Conditioned fear potentiation to startle.
I understand that conditioned freezing takes place when the subject (rat) learns to associate a neutral stimulus (CS) with an aversive stimulus (US), such that when the CS is presented alone, the subject will freeze in the form of defensive behavior. However, I do not understand its relation to the other two terms listed above.
