In fear conditioning studies, an initially neutral stimulus is repeatedly paired with an aversive one, borrowing from classical conditioning.

If a neutral stimulus is frequently presented along with the unconditional stimulus, it becomes a " conditional stimulus " ( CS ).

If a neutral stimulus is frequently presented along with the unconditioned stimulus, it becomes a " conditioned stimulus " ( CS ).

In addition, lab experiments generally require very brief ( less than a second ) intervals between a neutral stimulus and an unconditioned stimulus.
15.
Once an association is formed between the neutral stimulus and aversive event, a startle response is observed each time the neutral stimulus is presented.

Each fish was then presented with a neutral stimulus of a light that went on 10 seconds before the net plunged into the water.

Pairing a neutral stimulus, for example a bell ( conditioned stimulus ) with food caused the bell to elicit salivation ( conditioned response ).

Conditioned fear is the framework used to explain the behavior produced when an originally neutral stimulus is consistently paired with a stimulus that evokes fear.

Similarly, fear-conditioning is the acquisition of knowledge that informs an individual that a particular neutral stimulus now predicts an event that endangers their psychological or physical well-being.
