Lecture 7: Acquisition of Fear
Anxiety disorders:

 Very common;
 1/14 people worldwide affected.

Focus this lecture: early learning experiences.

History and basics of conditioning
Ivan Pavlov: classical conditioning.

 Aspects:
o Neutral stimulus (NS);
 Lead to OR.
o Orientation response (OR);
o Unconditioned stimulus (US);
 Leads to UR.
o Unconditioned response (UR);
 CS + US -> UR.
o Conditioned stimulus (CS);
 Leads to CR.
o Conditioned response (CR).

John B. Watson: fear comes from learning experiences.

 Contrast to existing view that fear is innate.
 ‘Little Albert’ study: loud noise (US) which the baby feared (UR) whenever baby began to play
(OR) with white rat (NS). This way, they trained the infant to fear (CR) the rat (CS).
o Illustrates Pavlovian (classical) conditioning.
o Generalization to other animals and objects.

Fear response (UR) shifts from aversive stimulus (US) to previously neutral stimulus (CS).

 Original view: CS – CR association;

,  Contemporary view: CS – US association.

Deconditioning (Mary Jones): ‘Little Peter’ – counter-conditioning study.

 Associative learning can also lead to unlearning of conditioned response.

Why does fear persist as CS is “harmless”?

 Two-process model (O.H. Mowrer):
o Fear acquisition: classical conditioning;
o Maintenance of fear: operant conditioning.
 Avoidance of feared object (CS) -> decrease fear -> increase in avoidance
behaviour.
 Prevents someone from learning that fear for CS is unfounded, and
so fear persists.

Fear conditioning in the lab
Animal research:

 Sound (CS) -> electric shock (US).
 CR: freezing.

Human research:

 Spider (CS) -> electric shock (US).
 CR: two ways of meauring.
o Subjective: US expectation;
o Physiological: startle response, skin conductance.
 Differential fear response: CS- used as control condition, then
compared to CS+.
o CS+ for 8 seconds, then US (shock);
o Startle probe right before US, height of anticipation (fear) to
US.
o CS- for 8 seconds, startle probe after 7 seconds, no US.
o After conditioning: US-expectancy higher for CS+ than for CS-.
 Indicative of fear learning.
o After conditioning: startle response stronger to CS+ than for CS-, and NA.
 Indicative of fear learning.
 Noise alone (NA) used to see if CS- is truly at baseline.

 Spider in hand is CS-.
