Chapter 6: Panic, Anxiety, and Their Disorders
Anxiety: uneasiness associated w/ an event that might occur. More general.
Panic: physiologcal aspect and sypmtoms, here and now, measurable, overt
The Fear and Anxiety Response Patterns
Fear or panic is a basic emotion that involves activation of the “fight-or-flight” response
Fear is more pronounced than panic
Lots of anxiety can lead to panic
Fight/flight = evol’nary responses
Different components
Cognitive: feeling within, not actually real
Physiological
Behavioural
Peripheral Nervous System
Peripheral Nervous System
Sympathetic: gets you ready for dangerous situations. Instant reponse.
-One neuron is from CNS form synapse (Ach released) goes to affect the functioning of another neuron (ex. Heart)
then releases NE to activate heart to pump blood faster
Parasympathetic: resting/digesting, takes time to kick in
-Ach is an important NT for both synapses and periphery
-2 neurons, one to neuron
The Fear and Anxiety Response Patterns
Anxiety is a general feeling of apprehension about possible danger
Anxiety is more oriented to the future and more diffuse than fear
(panic/fear = here and now)
It has cognitive/subjective, physiological, and behavioural components
Subjective: very personal
Physiological: ex.stress
Behavioural

PSY240 Lecture 6
Anxiety disorders have unrealistic, irrational fears or anxieties of disabling intensity as their most obvious
manifestation
Rational to the person, but overall don’t make a lot of sense.
If the anxiety is interfering on their everyday life = irrational
Evolutionary preparedness for the development of fears and phobias
When we all feel the same way about something
Many of our fears and anxieties are learned (classical conditioning)
Ex. Young child views father abuse mother at the same time everyday fuels anxiety (classical
conditioning)
The Anxiety Disorders and Their Commonalities
The DSM-IV-TR recognizes seven primary types of anxiety disorders
1. Phobic disorders of the “specific” type
Not general, specific to a situation, but still unrealistic. Public speaking = more scary than death???
IRRATIONAL
2. Phobic disorders of the “social” type
Also can be lumped into dealing w/ other people.
3. Panic disorder with agoraphobia
Agoraphobia= being out in a public space.
Ex. The person might have had a panic disorder in a public place and now they are afraid of being in public.
not necessarily afraid of people.
4. Panic disorder without agoraphobia
Without agoraphobia
5. Generalized anxiety disorder
ex. School, work, parents, siblings, etc.
6. Obsessive Compulsive Disorder
OCD: obsessed w/ doing something repeatedly.
7. Post-Traumatic Stress Disorder
PTSD: lumped under anxiety disorder, b/c associated w/ the future.
If you have a panic disorder, it’s not just thinking about here and now, it’s also about NEXT panic attack.
The Anxiety Disorders and Their Commonalities
There are some important similarities
The basic biological causes of these disorders
The basic psychological causes of these disorders
The effective treatments for these disorders
Phobic Disorders
A phobia is a persistent and disproportionate fear of some specific object or situation that presents little or
no actual danger
The DSM-IV-TR lists three main categories of phobias:
Specific phobia: to an object/situation/person
Social phobia: socially mediated context
Agoraphobia: fear of public places b/c the event happened outside the home.
Phobia: NEED TO KNOW THE DEF’N to be concrete in abnormal psych!**
Anxiety disorder/panic disorder = need to know the distinction!**
Common Specific Phobias
Acrophobia
