General Anxiety - Identify and Distinguish Symptom Presentation Gist
- “Free-floating”anxiety
- Excessive anxiety & worry under most circumstances
- Difficult to control worry (a lot of disorders are going to be difficult to control)

- > 6 months (most disorders will have a time frame)
- 3 or more
- Restlessness
- Fatigue
- Difficulty concentrating
- Irritability
- Muscle tension
- Sleep disturbance
- 3 or more
- Usually begins in childhood or adolescence
- A mental disorder marked by constant worry about nondangerous situations and physical symptoms of tension
- GAD caused by stimulus generalization
- Responses to one stimulus are also elicited by similar stimuli (ex: in car accident, scared of cars (phobia), but then realize cars are everywhere; afraid now of trucks, buses, etc; start walking to school, but then you see at school that there are cars at school too, and you start to fear school; just get scared of generally everything
Probably don’t need to know?
- Poverty (less resources, fewer healthcare, less control, less ability to protect ourselves)
- Higher crime rates
- Fewer educational and job opportunities
- Greater risk for health problems
- Gender:
- 2:1 ratio, women
- Comorbidity, women: depression (women more likely to be comorbid with internal disorder)
- Comorbidity, men: substance abuse (men more likely to be comorbid with external disorder)
- 20% of Americans suffer from anxiety disorders, compared to 14.4% of Austrailians
- Why? Different lifestyles; why epidemiology is important
Specific Phobia - Identify and Distinguish Symptom Presentation Gist
- Persistent and unreasonable fears of particular objects, activities, or situations
- Object almost always produces immediate anxiety

- Causes clinical distress
- Most common: specific animals or insects, heights, enclosed spaces, thunderstorms, and blood
- A mental disorder marked by panic attacks surrounding, and avoidance of, objects and situations other than those involving social interaction and/or performance of others
What causes specific phobias?
- First onset triggered by
- Experiencing trauma (bad, life threatening experiences with these objects)
- Direct observation of trauma (watch it or see somebody go through it and get hurt by objects)
- Media coverage of trauma
- Panic attacks (attack so distressful and don’t want that to happen again, you avoid objects that were around you when you had attack)
- Conditioning & Modeling
- Once fears are acquired → avoid object → fear enhanced & maintained
- GAD caused by stimulus generalization
- Responses to one stimulus are also elicited by similar stimuli (ex: in car accident, scared of cars (phobia), but then realize cars are everywhere; afraid now of trucks, buses, etc; start walking to school, but then you see at school that there are cars at school too, and you start to fear school; just get scared of generally everything
-“Preparedness”: an evolutionary explanation (we’re afraid of things that can potentially kill us/hurt us; biologically, genetically prepared to be afraid of certain things because they were dangerous in the past, they survived because of fear and avoidance of snakes; passed down to you; ex: grandma and grandpa afraid of snakes, avoided them, and survived to have kids, while other couple didn’t make it because not afraid and died by getting close to one)
Social Anxiety - Identify and Distinguish Symptom Presentation Gist
- Fear about one or more social situations person is exposed to (person develops idea that something is wrong with them, like feeling unpopular, go into social encounter thinking that, heart rate goes up, sweating, go to encounter person/people, everyone is noticing everything that’s wrong with them, sweating even more, and after, think of all indicators that people were finding everything wrong with them, and this creates a horrible model for the next time)
- Fear you will show anxiety & be judged in social situations
- Social situations avoided or endured
- Fear out of proportion to threat
- > 6 months
- Clinical distress
- Often kept secret, highly disruptive
- 3:2, women; Poverty: 50% more likely

- 2:1, women
- Poverty → 50% more likely

How does Roger’s humanistic perspective understand the cause and treatment of anxiety?
-Lack of “unconditional positive regard” in childhood leads to “conditions of worth” → I am good IF I do or don’t do “x”
- The less overlap between self-image and ideal-self = bad
- Self-image is different to ideal self
- Here self-actualization will be difficult
- More overlap between self-image and ideal-self = good
- Self-image is similar to ideal self
- This person can self-actualize
- Person-Centered Approach (growth promoting climate) - triangular shape
- Congruence (authenticity and realness) at top
- Unconditional positive regard (non-judgemental respect) to right
- Empathy (process of understanding) to left
How are the Amygdala and GABA associated with anxiety.
- Amygdala:
- Anxiety response
- Septal-hippocampal system
- Memory association triggers anxiety
- In normal fear reactions:
- Key neurons fire → excitability
- Brain then tries to reduce excitability
- GABA released to inhibit neuron firing
- Gad linked to:
- Too few GABA receptors
- Ineffective GABA receptors
- Benzodiazepines (valium, xanax) enhance GABA – increase GABA to reduce cortisol (anxiety)
What is the most common antianxiety drug? How does it work? What is its biggest side effect?

- Mix badly with certain other drugs (especially alcohol)
- Biggest side-effect - drowsiness, sleepiness
- Early 1950s = barbiturates (hypnotics)
- More recently = antidepressant and antipsychotic drugs
