What are the three interrelated anxiety systems activated in response to a perceived threat?
Physical, behavioural and cognitive
How does the physical system respond to anxiety?
Fight/flight response activated by sympathetic nervous system. Mobilises resources to deal with threat. Physical symptoms.
How does the cognitive system respond to anxiety?
Attentional shift and hypervigilance (can't think about anything else)
How does the behavioural system respond to anxiety?
Safest response is to avoid/escape threat.
If you cannot escape, then respond with aggression.
Why are the three systems set up like this?
To keep us alive. Normal anxiety is necessary for survival.
What are specific 'prepared' stimuli?
Things in the environment that we are genetically predisposed to fear because they once posed a threat to us eg insects, animals, heights, enclosed spaces, anger
Threat appraisal --> ______ --> automatically elicits anxiety
Expectancy of harm
It is important to distinguish between the stimulus and the expected harm/outcome. Eg if public transport is the stimulus, what are different possible outcomes?
1. Embarrassment (social anxiety)
2. accident/death (PTSD)
3. germs/illness (OCD)
Expectancy of harm is the product of....
Perceived probability (how likely ppl will stare at me on the bus) and perceived cost (how bad will it be if people stare at me on the bus)

More tendency to perceive threat in ambiguous situations, and a greater anxiety response to the perceived threat
What is the difference between normal and abnormal anxiety?

What causes your anxiety disorder to maintain and get worse?
Why are anxiety disorders highly comorbid with one another and with substance abuse and depression?
Generalised biological vulnerabilities
- genetic loading towards neuroticism
Generalised psychological vulnerabilities
