public transport, open spaces, enclosed spaces, crowds or lines and leaving home alone
how many types of situations are required for agoraphobia?
at least 2 of the 5
what is the fear-of-fear hypothesis?
agoraphobia may involve fear of having a panic attack in public, rather than the fear of public places themselves
what is kayak-angst?
a culture specific panic condition among inuit seal hunters alone at sea, involving intense fear, disorientation and fear of drowning
what biological factors are linked to panic disorder?
family and twin findings suggest genetic risk. some physical conditions can also cause panic like symptoms
what does the noradrenergic theory of panic propose?
excessive activity in the noradrenergic system may contribute to panic attacks
how does GABA generally affect noradrenergic activity?
GABA generally inhibits or reduces noradrenergic activity
what is anxiety sensitivity?
fear of anxiety symptoms because they are believed to be dangerous or harmful
what is generalized anxiety disorder (GAD)?
persistant, excessive, difficult-to-control worry across many areas of life
4 features of GAD
difficulty concentrating, fatigue, restlessness, irritability and muscle tension
what can contribute to the onset of GAD?
stressful life events, psychological processes, and possible biological or genetic factors
how do learning theories explain GAD?
anxiety becomes conditioned to a broad range of external stimuli
what role does perceived control play in anxiety?
a lack of perceived control can contribute to anxiety
what is intolerance of uncertainty?
difficulty coping with unpredictable or ambiguous situations, which can increase worry
predictable events produces less anxiety than unpredictable events do
what is approach-avoidance conflict in GAD?
wanting certainty while avoiding anxiety. which creates a conflict that can increase worry
how can worry negatively reinforce GAD?
worry may distract from negative emotions and block emotional processing, helping maintain anxiety
what are positive metacognitive beliefs about worry?
beliefs that worrying is useful, such as believing it helps solve problems
what are negative metacognitive beliefs about worry?
beliefs that worrying is dangerous and uncontrollable
what biological findings are linked to GAD?
possible genetic influences, increased dorsal amygdala activation and involvement of the GABA system
how does psychoanalytic theory explain GAD?
unconscious conflict produces anxiety without the person knowing its source

what are barbiturates?
an early class of anxiety medications with high addiction and potentially fatal overdose risk
what is benzodiazepines?

side effects can include nausea, dizziness, drowsiness, memory problems and dependence with some medications
