Q

What are the two steps in the development of an anxiety disorder in Mowrer’s two-factor model?

A
  1. through classical conditioning - CS is paired with UCS (intrinsically aversive stimulus)
  2. through operant conditioning - avoiding CS is maintained because it is reinforcing (reduces fear)

Q

What are some criticisms of Mowrer’s early version of the two-factor model?

A
  • many people who have anxiety disorders cannot remember any exposure to a threatening event that triggered their symptoms
  • many people who experience serious threats do not develop anxiety disorders
31
Q

What are three different ways in which classical conditioning can occur, according to an extension of Mowrer’r two-factor model?

A
  1. direct experience (dog bites you)
  2. modeling (see a dog bite someone)
  3. verbal instruction (hear about dangerous dogs)
32
Q

What is a neutral predictable unpredictable (NPU) threat task?

A

a laboratory task designed to test sensitivity to unpredictable vs predictable threats

33
Q

What are the three conditions of an NPU threat task?

A
  1. a neutral condition in which they do not experience an aversive stimulus
  2. a predictable condition in which they experience an aversive stimulus and receive a warning beforehand
  3. an unpredictable condition in which they experience an aversive stimulus w/o prior warning
34
Q

What factors distinguish individuals with anxiety disorders from those without?

A

people with anxiety disorders are:

  1. more easily conditioned to fear stimuli
  2. to sustain conditioned fears longer
  3. to respond more strongly to unpredictable, uncertain threats
35
Q

What is the heritability estimate for anxiety disorders?

A

.5 to .6

36
Q

What is the fear circuit?

A

a set of brain structures, including the amygdala, that tend to be activated when the individual is feeling anxious or fearful; especially active among people with anxiety disorders

37
Q

What is the medial prefrontal cortex?

A

a region of the cortex in the anterior frontal lobes involved in executive function and emotion regulation that is implicated in mood and anxiety disorders (fear)

38
Q

Which neurotransmitters are implicated in anxiety disorders?

A

serotonin, GABA, norepinephrine (sensitivity of norepinephrine receptors)

39
Q

What is behavioral inhibition?

A

the tendency to exhibit anxiety or to freeze when facing threat

40
Q

Which anxiety disorder is behavioral inhibition a particularly strong predictor of?

A

social anxiety disorder

41
Q

What are four important cognitive factors in anxiety disorders?

A
  1. sustained negative beliefs about the future
  2. a perceived lack of control
  3. over attention to signs of threat
  4. intolerance of uncertainty
42
Q

What are safety behaviors?

A

behaviors used to avoid experiencing anxiety in feared situations (ex: tendency of people w/ social phobia to avoid looking at other people)

43
Q

What did the Little Albert study show?

A

that intense fears could be conditioned (Little Albert was conditioned to fear a white rat after associating a loud noise w/it)

44
Q

What is a problem with the behavioral model of the etiology of anxiety disorders?

A

not sure if people remember/had a conditioning experience or not; and many people who did don’t develop a phobia

45
Q

What is prepared learning?

A

a biological predisposition to associate evolutionary-relevant stimuli (such as dangerous animals) readily with unconditioned stimuli

46
Q

What are some examples of safety behaviors in social anxiety disorder?

A

avoiding eye contact, disengaging from conversation, standing apart from others

47
Q

How can cognitive processes intensify social anxiety?

A
  1. people w/ SAD appear to have unrealistically harsh views of their social behavior, and overly negative beliefs about the consequences of their social behaviors
  2. attend more to how they are doing in social situations
48
Q

What is the brain region in the fear circuit that is especially important in panic disorder?

A

locus coeruleus (major source of norepinephrine in the brain)

49
Q

What is interoceptive conditioning?

A

classical conditioning of panic attacks in response to internal bodily sensations of arousal - after the first panic attack, the person is classically conditioned to fear somatic symptoms

50
Q

How does the cognitive perspective on panic disorder work?

A

panic attacks develop when a person interprets bodily sensations as signs of impending doom (ex: interpret increase in HR
as sign of heart attack)

51
Q

What is the Anxiety Sensitivity Index?

A

a test that measures the extent to which people respond fearfully to their bodily sensations; predicts the degree to which unexplained physiological arousal leads to panic attacks

52
Q

What is the fear-of-fear hypothesis?

A

a cognitive model for the etiology of agoraphobia; suggests the condition is driven by negative thoughts about the consequences of having a panic attack in public

53
Q

How does generalized anxiety disorder differ from other anxiety disorders?

A
  • people w/ GAD more likely to experience episodes of MDD

- WORRY: decreases volatility of emotion in contrast to other anxiety disorders

54
Q

What is the contrast avoidance model?

A

the theory that chronic worry of GAD provides a functional advantage in reducing the volatility of negative emotions and arousal in response to severe stress

55
Q

What is the common focus of all effective psychological treatments for anxiety disorders?

A

exposure: people must face what they deem too terrifying to face

56
Q

What is an exposure heirarchy?

A

a graded list of the difficulty of someone’s triggers

57
Q

What are two key principles in protecting against relapse with CBT?

A
  1. exposure should include as many features of the feared object as possible
  2. exposure should be conducted in as many different contexts as possible
58
Q

What does the behavioral view of exposure therapy state?

A

works by extinguishing the fear response

59
Q

What does the cognitive view of exposure therapy state?

A

works by helping people correct their mistaken beliefs that they are unable to cope w/ the stimulus

60
Q

What is exposure?

A

real-life (in vivo) or imaginal confrontation of a feared object or situation, especially as a component of systematic desensitization

61
Q

What is the significance of David Clark’s version of cognitive therapy?

A

helps w/ social anxiety disorder so that people learn not to focus their attention internally and combat negative images of how others will react to them

62
Q

How does CBT for panic disorder work?

A

therapist persuades client to deliberately elicit bodily sensations associated w/ panic - patient learns to stop seeing physical sensations as harmful

63
Q

What does the psychodynamic treatment for panic disorder involve?

A

24 sessions focused on identifying emotions and meanings surrounding panic attacks

64
Q

How does CBT for agoraphobia work?

A

systematic exposure to feared situations - ex: gradually tackling leaving home, staying in public places (can be enhanced by including partners)

65
Q

What is the most widely used behavioral technique for treatment of GAD?

A

relaxation training to promote calmness

66
Q

What are anxiolytics?

A

minor tranquilizers or benzodiazepines used to treat anxiety disorders

67
Q

What are the two medications most commonly used for treatment of anxiety disorders?

A
  1. benzodiazepines (Valium, Xanax)

2. antidepressants (SSRIs, SNRIs, tricyclic antidepressants)

68
Q

What are benzodiazepines?

A

any of several drugs commonly used to treat anxiety, such as Valium and Xanax

69
Q

What is buspirone (BuSpar) used for?

A

general anxiety disorder

70
Q

Why are antidepressants often preferred over benzodiazepines?

A
  • people may experience severe withdrawal symptoms when they try to stop using benzodiazepines (can be addictive)
  • benzodiazepines can have significant cognitive and motor side effects (memory lapses, drowsiness)
  • benzodiazepines related to increase risk of car accidents
71
Q

Which medications are considered first-choice treatments in anxiety disorders?

A

SSRIs and SNRIs

72
Q

Why are psychological treatments considered the preferred treatment of most anxiety disorders (except GAD)?

A

because most people relapse once they stop taking medications

73
Q
