Q

what pattern is seen in anxiety and performance

A

State anxiety more detrimental than trait anxiety (Eysenck, 1982).
• Worry more damaging than emotionality (Morris et al, 1981).
• State anxiety most detrimental in certain tasks (difficult, short-term memory tasks, dual tasks; (Eysenck, 1997).

Q

what is state anxiety and what does it do

A

Anxiety can interfere with functioning and negatively impact performance on tasks

State anxiety - how anxious your feeling in the moment impacts performance more than trait anxiety especially for tasks that require effort and attention

Q

why is state anxiety detrimental in certain tasks

A

State anxiety is more detrimental in certain tasks since worry is using up our attentional resources so its taking our attention away from engaging in other tasks like memory

Q

what is the emotional stroop task

A

State anxiety impacts performance
Trait anxiety and anxiety disorders do appear to show a reliable effect on attention
This has been demonstrated by emotional strop task
Word naming automatic response - hard to suppress - original

Emotional stroop task - test cognitive theories of emotional disorders
Threat related words are printed in different colours participants are asked to name the colour of the words
Compared to neutral words trait anxious and anxierty disorder patients show greater interference with threat related words

Q

what are the results of the dot probe task

A

Dot Probe Task
• Word pairs (threat and non-threat), follow by a dot probe in
the same position as one of them. Trait- anxious and anxious patient’s focus on threat word (e.g., MacLeod & Mathews, 1988).

Anxious individuals move their attention to the threat word and are faster to name the threatening word than the non threatening word as their attention is already focused on identifying threat

28
Q

what is homophone spelling

A
  • Homophone Spelling
  • Listen to words with 2 alternative meanings
  • (e.g. die; dye, tease; teas, slay; sleigh).
  • Trait -anxious write threatening word (Eysenck, MacLeod & Mathews, 1987).
29
Q

what is the processing stage theory of anxiety to explain bias

A

Williams et al (1988). Processing stage theory: anxiety affects automatic processing leading to bias

Unclear whether bottom up or top down - isn’t clear on if anxiety is automatic or strategic
Bottom-up process anxiety is seen as low level out of conscious awareness and is hardwired or highly learned
attention may be a consequence - top down - part of coping

30
Q

what is the hypervigilance theory of anxiety to explain bias

A

Eysenck (1992). Hypervigilance theory:Trait anxious scan environment for threat excessively and lock onto it

31
Q

what is the S-REF theory of anxiety to explain bias

A

Wells & Matthews (1994). S-REF theory: Anxiety associated with activation of Cognitive Attentional Syndrome (CAS) involving self-focus, worry, monitoring for threat and ironic
coping responses (bias is a consequence of coping strategy)
bias is a consequence of threat monitoring

32

  • Ego-dystonic (disgusting/abhorrent)

80% of people have ego-dystonic thoughts which are also called normal obsessions
Normal obsessions aren’t much different to pathological obsessions what is different is how people interpret and deal with these thoughts
Experienced by the individual as disgusting or abhorrent

45
Q

what are compulsions?

A

• Overt or covert action
• Aim is to decrease distress
ex. Washing checking
Compulsions can lead to significant interference with life as often very time consuming

46
Q

what is BDD

A

Body dysmorphia - anxiety in ones appearance - may thing head or ears are too big even when in a normal range

47
Q

what is trichotillomania

A

hair pulling

48
Q

what is excoriation

A

skin picking

49
Q

what are the trauma and stress disorders in the DSM 5

A
  • Reactive attachment disorder
  • Disinhibited social engagement disorder
  • PTSD
  • ASD
  • Adjustment disorders
  • Other specified trauma and stressor disorder
  • Unspecified trauma and stressor disorder
50
Q

what is PTSD

A

PTSD - occur after trauma
Complex ptsd - multiple traumas and abuse
Delayed onset ptsd - develop months or even years after trauma exposure e.g. 9/11 individuals experienced acute stress which then decreased after a number of years when they were reminded of the trauma then then went on to develop post-traumatic stress disorder

51
Q

what is acute stress disorder

A

Acute stress disorder
Often occurs within 4 weeks of being exposed to a trauma
Can have memory difficulties, increased arousal, sleepiness
Normal response which usually decreases within 4 weeks
When these difficulties tend to persist a diagnosis of ptsd may be warranted
It’s this persistence that marks a normal vs maladaptive response

52
Q

what is social anxiety disorder (SAD)

A

Fear of performance or social situations in which person is subject to scrutiny
• Exposure almost invariably causes anxiety
• The situation is avoided or endured with intense anxiety/distress
• Common symptoms: sweating, shaking, blushing, blank mind, fear of humiliation

Bias in cognitive processes can be formulated
SAD -common anxiety disorder associated with other issues such as substance abuse, mood disturbance and difficulty in social interaction

Stop from getting on with life, relationships and it’s also associated with depression, suicidality and substance misuse

53
Q

what are the clinical models of SAD

A
  • Social Skill deficit (little support)

* Cognitive-behavioural factors (Clark & Wells, 1995):

54
Q

the clinical model of Social Skill deficit has little evidence

A

Individuals with social anxiety are deemed to have a lack of social skills like conversation skills or assertiveness
Little evidence - doesn’t explain the way social anxiety presented e.g. specific forms of social anxiety involve fear of using a telephone or eating while being observed but the individual doesn’t lack a skill to do this
Early treatment trained people in social skills and while this did work it was due to exposure not increasing skills , instead the psychological data directs us towards looking at cognitive factors such as bias and attention and behavioural factors

55
Q

cognitive-behavioural factors as a model of SAD

A

• Coping responses and cognitive processes not deficits are central to anxiety maintenance

Model draws on becks schemas theory and the cognitive model
Social anxiety is maintained by individual coping strategies and cognitive processes

56
Q

clark and wells model - why doesnt social anxiety self correct
what are the 5 factors responsible for maintaining social anxiety disorder and resulting in disorder?

A
  1. Self-focused attention
  2. Processing of inner image
  3. Safety behaviours & avoidance
  4. Anticipatory processing
  5. The post mortem
57
Q

what is one of the recommended models for treating testing social anxiety disored in NICE guidelines

A

the Clark and Wells model

58
Q

what are the stages in the clark and wells model

look at slide 12 for placement

A 
social situation
activates assumption
percieved social danger - negative automatic thoughts
processing self as a social object
safety behaviours
somatic & cognitive symptoms
59
Q

what does the clark and wells model assume

A

assume person with social anxiety has underlying beliefs or assumptions about the social world
distinguishes between situation and vulnerability factors

60
Q

what happen in anticipatory processing and post mortem

A

Varying maintenance mechanisms that are keeping the patient experiencing anxiety
Anticipatory processing - social anxiety patients will worry and anticipate danger for hours or days before entering the social situation
Failure and anxiety starts before situation therefore the bias processing has already started which leads to difficulty in having an experience that challenges the negativity

Post mortem - when the anxious person leaves the social situation the anxiety continues and they go over the situation again and again and ruminate and overanalyse the performance - too busy for using on threat and themselves that they only remember their inner image e..g how did I look , what did i say reinforces the negative image even if it went well from an observer perspective the positive experience can be neutralised due to the post mortem and the cognitive rumination that bias and cognition that maintains anxiety

61
Q

what are presence and effect of mechanisms

A

safety behaviours and inner image

62
Q

conclusions from lecture

A

Anxiety is multi faceted we can usefully distinguish normal and pathological norms of anxiety
Anxiety itself can be broken down into sub components with the word component being particularly relevant in understanding behaviour and performance
High anxiety is associated with cognitive biases and such biases have been explored and used to develop an understanding and more effective treatments of anxiety such as social anxiety disorder

63
Q

what is worry

A

a cognitive avoidance response to percieved threat

64
Q

what is rumination in depression

A

difficult to control repetitive thoughts concerning personal problems
focusing on fact one is depresed

65
Q

worry and rumination are linked to

A

increased blood pressure and cortisol levels

lower heart rate variability
