Cognitive-Behavioural Processes Flashcards
FORMULATION APPROACH: COGNITIVE-BEHAVIOURAL PROCESSES
- occur on formulation-based dimensional approach normality-severe continuum
KUYKEN ET AL (2005) - case-formulation (CBT cornerstone) draws on theory to describe presenting issues
- develops hypotheses/associated frameworks to develop treatment
IDIOGRAPHIC
- focus on individual/presenting symptoms
- hypothesises cause/effect
- precise treatment tailoring
FORMULATION-BASED APPROACH
- dimensional approach
- recognises processes/disorders operating on normality-severe disturbance in gen pop
CATEGORICAL APPROACH
- diagnostic systems tend to use disorder categories to describe those w/psychological disorders
- aim to fit presenting symptoms into disorder category
- qualitative break between those who have a PD/those who don’t
- each disorder = discrete entity from others/normal beh
SOCIAL ANXIETY DISORDER
- 1/5 major anxiety disorders in DSM-5
- overlaps w/APD/common traits ie:
1. shyness
2. negative evaluation fear
SOXIATY ANXIETY DISORDER: CRITERIA
- marked/persistent fear of 1/+ social/performance situations in which person = exposed to unfamiliar people/possible scrutiny (ie. meeting people/public eating/humiliation fear, etc.)
- exposure provokes immediate reaction
- irrational fear = recognised
- feared situation = avoided; interferes w/daily life
TRANSDIAGNOSTIC APPROACH
- focuses on cognition/beh biases across disorders and how processes contribute to disorder maintenance
- short-cuts/heuristic thinking to save time/resources; usually helpful
- ie. large animal growling = dangerous (reasoning) -> run away (behaviour)
- certain short-cuts = characteristic of psychological disorders; contribute to maintenance (causal role)
TRANS APPROACH X PSYCH DISORDERS
- cognition lets us understand personality/psychological disorders/mental illness
- cognitive processes of perceiving/interpreting/planning become distorted in personality disorders
- trans approach has a role to play in personality x psychological disorders overlap via cognition biases
PDs: COGNITION BIASES
- distorted perception of others
- misinterpretation of others’ intentions
- altered social cognitions ie. impaired social judgement
- self-concept distortion ie. lack of stability/low or high self-esteem (narcissism)
COGNITIVE BEH PROCESSES X PSYCH DISORDERS
- particular cognitive beh processes implicated in psych disorder maintenance:
1. attention
2. memory
3. reasoning
SOCIAL PHOBIA: ATTENTIONAL BIASES
- signals of concern hypervigilance (ie. others’ responses to their beh)
- self-focussed attention = ^ internal cue awareness (ie. sweating/trembling); confirms social ineptitude fears
SOCIAL PHOBIA: MEMORY PROCESSES
- selective negative past social event retrieval
- increases anxiety/self-focused attention
SOCIAL PHOBIA: REASONING BIASES
- misinterpretation of situations (before/during/after)
SOCIAL PHOBIA: BEHAVIOURAL BIASES
- avoidance/safety beh prevent disconfirmation of beliefs
- prevents new learning
SELECTIVE ATTENTION
- specific stimuli within external/internal environments selected for further processing
- attentional bias = some people (ie. those w/anxiety disorders) have systematic tendency to attend/avoid particular stimuli class
SELECTIVE ATTENTION: PROCESSES
- evidence indicates most everyday beh triggered/maintained in automatic manner so resources are freed for other actions
AUTOMATIC - eg. distracted by sudden moving object/noise
CONTROLLED - consciously attending to stimulus (ie. someone walking towards you in a street)
SELECTIVE ATTENTION: EXPERIMENTAL PARADIGMS
- researchers developed many for standardised attention measurement
- paradigms provided much info BUT…
- each relies on indirect selective attention measure so misses complexities of IRL situations
ATTENTION BIAS: DETECTION TASKS
- ie. visual search tasks (detection/distraction)
- if individual = prone to attending more to particular stimuli type -> faster detection if located among distractors
CLASSIC STROOP TEST
- YELLOW (red f.), GREEN (black f.), RED (red f.)
- instructions = read aloud colours in which words are printed; ignore content
- compared Reaction Time (RT) when ink colour/name colour = inconsistent VS consistent
- slower to colour name when inconsistent
EMOTIONAL STROOP TEST
- APRIL (light green f.); DEATH (dark green f.); TABLE (red f.)
- instructions = read aloud colour in which words are printed; ignore content
- compare RT when word content = neutral VS disorder related ie. death
EMOTIONAL STROOP TEST: INTERPRETATION DIFFICULTIES
- may induce internal attention ie. reflecting pre-occupation w/themes associated w/emotional word
- may induce emotional reaction that inhibits response -> slow RT
- cognitive avoidance ie. longer RT may reflect suppression attempts of threatening context
DOT PROBE
- selective attention measure indexed by SHORTER response latency -> better/less ambiguous measure
- emotional cue/dot probe (upper/lower) spatial location = balanced across whole task
- faster responses for emotional word VS neutral = indicates selective attention towards emotional info of that nature
EYE TRACKER/VISUAL SCANPATH STUDIES
- other paradigms assess attention indirectly; this is more direct
- directly assesses if people focus gaze over time
- pps = control/schizophrenia/affective disorder
- BUT… we can attend material that we aren’t directly seeing ie. from corner of eye
- disadvantage = cannot measure covert attention to spatial region independent of eye movement
TRANS APPROACH: ATTENTIONAL PROCESSES
HARVEY et al (2004)
- measured attention w/various methods
- 3 attentional processes considered as definitely trans processes:
SELECTIVE ATTENTION
- concern-relevant external stimuli (aka. confirms pre-existing beliefs; interferes w/new info)
- concern-relevant internal stimuli (aka. self-focussed attention)
ATTENTIONAL AVOIDANCE/SAFETY ATTENTION
- prevents habituation/stimuli reappraisal
