Q

evaluate behaviourist explanation for phobias

A

S
little albert, sue et al, Ost 1987
C
diathesis-stress- not everyone is situation gets phobia, reductionist-not everyone has story
O
cognitive- irrational thoughts, biological preparedness- ancient fears- Seligman
U
practical applications e.g. CBT
T
lab- reliable

26
Q

behavioural treatment for phobias

A

behaviour is learnt so can be unlearnt
classical conditioning removes phobias via counter conditioning where you learn a new response

27
Q

systematic desensitisation

A

Joseph Wolpe 1958
counterconditioning and reciprocal inhibition (cant be scared and relaxed at same time)
1) relaxation techniques
2) anxiety hierarchy
3) gradual exposure until calm at top of hierarchy and no longer associate stimulus with fear

28
Q

flooding

A

1 long session where exposed to phobia at its worst whilst practicing relaxation techniques
without avoidance, person quickly learns phobic stimulus is harmless
fear response has time limit- adrenaline levels naturally decrease and new stimulus- response link learned

29
Q

what is it called when a phobia is no longer present?

A

extinct

30
Q

evaluate behavioural treatments for phobias

A

S
craske et al-both equally effective, choy et al, mcgrath, **gilroy-spider phobia experiment **
C
flooding- traumatic- ethical issues
SD- time consuming and expensive
dont get to root cause so other phobias may still be there/ replaced- individ diff
O
CBT better for phobias w cognitive aspects eg social
ohman et al- evolutionary survival component
anxiety drugs if not in contact w fear often eg flying
U
cure people- economic benefits
T
lab- reliable, controlled

31
Q

what is depression?

A

mood disorder
prolonged and fundamental disturbance of mood and emotion
most common psychopathological disorder- 5% of adults

32

A

5 of following and persistent low mood for 2 weeks:
increased or decreased appetite
increased or decreased sleep
less energy
body slows/ speeds
less interest in usual activities
feeling guilty
cant concentrate
thoughts of death

shift in activity level, affected sleep, affected appetite, aggression/ SH

34
Q

emotional characteristics of depression

A

low mood, low self esteem, loss of interest, anger at others and self

35
Q

cognitive characteristics of depression

A

negative thoughts, negative view of the world, poor concentration, dwell on negatives, absolutist feelings

36
Q

Aaron beck’s negative triad (1967)

A

negative schema from childhood so adopt - view of the world
three parts to cognitive vulnerability to depression
1) faulty info processing
2) - self schema
3) negative triad
focus on - and get trapped in cycle, self fulfilling prophecy
- view of world > - view of future > - view of self >

37
Q

Ellis’ ABC model 1962

A

not what happens to someone but how they deal with it
Activating event
Belief (rational/ irrational)
Consequence (rational= positive consequence vice versa)

38
Q

eliss’ mustabatory thinking

A

thinking certain things must be true to be happy
e.g. i must do well
leads to disappointment/ depression

39
Q

evaluate cognitive explanations for depression

A

S
hammen and kranz, bates et al- depressed ppts more depressed when given negative statements
C
suggests its the clients fault, reductionist (alloy and abrahamson), abc is incomplete as doesnt explain when no activating event, problem with causality
O
biological (genes/neurotransmitters/drugs work/ Zhand et al serotonin), diathesis stress
U
CBT is most effective treatment
T
inference- cant see thought processes- low validity
reliable- lab

40
Q

how does CBT work?

A

changes thinking by challenging irrational/ maladaptive thoughts
leads to change in behaviour

41
Q

Ellis’ rational emotional behavioural therapy

A

Ellis is one of first psychologists to develop form of CBT
beliefs people hold lead to self defeating consequences so REBT replaces irrational thoughts with rational ones

42
Q

Ellis’ ABCDEF model

A

D- disrupting irrational thoughts/beliefs
E- effects of disputing and effective attitude to life
F- feelings produced

43
Q

Steps of CBT

A

1) challenging irrational thoughts- replacing w + to lead to + consequences
2)HW assignments- challenge beliefs between sessions and prove wrong
3) behavioural activation- encouraged to do things they enjoy e.g sport naturally lifts mood
4) unconditional positive regard- convince client of own self worth and oppose thoughts, tell them they’re worthy

44
Q

evaluate cognitive treatments for depression

A

S
ellis 1957, cuijpers et al 2013- CBT found to be best treatment for depression, Babyak et al 2000, Rosenzweig 1936, dodo bird effect
C
ellis 2001-not always efective as some dont put beliefs into action, alkin et al 1985, simons et al 1995, suicidal patients need immediate help
O
antidepressants- less effort cuijpers et al said good in conjunction w CBT
U
people get back to what they enjoy and work, better mood and consequences, long term to help cope w depression
T
drug trials, lab experiments- reliable, eco valid

45
Q

what is OCD?

A

anxiety disorder where a person experiences intrusive obsessions followed by compulsions

46
Q

what is the internal component of OCD?

A

obsessions
persistent and uncontrollable thoughts/images/worries/doubts. intrusive and unwanted. often realise theyre irrational but can only get rid of them by performing compulsions

47
Q

what is the external component of OCD?

A

compulsions
repetitive physical behaviours/ metal rituals performed over and over to relieve the anxiety of obsessions. temporary and reinforces obsessions so cycle worsens

48
Q

what is the cycle of OCD?

A

obsessive thought
anxiety
compulsive behaviour
temporary relief

49
Q

cognitive characteristics of OCD

A

obsessions
eg ideas, doubts, impulses, images
uncontrollable and anxiety provoking
may know that theyre irrational

50
Q

behavioural characteristics of OCD

A

compulsions
eg handwashing, checking, counting
attempt to decrease anxiety
avoidance of the thing that triggers anxiety

51
Q

emotional characteristics of OCD

A

anxiety, embarrassment, shame, low mood (OCD often has depression alongside), guilt, disgust

52
Q

what is a candidate gene? 2 examples for OCD

A

gene believed to be related to a particular trait
not certain you will have disorder but predisposed
COMT, SERT

53
Q

how does a mutated COMT gene lead to OCD?

A

COMT gene instructs body to produce COMT enzyme which clears synapses of neurotransmitters that havent been uptaken
Tuken et al 2013 found mutated COMT leads to less activity so less enzymes so dopamine levels increase
dopanine has been associated with compulsions in OCD and affects preforntal cortex so harder to control actions

54
Q

how does a mutated SERT gene lead to OCD?

A

mutated SERT results in more transporter proteins on the presynaptic neuron so serotonin is reuptaken faster leading to lower levels of serotonin
high levels of SERT are found in patients with OCD

55
Q

neural explanations for OCD?

A

1) abnormal levels of neurotransmitters (not about genes)
2) caudate nucleus (in basal ganglia), orbitofrontal cortex and thalamus are involved with worry circuit. OFC goes on high alert if something is worrying and sends signal to thalamus. minor worries should be intercepted by caudate nucleus which prevents thalamus from being over excited. if caudate nucleus damaged (by abnormal neurotransmitter levels), cant surpress minor signals so worry circuit.

56
Q

evaluate biological explanations for OCD

A

S
netadt et all (2000), billet et al (1998)-MZ twins 2x more likely to get disorder if twin haas it than dz, menzies et al (2007), pauls and leckman (1986), rasmusses and eisen (1992)
C
not 100% concordance rates for mz- not just genes
drugs dont always work-not just neurotransmitters
O
slt, behaviourism (2 process model), cognitive, diathesis- stress
U
**embryo screening, gene therapy, easier to understand (reductionist), improved diagnostics, lead to discoveries of drug treatments **
T
brain scans- reliable

57
Q

how do SSRIs work?
side effects?

A

blocks transporter proteins to prevent reuptake of serotonin so levels increase
most common drug for OCD

nausea, headaches, insomnia

58
Q

how do tricyclics work?
side effects?

A

block serotonin AND noradrenaline transporter proteins so less reuptaken so levels increase

more side effects so prescribed if other dont work
cardiovascular problems and heart attack, increased heart rate, hallucinations

59
Q

how do benzodiazepines work?
side effects?

A

slow down CNS by enhancing activity of neurotransmitter GABBA which binds to channel proteins so increases flow of cl- into neuron. when taking BZ, it also binds to GABBA receptor sites resulting in channel protein opening more frequently so more cl- go into neuron so - charge and harder for neuron to be stimulated so less activity and individuals feel more relaxed

aggression, long term impairment of memory, addiction

60
Q

evaluate biological treatments for OCD

A

S
soomro et al (2008)- more effective than placebo but only tested short term
partial decrease in symptoms for 40-60% of patients
C
side effects
publication bias- turner et al (2008)
moderately effective- might not work for everyone, individual differences
O
CBT long term, root cause, drugs just mask symptoms so relapse when stop
U
help people feel better/ working-econo
easy, cheap (but add up as constantly sue), effective, immediately available, little input from patient
T
drug trials- reliable
