Q

describe the study showing acquisition of a phobia through classical conditioning

A

Little Albert
-had no unusual anxiety to a white rat
-when the neutral stimulus of a white rat was paired with the unconditioned stimulus of a loud noise, the unconditioned response of fear from the loud noise was associated with the neutral stimulus of a white rat and now the white rat produces a conditioned response
of fear and anxiety

Q

describe how phobias are maintained

A

by operant conditioning

-when our behaviour is reinforced (reward or punishment)

  • reinforcement increased frequency of behaviour
  • when you avoid an unpleasant situation (negative reinforcement) and as a result get a desirable consequence (of not being in presence of phobic stimulus) the behaviour will be repeated (positive reinforcement)

Q

Describe systematic desensitisation as a treatment of phobias

A
  • is a gradual process
  • attempts to counter-condition the learned response of anxiety to a response of relaxation through classical conditioning
  • if relaxation is associated with the phobic stimulus this will prevent the response of anxiety (reciprocal inhibition)

Q

Describe the main 3 steps of systematic desensitisation

A
  • anxiety hierarchy - rank different situations from lowest to highest level of anxiety
  • relaxation - client is taught relaxation techniques (e.g. meditation, breathing exercises, visualisation)
  • exposure - over several sessions the client will be exposed to situations that create increasing anxiety levels based on the hierarchy, only move on if relaxed at that level

23
Q

Describe the process of flooding

A
  • by being exposed to the phobic stimulus without the option of avoidance behaviour the client learns the stimulus is harmless
  • sometimes the response stops due to exhaustion as adrenaline has a limit and so fear can’t be maintained and so the stimulus has to be associated with relaxation

Use of EXTINCTION
- the learned response of fear is extinguished when the conditioned stimulus (e.g. dogs) is present without the unconditioned response (e.g. biting you) and so the conditioned stimulus no longer produces the conditioned response of fear

Q

Behavioural characteristics of depression

A
  • activity levels - anything requires more effort, leisure activities less enjoyable
  • disruption to sleep and eating - insomnia (can’t sleep) and hypersomnia (too much sleep)
  • aggression and self harm - take out anger on close ones or direct it to yourself
27
Q

Cognitive characteristics of depression

A
  • poor concentration - difficulty sticking to task, procrastinate, easily distracted
  • dwelling on negative - cognitive bias towards negatives and unhappy moments
  • absolutist thinking - black or white, something goes slightly wrong it’s a disaster
28
Q

Ellis’ Cognitive explanation to depression

A

• Ellis’ ABC model -
rational thinking = good mental health
irrational thoughts = mental health conditions

ACTIVATING EVENT
- irrational thoughts triggered from negative experience

BELIEFS
- irrational beliefs (musturbation, i-can’t-stand-it-itis, Utopianism)

CONSEQUENCES
- irrational beliefs cause emotional and behavioural consequences

29
Q

define irrational thoughts

A

any thoughts that intefere with us being happy and free from pain

30
Q

describe all of Ellis’ identified irrational beliefs

A
  • musturbation = must always succeed
  • i-can’t-stand-it-itis = something going slightly wrong is a major disaster
  • Utopianism = life should always be fair
31
Q

Describe Becks cognitive approach to explaining depression

A

Becks Theory

  • some people are more vulnerable to depression than others due to their cognitions
  • cognitive vulnerability has 3 parts:
  • Faulty information processing - focus on negatives, something goes wrong it’s a disaster (absolutist thinking)
  • Negative self-schema - interpret information about ourselves in a negative way

• Negative Triad - 3 elements that lead to someone developing a dysfunctional view of themselves
—> negative view of world - no hope, not fair
—> negative view of self - worthless, low self esteem
—> negative view of future

32
Q

State the cognitive approaches to treating to depression

A

•Cognitive Behaviour therapy

  • Ellis’s Rational Emotive Behaviour Therapy - form of CBT
  • Beck’s cognitive therapy - form of CBT
  • Behavioural activation - part of CBT
33
Q

Describe cognitive behaviour therapy as a treatment to depression

A
  • use of cognitive and behavioural techniques
    COGNITIVE- assessment where client identifies goals and any negative or irrational thoughts
    BEHAVIOURAL - challenge their negative and irrational thoughts and replace them with more positive effective behaviours
34
Q

Describe Ellis’ Rational Emotive Behaviour Therapy as a treatment to depression

A

• REBT - a form of CBT
- added D and E to his ABC model
DISPUTE
- central technique is identifying and challenging the irrational thoughts (vigorous argument) and so the irrational thoughts can be altered

EFFECT
- break the link between negative thoughts and events and depression by challenging the negativity

36
Q

Describe Beck’s Cognitive Therapy as a treatment to depression

A
  • identify thoughts about world, self and future (negative triad)
  • main component of therapy is to challenge these thoughts
  • also test the reality of clients negative beliefs by setting homework where they have to record events of positivity
37
Q

methods of vigorous argument

A

empirical argument - dispute whether there is actual evidence to support the negative beliefs

logical argument - dispute whether the negative belief is logical based on the evidence

39
Q

Define reciprocal inhibition

A

person cannot show anxiety and relaxation at the same time

40
Q

Weaknesses of the cognitive approach to explaining depression

1 Becks Theory

1 Ellis ABC Model

A

Ellis’ Theory
•doesn’t explain some types of depression (endogenous depression)
-some depression can occur without the stage ‘A’ (activating event)

Becks Theory
•partial explanation
- some aspects are not explained (e.g. why some people feel immense anger or experience hallucinations and delusions)

41
Q

Strengths of the cognitive approach to explaining depression

1 Becks Theory

1 Ellis ABC Model

A

Ellis’ ABC Model
•real world application into cognitive treatment
-REBT has been shown to change negative beliefs and relieve symptoms of depression
-REBT is based on ABC model

Beck’s Theory
•supporting evidence from Cohen
-tracked and continually measured cognitive vulnerability in 473 adolescents
-found that cognitive vulnerability 
predicted later depression
42
Q

Describe behavioural activation as a treatment to depression

A

-part of CBT where negative behaviours are gradually decreased (like isolation and avoidance) and positive behaviours are gradually increased (like socialising, exercise)

43
Q

Define OCD

> Define obsessions

> Define compulsions

A

•obsessive-compulsive disorder
- a condition that involves obsessions and compulsive behaviour

  • obsessions - intrusive thoughts that recurr
  • compulsions - urge to repeat a behaviour
44
Q

Behavioural characteristics of OCD

A

The behavioural aspect of OCD is compulsive behaviour
•the compulsive behaviour is:
> repeated - person feels compelled to repeat the behaviour

> anxiety reducing - reduce anxiety caused by obsessive thoughts

> avoiding - avoidance of situations where there may be triggers that cause anxiety

45
Q

Emotional characteristics of OCD

A
  • anxiety and distress - anxiety in obsessive thoughts as they are unpleasant and overwhelming
  • depression - often OCD patients experience low moods and lack of enjoyment in activities
  • guilt and disgust - irrational, out of promotion guilt for minor issues (e.g. massive guilt for being late)
46
Q

Two biological explanations to OCD

A

Genetic explanations

Neural explanations

47
Q

Describe the Genetic explanation to OCD

A

Genes can lead to OCD vulnerability

Diathesis-stress model

Candidate genes

OCD is polygenic

There are different types of OCD

48
Q

Describe research showing genes can lead to OCD vulnerability

A

Lewis
•37% of his patients had OCD, 21% of their siblings had OCD
not 100% so it is a vulnerability to OCD that runs in families

49
Q

Describe the diathesis-stress model

A

-suggests people can have a genetic vulnerability for OCD that can be triggered by environment, experiences or stress

50
Q

Describe candidate genes in relation to vulnerability to OCD

A

•Candidate genes have been identified by researchers as genes that create vulnerability for OCD
-some of these genes are involved in regulating serotonin levels

51
Q

Explain the idea that OCD is polygenic and research showing it

A
  • means that OCD is not caused by one single gene but a combination of genetic variations
  • these combine to form vulnerability to OCD

TAYLOR found evidence of 230 genes linked with OCD
-including genes associated with the neurotransmitters serotonin and dopamine (these regulate mood)

52
Q

Describe the idea that there are different types of OCD

A

The origin (aetiology) of OCD leads to different causes (heterogenous)

  • one variation of groups of genes may cause a different types of OCD in one person than in another
  • the genetic combination leading to OCD changes from person to person
53
Q

Define aetiologically heterogeneous

A 
The origin (aetiology) of OCD leads to different causes
(heterogenous)
54
Q

Describe the neural explanations to OCD

A
  • the role of serotonin

- abnormal functioning of decision making part of brain

55
Q

Describe the role of serotonin in causing OCD

A
  • the neurotransmitter serotonin controls mood
  • neurotransmitters are responsible for relaying info from one neurone to another
  • if someone has low serotonin levels than the transmission of mood-related info doesn’t take place
  • therefore they will experience low moods
56
Q

Cognitive characteristics of OCD

A
  • obsessive thoughts - recurring thoughts
  • cognitive coping strategies - mental coping strategies to deal with the anxiety of the obsessions (e.g. meditating), may appear abnormal and can prevent them from completing everyday activities
  • knowledge of their excessive anxiety - aware their compulsions and obsessions aren’t rational
57
Q

Describe the role of the abnormal functioning of the decision making part of the brain in OCD

A
  • some OCD cases are associated with impaired decision making
  • this could be associated with abnormal functioning of the frontal lobes of the brain
  • these are responsible for thinking and making decisions

-also research suggesting the parahippocampal gyrus which is associated with processing unpleasant info, functions abnormally in OCD

58
Q

1 Strengths of genetic explanations to OCD

1 weakness of genetic explanations to OCD

A

STRENGTH
•research support
- Nestadt’s found that 68% of identical twins share OCD compared to 31% of non identical twins
-support that genetics increases vulnerability to OCD

WEAKNESS
•partial explanation to OCD
-doesn’t account for environmental risk factors that can trigger or increase risk of developing OCD
-Cromer et al found that over half of the OCD clients in her sample had experienced a traumatic event in their life

59
Q

Describe the biological approach to treating OCD

A

DRUG THERAPY:
>SSRIs

> Combining other treatment and SSRIs

> Alternatives to SSRIs

60
Q

Describe what SSRIs are and how they work

A

Selective Serotonin Reuptake Inhibitors

  • SSRIs inhibit reuptake
    —>where excess serotonin is transported out of synaptic cleft by transporters
  • prevents serotonin being transported back which leaves higher serotonin levels in the synaptic cleft
  • means the serotonin can continue stimulating the post synaptic neurone with mood-related information
61
Q

Describe the combination of SSRI with other treatments

A
  • often combined with Cognitive Behaviour Therapy
  • the drugs reduces emotional symptoms
  • this means people can engage more effectively with the CBT
62
Q

Describe the alternatives to SSRIs

A

When SSRIs are not effective other drugs can be used
Some alternative drugs work for some and not at all for others

  • Tricyclics- acts on various systems including serotonin system (which it has same effect on)
  • SNRIs- (serotonin, noradrenaline reuptake inhibitors) increase serotonin and noradrenaline levels
63
Q

1 Strengths of neural explanations to OCD

1 weakness of neural explanations to OCD

A

STRENGTH
•research support
-research on antidepressants that work on serotonin levels, have shown that they are effective in reducing OCD symptoms
-suggests serotonin is involved in OCD

WEAKNESS

  • serotonin levels being disrupted may not be a direct link to OCD
  • many people with OCD also have clinical depression (co-morbidity)
  • depression usually occurs due to disruption to levels of serotonin
  • could be that serotonin is disrupted in OCD clients because they are already disrupted due to their depression
64
Q

Strengths of biological approach to treating OCD

A

•a practical treatment

  • cost effective - tablets manufactured in bulk at reasonably low prices
  • time effective- thousands of tablets and doses can be manufactured in same time as one therapy session

•research showing the effectiveness of SSRIs

  • Soomro reviewed 17 studies comparing SSRIs to placebos in OCD treatment and found all 17 provided better outcomes
  • reduced symptoms by 70%
65
Q

Weaknesses of biological approach to treating OCD

A

•minority suffer from side effects

  • indigestion, blurred vision
  • 1 in 10 suffer from weight gain or erection problems
  • overall reduce quality of life
  • these people may be scared to try future drug treatment so they become completely ineffective

•publication bias of drug effectiveness
-some psychologists believe evidence for drug effectiveness is biased
-because psychologists are sponsored by drug companies they may choose to publish only positive outcomes of the drug use
—> publication bias

66
Q

Describe the cycle of OCD

A
  • obsessive thought
    —> anxiety
    —> compulsive behaviour
    —> temporary relief
