Abnormality - Explanations Flashcards

1
Q

What are the 2 key assumptions of the BIOLOGICAL approach to abnormality?

A
  1. All behaviour, normal and abnormal, is rooted in our biology, in particular our brain
  2. Abnormality is an illness or disease and is often referred to as the medical model

Q

Explain ‘brain damage’ in terms of the BIOLOGICAL explanation to abnormality

A

That the structure of the brain effects behaviour, and once the disease / brain damage has caused mental health, there is little to be done to cure it.

Q

How do adoption studies work?

A

They separate genes and the environment: adopted children who develop mental disorders are compared with biological and adopted parents. Genetic abnormality would expect the adopted child to inherit abnormality from the biological parent, despite not sharing the same environment.

Q

What is an evaluative point about Twin studies?

A

It hard to distinguish between the genetic effect and the environmental effect; the more genetically similar twins are, arguably the more environmentally similar they are.

Define a strong Ego
A well adjusted person who can cope with demands of the ID and Super Ego
26
Define unchecked ID impulses
Where ID impulses might be expressed in a destructive or immoral way
27
Define a too powerful Super Ego
Where the rigidity of the superego might overpower the ID so that the person is deprived of social pleasure
28
Give 3 example of psychological disorders that could be caused by unchecked ID impulses
1. psychopath 2. rapist 3. exhibitionism
29
Give an example of a psychological disorder that could be caused by a too powerful super ego
OCD
30
What are the key experiences of the oral stage in the psychosexual stages of development?
Sucking initially, then as teeth develop, biting. | Breast feeding
31
What are the key experiences of the anal stage in the psychosexual stages of development?
Toilet training; retaining and expelling faeces
32
What is the phallic stage?
Noticing gender differences | Most importantly the Oedipus complex
33
Explain the Oedipus complex
boys proposing their sexual curiosity and close physical contact with their mums leads to intense affection and desire, developing rivalry with their father. Resolved by absorbing his father's moral attitudes, founding the superego.
34
What is the Latency stage?
Focus on social rather than psychosexual development.
35
How are the psychosexual stages related to abnormality?
Abnormality occurs from fixation (failure to resolve one of the stages)
36
How can fixation of the oral stage lead to abnormal behaviour? Give 2 ways
If undergratified at a yound age, fixation can lead to adult habits such as smoking/drinking. Because gratification at the oral stageinvolves complete dependancy for the infant, it can lead to over-dependancy in future relationships
37
How can fixation at the anal stage lead to abnormal behaviour?
If one retained faeces at a young age, it could lead to an obesssion with hygiene and cleanliness / OCD If one expelled faeces a lot at a young age, it could lead to being overly messy later in life.
38
How can fixation at the phallic stage lead to abnormal behaviour?
Could lead to gender identity disorder / homosexuality
39
List 3 defence mechanisms in the PSYCHODYNAMIC approach
1. Projection 2. Denial 3. Displacement
40
Explain Projection as a defence mechanism
When someone's own faults or wishes are attributed to someone else, e.g accusing someone of something that you are actually feeling
41
Explain Denial as a defense mechanism
When someone refuses to believe events or not admitting they are experiencing certain emotions that provoke anxiety
42
Explain Displacement as a defense mechanism
Diverting emotions on to someone else, e.g if someone does bad in a test they might blame their teacher
43
Name 2 pieces of research for the PSYCHODYNAMIC approach to abnormality
1. Massie and Szajnberg | 2. Pate and Gabbard
44
State the procedure and findings of Massie and Szajnberg
Followed the development of 76 people from birth to the age of 30. They assessed quality of parental control and traumatic events. At 30 the mental health of participants was assessed. They found mental health problems were moderately associated with poor parents relationships and strongly associated with traumatic events in childhood
45
State a strength and a weakness of Massie and Szajnberg's study
Strength: Same procedure for all participants - reliable and fair Weakness: The measure of mental health relies on self-report - not a reliable form of measurement.
46
State the procedure and conclusions of Pate and Gabbert's case study
Observed Mr A who they believed to have infantilism. He had been adopted. Supports the psychodynamic model; Freud would have said that Mr A got stuck in a stage resulting in abnormality, or a response to a traumatic childhood.
47
State one weakness of Pate and Gabbard's case study
Data relies on self-analysis; interpretation of what Mr A said in therapy - not reliable data
48
Explain classical conditioning
An unconditioned stimulus results in an unconditionsed response. When the unconditioned stimulus is paired with a neutral stimulus, it still results in a unconditioned response. After conditioning, the conditioned stimuls (originally the neutral stimulus) will lead to the conditioned response (the original response).
49
How is classical conditioning linked to abnormality?
It can be the accquisition of a phobia, e.g associating an object at the place of a traumatic event with fear.
50
Give an example of a case study regarding classical conditioning
Little Albert
51
Explain operant conditioning
Behaviour is influenced by the consequenceds of our actions; if it is positively or negatively re-inforced then it is likely to be repeated, whereas if it is punished then it is likely to stop
52
How is operant conditioning linked to abnormality?
If an abnormal behaviour is positively/negatively re-inforced then the behaviour is likely to persist.
53
Give an example of how operant conditioning can result in abnormal behaviour
If someone acts aggressively towards someone and they succum, then the behaviour has been re-inforced and so is likely to be repeated.
54
What is the social learning theory? (SLT)
Learning through observation/imitation
55
State the procedure and findings of a study for classical conditioning in regards to the BEHAVIOURAL approach
WATSON & RAYNER Little Albert was classically conditioned to be afraid of rats due to associating the rat with a loud noise (inducing fear) despite having no fear of them before
56
State the procedure and findings of a study for the social learning theory in regards to the BEHAVOURIAL approach
Mineka Studied young monkeys where the parents had a fear of snakes (not genetic). The monkeys observed their parents and eventually developed a phobia of snakes.
57
State 2 weaknesses of the BEHAVOURIAL approach
1. Reductionism | 2. Free will
58
What is reductinoism in regards to the BEHAVOURIAL approach?
Reduces abnormal behaviour to very basic explanations and doesn't consider cognitive and emotional contributions.
59
What is free will in regards to the BEHAVOURIAL approach?
It is deterministic as it assumes that if a behaviour is reinforced then it will be repeated ect. But this is not always the case; in reality people are entitled to decide when it is appropriate for them to stop or continue.
60
What is the rationale of the COGNITIVE approach?
Thinking (cognition) processes that occur between a stimulus and response are responsible for the resulting emotion.
61
What are the 3 stages to the COGNITIVE approach?
1. Environmental stimulus 2. Cognitive appraisal 3. Behavourial response
62
Explain the concept of schemata in the COGNITIVE approach
Human behaviour is influenced by schemata, relating to how we see ourselves. Schemata develop on the basis of early experience. Negative schemata leads to negative automatic thoughts
63
What are negative automatic thoughts?
Unconscious and rapid responses to certain situations, leading to the prevention of focussing on the positives.
64
Explain Ellis's ABC model
Activating events (A) are thought of by beliefs (B) which lead to certain consequences (C)
65
State the flow diagram of Ellis's ABC model
A: Activating event B: Rational/Irrational thuoghts C: Desirable/Undesirable emotions Desirable/Undesirable behaviour
66
Give an example of an irrational belief in Ellis's ABC model
'I must do well in my A levels'
67
What is Ellis's model based on?
Irrational thinking
68
What is Beck's theory regarding the COGNITIVE approach based on?
Negative thinking leading to depression
69
Explain errors in logic (Beck's theory)
Drawing illogical conclusions when they evaluate themselves. Overgeneralising situations
70
What are the 3 aspects to the Cognitive Triad (Beck's theory)
Negative views of: 1. The self 2. The world 3. The future
71
State the procedure and findings of a study into the COGNITIVE approach
Lewinsohn et al Compared a group of adolescents who had unrelaistic negative thought patterns with those who did not. A year later the negative thinkers were statistically more likely to have developed clinical depression than the control group.
72
Identify a methodological strength of Lewinsohn's study
High ecological validity due to it being a natural experiment.
73
Identify 1 strength of the COGNITIVE approach to abnormality
Therapy based on the cognitive model can be very effective for anxiety disorders or depression.
74
Identify 3 weaknesses of the COGNITIVE approach to abnormality
1. Schemata concept is vague and lacking detail 2. Depression may cause irrational thinking, not the other way round 3. Doesn't consider the biological approach (e.g seratonin)
75
State weaknesses of the PSYCHODYNAMIC approach
- Lacks scientific evidence - Most evidence is from case studies (hard to generalise) - Impossible to prove and disprove (explanations for everything)
