1
Q

What do cognitive psychologists often investigate, how and why is this used?

A
  • Internal mental processes
  • Using inferences
  • Direct observation of cognitive processes is not possible + behaviour is influenced by thoughts

Q

Results of Bartlett (1932) study:

A

–> All English pps reconstructed story to recall it better:
- Included elements of English culture
- ‘ghosts’ detail left out
- Order of story changed to be more logical
- ‘Canoes’ changed to ‘cars’
- ‘Bows’ changed to ‘guns’
–> Pps remembered less info as more time passed between reading and recalling story

Q

Evaluation of genetics: (+3, -2)

A

+ Helps to locate genes on chromosomes
+ Uses twin studies –> useful as concordance rates can be examined to relate to behaviour
+ People can be screened to check if they are carrying genes for specific illness
- Reductionist –> reduces complex behaviour like IQ into just small components like genes
- Ignored other models eg cognitive, where someone who develops depression may not carry the gene but rather have faulty cognitions

Q

Natural selection process:

A

1) Genetic makeup of an individual can undergo a random mutation

Q

Findings of Buss (1989):

A
  • Females desired males with good financial prospects, resources and ambition
  • Males desired females w/ reproductive value and those who were youthful and younger than them
38
Q

Evaluation of Buss (1989): (+1, -2)

A

+ Cross cultural validity
- Does not consider social and cultural perspectives that may affect partner choice eg Western cultures value slim body shape, whereas some Eastern cultures prefer larger body shapes
- Lacks temporal validity

39
Q

Which researcher said that Buss (1989) lacks temporal validity and why?

A
  • Buller (2005)
  • Most women today are independent and have their own resources hence do not rely on a mate
40
Q

2 main biological structures:

A

1) Nervous system
2) Brain

41
Q

What 2 sub-systems does the nervous system consist of and it’s features?

A
  • Central Nervous System –> brain and spinal cord, controls breathing and heart rate
  • Peripheral Nervous System –> sends and receives messages from CNS to other parts of body
42
Q

What are the four lobes of the brain and what is the function of each?

A
  • Parietal –> dealing with and reacting to environment
  • Frontal –> emotional control like personality
  • Temporal –> language and memory
  • Occipital –> important for vision
43
Q

Evaluation of biological structures: (+1, -3)

A

+ Relies on use of scans, which is most scientific
- Explains some but not all behaviours eg phobias are usually learnt
- Cause and effect cannot be established
- Psychologists still don’t have full knowledge of brain and its functions

44
Q

For what reasons might schizophrenia develop and what usually used to investigate this?

A
  • Structural and functional brain abnormalities
  • Post mortems in the past, fMRIs now
45
Q

Which study examined neural correlate changes in schizophrenic patients?

A

Swayze

46
Q

How many schizophrenic patients were examined and what was used to test them?

A

50 schizophrenic patients examined using MRI

47
Q

What structural abnormalities were found?

A
  • Decrease in brain weight
  • Enlarged ventricles filled with water
  • Smaller hypothalamus
  • Less grey matter (intelligence is held here)
  • Abnormalities in pre frontal cortex (personality is held)
48
Q

Evaluation of Swayze:

A

+ Strong supporting evidence that schizophrenia is caused by neural correlate changes in pre-natal development
- Does not explain schizophrenia in adulthood
- Conflicting research evidence
- Cause and effect is not established

49
Q

What are the two pieces of conflicting research evidence?

A

1) Andreason (1982) found extent to which ventricles are enlarged is not that significant, therefore there is very little difference between normal and schizophrenic brain
2) Davison and Neale (2001) showed sufferers of mania also have enlarged ventricles, so it could be a vulnerability factor that increases risk instead of the cause

50
Q

Neurotransmitter:

A

Chemical messengers that communicate via cerebral fluid

51
Q

Evaluation of neurochemistry:

A

+ Can be measured objectively eg. injection of dopamine
+ Knowledge that lack/excess of neurotransmitter has an effect on behaviour
- Cause and effect needs to be established
- Reductionist as complex human behaviour involves more than this
- Criticised by cognitive approach –> it would say behaviour is caused by thought patterns

52
Q

Dopamine hypothesis procedure, results and who did it:

A

Davis and Neale:
1) Drugs like phenothiazines are given to patients that block dopamine in brain, which reduced hallucinations and delusions (positive symptoms) of schizophrenia
2) L-Dopa, LSD, amphetamines increases dopamine levels, which were tested on healthy, non-psychotic people
3) Dopamine metabolism seems to be abnormal

53
Q

Evaluation of dopamine hypothesis:

A

+ Research support to suggest they have high level of dopamine –> Davidson found when L-Dopa was given, schizophrenic symptoms intensified
+ Brain scanning evidence (PET and fMRI) show dopamine is cause
- Cause and effect is unclear
- Dopamine has been associated with other illnesses as well like mania
- Reductionist

54
Q

3 key assumptions of psychodynamic approach:

A

1) Driving force behind our behaviour is the unconscious mind
2) Instinct and drives motivate our behaviour
3) Early childhood is pivotal in making us the person we are

55
Q

How many levels does Freud believe there are to the mind and what are each?

A

A

Process called fixation can occur where child’s later adult personality could show permanent signs reflecting stage at which it happened

87
Q

Oedipus complex (during phallic stage)

A
  • During phallic stage, boys develop incestuous feelings towards their mother and hatred for rival in life, which is their father
  • Out of castration anxiety by father, boys repress feelings for mother and identify w/ father
  • Internalise his gender roles and moral values (his superego)
88
