investigating the brain eval

Question 1

strengths of fMRI

Answer 1

• no reliance on radiation
• non-invasive
• high-spatial resolution
• can be replicated often
• participants more likely to use - wider sample

Question 2

weaknesses of fMRI

Answer 2

• low temporal resolution
• expensive
• only measures blood flow
• weakened validity - correlates data (blood flow) to activities

Question 3

strengths of EEG

Answer 3

• can aid in diagnosis - epilepsy
• provides wealth of knowledge for sleep cycle
• very high temporal resolution
  (1 millisecond)

Question 4

weaknesses of EEG

Answer 4

• easily generalised - lacks specificity
• researchers cannot identify where specific brain activity originates from - low spatial resolution

Question 5

ERP strengths

Answer 5

• specific - stats avg
• high temporal resolution
• useful for cognitive neuroscience

Question 6

ERP weaknesses

Answer 6

• lack of methodological standardisation
• demanding - very controlled environment

Question 7

post mortem strengths

Answer 7

• aided Broca - Wernicke understanding
• improved upon rudimentary knowledge

Question 8

weaknesses of post mortem

Answer 8

• issues with correlational links / non causal links
• data isn’t generalisable - post mortem subjects = inherently damaged brain
• lack of consent? ethics
