  • Q1
    How quickly the measure can detect changes in the brain refers to...
    Temporal Validity
    Temporal Resolution
    Time Accuracy
    Spatial Resolution
    30s
  • Q2
    This refers to the smallest measure the scan can detect, how detailed is the information being given.
    Spatial Awareness
    Temporal Validity
    Spatial Validity
    Spatial Resolution
    30s
  • Q3
    Machine can you not move with, or it will alter the image?
    Post Mortem
    FMRI
    PET
    EEG
    30s
  • Q4
    FMRI's work by picking up on the following in your brain...
    Oxygen
    Blood Flow
    Neural Activity
    Electrical Signal
    30s
  • Q5
    This machine can produce a 3D image of a brain
    FMRI
    ERP
    Camera
    Post Mortem
    30s
  • Q6
    Why can ERPs detect more causation than the other methods?
    Standardised Procedures
    Electrodes are more sensitive
    Experimental condition & statistical analysis
    More electrodes are used
    30s
  • Q7
    This method of measuring the brain has high spatial resolution but low temporal resolution
    ERP
    FMRI
    EEG
    Post Mortem
    30s
  • Q8
    This method of measuring the brain has low spatial resolution but high temporal resolution
    EEG
    FMRI
    Post Mortem
    ERP
    30s
  • Q9
    What method doesn't get considered why talking about Temporal and Spatial Resolution?
    Post Mortems
    FMRI
    PET
    EEG
    30s
  • Q10
    How do ERPs differ from EEGs?
    ppts are dead when their brain is measured
    Ppts are measured during a particular state, like sleep
    Ppts are exposed to a stimulus multiple times
    Different type of electrodes are used
    30s
  • Q11
    Why do EEG's have low spatial resolution?
    Each electrode picks up on thousands of neuronal activity
    They detect waves rather than specific location
    All 3 answers
    The can't detect how deep in the brain the electrical activity has happened
    30s
  • Q12
    Why can we not establish causation with post mortems?
    We do not know if the cause of death/ decaying of death caused the brain structure
    All 3 answers
    We cannot see the central parts of the brain
    We can see the brain in action
    30s
