- Q1How quickly the measure can detect changes in the brain refers to...Temporal ValidityTemporal ResolutionTime AccuracySpatial Resolution30s
- Q2This refers to the smallest measure the scan can detect, how detailed is the information being given.Spatial AwarenessTemporal ValiditySpatial ValiditySpatial Resolution30s
- Q3Machine can you not move with, or it will alter the image?Post MortemFMRIPETEEG30s
- Q4FMRI's work by picking up on the following in your brain...OxygenBlood FlowNeural ActivityElectrical Signal30s
- Q5This machine can produce a 3D image of a brainFMRIERPCameraPost Mortem30s
- Q6Why can ERPs detect more causation than the other methods?Standardised ProceduresElectrodes are more sensitiveExperimental condition & statistical analysisMore electrodes are used30s
- Q7This method of measuring the brain has high spatial resolution but low temporal resolutionERPFMRIEEGPost Mortem30s
- Q8This method of measuring the brain has low spatial resolution but high temporal resolutionEEGFMRIPost MortemERP30s
- Q9What method doesn't get considered why talking about Temporal and Spatial Resolution?Post MortemsFMRIPETEEG30s
- Q10How do ERPs differ from EEGs?ppts are dead when their brain is measuredPpts are measured during a particular state, like sleepPpts are exposed to a stimulus multiple timesDifferent type of electrodes are used30s
- Q11Why do EEG's have low spatial resolution?Each electrode picks up on thousands of neuronal activityThey detect waves rather than specific locationAll 3 answersThe can't detect how deep in the brain the electrical activity has happened30s
- Q12Why can we not establish causation with post mortems?We do not know if the cause of death/ decaying of death caused the brain structureAll 3 answersWe cannot see the central parts of the brainWe can see the brain in action30s
