- STUDYING THE BRAIN
- EEG
- + safe +diagnosis eg epilepsy +detects stages of sleep, Dement et al +millisecond so very accurate
- - can't see where the neural activity is coming from in the brain
- Measures brainwaves (neural activity) via electrodes placed on the scalp. Detects abornmalities
- fMRI
- + no radiation + high resolution pictures eg for Broca's / Wernicke's area
- - very expensive - only works if the person remains completely still
- Blood(oxygen) rushes to areas of the brain when it's active. fMRI detects oxygenation
- RRP
- looks as the brain's reactions to different stimuli
- + if a person is telling a lie, the ERP will show that the person telling a lie because it will show association through neural activity +millisecond +looks at the cognitive perspective, why individuals react in different ways to different stimuli
- - isn't standardised to results cannot be confirmed
- Post Mortem
- Analysis of the physical brain after death
- + evidence of earlier work eg Broca's area / Wernicke's are + helps further hypothesise biopsychology
- - damage to the brain may be abrnormal because of post death environment eg brain decay - may lack consent from patient
- EEG
