• ERP's are more specific than EEG's, bringing more detail to the brain's activity. They have excellent temporal resolution meaning ERP's are frequently used in cognitive research.
• Reseach has been able to identify many different types of ERP and describe the precise role of these in cognitive functioning.
• Critict have poined to a lack of standardisation in ERP methodology between different research studies which makes it difficult to confirm findings.
• Lack of standardisation makes it difficuly to confirm findings in studies involving ERP's. Extraneous variables including background noise must be completely eliminated which is not always easy to achieve.
• Allows researchers to link brainwaves (ERP’s) to specific behaviour
• This way of measuring brain activity is advantageous as it enables determination of how processing is affected by a specific experimental manipulation. This makes ERPs a more experimentally robust method as it can eliminate extraneous neutral activity, something that other scanning techniques may struggle to do.
