Electroencephalogram (EEG) and Event
related potentials (ERPS) Questions With
Solutions
What is Event related potentials? (2) What is left when all extraneous brain activity from
an EEG recording is filtered out
Types of brainwaves that are triggered by particular events
How is the EEG filtered out to leave the ERPs? Statistical analysis
2 strengths of ERPS - 1 usefulness + 1 effectiveness 1) More specific measurement of
neural processes that cant be explained by raw EEG data
2) High temporal resolution
1 weakness of ERPS Lack of standardisation of process
How does EEG measure electrical activity in the brain Via electrodes that are fixed to an
individual's scalp using a skull cap
