what does ERPs do?
A
only measure general brain activity
2
Q
what can ERPs be used for?

want to find out brain activity in response to certain stimuli/ certain task

A
different as they are a response to a stimulus EEG’s are not

A
. sensory
. cognitive
5
Q
what waves do sensory ERPs ‘pick up’?
A
early waves
- first 100 milliseconds of exposure
6
Q
what is the temporal resolution in ERPs?
A
high
7
Q
what waves do cognitive ERPs ‘pick up’ ?
A
later waves
- produced once a individual has had a chance to mentally process the stimulus
