Event-related potentials typically can be extracted by doing which of the following?
A)Taking a blood sample
B)Looking at the power of different frequency bands during a task
C)Averaging over many repetitions of the same cognitive activity
D)Brain surgery to remove the ERPs
E)Injecting a tracer

Question

Quizplus · Accepted Answer

Event-related potentials (ERPs) are extracted by averaging over many repetitions of the same cognitive activity. This allows for the identification of the time-locked electrical activity in the brain that is associated with a specific cognitive process or stimulus. ERPs are not extracted through blood samples, frequency band analysis, brain surgery, or tracer injections.
