Quizplus · Accepted Answer

The P300 response is an event-related potential (ERP) that is associated with attention allocation and cognitive processing. When a suspect is guilty, they should show a larger P300 response when crime-relevant events and details are presented compared to noncrime-relevant events. This is because guilty suspects are more likely to have a heightened emotional and cognitive response to crime-relevant stimuli. Therefore, the P300 response is a useful measure for detecting deception in ERP-based lie detection tests.
