A P300 latency below 300 milliseconds is treated as fast, while around 240 milliseconds is near the fastest typically observed. The P300 is an event-related potential that appears about 300 milliseconds after a meaningful or unexpected stimulus. P300 latency reflects the speed of brain signal processing. P300 voltage is interpreted as a marker of available cognitive resources. In an auditory P300 task, a person responds to occasional target high tones among common low tones.
