An electrical response measured relative to a specified event, commonly estimated from repeated scalp recordings. Its timing and distribution constrain processing hypotheses, but scalp averages are not direct recordings from an isolated neural generator. Differences between conditions can overlap in time without demonstrating strictly separate serial stages.

Event-related potentials (ERPs) are measured brain responses that are directly the result of a specific sensory, cognitive, or motor event. They are obtained through electroencephalography (EEG), which records electrical activity in the brain via electrodes placed on the scalp. ERPs reflect the time-locked brain activity following the presentation of a stimulus, such as visual or auditory information, and can be used to study a variety of cognitive processes, including perception, attention, memory, and decision-making.
