Question

Quizplus · Accepted Answer

The P1 ERP (event-related potential) is a positive waveform that occurs approximately 50-100ms after stimulus onset in visual processing. It is associated most closely with the direction of attention to the spatial location of a visually presented object, as it reflects the initial visual processing and detection of a stimulus. Therefore, option A is the best choice. The other options are associated with different neural processes and ERPs.
