Please answer by selecting exactly one option: A, B, C, or D.\n\nQuestion: In classic P300 theory, which distinction between P3a and P3b is closest to the usual interpretation?\nA. P3a is a frontal muscle artifact, whereas P3b is an occipital alpha rhythm.\nB. P3a is elicited only by auditory stimuli, whereas P3b is elicited only by visual stimuli.\nC. Both P3a and P3b are fixed 300 Hz spectral peaks.\nD. P3a is associated with stimulus-driven attentional orienting, whereas P3b is associated with target processing, attention, and memory updating." | |
