영문 초록

Event related potentials(ERP) were measured in thirty one normal controls(32.9士 6.3 in average age), while two kinds of stimuli, frequent and infrequent stimuli were given with an instruction(for counting infrequent stimuli), without an instruction. The amplitudes on N l, P2, P3 were significantly higher with infrequent stimuli than with frequent stimuli in ignoring condition. In instructed condition, the significantly higher amplitudes in PI, N l, P3 components were noted with infrequent stimuli than with frequent stimuli. The amplitude of P3 increased most prominently in an attending condition comparing to an ignoring condition. Good performers of this task showed significantly higher amplitudes in N l and P3 than bad performers.
