Description

Event-related potentials (ERPs) were studied with the oddball tone sequence paradigm in the non-task condition and the task condition for each 12 college students. N100, P200, P300 and mismatch negativity (MMN) were obtained in the non-task condition as well as in the task condition. In the non-task condition, N100 had a significantly higher amplitude following rare stimuli than that following frequent stimuli. P200 also showed a higher amplitude, although not significant, following rare stimuli. These results might reflect the detection of deviant stimuli (rare stimuli). The waveform and latency of P300 component in the non-task condition were similar to those in the task condition. No laterality effect was found in any of components. Posture change (sitting and supine) did not affect the ERP results. It was suggested that combined investigation of P300 with other components might give more precise information in the non-task condition as well as in the task condition, in terms of applied physiological psychology.
