Study of Gong tone matching to five colors based on event-related potential

摘要

ObjectiveTo investigate the neural mechanism of Gong tone matching to the five colors.MethodsThe experiment was designed using event-related potential technique, following the S1→S2 paradigm, and dividing into two arms according to the Gong tone being played in harmonics or open strings. For each arm, S1 was the playing of the Gong tone, followed by S2, where subjects, based on their first reaction, were required to make a yeso judgement to whether the tone matches to a randomly-picked color out of the five colors. During this process, the event-related potentials were recorded.ResultsGong tone played in harmonics, most participants matched it with black and cyan; while in the open strings arm, most matched it with black. The average amplitudes of P300 at PZ, FZ, and CZ points were compared. For the Gong tone played in harmonics, there was a significant difference between those who matched it with black and those who did otherwise (P?
