Subjects estimated magnitude of brightness of light under six tone intensities, and loudness of tones under five light intensities. Analysis of results showed significant variance by intensity and subject, under each condition of light and tone. Perceived brightness and loudness increased with each increase in intensity of tone or light. Both brightness and loudness increases were greater in Buddhist than non-Buddhist subjects. Significant correlations indicated that: The greater the score of self-attainment, the greater the brightness and loudness. In contrast with the results of absolute thresholds (previous studies), the present auditory and visual effects did not correlate with the measure of extraversion or arousal, nor exhibit inverted-U function, suggesting a difference between threshold and suprathreshold phenomena. Present results would support the views of intermodality organization.
