The present study examines whether or not the subjectively preferred tempo responding to periodic noise-bursts reflects the temporal information in continuous brain waves (CBW). The experimental condition was designed to examine: (1) the hemispheric specialization on as temporal aspect, (2) a relationship between subjective preference and the effective duration (τ_e) of the autocorrelation function (ACF) in α-waves range. According to the results of the paired-comparison tests, the most preferred period was found around 550 ms. From the analysis of the τ_e values in α-waves range, the hemispheric difference is identified by periodic effects (p < 0.001) which were obtained only in the left hemispheres at periods of 550 ms, referred to 300 ms and 1,000 ms. The global results also show the significantly periodic effects (p < 0.001) are thoroughly found in both periodic pairs.
