Space contraction experiences during acoustic metronomic stimulation: a synthetic discussion

On the basis of the results of a previous research, we will present a new interpretation of some psychophysiological component of spatial experience. The research examined the role of the acoustic activity of a metronome (with different frequencies of 66, 144, 192/min) on a space estimation between two points. The stimulus distances between the points were 30, 60, 90 cm. Increasing the metronomic frequency determines an evident contraction of the estimation of the perceived distances for each of the three different stimulus distances. The results have been interpreted in light of a psychophysiological integrated model.
