The Influences of Perceptual Grouping on the Temporal Dimension of Auditory Events

In this research, it was hypothesized the influence of the vertical segregation of an event on the global duration of the auditory sequences. Two experiments were carried out in which the method of adjustment was used. The result of the first experiment shows that the stimulus onset asynchrony-within decreases when an “empty” interval is placed between two sounds. The result of second experiment shows a reduction of perceptual duration in sequences with vertical segregation of the white noise. These results suggest that temporal dimension of the auditory sequences is related to the perceptual grouping.
