Human spoken language has a two-layered hierarchical segment structure (Double Articulation Structure) universally. This structure is thought to exist not only in spoken language but also in human actions, In order for the Double Articulation Structure to be processed, it is thought that any part of the brain is responsible for its function, but it is not yet clear which part of the brain it is.
On the other hand, previous studies have shown that humans can extract appropriate structures and cohesions from continuous stimuli, but no attention has been paid to the differences in the modalities of input stimuli, and double segmented Modality dependence in cognitive processes has not been taken into account. In addition, despite the similarity of the stimulus structures used in these studies, the segmentation results differed, and thus different modalities did not. The learning mechanism itself may be different.
In this study, we hypothesized that different modalities were segmented by different mechanisms. To verify this, we called pitch, Japanese vowels, shape change of figure, and position change of figure under the same conditions. Behavioral experiments using four types of stimuli confirmed that there was a difference in performance between modalities.
