Research Abstract

In this study, we found that Japanese infants did not show word segmentation abilities stably by learning transitional probability between supra-segments (statistical learning), by which 8 months old infants in English-speaking countries showed the abilities in previous studies, and that their segmentation is depended on sound stimuli. Instead of the statistical learning, we found that human adults have ability to extract deterministic causality embedded in continuous variation in sound sequences. We also established experimental techniques for stable measurement of EEG from awaked infants.
