Research Abstract

In order do determine the time course and neural processes involved in online word segmentation and statistical learning of visual sequence, we recorded event-related potentials(ERPs). The results suggested that the N400 effect indicated online segmentation of the visual sequence and the degree of statistical learning as well as the auditory sequence learning processes. Our results also imply that statistical learning represents a common learning device.
