teacher and children during English CLASSES at an elementary school. The analysis of the class,
which was observed, focuses on whether the speaker and the listener synchronized with each other
or opposite. The latter relationship is based on Bakhtin’s dialogic narratives and the former is on
Yamada’s coexistent narratives. Sato (1999) analyzed a classroom discourse at an elementary
school from the standpoint of the latter relationship. In this paper the theoretical features of the
coexistent narratives are analyzed in the classroom discourse of English at an elementary.
1063.101 Recognition memory for Chinese words and common objects:a event-related potential
study, Wang Xiang, Cheng Zaohuo, Yao Shuqiao, Wu Daxing, Shi Chuan, Central South
University, Changsha, China
Objects: To study the ERPs correlates of memory retrieval for Chinese words and pictures of
common objects. Method: 21 volunteers received two recognition tasks respectively, and the ERPs
were recorded from 18 scalp sites. Result: For both stimulus ERPs elicited by recognized items
contained the parietal old/new effect, and that of pictures was larger than words. The N400
old/new effects showed some differences mainly in the frontal scalp regions. Furthermore, it
demonstrated a negative shift in the words recognition. Conclusion: Recognition of words and
pictures share some of the same neural substrates, but there were still some differences between
them.
1063.102 The information transportation system of brain: A possible memory system theory, Fei
Peng, Shaanxi Normal University, China
This paper presents there must have one kind of organs similar to CPU in the brain. Memory is a
process in circle: receiving information by sense, retrieving former information from memory
system, processing information by “CPU” in the brain, saving final information in memory system,
feeding back final information by behavior system from the moment of birth to death. There are
two different information transportation systems, one has high speed, low precision, the other has
low speed, high precision. That leads to a clear distinction between implicit and explicit memory
systems in the brain.

Normal University, China
This study investigated the subsequent memory effects (DM) of high frequency characters, low
frequency characters, pseudo-characters and non-characters. Eighteen college students participated
in this experiment. The Event-related potential (ERPs) were recorded when they were deciding
weather a character is true or not. The DM effect were found in high frequency characters, low
frequency characters and non-characters. The later positive component (LPC) evoked by the
recognized items is more positive-going than that by the unrecognized. Dm effect elicited by
non-characters ranges from 140ms to 240ms. The results were discussed in terms of role of
semantic access of character in Dm effect.
