1098.93 Electrophysiological estimates of the time course of semantic, orthographic and
phonological encoding during implicit Chinese monosyllabic word production, Qingfang Zhang,
Yufang Yang, Institute of Psychology, Chinese Academy of Sciences, Beijing, China
Two different event-related potential (ERP) components were used to investigate the time course
of lexical access during implicit Chinese monosyllabic word production. Participants were shown
pictures and carried out a dual choice go/nogo decision based on semantic information and
orthographic information (Experiment 1), or the orthographic information and phonological
information (Experiment 2). Both the lateralized readiness potential (LRP; related to response
preparation) and N200 (presumably related to response inhibition) indicated that semantic
activation occurs earlier than orthographic and phonological processing. In addition, compared to
the phonological processing, the orthographic encoding appears relatively early.
1098.94 Influence of pre-composition planning time on the pre-composition planning effect,
Miao Liu, Biyin Zhang, China
This paper attempts to study the influence of pre-composition planning time on the
pre-composition planning effect by the method of combining natural experiment and laboratory
experiment. Our study discovers that the composition form determines the planning time, which in
turn influences the planning effect, which then determines the composition form. This indicates
that with both the plan and the external representation, the plan itself plays a decisive role in the
relations between the limited time for planning and the planning form. A more complicated case
about the effect of the external representation emerged when the plan exists.
1098.95 Lexicalization of idioms in people with schizophrenia, Yamazaki Ikuo, Shimizu
Hajime, Hiroshima University, Japan
Lexicalization is a key feature of language use. If lexicalization is not sufficient in certain
language, we cannot use that language fluently. People with schizophrenia have language
dysfunction in various aspects, in which dysfunction of lexicalization has seldom been
investigated. An important facet of lexicalization is knowledge of idioms, which are frequently
used in everyday conversation and important for practical language use. Ten male people with
schizophrenia were tested on two kinds of idiom test; multiple choice task (338 idioms) and
completion task (278 idioms). Results showed better scores on multiple choice task than on
completion task and correlation with general language ability.
1098.96 The role of the discourse focus in the processing of demonstrative NPs, Marion
Fossard 1 , Alan Garnham 2 , H. Wind Cowles 2 , 1 Université Toulouse le Mirail, France; 2 Sussex
University, UK
In four experiments using off-line and on-line methodologies, we investigated the role of the
discourse focus in the processing of the demonstrative 'that N'. by studying this expression in
contrast with two other expression types: the pronoun (he/she) and the repeated noun, we showed
that only the demonstrative NP is specialized in accessing less salient referents. Contrary to the
ordinary pronoun which serves to signal referential and attentional continuity, and unlike the
repeated noun which is not sensitive to the focusing entity constraint, the demonstrative appears to
be a specific marker serving to signal a new orientation within the discourse.
