extending over a longer time window and tone occurring on one syllable. Using functional
magnetic resonance imaging (fMRI), this study compared Chinese speakers’ processing of
Chinese intonation (statement/question judgment) in short (one-word) and long sentences, and
tones in word and sentence contexts. Results show that intonation, regardless of length, is
processed differently than tone, indicating that linguistic function rather than temporal frame
length is a factor determining hemispheric activation patterns.

This study used functional MRI to investigate the brain activations as ten bilingual
(Chinese-English) participants naming pictures in one language or discriminating words in two
languages. Activation patterns for naming pictures by Chinese characters or English words are
similar. Compared to the picture naming tasks, the two-language words discrimination task
induced significant activations in left middle frontal gyrus (GFm, BA9/45) and left fusiform gyrus
(BA19). These findings suggested that Chinese and English naming tasks in bilinguals involve
overlapping brain activations and the left GFm plays a key role in the transformation of Chinese
characters and English words.
2028.147 An investigation of the neural basis of conscious and unconscious priming effect using
the process dissociation procedure and fMRI, Atsushi Matsumoto, Tetsuya Iidaka, Graduate
school of environmental studies, Nagoya University, Japan
Recent neuroimaging studies have revealed that repetition priming causes a reduction of the
activity in the brain regions such as the left infero-temporal cortex and the left inferior frontal
cortex while the activity in several regions was increased by priming. However, the results of
these studies have possibly failed to dissociate the conscious and unconscious priming effect. We
employed event-related functional MRI study to investigate the neural substrates of conscious and
unconscious priming effect using the process dissociation procedure. This procedure enabled us to
strictly dissociate the brain region concerning the conscious and unconscious priming effect.

A prediction error occurs when an outcome fails to meet an expectation. Prediction errors have
been proposed to elicit learning in current theories of conditioning. A formal test came from the
blocking paradigm where a fully predicted reinforcer blocks a new stimulus from forming an
association with the reinforcer. We found that the ventral pallidum was more activated by a reward
predicting stimulus than by a neutral stimulus, showed learning related activity changes and was
more activated by a non-blocked control stimulus than by a blocked stimulus, suggesting a role of
the ventral pallidum in reward learning.
