Holistic processing (HP) has been proposed to be a characteristic
of right hemisphere (RH) processing. Here we test this
claim using the divided visual field paradigm with Chinese
character stimuli. HP is assessed through the composite paradigm,
which is commonly used in perceptual expertise research.
We found that in novice Chinese readers, a standard
HP pattern emerged only in the left visual field/RH but not in
the right visual field/left hemisphere, consistent with the analytic/
holistic hemispheric dichotomy in the literature. However,
in expert Chinese readers, neither visual field showed the
HP pattern, consistent with the finding that reduced HP is an
expertise maker for Chinese character recognition. Thus, the
RH does not always employ holistic processing; it depends on
the perceivers’ experience with the stimuli. This is the first
study demonstrating that expertise with a visual object type
can modulate hemispheric difference in HP.
