Abstract
A previous study (Roberson, Pak & Hanley, 2008) demonstrated that Korean
(but not English) speakers show Categorical Perception (CP) on a visual search
task for a boundary between two Korean colour categories that is not marked in
English. Moreover, fast Korean responders showed CP only in the right visual
field while slow responders showed CP in both visual fields. The present study
used eye-tracking to demonstrate that those responders who maintained fixation
on a central point showed CP only in the right visual field. Responders who
moved their eyes to search for targets showed the effect in both visual fields.
These results support that CP in this task is mediated by processing in the left
hemisphere.
