abstract = {Comparing experts with novices offers unique insights into
the functioning of cognition based on the maximization of
individual differences Here we used this expertise approach
to disentangle the mechanisms and neural basis behind two
processes that contribute to everyday expertise object and
pattern recognition We compared chess experts and novices
performing chess related and unrelated (visual) search tasks
As expected the superiority of experts was limited to the
chess specific task as there were no differences in a
control task that used the same chess stimuli but did not
require chess specific recognition The analysis of eye
movements showed that experts immediately and exclusively
focused on the relevant aspects in the chess task whereas
novices also examined irrelevant aspects With random chess
positions when pattern knowledge could not be used to guide
perception experts nevertheless maintained an advantage
Experts superior domain specific parafoveal vision a
consequence of their knowledge about individual domain
specific symbols enabled Improved object recognition
Functional magnetic resonance imaging corroborated this
differentiation between object and pattern recognition and
showed that chess specific object recognition was
accompanied by bilateral activation of the occipitotemporal
junction whereas chess specific pattern recognition was
related to bilateral activations in the middle part of the
collateral sulci Using the expertise approach together with
carefully chosen controls and multiple dependent measures we
identified object and pattern recognition as two essential
cognitive processes in expert visual cognition which may
also help to explain the mechanisms of everyday perception},
