There is a wealth of literature associating schizophrenia
withdisorders of attention. This study bases on the two-stage
approach of visual selective attention. The pre-
attentiveparallel processcomputes how different each object is
from each of the other objectswithin a particular stimulus
dimension. Attention automatically drawto the location having
the highest activation, implying that the subjects select
location automatically and are irrespective of their intention.
Two Stroop tasks used to differentiate schizophrenics and
nornalic''sattentional processes, and try to figure out which
stageis the caution of schizophrenic''s dysfunctional attention.
As the result, schizophrenic is not different with normalics on
pre-attentiveprocess, but do have something problem
onattentional process when theywhen they have to inhibit some
information. It''sstill not a conclution,because the deficit of
inhibition can not explain the results perfectly.
