Editing Stroop effect (section)

=== Spatial ===
The spatial Stroop effect demonstrates interference between the stimulus location with the location in the stimuli.<ref name="Wuhr 2007 285–294">{{cite journal|last=Wuhr|first=P|title=A Stroop Effect For Spatial Orientation|journal=The Journal of General Psychology|year=2007|volume=134|issue=3|pages=285–294|doi=10.3200/genp.134.3.285-294|pmid=17824399|s2cid=2872079}}</ref>  In one version of the spatial Stroop task, an up or down-pointing arrow appears randomly above or below a central point. Despite being asked to discriminate the direction of the arrow while ignoring its location, individuals typically make faster and more accurate responses to congruent stimuli (i.e., a down-pointing arrow located below the fixation sign) than to incongruent ones (i.e., an up-pointing arrow located below the fixation sign).<ref name="Wuhr 2007 285–294"/>  A similar effect, the [[Simon effect]], uses non-spatial stimuli.<ref name="Johnson 2004"/>
