Impaired conflict monitoring near the hands: Neurophysiological evidence.

摘要: Abstract Recent evidence suggests that hand-stimulus proximity enhances the visuo-motor Simon effect. The present study used event-related potentials (ERP) to examine timing at which modulates results show P1 and N1 components were not modulated by proximity, suggesting early sensory processing is altered proximity. However, interference effect (the difference between incompatible versus compatible trials) on N2 component was significantly attenuated near hands compared far from hands, indicating impairs conflict monitoring. We also found significant effects a later component, as P3 reduced had shorter latency for hand-proximal condition relative hand-distal condition. These new findings suggest critical stage affects cognitive lies past perceptual processing, acting instead stages of related executive functioning.
