Abstract
It is widely accepted that the left and right hemispheres differ with respect to the processing of global and local aspects of visual stimuli Recently behavioural experiments have shown that this processing asymmetry strongly depends on the response competition between the global and local levels of a stimulus Here we report electrophysiological data that underline this observation Hemispheric differences for global/local processing were mainly observed for responseincompatible stimuli and were most prominent between 320 and 400 ms after stimulus onset These results underpin the idea that hemispheric differences are more likely to show up when a more elaborated stimulus representation is needed for triggering the response that is when a response conflict has to be resolved
