Abstract or DescriptionBrain-damaged patients showing extinction are able to process stimuli presented on either hemispace, but fail to report contralesional stimuli when simultaneously presented with an ipsilesional stimulus. Extinction may occur stimuli of the same modality or between stimuli of different modalities (such as visual and tactile). This phenomenon has been interpreted as supramodal imbalance in stimulus competition for attention selection. However, recent studies have reported the existence of a complex interaction of competition-facilitation between visual and tactile information.
