Abstract
We have studied the interference of irrelevant information on the visual selective attention and whether load effects are modality specific or can be obtained across the visual and auditory modalities.
Highlights
The selective or focused attention to a particular stimulus implies that the subject ought to ignore each other stimuli
Experimental evidences have led to several attentional models, which suggest that attention acts like an adjustable focus to relevant stimuli
Further insight into the attentional process might come from the study of the influence of the perceptual load and whether or no the visual focus is specific to visual stimuli as was pointed out by Cowan et al [3] saying that “the focus covers all modalities and codes”
Summary
The selective or focused attention to a particular stimulus implies that the subject ought to ignore each other stimuli. There are many evidences about the limited processing capacity for stimuli presented within the same sensory modality and a relevant question to study is whether similar limitations appear when the stimuli are presented across different modalities. This topic is relevant to many recent studies on working memory and on the control of attention, including the ability to avoid distraction by irrelevant stimuli [9,10,11,12,13]. We have studied the influence of the visual load in the absence and presence of the acoustic stimuli
