The interplay of attention and consciousness in visual search, attentional blink and working memory consolidation KU Leuven
Despite the acknowledged relationship between consciousness and attention, theories of the two have mostly been developed separately. Moreover, these theories have independently attempted to explain phenomena in which both are likely to interact, such as the attentional blink (AB) and working memory (WM) consolidation. Here, we make an effort to bridge the gap between, on the one hand, a theory of consciousness based on the notion of global ...
Visual and central attention share a capacity limitation when the demands for serial item selection in visual search are high Ghent University

Visual arts training is linked to flexible attention to local and global levels of visual stimuli KU Leuven
Observational drawing skill has been shown to be associated with the ability to focus on local visual details. It is unclear whether superior performance in local processing is indicative of the ability to attend to, and flexibly switch between, local and global levels of visual stimuli. It is also unknown whether these attentional enhancements remain specific to observational drawing skill or are a product of a wide range of artistic ...
With no attention specifically directed to it, rhythmic sound does not automatically facilitate visual task performance Ghent University
In a century where humans and machines-powered by artificial intelligence or not-increasingly work together, it is of interest to understand human processing of multi-sensory stimuli in relation to attention and working memory. This paper explores whether and when supporting visual information with rhythmic auditory stimuli can optimize multi-sensory information processing. In turn, this can make the interaction between humans or between ...
Cortical and subcortical coordination of visual spatial attention revealed by simultaneous EEG-fMRI recording Ghent University
The center-surround profile of the focus of attention arises from recurrent processing in the visual cortex Ghent University
We recently demonstrated with magnetoencephalographic recordings in human observers that the focus of attention in visual search has a spatial profile consisting of a center enhancement surrounded by a narrow zone of sensory attenuation. Here, we report new data from 2 experiments providing insights into the cortical processes that cause the surround attenuation. We show that surround suppression appears in search tasks that require spatial ...
