Visual Attention and Emotional Perception
Over the past twenty-five years, a great deal has been learned about the neural mechanisms of visual attention. Converging evidence from single-cell recording studies in monkeys and neuroimaging and event-related potential studies in humans have shown that the processing of attended information is enhanced relative to the processing of unattended information. At the same time, there is increasi...
متن کاملDissecting Spatial Visual Attention
it has been recognized that at least two forms of spatial attention can be found in vision. For example, Wundt (1902) observed that attention could be involuntary or voluntary. A variety of distinctions have been made that more or less correspond to Wundt’s distinction, including goal-directed attention versus stimulus-driven capture and endogenous attention versus exogenous attention. the term...
متن کاملHuman cortical mechanisms of visual attention during orienting and search.
Functional anatomical studies indicate that a set of neural signals in parietal and frontal cortex mediates the covert allocation of attention to visual locations across a wide variety of visual tasks. This frontoparietal network includes areas, such as the frontal eye field and supplementary eye field. This anatomical overlap suggests that shifts of attention to visual locations of objects rec...
متن کاملAttention-deficit hyperactivity disorder involves differential cortical processing in a visual spatial attention paradigm.
OBJECTIVE Inattention is undoubtedly one of the main characteristics of Attention-deficit hyperactivity disorder (ADHD). Nevertheless, a growing corpus of evidence shows that not all attentional processes are affected in this condition. This study aimed to explore the distribution of attentional resources in children with ADHD via a spatially shifted double-oddball visual task. METHODS We rec...
متن کاملSpatial and object-based attention modulates broadband high-frequency responses across the human visual cortical hierarchy.
One of the puzzling aspects in the visual attention literature is the discrepancy between electrophysiological and fMRI findings: whereas fMRI studies reveal strong attentional modulation in the earliest visual areas, single-unit and local field potential studies yielded mixed results. In addition, it is not clear to what extent spatial attention effects extend from early to high-order visual a...
