Spatial Attention and Saccadic Camera Motion
An important aspect of computer-controlled camera motion systems is that of the generation of saccadic movements, which shift the camera gaze quickly from one xation position to another. Recent psychophysi-cal experiments suggest that there exists a causal connection between spatial shifts in visual attention and the production of saccadic eye movements in humans. Motivated by this experimental...
متن کاملModulation of saccadic intrusions by exogenous and endogenous attention.
Primary gaze fixation in healthy individuals is frequently interrupted by microsaccades and saccadic intrusions (SI). The neural systems responsible for the control of attention and eye movements are believed to overlap and in line with this, the behaviour of microsaccades appears to be affected by exogenous and endogenous attention shifts. In the current work we wished to establish whether SI ...
متن کاملBrief Communications Parietal Stimulation Decouples Spatial and Feature-Based Attention
Everyday visual scenes contain a vast quantity of information, only a fraction of which can guide our behavior. Properties such as the location, color and orientation of stimuli help us extract relevant information from complex scenes (Treisman and Gelade, 1980; Livingstone and Hubel, 1987). But how does the brain coordinate the selection of such different stimulus characteristics? Neuroimaging...
متن کاملControl of spatial and feature-based attention in frontoparietal cortex.
Visual attention selects task-relevant information from scenes to help achieve behavioral goals. Attention can be deployed within multiple domains to select specific spatial locations, features, or objects. Recent evidence has shown that voluntary shifts of attention in multiple domains are consistently associated with transient increases in cortical activity in medial superior parietal lobule,...
متن کاملAdaptive deployment of spatial and feature-based attention before saccades
What you see depends not only on where you are looking but also on where you will look next. The pre-saccadic attention shift is an automatic enhancement of visual sensitivity at the target of the next saccade. We investigated whether and how perceptual factors independent of the oculomotor plan modulate pre-saccadic attention within and across trials. Observers made saccades to one (the target...
