One of the functions of visual attention is the selection of object information this seems to be in line with an influential group of attentional models that assume that attentional selection is space based these models assume that the selection of an object in vision is realized by selection of . Visit the apa books homepage to browse or search for other books this volume represents the state of the art in research on visual selective attention, with a focus on the broad theme of converging operations in 19 chapters, prominent scholars in the study of visual attention bring readers up to .

A comparison of space-based and object-based models of visual attention selective attention and the organization of visual information. Recurrent models of visual attention and develop a novel framework for attention-based task-driven visual processing with neural networks a hidden space . Simulation of space-based and object-based effects of spatial cueing in the selective attention for identification model panel a: the stimuli and presentation times (the cue was a small square and the target an arrow). Space and selective attention article (pdf available) in attention and performance vol 15 january 1994 with 134 reads cite this publication.
Computational models of visual selective attention: a review have dictated much of the psychological research on visual attention space vs object-based attention. Rewards teach visual selective attention participants are likely doing their best to harvest as much as possible of the available reward based effects on . Visual selective attention is a fundamental cognitive ability that allows us to process relevant visual stimuli while ignoring irrelevant distracters and has been extensively studied in human and non-human primate subjects. Er-based selective visual attention test (s evat): the parallel form of the com-puter-basedsevat was designed toim-prove the test reliability and eliminate the carry . Visual attention can be primarily allocated to either where an object is in space (with little emphasis on the structure of the object itself) or to the structure of the object (with little emphasis on where in space the object is located).
The neural basis of selective attention visual attention, feature-based attention, by far the most studied domain of selective attention is visual space . Working memory, selective visual attention, selective visual attention – top-down vs bottom-up 2 space-based and object-based attention - psychological and . Space-based visual attention: a marker of immature selective attention in toddlers of space-based attention over object-based attention could be a marker of . Based on these findings, it has been argued that auditory deprivation results in deficient visual selective attention, with deaf individuals being unable to differentiate task-relevant from task-irrelevant information in contrast, as we explore here, deaf individuals may excel on tasks that require differentiating task-relevant from task .
Driver object-based accounts of visual attention 65 the issue of perceptual grouping relates to much recent debate about whether visual attention should be thought of as space-based or object-basedg as described earlier there are many examples of a rival view as with eye movements. Is how we direct selective attention best explained by the spotlight model, the obj-based model, or the attribute-based view-- how do we choose what to conciously pay attention to do we look for what is in a certain location in space, certain obj, or elements of objs. Method leading to the automatic choice of the best fea- [15,16] is a bottom-up selective visual attention based on serially scanning a saliency map that. Selective attention and visual organization 503 an object-based theory limits on our ability to see several things at once may reflect both difficulties in dealing with several objects and. Selective attention is the ability to select from many factors or stimuli and to focus on only the one that you want while filtering out other distractions alternating attention is the ability to switch your focus back and forth between tasks that require different cognitive demands.
The spotlight model of selective attention was developed by david laberge, based on work carried out by william james the theory describes attention as having a margin, fringe and focus the focus point is where our attention is directed, the fringe is an area of low level attention, and the margin is the cut off point beyond which we pay no . Space based visual attention is when we attend to a certain area of space this may be for several reasons (eg hearing a noise)in the past 30 years of so there has been much research conducted into this area, mostly using lab based computer experiments, manipulating cues and targets to see how we react to and process them. We investigated the interaction between object- and space-based attention by measuring activity in early visual cortex after central cueing, when subjects directed attention to a spatially defined part of an object, activity in early visual areas was enhanced at corresponding retinotopic .
The selective processing of some visual stimuli (targets) in favor of others (distracters), according to their component features, identity, location within visual space or physical salience covert attention. And looking for the best approxi- “hot spot detection based on feature space active contours based on selective visual attention,”. Space-based visual attention models and object selection: relatively simple idea of space-based attention and the what is selective attention frequently, an . Object-based attention refers to the relationship between an ‘object’ representation and a person’s visually stimulated, selective attention, as opposed to a relationship involving either a spatial or a feature representation although these types of selective attention are not necessarily mutually exclusive.
To the best of our knowledge, this is the first evidence that patients with crps have diminished attention to the affected compared to the unaffected side of space in terms of their general sensory processing (ie independent of visual or tactile bodily information).
