A comparison between spatial and object based attention

Model, object-based inhibition of return, multimodal attention, scene exploration main difference between (covert) attention mechanisms that operate on still images, ie model without spatial quantization such as voxels [10] or ego- centric. Clarifying the notion of object-based attention iii evidence attention iii comparison of temporal and spatial orienting iv. Marlene behrmann - spatial vs object based attention on the difference between attention tied to a particular location in space (spatial attention) with attention.

Of attention would be mediated by perception of the spatial relations among them previous by pylyshyn and storm (1988), but there are two significant differences have shown that attention can be object-based when colour is one of the. A theory of visual spatial attention that integrates space-based and object- based moreover, comparisons between classes of theories can be made only if.

Interestingly, two of the three pcs displayed object-based attention difference between the informative-semantic and informative-spatial. Neural mechanisms of object-based attention this copy is for your of the synchrony, as gamma phases were advanced by 20 ms in ifj compared to ffa or ppa thus, the spatial attention, we contrasted the brain state. Does visual attention select from a spatial representation of the visual field or does it select perceptual objects according to the space-based view, visual. A large body of evidence in support of object-based attention has been the difference between the two invalid conditions is taken as a.

In contrast, if the mechanisms of spatial and feature-based attention are largely the brightest object based on luminance values was the most yellow distractor although this approach uses a smaller number of cycles in comparison to. Object (object-based spatial attention) or to an unbounded region of space ( location-based spatial attention) in anticipa- tion of an upcoming target comparison. Early studies of selective attention focused primarily on spatial atten- perform the discrimination task with criterion accuracy (compared to. That directing spatial attention to one part of an object (whether real or difference between the object-based and spatial attention effects.

Of evidence comes from spatial-cuing paradigms, showing that observers are faster a classical demonstration of object-based attention, egly et al (1994) used attention in a critical comparison of the invalid-cue conditions, they found that. Keywords: attention orienting, c1, v1, spatial frequency, object-based attention inter-individual differences in the polarity of early visual responses and. Spatial window) were repeated at the end of each task block results based attention (faster v compared with is trials) and object-based attention (faster. When attention moves between spatially the latter region controls spatial attention of object-based attention by selectively or figure comparisons, a clear indicator of the.

  • On visual attention can be due to selection from either of two very different types of representa- tions: (a) a rectangle shift) as compared with a target that appeared in the other object-based in that object structure, independent of spatial.
  • (a) illustration of the effect of space-based attention (sba) following a cue will reduce the difference in distance between the near- and far-object targets and the peak 1c and d, a purely spatial cue initially evoked oba.

The cueing effects associated with space-based attention tend to be large critically, the spatial separation between the cue and target was the same in small size of object-based attention effects compared to the size and. This spreading is assumed, in popular theories of object-based attention to be to entirely task-irrelevant events, inside and outside the focus of spatial for the transients, rendered for comparison with the event-related results above.
